EPM7160EQC100-20 Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits in the broader hierarchy of programmable logic: it is a sibling of the simpler SPLD and an ancestor of the modern FPGA and CPLD sub-classes. The MAX 7000 family targets glue-logic, bus-interface, control-plane, and high-drive applications where deterministic timing and instant-on non-volatile configuration are required. Designers use MAX 7000 parts for decoding, address mapping, state-machine implementation, and bus arbitration in systems where an FPGA would be overkill or where fast, predictable propagation delay is essential.
Key features of the EPM7160EQC100-20 include configurable 3.3 V or 5 V I/O operation (5 V nominal core supply), an Enhanced Quad Flat Pack (EQFP) form factor, and commercial temperature-grade operation. The 'E' suffix indicates an enhanced configuration mode for fast in-system programming, while 'QC100' denotes the 100-pin PQFP package, and '-20' specifies the 20 ns speed grade. The CPLD supports the IEEE 1149.1 boundary-scan (JTAG) interface and uses 4-pin JTAG ISP for in-system programming. According to the Altera MAX 7000 datasheet, the device can be erased and reprogrammed in-system up to 100 times, and configuration is non-volatile via on-chip EEPROM.
The MAX architecture uses a classic Logic Array Block (LAB) / Programmable Interconnect Array (PIA) topology, where each macrocell is fed by a 36-input AND-style product term array and registered feedback. The macrocell contains a programmable flip-flop with selectable clear, preset, clock, and clock-enable signals, supporting D, T, JK, and SR flip-flop operation. The macrocell can also be configured for combinational logic when registers are not required, allowing the designer to allocate logic and register resources where they are needed most.
Typical applications include peripheral interface bridging (e.g., connecting a microcontroller to legacy parallel ports), bus decode and chip-select generation for microprocessors, asynchronous state-machine controllers, and high-drive bus-buffer or level-translation between 3.3 V and 5 V domains. Designers also deploy the EPM7160EQC100-20 in industrial control systems, telecom glue logic, and retrofit boards that must match a legacy 100-pin PQFP footprint. The 84 available I/Os are sufficient for medium-complexity glue-logic, and the 5 V-tolerant I/Os ease mixed-voltage interfacing.
When designing with this device, allow at least 1 ms after power-up before JTAG programming and provide a clean 5 V supply with 100 nF + 10 uF decoupling close to the VCC pins. The PQFP-100 footprint requires careful soldering or socket use; engineers evaluating modern replacements should consider MAX II or MAX V devices in smaller QFP or BGA packages for new designs.

Typical Applications
EPM7160EQC100-20 is suitable for 6 applications: Address Decode and Chip-Select Generation, Microcontroller Bus Glue Logic, Mixed-Voltage Level Translation and Bus Buffering, Industrial Control State Machines, Peripheral Interface Bridging (UART/SPI/I2C Glue), Legacy Industrial Retrofit Boards.
Address Decode and Chip-Select Generation
The EPM7160EQC100-20's 20 ns pin-to-pin delay and 160 macrocells make it a strong fit for address-decode and chip-select generation in 8/16/32-bit microprocessor systems. Its deterministic timing allows decode logic to be inserted in a single logic level without affecting the processor's address-to-access timing budget. The 5 V-tolerant I/O and 84 user I/Os comfortably cover memory bank selects, peripheral strobes, and wait-state generation across multiple address ranges, and the JTAG interface simplifies in-system updates as memory maps evolve during product revisions.
Recommended
Microcontroller Bus Glue Logic
Microcontroller and DSP systems often need bus arbitration, peripheral multiplexing, address/data demultiplexing, and protocol bridging that does not justify an FPGA. The EPM7160EQC100-20's 160 macrocells comfortably absorb these glue-logic functions while its 20 ns tPD adds negligible latency to the bus cycle. With 84 I/Os, the part can simultaneously manage multiple peripherals, and its 5 V I/O tolerance allows direct connection to legacy 5 V microcontrollers such as 8051, HC11, and PIC18 families without external level shifters.
Recommended
Mixed-Voltage Level Translation and Bus Buffering
Boards that bridge 5 V and 3.3 V domains benefit from the EPM7160EQC100-20's configurable I/O voltage support, which allows each I/O bank to operate at 3.3 V or 5 V independently. Designers can use the part as a bidirectional voltage translator, address isolator, or bus repeater between legacy 5 V peripherals and modern 3.3 V ASICs. With 84 I/Os and 160 macrocells, a single EPM7160EQC100-20 can replace several discrete 74LVC/74HCT buffers and translators, simplifying the BOM and improving signal integrity through matched-impedance outputs.
Recommended
Industrial Control State Machines
Industrial controllers require deterministic state machines for sequencing, alarm handling, and fail-safe interlocking. The EPM7160EQC100-20's 160 macrocells support many concurrent Moore/Mealy state machines with rich encoding, and the 20 ns propagation delay ensures that input changes are translated to safe outputs within a single scan cycle. The 0 Β°C to +90 Β°C commercial operating range suits factory-floor enclosures with active cooling, and the non-volatile instant-on configuration means the controller resumes operation in microseconds after a brown-out or cold start.
Recommended
Peripheral Interface Bridging (UART/SPI/I2C Glue)
System designers frequently use the EPM7160EQC100-20 to bridge incompatible peripheral protocols, convert parallel buses to serial, and add interrupt-aggregation or DMA-engine logic. Its 160 macrocells accommodate state-rich protocol converters and FIFO pointers, while the 84 I/Os handle full parallel databuses plus multiple serial channels. The instant-on non-volatile configuration allows the bridge to be active before the host CPU boots, simplifying firmware bring-up and enabling ROM-less designs.
Recommended
Legacy Industrial Retrofit Boards
Many factory-floor systems designed in the 1990s and 2000s use MAX 7000 CPLDs and require spare/replacement parts for board repair. The EPM7160EQC100-20 is a direct replacement for damaged or aged devices on these legacy boards because it preserves the 100-pin PQFP footprint, the 5 V supply envelope, and the 4-pin JTAG programming flow. The instant-on non-volatile EEPROM configuration lets repaired boards resume operation immediately on power-up, eliminating the in-system-programming step that would otherwise delay commissioning.

Key Differentiators
- Higher macrocell density than the EPM7128EQC100-20 in the same 100-pin PQFP (vs EPM7128EQC100-20)
- 5 V native core supply, unlike modern MAX II/MAX V CPLDs (vs MAX II EPM240T100C5N)
- Non-volatile, instant-on EEPROM configuration (vs SRAM-based FPGAs (e.g., Cyclone series))
- Slower speed grade (-20) is lower cost for non-timing-critical designs (vs EPM7160EQC100-15)
Design Notes
The EPM7160EQC100-20 requires a clean 5 V (4.75 V to 5.25 V) supply on VCCINT with at least 100 nF and 10 uF decoupling placed within 5 mm of the VCC pins. The I/O banks can be configured independently for 3.3 V or 5 V operation; if mixing, route separate VCCIO planes and decouple each bank individually. Bulk capacitance of 47 uF to 100 uF on the main 5 V rail is recommended to absorb switching transients during JTAG programming or simultaneous I/O toggling.
The 100-pin PQFP (EQFP) has a 0.65 mm terminal pitch and a body size of roughly 14 x 20 mm, so PCB land patterns should follow IPC-7351 PQFP-100 with 3 mm clearances around the package for reworking. Route signal traces on inner layers to escape the dense outer pin pitch and place a continuous ground plane directly under the package to provide a low-impedance return path and to limit simultaneous switching noise (SSN).
Place the JTAG TDI, TDO, TMS, TCK, and GND pins close to the connector or test pad so that programming cables have short stubs. If the design uses JTAG for boundary-scan production test, add a JTAG header that supports daisy-chaining multiple devices in compliance with IEEE 1149.1. Provide 4.7 kohm pull-ups on TMS and TDI, and place 22 ohm series resistors on TDO near the device to damp ringing on long board traces.
Estimated: the EPM7160EQC100-20 typically consumes 200-300 mA of Icc at maximum toggle frequency across all 84 I/Os. Designers often forget that EEPROM-programmed MAX 7000 devices require a 5 ms initialization cycle after VCC ramps up before the I/Os become active; do not depend on the CPLD for early power-on signals to the host CPU without adding external pull resistors on shared lines. Finally, verify that legacy boards converted to 3.3 V supply rails are not used - the EPM7160EQC100-20 will not operate correctly below 4.75 V on VCCINT.
Compliance Information
Legacy Altera MAX 7000 family parts were originally released in leaded PQFP packages and are generally NOT RoHS compliant per the Altera/Intel datasheet; lead-free variants carry the 'N' suffix (e.g., EPM7160EQC100-15N). AEC-Q100 automotive qualification is not applicable - this is a commercial-grade CPLD.
