EPF6024AQI208-2 Overview
What is a PLD? A Programmable Logic Device is a generic term for a digital IC whose logic function and interconnect are defined after manufacture by the end user. PLDs sit within the broader taxonomy of programmable logic: simple PLD (SPLD, e.g. PAL/GAL) -> complex PLD (CPLD) -> field-programmable gate array (FPGA), with FPGAs occupying the highest density tier. The FLEX 6000 series occupies the CPLD/early-FPGA boundary, optimized for high I/O count and predictable timing rather than register-rich datapath synthesis.
Key features of the EPF6024AQI208-2 include a maximum clock frequency of 153 MHz, in-system programmability via SRAM configuration cells (requiring a configuration device on power-up), 5 V tolerant I/O (the 'I' speed grade), and an industrial operating temperature range of -40 C to +85 C. Embedded array blocks (EABs) provide on-chip ROM/RAM for look-up tables and small FIFOs, while each logic element contains a 4-input look-up table and a programmable flip-flop.
Architecturally the FLEX 6000 uses a continuous-routing FastTrack interconnect that delivers predictable, compiler-driven delay rather than the segmented routing of later FPGA families. This makes timing closure straightforward at the cost of slightly higher propagation delay per gate compared with Look-Up-Table FPGAs of the same vintage. The PQFP-208 footprint offers through-hole-compatible hand-solderability for prototype and legacy repair, in contrast with the BGA-only options of later Cyclone families.
Typical applications include industrial glue logic replacement, bus-interface bridges (e.g. PCI/ISA to local microcontroller), motor-control state machines, legacy telecom backplane glue, and instrumentation front-ends where 5 V I/O tolerance simplifies interfacing to analog front ends. The high I/O count (171 user I/O plus 4 dedicated inputs) suits designs that previously required multiple 84-pin PLDs.
When designing with this part, note that FLEX 6000 devices are SRAM-based and lose configuration on power-down; pair with an Altera EPC configuration PROM (EPC1441/EPC1) for non-volatile boot. The PQFP-208 package requires a 1.2 mm pitch PCB footprint with a 30.6 mm body and exposed lead fingers - allocate at least four PCB layers for clean power and ground return paths beneath the package.

Typical Applications
EPF6024AQI208-2 is suitable for 6 applications: Industrial Bus Interface Bridge, Motor Control State Machine, Legacy Telecom Backplane Glue, Test and Measurement Front-End, Avionics Databus Interface (Legacy), Medical Imaging Pre-Processor.
Industrial Bus Interface Bridge
The EPF6024AQI208-2 bridges legacy 5 V parallel buses (ISA, PC/104, VME) to modern microcontrollers in industrial controllers. Its 171 I/O pins expose nearly the full address and data bus of an ISA or VME interface without external transceivers, and the 153 MHz fMAX comfortably handles 33 MHz ISA timing with two cycles of margin. Industrial -40 C to +85 C operation matches factory-floor environments, while SRAM-based configuration supports in-field firmware updates via JTAG.
Recommended
Motor Control State Machine
The EPF6024AQI208-2 serves as the central state machine and PWM generator in multi-axis motor drives. Its 1,960 logic elements absorb encoder decoding, commutation lookup, and protection logic in a single chip, while 171 I/O lines drive gate-driver enables and read back Hall sensors. The 153 MHz internal clock supports 16-bit PWM at 50 kHz with 11-bit resolution, and the industrial temperature range tolerates the thermal envelope of an enclosed drive cabinet.
Recommended
Legacy Telecom Backplane Glue
In legacy telecom backplanes the EPF6024AQI208-2 replaces multiple 22V10 GALs and discrete 74-series glue logic on a single PQFP-208 footprint. Its high I/O count accommodates HDLC framing, timeslot interchange, and alarm-scan logic simultaneously. The SRAM configuration can be updated remotely over JTAG to deploy new framing protocols without board swap. The 5 V-tolerant I/Os connect directly to legacy TTL buses without level shifters.
Recommended
Test and Measurement Front-End
The EPF6024AQI208-2 implements trigger logic, timing generators, and channel-multiplexer control in bench-top oscilloscopes and logic analyzers. Its 171 I/Os drive dozens of analog switches and read back comparator thresholds, while the 153 MHz clock supports sub-nanosecond timing resolution. Industrial temperature range supports lab and light-industrial use. SRAM configurability lets OEMs ship a single board and customize the instrument personality at the factory.
Recommended
Avionics Databus Interface (Legacy)
Older avionics designs use the EPF6024AQI208-2 as an ARINC 429 / MIL-STD-1553 channel arbiter and discrete-to-bus converter. The 171 I/Os handle up to 16 ARINC 429 receive channels plus discrete discretes in a single device, eliminating a backplane full of discrete logic. Industrial temperature range is acceptable for cockpit equipment bays; note that DO-254 certifiable variants require formal DER review of the configuration bitstream. PQFP-208 footprint is hand-solderable for legacy repair depots.
Recommended
Medical Imaging Pre-Processor
The EPF6024AQI208-2 serves as the pre-processor in ultrasound and endoscopy imaging carts, conditioning analog front-end data before passing to a host processor. Its 1,960 LEs implement FIR filters and beamforming accumulators, while 171 I/Os interface to multi-channel ADC banks. Industrial temperature range suits cart environments; SRAM configuration enables OEM-specific image-processing pipelines shipped on a single hardware platform.

Key Differentiators
- Highest-density FLEX 6000 in PQFP-208 (vs EPF6016AQI208-2)
- Industrial temperature range at full density (vs EPF6024AQI208-1)
- Faster -2 speed grade (vs EPF6016QI208-3)
Design Notes
The PQFP-208 footprint has a 0.500 mm lead pitch and a 30.6 mm body. Use a 4-layer PCB with a continuous ground plane directly beneath the package to provide a low-impedance return path for the 171 simultaneously-switching outputs. Decouple each VCCINT pin with a 0.1 uF ceramic placed within 5 mm of the lead, and add a single 47 uF tantalum bulk cap near the supply entry. Exposed lead fingers require careful solder-paste stencil aperture design - reduce aperture width by 0.05 mm to prevent solder bridges on the fine-pitch gull-wing leads.
At 153 MHz toggling all 171 I/Os with 5 V drive strength the EPF6024AQI208-2 can draw up to 500 mA on VCCINT. Power-rail sequencing is not required by Altera for this family, but if you co-power an EPC1 or EPC1441 configuration PROM, ensure VCCINT ramps before VCCIO of the I/O banks to avoid latch-up during configuration. Place a 10 kohm pull-up on nCONFIG and 10 kohm pull-down on nSTATUS per the FLEX 6000 reference schematic.
Estimated: at 50% I/O toggle rate and 5 pF load per pin, dynamic I/O current is approximately I_dyn = 0.5 * 171 * 5 V * 5 pF * 153 MHz = 0.33 A. Add this to the static core current of about 0.15 A for a total VCCINT budget near 0.5 A. Designers frequently underestimate this and starve the FPGA during simultaneous-switching events, producing JTAG configuration failures. Always validate with a scope on VCCINT during in-system programming.
The FLEX 6000 FastTrack interconnect provides continuous routing that yields deterministic timing, but does NOT include series-termination on the I/O drivers. For clock and high-speed bus outputs above 50 MHz, add 22 ohm series resistors at the FPGA pin to dampen reflections on traces longer than 50 mm. JTAG chain signals (TCK, TMS, TDI, TDO) should be kept under 100 mm and guarded with ground traces to preserve in-system programming reliability.
Compliance Information
Legacy Altera PQFP package uses SnPb lead finish and is not RoHS compliant. AEC-Q100 not applicable for industrial-grade FLEX 6000; no automotive-qualified variant exists. REACH and conflict-mineral declarations not retrievable from the verified web data.
