EPC1441LC20 Overview
A configuration PROM is a specialized nonvolatile memory IC that stores the bitstream required by an SRAM-based programmable logic device. Because SRAM-based FPGAs lose their logic configuration when power is removed, the configuration controller reads the PROM during startup and transfers the stored data to the target device. The hierarchy is configuration PROM -> nonvolatile memory -> FPGA configuration memory -> FPGA and CPLD support component. EPC1441LC20 belongs to Altera’s EPC14 configuration-device family, historically used for SRAM-based LUT devices.
The principal identified feature is 440 kb of configuration memory, supplied in a 20-PLCC (9x9) package. Search references identify an 8 MHz configuration-memory performance value, while one distributor listing describes the device as a serial configuration memory. The one-time-programmable nature allows the configuration image to be stored before system operation, after which the PROM can provide the startup bitstream without a separate external programming port during normal operation. These characteristics make the part relevant to legacy FPGA boards, replacement systems, and designs requiring deterministic configuration storage.
In a typical design, the EPC1441LC20 is connected to the FPGA configuration interface and selected during the device’s configuration cycle. The FPGA configuration controller reads the serial data and writes it into the SRAM-based logic fabric. The 8 MHz figure is a useful system-level timing reference, but the final configuration time depends on the target FPGA, interface mode, PROM setup, board loading, and controller behavior. Engineers should therefore use the complete device documentation and target-FPGA configuration timing information rather than treating the PROM figure as the only end-to-end timing value.
Common applications include SRAM-based FPGA configuration, industrial control equipment with legacy Altera devices, communications or test equipment using programmable logic, and board-level replacement or repair. The 20-pin PLCC package is important for legacy footprints and should be checked against the PCB land pattern and pin numbering before procurement. Commercial-temperature operation from 0 °C to 70 °C is explicitly reported in the supplied Kynix listing, but voltage, current, interface voltage, programming procedure, and absolute maximum ratings require confirmation from the manufacturer datasheet.
For new designs, verify whether the FPGA can use a compatible configuration source, whether the EPC1441LC20 has sufficient capacity for the generated bitstream, and whether the board provides the required reset, configuration-clock, data, and handshake signals. The package and pinout must be cross-checked against the original design and the latest manufacturer documentation. Pricing and availability are time-sensitive; the supplied distributor search result states “Buy now, ships today,” but current stock and lead time should be confirmed with the distributor before release to production.
This product data combines verified web specifications, package and temperature information, pricing availability signals, application context, and engineering considerations. It is intended to support component selection, legacy-board maintenance, and informed sourcing while marking unverified electrical characteristics as data-needed rather than guessing them.

Typical Applications
EPC1441LC20 is suitable for 6 applications: SRAM-Based FPGA Configuration, Legacy Industrial Control Equipment, Communications Equipment, Test and Measurement Systems, Board Repair and Configuration Replacement, Embedded System Prototyping.
SRAM-Based FPGA Configuration
EPC1441LC20 is suited to storing the configuration bitstream for an SRAM-based FPGA or LUT device. Its verified 440 kb capacity, serial configuration role, 8 MHz listed performance, and 20-PLCC package provide a compact legacy-oriented configuration solution. The FPGA controller reads the PROM after power-up and transfers the stored data into the programmable logic fabric. The 8 MHz figure is a component-level reference; actual system configuration time also depends on the FPGA density, interface mode, board loading, and controller timing. The 0 °C to 70 °C commercial temperature range is relevant for equipment operated in controlled environments. Before adoption, confirm that the generated bitstream fits the PROM capacity and that the FPGA configuration interface, reset sequence, and clock requirements match the manufacturer documentation.
Recommended
Legacy Industrial Control Equipment
EPC1441LC20 can support repair, maintenance, and redesign work for industrial control equipment built around Altera SRAM-based programmable logic. The 20-PLCC, 9 mm by 9 mm package is especially useful when an existing board already provides that footprint, while the serial configuration function preserves the historical architecture. The listed 8 MHz performance helps characterize the configuration path, but the overall startup sequence must be validated with the specific FPGA and board controller. The 0 °C to 70 °C range is a commercial rating, not an industrial-temperature qualification. Designers should therefore assess enclosure temperature, airflow, maintenance environment, and required service life separately. For obsolete or long-life equipment, confirm current availability and consider approved inventory, lot traceability, and configuration-image verification before production release.
Recommended
Communications Equipment
EPC1441LC20 is applicable to communications equipment that uses SRAM-based FPGA devices and requires nonvolatile startup configuration. The 440 kb memory capacity, serial interface, and 8 MHz listed performance provide a defined configuration-memory role for boards where deterministic reload after power cycling is required. The 20-PLCC package supports legacy or space-constrained layouts, but routing must preserve the configuration-clock, configuration-data, reset, and status signals specified by the FPGA. Communications-system operation may also impose strict boot-time, signal-integrity, and environmental requirements beyond the PROM’s basic memory role. The supplied data verifies a commercial range of 0 °C to 70 °C but does not provide supply voltage, current, jitter, programming, or compliance details. Those values must be obtained from the current manufacturer datasheet before using the part in a new communications design.
Recommended
Test and Measurement Systems
EPC1441LC20 can provide configuration storage in test and measurement systems that depend on SRAM-based FPGA logic for signal processing, control, or instrument functions. The serial configuration format and 440 kb capacity make the part a focused solution for loading a known FPGA image at startup or after a system reset. The listed 8 MHz performance is useful for initial timing analysis, while end-to-end boot duration must include the target FPGA configuration architecture and any additional initialization stages. The 20-PLCC package allows replacement work on existing designs but requires careful footprint and pinout review for new layouts. The verified commercial temperature range is 0 °C to 70 °C, so laboratory or production environments with higher temperatures may need a separately qualified configuration device. Confirm programming support, configuration waveform timing, and electrical limits using the manufacturer’s current documentation.
Recommended
Board Repair and Configuration Replacement
EPC1441LC20 is particularly relevant to board-repair, configuration-memory replacement, and legacy FPGA-system restoration. The verified package is a 20-PLCC device with 20 terminals, and the supplied cross-reference data identifies several Altera EPC-family candidates. A repair engineer should not infer equivalence from a family name or package alone: compare the exact suffix, package drawing, pinout, memory capacity, interface timing, temperature grade, and programming process. The target device’s 440 kb capacity and 8 MHz listed performance are known from the supplied web results, while equivalent-part characteristics remain incomplete. A successful replacement must reproduce the original configuration image and startup behavior. Inspect the PCB for socket type, pin-1 orientation, lead condition, contamination, and configuration-signal integrity. After installation, verify the FPGA enters user mode reliably across power cycles and reset conditions.
Recommended
Embedded System Prototyping
EPC1441LC20 can be used in embedded-system prototypes that employ SRAM-based FPGA logic and need a dedicated nonvolatile configuration source. The 440 kb capacity supports moderate configuration images, while the 20-PLCC package provides a familiar through-hole-ish legacy assembly format suitable for prototype replacement and rework. The serial configuration architecture simplifies the conceptual connection to the FPGA configuration controller, but the board still needs correct reset, clock, data, and status timing. The 8 MHz figure provides a starting point for configuration-time calculations, not a complete system timing guarantee. The verified commercial range is 0 °C to 70 °C, and no industrial qualification is stated. Prototype teams should validate the complete power sequence, PROM programming procedure, bitstream size, signal integrity, and repeatability across cold start, warm reset, and repeated configuration cycles before finalizing the design.

Design Notes
Use the manufacturer datasheet to confirm the EPC1441LC20 supply-voltage range, current consumption, power-up behavior, and absolute maximum ratings; these values are not present in the supplied web data. Place the device’s decoupling network close to the supply pins and follow the reference design for the selected FPGA. Verify that reset, configuration-clock, configuration-data, and status timing remain valid across the full supported temperature range. Do not infer power integrity from the 8 MHz performance figure, because that figure describes configuration performance rather than total system power or current demand.
Treat the 20-PLCC footprint and pin numbering as a controlled legacy-layout element. Confirm the PLCC land pattern, pin-1 orientation, socket or direct-mount method, and keepout requirements from the current package drawing. Route configuration signals with short, controlled paths and avoid coupling from clocks, switch-node edges, or other high-current traces. Because a complete pinout was not included in the verified results, the engineer must verify every pin against the official datasheet before schematic capture, PCB fabrication, or replacement procurement.
Do not select a replacement solely because its MPN begins with EPC or because a listing states that it is similar. EPC1442LC20, EPC1441LC20N, EPC1213LC20, and EPC1064LC20 appear in the supplied search results, but their exact memory capacity, pinout, timing, temperature grade, and programming behavior are not fully verified. Check the full part number suffix, package marking, configuration interface, and target-FPGA compatibility. A 70% parametric match is not proof of electrical or pin compatibility; use the manufacturer cross-reference and approved replacement documentation for release decisions.
Validate configuration-clock and configuration-data timing at the FPGA pins, not only at the PROM pins. The listed 8 MHz value is a useful starting reference, but propagation delay, FPGA input timing, board capacitance, reset sequencing, and signal slew can affect reliable configuration. Measure or simulate startup behavior across power-on, power-cycle, warm-reset, and repeated configuration scenarios. Inspect the waveform for overshoot, ringing, and missing edges, especially when using adapters, sockets, or long replacement cables. Confirm that the target FPGA recognizes the PROM and reaches user mode without intermittent configuration errors.
Compliance Information
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 compliance. The operating temperature is listed as 0 °C to 70 °C, but that does not establish AEC-Q100 qualification. Confirm compliance with the manufacturer or authorized distributor documentation.
