EPM7256BQC208-7 - 256-Macro MAX 7000B CPLD, 208-PQFP | Intel
MPN: EPM7256BQC208-7 ✗ اختتامِ زندگیEPM7256BQC208-7 جائزہ
A CPLD (Complex Programmable Logic Device) is a non-volatile, flash- or EEPROM-based programmable logic device that sits between discrete 74-series glue logic and larger FPGAs. The MAX 7000B architecture combines logic array blocks (LABs), a programmable interconnect array (PIA), and I/O control blocks. Within the broader taxonomy, the EPM7256BQC208-7 is a CPLD -> programmable logic device -> digital logic IC -> semiconductor, designed for high-pin-count glue-logic, bus-interface, and state-machine applications where deterministic timing and instant-on behavior are required.
Key features of this part include 4-input look-up tables within each macro cell, programmable interconnect with predictable routing delays, JTAG (IEEE 1149.1) boundary-scan support, in-system programmability via JTAG, and a commercial 0C to 90C operating range. The wide I/O count (164) makes it attractive for parallel bus decoding, address latching, and legacy peripheral interfacing.
Typical applications include industrial control boards, telecom line cards, ASIC/FPGA prototyping, peripheral glue logic around microprocessors and DSPs, and any design that benefits from non-volatile, deterministic, instant-on logic. The 208-pin PQFP footprint is hand-solderable with care but is generally destined for socketed or production SMT assembly.

عام استعمالات
EPM7256BQC208-7 کے لیے موزوں ہے 6 ایپلیکیشنs: Industrial Control Glue Logic, Telecom Line-Card Interface, ASIC and FPGA Prototyping, Legacy Peripheral Glue Logic, Automotive Infotainment Bus Bridge, Test and Measurement Instrumentation.
Industrial Control Glue Logic
The EPM7256BQC208-7 is widely used in industrial PLCs and motor-control boards where 164 user I/Os and deterministic 7.5 ns tPD propagation delay let designers replace dozens of 74-series glue-logic chips with one programmable device. The non-volatile EEPROM configuration retains state through brown-outs and power cycling, which is critical for industrial equipment that must resume operation without re-flashing. The 2.5 V core with 5 V-tolerant I/O banks (via VCCIO) allows direct interfacing with legacy 5 V peripherals, optocouplers, and 24 V industrial sensors. Engineers value the JTAG in-system programmability for firmware updates on deployed equipment.

Telecom Line-Card Interface
Telecom line cards frequently use the EPM7256BQC208-7 to perform bus arbitration, address decoding, and protocol translation between network processors and TDM/Ethernet framer ASICs. The 126.6 MHz internal frequency supports high-speed glue functions between Fast Ethernet PHYs, T1/E1 framers, and backplane buses. The deterministic timing of CPLD logic (versus FPGA soft cores) simplifies timing closure for telecom applications where jitter budgets are tight. The 208-pin PQFP package is large enough to break out 164 I/Os into multiple parallel data buses without requiring additional bus transceivers.
تجویز کردہ
ASIC and FPGA Prototyping
Designers prototyping ASICs or validating FPGA-based designs use the EPM7256BQC208-7 as a hardware emulator for glue logic that will eventually be absorbed into an ASIC. The 256 macro cells and 5,000 usable gates are sufficient to model medium-complexity state machines, FIFO controllers, and custom bus protocols. The non-volatile EEPROM lets prototype boards boot immediately without external boot PROMs, accelerating bring-up and bench testing. Quartus II design entry with schematic capture and Verilog/VHDL synthesis reduces design iteration time versus discrete TTL prototypes.

Legacy Peripheral Glue Logic
The EPM7256BQC208-7 replaces 74HC/74FCT glue logic around microprocessors, DSPs, and memory interfaces. Typical uses include address decoding, chip-select generation, wait-state insertion, and interrupt prioritization. The 164 I/Os accommodate parallel SRAM, NOR flash, and peripheral interfaces simultaneously, eliminating the need for separate address-latch and decoder chips. Programmable pin assignments simplify PCB routing when designers need to swap signals between board revisions without re-spinning the layout.

Automotive Infotainment Bus Bridge
In automotive infotainment systems the EPM7256BQC208-7 bridges between I2S audio buses, SPI peripherals, and CAN/LIN network segments. The MAX 7000B architecture supports 5 V-tolerant I/O banks for direct connection to legacy automotive microcontrollers and CAN transceivers. The 7.5 ns tPD keeps audio sample-rate jitter well below audible thresholds. Designers value the JTAG interface for end-of-line programming in automotive manufacturing.
تجویز کردہ
Test and Measurement Instrumentation
Test equipment such as logic analyzers, oscilloscope front-ends, and protocol exercisers use the EPM7256BQC208-7 to perform pattern generation, channel multiplexing, and trigger logic. The deterministic 7.5 ns propagation delay supports precise timing-critical trigger generation, while the 164 I/Os allow parallel pattern output across 32+ channels with margin for address and control signals. The PQFP package is large enough to expose all I/Os on a daughter-card for ribbon-cable connection to a backplane test fixture.

ڈیزائن نوٹس
Estimated: at typical 50 MHz toggle activity across 100 of 164 I/Os with 5 V VCCIO, dynamic current is approximately 50-80 mA from VCCIO plus 30-50 mA from VCCINT (2.5 V). Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, and add a 10 uF bulk capacitor per supply rail near the package. PQFP packages do not have an exposed thermal pad; use a ground pour under the device to spread heat and lower loop inductance on switching outputs.
Route JTAG signals (TDI, TDO, TMS, TCK) in a daisy-chain topology with 10K pull-ups on TMS and TCK per IEEE 1149.1. Keep JTAG traces short (<= 50 mm) and guarded by GND to avoid noise-induced programming failures. Place a 4.7K pull-up on DEV_CLRn and DEV_OE to default the device to user mode after configuration, or pull DEV_OE low to tri-state all I/Os during in-system programming.
Do not confuse the EPM7256BQC208-7 (MAX 7000B, 2.5 V core) with the EPM7256AQC208-7 (MAX 7000A, 3.3 V core). They share the same PQFP-208 footprint but require different VCCINT rails; substituting one for the other without re-routing power will damage the device. Also note that Quartus II versions earlier than 13.0 SP1 may not support the latest MAX 7000B programming algorithms - use Quartus II 13.0 SP1 or later for reliable programming file generation.
PQFP-208 leads have approximately 1.5 nH of lead inductance each, which can cause ringing on high-speed outputs above 50 MHz. For clock-like signals above 50 MHz, source-terminate with a 33-ohm series resistor to dampen reflections, and keep trace stubs < 5 mm. Place a 50-ohm characteristic-impedance reference for controlled-impedance signals routed off-device.
