MPN: EP20K160EQC240-3N ✗ Cuối đờiEP20K160EQC240-3N Tóm tắt
An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) containing configurable logic blocks, programmable interconnect, and I/O cells that engineers can customize after manufacturing. Within the broader semiconductor taxonomy, FPGAs sit under programmable logic -> logic ICs -> integrated circuits. The APEX 20K family specifically pioneered System-on-a-Programmable-Chip (SOPC) integration, combining look-up-table based logic with embedded memory blocks for high-density glue-logic and datapath applications.
Key features include MultiCore architecture combining fine-grain logic with embedded array blocks (EABs) for memory and arithmetic, in-system programmability via IEEE 1149.1 JTAG, multi-voltage I/O supporting 1.8V/2.5V/3.3V interfaces, and LVTTL/LVCMOS/LVDS signaling. The device supports up to 87,040 RAM bits distributed across embedded array blocks, enabling single-chip implementation of FIFOs, dual-port RAM, and DSP-like datapath functions without external memory.
The MultiCore architecture partitions each logic element into a carry-chain for arithmetic plus a register-rich LUT section, allowing efficient mapping of counters, state machines, and datapath pipelines. Built-in JTAG (IEEE 1149.1) boundary-scan and ISR (in-system reconfigurability) let engineers reprogram the device in-circuit, simplifying field upgrades and shortening prototyping cycles. The 0.22 µm CMOS process delivers the speed/power trade-off that made APEX 20K a workhorse for telecom line cards and ASIC prototyping in the early 2000s.
Typical applications include ASIC prototyping, telecommunications line-card glue logic, networking datapath pipelines, and industrial control systems. Designers select this part when they need tens of thousands of gates with embedded block memory, JTAG-based in-system upgrades, and 240-pin PQFP board compatibility.
When designing with the EP20K160EQC240-3N, plan for 1.8V core regulation with bulk decoupling near each VCCINT pin and 3.3V VCCIO rails matched to your logic interface. Use the Quartus II design environment for fitting; place series terminators on clock outputs to limit overshoot, and follow Altera's AN 117 application note for JTAG chain design.

Ghi chú thiết kế
The EP20K160EQC240-3N requires a clean 1.8V core supply (VCCINT) with peak current demand of approximately 1.5A during configuration and high-utilization operation. Use a low-dropout regulator such as the LT1764A-1.8 placed within 25 mm of the VCCINT pins, and pair each VCCINT pin with a 0.1 µF ceramic plus 10 µF tantalum bulk capacitor. VCCIO pins must be tied to 3.3V through a ferrite bead if separate analog and digital 3.3V rails are used. Decoupling placement follows the Altera APEX 20K family reference design in AN 117.
The 240-pin PQFP uses 0.5 mm pitch gull-wing leads; route signals on 0.2 mm trace-and-space rules with power pours on inner layers for VCCINT and VCCIO. Place a continuous ground plane on layer 2 directly under the device to provide a low-impedance return path for the 271 high-speed I/Os. Series termination resistors (33 Ω) on clock outputs and DDR-style interfaces minimize overshoot. JTAG chain signals (TCK, TMS, TDI, TDO) should be length-matched and routed away from switching signals to avoid programming glitches.
Estimated: configuration can fail if nCONFIG is not held low until VCCINT and VCCIO reach 90% of nominal. Avoid driving JTAG pins from external devices during in-system programming - isolate with a buffer to prevent contention. Do not exceed the maximum I/O current of 24 mA per pin or 8 mA for backplane-protected banks. When migrating from -3N to -2N speed grade, expect approximately 25% longer propagation delay and verify timing closure in Quartus II timing analysis before committing to production.
Estimated junction temperature: at full 160K-gate utilization with all 271 I/Os switching simultaneously at 100 MHz, internal dissipation is roughly 1.5W. The 240-pin PQFP has θJA of approximately 25 °C/W in still air on a 4-layer FR-4 board, resulting in a junction-to-ambient rise of about 38 °C above ambient. At 70 °C ambient, the die reaches ~108 °C, well below the 150 °C absolute maximum. Forced-air cooling is not required for typical configurations but is recommended when ambient exceeds 70 °C.
