EP20K200CQ240C7 Overview
An FPGA is an integrated circuit containing programmable logic blocks and programmable interconnect. An engineer configures the device after manufacturing using a hardware description language such as VHDL or Verilog. Unlike a fixed ASIC, the EP20K200CQ240C7 can implement different functions during development or at run time when paired with configuration memory. In a signal-chain hierarchy, an FPGA often sits between data converters and processors, handling parallel data movement, protocol timing, and custom DSP arithmetic.
The main verified specifications are 8,320 logic elements, giving a 200K-class APEX-20K density level; 106,496 RAM bits for FIFOs, packet buffers, and dual-port memory functions; and 168 user I/Os for wide parallel buses and external control. The device is supplied in a 240-pin BFQFP, a surface-mount plastic quad flat pack footprint used by many legacy industrial and communication boards.
Distributor data consistently identifies the part as an APEX-20KC product, with the CQ240C7 suffix indicating the package and Altera-grade ordering code. The device is now often obtained through specialty aftermarket channels, and engineers should verify current lifecycle and configuration compatibility before new designs or repair programs.
Typical applications include networking protocol bridging, telecom baseband interfaces, industrial control I/O logic, test-and-measurement pattern generation, and legacy system lifecycle extension. The FPGA is especially useful where 168 I/Os must connect to ADCs, DACs, memory buses, and processors in parallel rather than through high-speed serial links.
When designing with a legacy FPGA, confirm exact core and I/O supply voltages, pin numbering, and configuration scheme from the APEX-20K family datasheet before PCB layout. Since the part has been in service for many years, verify lead-free finish requirements because non-N suffix devices may not be RoHS-compliant.

Typical Applications
EP20K200CQ240C7 is suitable for 6 applications: Networking and Protocol Bridging, Industrial Motion Control and PLC I/O, Digital Signal Processing and Data Acquisition, Test and Measurement Instrumentation, Telecom Baseband and Line Card Logic, Aerospace and Defense Legacy Upgrade.
Networking and Protocol Bridging
The EP20K200CQ240C7 suits network bridging, switch fabric, and protocol adaptation boards that require 168 parallel I/Os and 106,496 bits of on-chip packet buffer RAM. Its 8,320 logic elements can implement Ethernet MAC state machines, FIFO management, and custom scheduling logic without external glue. In a typical line-card design, the FPGA sits between PHYs and an application processor, translating parallel bus timings and segmenting data into packet descriptors. The 240-pin BFQFP keeps routing manageable for wide parallel data and control buses. If a system is already designed around the APEX-20KC pinout, this device remains a practical choice for legacy maintenance and moderate-bandwidth networking applications.
Recommended
Industrial Motion Control and PLC I/O
The EP20K200CQ240C7 is well matched to industrial controllers that need dedicated parallel I/O for encoders, limit switches, ADC/DAC interfaces, and fieldbus controllers. Its 168 user I/Os allow direct connection to motor-driver control buses and optocoupler arrays without a large CPLD farm. The 8,320 logic elements can implement multiple PID loops, step-direction pulse generators, and interlock logic. On-board RAM supports small FIFOs for sensor data and motion profiles. For enclosed PLCs in 0-70C environments, the commercial C grade is often adequate; if the panel is exposed to wider temperature swings, choose the I-grade variant on the same footprint.
Recommended
Digital Signal Processing and Data Acquisition
The EP20K200CQ240C7 is suitable for moderate-speed DSP and data-acquisition front ends. Its 8,320 logic elements can implement FIR filters, correlators, digital up/down converters, and custom data-format conversion logic. The 106,496 RAM bits provide useful storage for filter coefficient tables, circular buffers, and dual-port FIFO buffers between ADC, DSP, and host processors. With 168 I/Os, the FPGA can directly capture parallel ADCs, drive DACs, and interface to SRAM or SDRAM buses. Although newer FPGAs include hardened DSP blocks and high-speed serial I/O, this APEX-20KC device works well in legacy systems with a parallel, moderate-clock signal chain.
Recommended
Test and Measurement Instrumentation
The EP20K200CQ240C7 can serve as the pattern generator, logic analyzer interface, or digital control core of bench instruments such as oscilloscopes, arbitrary waveform generators, and data loggers. Its 168 I/Os connect directly to acquisition ADC buses, DAC output registers, trigger comparators, and front-panel control logic. The embedded 106,496 RAM bits are useful for acquisition buffers and sequencing patterns, while the 8,320 logic elements implement trigger state machines and measurement algorithms. Test instruments often require reliable delivery for many years; this legacy FPGA is a common target for instrument repair and life-extension programs where the original PCB must be retained.
Recommended
Telecom Baseband and Line Card Logic
The EP20K200CQ240C7 is suitable for telecom line cards and baseband boards implementing channel mapping, HDLC processing, or parallel TDM buses. The combination of 8,320 logic elements and 106,496 RAM bits allows designers to build small cell buffers, HDLC controllers, and clock-domain-crossing FIFOs on a single FPGA, saving board area and reducing component count. With 168 user I/Os, the device can bridge parallel backplane buses, DSP devices, and framers. Although modern telecom designs use faster serial protocols, the APEX-20KC remains important for installed-base upgrades and maintenance of existing wireless and wireline infrastructure.
Recommended
Aerospace and Defense Legacy Upgrade
Military and aerospace systems often use qualified legacy FPGAs for maintenance and repair because requalifying a new board is expensive. The EP20K200CQ240C7, with 8,320 logic elements, 106,496 RAM bits, and 168 I/Os, can be a direct FPGA for existing APEX-20KC circuit cards. It is important to verify that the exact device variant, temperature grade, package finish, and screening meet the original design. For ruggedized platforms requiring a wider industrial temperature range, select the I-suffix variant such as EP20K200CQ240I7. This page assists in locating pricing and functional alternatives without requiring an immediate system redesign.

Design Notes
The EP20K200CQ240C7 core and I/O supply voltages are not stated in the distributor snippets used for this page, so obtain the APEX-20KC DC specifications from the manufacturer family datasheet before design. Plan separate power planes for core and I/O supplies, place a 0.1 uF ceramic capacitor near every supply pin, and add 10 uF bulk capacitance per rail. Use the datasheet power-up current and maximum supply current values to size the DC-DC converters. Avoid sharing sensitive configuration supply pins with high-noise digital outputs.
The 240-pin BFQFP is a plastic quad flat pack with leads on four sides; heat is conducted primarily through the package leads and the surrounding copper plane. If the EP20K200CQ240C7 is used near its maximum logic utilization and I/O toggle rate, increase the ground/power copper area around the package and remove solder mask from the traces connected to the lead frame where possible. Junction temperature should be estimated from the datasheet thermal resistance, ambient temperature, and estimated power dissipation. For this legacy part, verify the thermal resistance value from the official datasheet because it is not included in the verified web search snippets.
Route the 240-pin BFQFP with a solid ground reference beneath the device. Keep high-speed clock and data traces length-matched, especially for wide parallel buses between the FPGA and memory or ADC/DAC devices. Use series termination resistors close to the FPGA outputs when driving long traces to reduce ringing. For JTAG and configuration signals, add pull-up resistors and route them away from switching power traces. If this is a legacy replacement board, compare the original layout's via pattern with the APEX-20K recommended footprint to avoid thermal or routability issues.
Do not assume that a non-N EP20K200CQ240C7 is RoHS-compliant; verify finish and compliance before assembly. Also do not mix C7 and C8 or C9 speed-grade devices without rerunning static timing, because the configuration may be logically compatible but timing margins will differ. Since the device is legacy, confirm programming voltage and configuration device compatibility; using the wrong configuration-file format can fail silently. Finally, check pin 1 orientation on the 240-pin QFP against the actual PCB footprint before first board bring-up.
Compliance Information
Verified distributor search results do not provide RoHS/REACH or lead-free statements for EP20K200CQ240C7. The N suffix in Altera legacy ordering often denotes lead-free finish, but this must be confirmed from the manufacturer datasheet or a certificate of compliance.
