EPM7160SQC160-10 Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like logic blocks with a programmable interconnect matrix, sitting in the broader taxonomy of programmable logic -> logic devices -> digital ICs -> semiconductors. CPLDs are valued for deterministic pin-to-pin propagation delay (typically 5-10 ns), instant-on configuration from non-volatile EEPROM, and the ability to replace dozens of discrete 74-series glue-logic chips on a board.
Key features of the EPM7160SQC160-10 include 160 macro cells organized in 10 Logic Array Blocks (LABs), a 100 MHz internal operating frequency, 6 ns pin-to-pin propagation delay (tPD), and 5.0V in-system programmability through the IEEE 1149.1 (JTAG) boundary-scan interface. The 104 user I/Os support 5V tolerant inputs with 3.3V or 5V output options, and the device offers programmable power-saving modes that reduce standby current.
The MAX 7000S architecture uses an EEPROM cell array that holds configuration even when power is removed, eliminating the need for external boot PROMs. Each macro cell contains a programmable AND/OR array and a configurable flip-flop, allowing designers to implement both combinatorial and registered logic at deterministic timing. The interconnect is a continuous, fast path between LABs, with predictable propagation delay that simplifies static-timing closure.
Typical applications include bus-interface glue logic for microprocessor and DSP systems, peripheral controllers in industrial automation, state-machine implementation in legacy 5V designs, and address decoding for memory subsystems. The wide 5V I/O tolerance makes the part especially useful as a bridge between modern 3.3V controllers and legacy 5V peripherals.
When designing with this device, observe that propagation delay is specified at 10 ns (the "-10" speed grade) and that supply voltage is 5V; substituting it into a 3.3V-only board will not function. The JTAG chain must be designed to allow ISP re-programming without removing the part from the board, and unused I/O pins should be left floating or terminated per the datasheet to minimize quiescent current.

Typical Applications
EPM7160SQC160-10 is suitable for 6 applications: Microprocessor / DSP Bus Glue Logic, Industrial Automation Peripheral Controllers, Legacy 5V System Address Decoding, State Machine and Protocol Conversion, Telecommunications Backplane Glue Logic, Test & Measurement Front-End Control.
Microprocessor / DSP Bus Glue Logic
The EPM7160SQC160-10 fits microprocessor and DSP bus-glue applications because its 160 macro cells can implement dozens of address decoders, chip-select generators, and wait-state controllers in a single 5V part. With 104 user I/Os and a deterministic 10 ns pin-to-pin propagation delay, the device reliably latches address and control lines between a host CPU and external peripherals without metastability risk. Its 5V-tolerant I/O bridges cleanly between 3.3V modern controllers and legacy 5V peripherals, eliminating the need for external level shifters. JTAG-based ISP allows field firmware updates without desoldering, and the EEPROM-based configuration boots instantly without an external PROM.
Recommended
Industrial Automation Peripheral Controllers
In industrial automation, the EPM7160SQC160-10 is commonly deployed as a peripheral controller implementing custom I/O expansion, encoder interfaces, and real-time state machines alongside a PLC or microcontroller. Its 100 MHz internal frequency and 10 ns tPD handle 100 kHz to 1 MHz industrial protocols (Modbus RTU over RS-485, parallel encoder feedback) with substantial timing margin. The 104 user I/Os allow direct connection to many optocouplers, relays, and 24V-tolerant input buffers commonly found on industrial backplanes. Because the part runs at 5V and supports commercial 0 to +70 C operation, it fits inside sealed control cabinets where ambient temperatures remain moderate.
Recommended
Legacy 5V System Address Decoding
The EPM7160SQC160-10 is ideal for memory address decoding in legacy 5V systems because its 104 I/Os can drive up to 104 chip-select or address-line signals from a single device, replacing dozens of discrete 74LS138 / 74HC138 decoder ICs. Its deterministic 10 ns tPD adds minimal latency to memory access cycles, while the EEPROM-based configuration retains decoding logic across power cycles without boot time. The 5V native I/O interfaces directly to 5V SRAM, EPROM, and peripheral chips common in 1990s-2000s embedded designs. For designers maintaining installed industrial or military equipment, this part remains a cost-effective spare-parts source versus full board redesign.
Recommended
State Machine and Protocol Conversion
The 160 macro cells in the EPM7160SQC160-10 comfortably implement complex FSMs and protocol converters (e.g., UART-to-SPI bridges, parallel-to-I2C adapters, custom motor-control sequencers) at deterministic timing. With 10 LABs each containing 16 macro cells, designers can partition state machines cleanly across LAB boundaries to simplify timing closure and future code maintenance. The 100 MHz fMAX ensures that even multi-state encoders operating at 10-20 MHz of throughput have substantial timing margin. JTAG-based in-system programmability allows field upgrades when protocol revisions are needed, which is critical for deployed industrial systems.
Recommended
Telecommunications Backplane Glue Logic
Telecommunications backplanes in legacy central-office equipment often use the EPM7160SQC160-10 to implement TDM bus arbiters, framing controllers, and clock-distribution glue logic between line cards. The 104 I/Os handle multi-drop bus connections to many line cards simultaneously, and the 10 ns tPD supports E1/T1 (2.048 / 1.544 MHz) and higher-speed PCM highway timing with substantial margin. The 5V supply matches legacy telecom -48V-to-5V DC-DC converter rails without level shifting. Its commercial 0 to +70 C range is acceptable for climate-controlled central-office environments.
Recommended
Test & Measurement Front-End Control
Test and measurement instruments (oscilloscopes, logic analyzers, bench-top data loggers) historically use the EPM7160SQC160-10 to sequence front-end relays, attenuators, and ADC/DAC multiplexers. The deterministic timing ensures that channel-switching events occur at precise sample-clock boundaries, avoiding glitches in measurement data. The 104 I/Os are sufficient to control 16-32 channel multiplexer banks plus status LEDs, range-select relays, and trigger logic. The JTAG interface allows factory calibration updates without opening the instrument enclosure, simplifying manufacturing test workflows.

Design Notes
The EPM7160SQC160-10 requires a tightly regulated 5.0 V +/- 5% supply on VCCINT (typically pin numbers distributed across the PQFP-160 package); using a 3.3V rail will prevent configuration and may damage the EEPROM cells. Decoupling: place one 0.1 uF ceramic cap adjacent to each VCC pin and a bulk 10-47 uF tantalum or aluminum polymer cap within 1 cm of the package. For ISP programming, ensure the VCC rail can supply peak inrush current during configuration of approximately 200-300 mA without sagging below 4.75 V. Estimated Icc standby is 10-25 mA and active current scales with fMAX and toggle rate; unused LABs can be powered down via the Quartus / MAX+PLUS II power-management settings to reduce quiescent draw.
PQFP-160 has a 0.65 mm pitch and 3.2 mm wide body; use a 4-layer PCB with continuous VCC and GND planes directly under the package to provide low-impedance power delivery and thermal spreading. Place the JTAG header (TDI, TDO, TMS, TCK, GND, VCC) within 5 cm of the part to allow ISP programming in production without long flying leads. Route all clock inputs on the inner layers with controlled impedance and length-matched to within 100 mils to avoid skew across LABs. Exposed lead frames on PQFP packages can be soldered to perimeter pads; follow IPC-7351 land-pattern guidelines for the 160-pin QFP footprint. Avoid routing signal traces beneath the package body to prevent noise coupling into the high-impedance programming logic.
Common pitfalls when designing with the EPM7160SQC160-10: (1) Mistaking the -10 speed grade for -7 or -6 - the -10 has a 10 ns tPD and 100 MHz fMAX, which is insufficient for 133 MHz synchronous memory buses. (2) Forgetting that all VCC pins must be connected even if their associated I/O banks are unused - floating VCC pins cause EEPROM programming failures. (3) Driving 5V outputs into 3.3V-only peripherals without confirming Voh compatibility, since the EPM7160SQC160-10 outputs TTL-level signals at 5V. (4) Using JTAG pins as user I/Os during prototyping - the JTAG interface must remain accessible for in-system programming, or an external programmer will be required. (5) Substituting a non-N part into a RoHS-compliant assembly - the standard EPM7160SQC160-10 has tin-lead solder finish and will fail reflow at 245 C; choose EPM7160SQC160-10N instead.
PQFP-160 has a thermal resistance theta-JA of approximately 35-45 C/W on a 4-layer JEDEC test board, depending on copper-pour coverage and airflow. The EPM7160SQC160-10 typically dissipates 0.5-1.5 W during normal operation; with 1 W dissipation the junction temperature rises roughly 40 C above ambient. For sealed industrial enclosures or extended-temperature applications, add thermal vias under the package center pad region and use 2 oz copper pours on outer layers to reduce theta-JA. The commercial 0 to +70 C operating range assumes ambient air within specifications; derating is not required below 70 C. For new designs above 70 C ambient, consider the industrial MAX 7000A or MAX II variants which offer -40 to +85 C support.
Compliance Information
Standard EPM7160SQC160-10 is non-RoHS (tin-lead finish); use EPM7160SQC160-10N for RoHS compliance. Compliance data for RoHS variants is derived from datasheet ordering information; detailed REACH / halogen-free / conflict-minerals declarations are not publicly listed and marked unknown.
