EPM7160EQC160-12 Übersicht
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays on a single chip with a global interconnect matrix. CPLDs sit in the programmable logic hierarchy between small SPLDs (typically a few macrocells) and large FPGAs, offering deterministic timing, instant-on operation from on-chip EEPROM, and high fan-in / fan-out capability. They are widely used as glue logic, bus interface bridges, and state-machine controllers in industrial, telecom, and automotive systems.
The EPM7160EQC160-12 delivers 3,200 usable gates, four global clock signals with additional output enable controls, fast input registers, and an enhanced interconnect fabric that improves routability versus the original MAX 7000S family. Its 5 V tolerant I/O and commercial 0 °C to +70 °C operating range make it well suited to legacy 5 V system designs. The device is non-volatile - configuration is retained without external memory and is reprogrammable in-circuit through JTAG.
The MAX 7000E architecture pairs each macrocell with a product-term array that feeds into a programmable register, with each LAB (Logic Array Block) sharing 36 macrocells and an I/O block of 36 signals. This balanced architecture yields predictable, fixed propagation delays that are critical for address decoding, interrupt steering, and synchronous state machines where FPGAs would be over-specified.
Typical applications include 5 V bus interfacing (ISA, VME, parallel port), industrial control glue logic, peripheral controllers, and drop-in upgrades for older discrete TTL/CMOS logic. Designers favor the EPM7160EQC160-12 when they need a non-volatile, JTAG-reprogrammable logic block with deterministic timing and a PQFP-160 footprint compatible with long-lived industrial designs.
A key design tip: the PQFP-160 package has relatively high thermal resistance - keep switching frequencies moderate and observe the 5 V VCCIO decoupling guidelines (0.1 µF + 10 µF bulk per VCC pin pair). The JTAG TCK maximum frequency of 10 MHz governs ISP programming time; budget approximately 2-5 seconds for full device erase-and-program.

Typische Anwendungen
EPM7160EQC160-12 ist geeignet für 6 Anwendungs: 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.
Empfohlen
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 0°C to +70°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.
Empfohlen
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.
Empfohlen
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.

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.
Empfohlen
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.

Wichtigste Unterscheidungsmerkmale
- 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)
Designhinweise
The EPM7160EQC160-12 requires a stable 5.0V ±5% supply on all VCC pins with decoupling: place one 0.1 µF ceramic capacitor adjacent to each VCC/GND pair (typically 4-8 caps depending on pin assignment), plus a single 10 µF 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 Ω 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 kΩ 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 (θJA) of approximately 35 °C/W for a 4-layer JEDEC test board, yielding a junction temperature rise of 50-70 °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 °C. The commercial-grade device is rated to 70 °C ambient; for industrial or extended-temperature deployment, use the EPM7160EQI160-12 variant.
Compliance-Informationen
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.
