Typical Applications
EPM7160EQC160-12 is suitable for 6 applications: 5V ISA Bus Interface & Glue Logic, Industrial Control & PLC Logic, Peripheral Controller & Legacy Port Emulation, Telecom Backplane Glue Logic, Legacy Miltary/Aerospace Replacement Board, Memory Controller & Bus Arbiter.
5V ISA Bus Interface & Glue Logic
The EPM7160EQC160-12 is ideally suited to legacy 5V ISA and VME bus interface designs, where it consolidates address decoding, interrupt steering, and wait-state generation that previously required multiple 74LS/74F TTL packages. Its 5.0V VCCINT/VCCIO and 104 user I/O pins comfortably handle the full 16-bit ISA address bus plus control signals, while the 12 ns pin-to-pin delay provides deterministic timing for cycle completion. The 160 macrocells can implement multiple state machines, bus arbitrators, and custom peripheral decoders in a single non-volatile device, replacing 4-6 discrete logic packages and reducing PCB area. Compared to an FPGA, the EEPROM-based MAX 7000E family offers instant-on configuration with no external boot memory, which is critical for ISA cards that must be ready immediately after power-up.
Recommended
Industrial Control & PLC Logic
In industrial PLC and process-control designs, the EPM7160EQC160-12 replaces racks of discrete CMOS logic with a single reprogrammable device, enabling late-stage design changes via JTAG without board rework. Its 0Β°C to +70Β°C commercial temperature range covers most factory-floor enclosures, and the 3,200 usable gates are sufficient for stepper-motor controllers, encoder interfaces, and multi-axis timing logic. The on-chip EEPROM configuration means the PLC retains its logic across power cycles without an external boot PROM - a major reliability advantage over SRAM-based FPGAs. The 104 I/O pins also allow direct interfacing to 24V-to-5V opto-isolated field wiring without intermediate buffers, simplifying the BOM.
Recommended
Peripheral Controller & Legacy Port Emulation
The EPM7160EQC160-12 is widely deployed as a peripheral controller implementing parallel ports, SCSI termination, and custom DMA engines in industrial and test equipment. Its 4 global clocks and 4 output-enable controls enable complex bus-arbitration schemes, while the 160 macrocells can host multiple parallel state machines for command decoding and data routing. The device is fully reprogrammable in-system via JTAG, allowing firmware updates over production life. Compared to discrete 74-series logic, the CPLD reduces chip count by 5-10x and eliminates timing-skew problems between parallel logic paths.
Recommended
Telecom Backplane Glue Logic
In telecom backplane applications, the EPM7160EQC160-12 implements bus repeaters, signal-conditioning logic, and protocol-bridge functions between legacy TDM buses and modern packet interfaces. Its 5V tolerant I/O and JTAG ISP support simplify in-service reprogramming during network upgrades. The 12 ns pin-to-pin delay is fast enough for 50 MHz backplane operation, while 104 I/O pins support wide parallel data paths. The non-volatile configuration ensures the device is operational within microseconds of power-up - critical for hot-standby redundancy in carrier-grade systems.
Recommended
Legacy Miltary/Aerospace Replacement Board
The EPM7160EQC160-12 is commonly specified as a form-fit-function replacement for obsolete discrete-logic boards in legacy military and aerospace systems. Its PQFP-160 package and 5V operation match the original through-hole and SOIC designs being modernized, while the JTAG ISP allows in-system logic updates during depot-level maintenance. The 160 macrocells and 104 I/O pins can replace entire 16-IC TTL boards, reducing weight and power consumption. Designers must verify industrial (EPM7160EQI160-12) or military temperature grade availability for harsh-environment deployment.
Recommended
Memory Controller & Bus Arbiter
The EPM7160EQC160-12 is frequently used as a DRAM/SDRAM controller or multi-master bus arbiter in 5V embedded systems. Its 4 global clocks support synchronous DRAM timing requirements, while the 160 macrocells can implement refresh counters, address multiplexing, and chip-select decoding in a single device. The 12 ns pin-to-pin delay enables row-address access times suitable for 50-66 MHz memory buses, and the deterministic timing simplifies worst-case timing closure. Compared to an ASIC, the CPLD allows rapid prototyping and design iteration during early product development.

Key Differentiators
- Highest I/O count in commercial-temp MAX 7000E family (vs EPM7128EQC100-10)
- 12 ns speed grade is the mainstream balance point (vs EPM7160EQC160-15)
- Non-volatile EEPROM configuration (vs SRAM-based FPGAs)
- 5V native I/O support (vs 3.3V MAX II / MAX V CPLDs)
Design Notes
The EPM7160EQC160-12 requires a stable 5.0V Β±5% supply on all VCC pins with decoupling: place one 0.1 Β΅F ceramic capacitor adjacent to each VCC/GND pair (typically 4-8 caps depending on pin assignment), plus a single 10 Β΅F tantalum or ceramic bulk capacitor near the package. Estimated ICC during normal operation is approximately 200-300 mA; in-circuit programming may increase this briefly. Avoid sharing the CPLD's VCC plane with high-current switching regulators to prevent logic-level noise on supply rails.
The PQFP-160 package has a 0.65 mm pitch and a 31 mm body length, requiring careful PCB layout. Use a 4-layer board with a dedicated ground plane to control EMI and provide low-impedance return paths for the high-edge-rate I/O signals. Keep all JTAG signals (TDI, TMS, TCK, TDO) within 25 mm of the device and route TCK with a 22-33 Ξ© series damping resistor if the trace exceeds 50 mm. Leave at least 3 mm of clearance around the PQFP-160 for probe-tip access during in-system debugging.
Do not assume the EPM7160EQC160-12 is 3.3 V tolerant - the I/O and core supplies are both 5.0 V, and applying 3.3 V signals directly without level shifting may cause reliability issues. The JTAG ISP chain must be terminated correctly: tie TMS and TDI high through 10 kΞ© pull-ups if no programmer is connected, otherwise floating inputs can latch the TAP controller into an unintended state. The MAX 7000E family does not support live in-system reconfiguration during user-mode operation - the device enters ISP mode and user I/O is tri-stated during programming. Do not mix JTAG and non-JTAG devices in the same chain without understanding the BYPASS register length of each device.
Estimated: at maximum toggle rate (all 104 I/O switching at 10 MHz with 50 pF loads), the EPM7160EQC160-12 dissipates approximately 1.5-2.0 W. The PQFP-160 package has a thermal resistance (ΞΈJA) of approximately 35 Β°C/W for a 4-layer JEDEC test board, yielding a junction temperature rise of 50-70 Β°C above ambient. For high-altitude or sealed-enclosure applications, derate clock frequency or reduce simultaneously-switching output (SSO) count to keep junction temperature below 125 Β°C. The commercial-grade device is rated to 70 Β°C ambient; for industrial or extended-temperature deployment, use the EPM7160EQI160-12 variant.
Compliance Information
RoHS and REACH status were not present in the verified web data; consult the Intel product page or distributor for current compliance certificates. The MAX 7000E family was introduced before AEC-Q100 qualification became standard for automotive CPLDs, so no AEC-Q100 variant is available - for automotive applications consider the MAX V or Cyclone families.
