Typical Applications
EPM7160SQC160-10N is suitable for 6 applications: 5V Legacy Bus Decoder and Address Mapping, Glue Logic Replacement for Discrete TTL/CMOS Gates, Peripheral Controllers (UART, FIFO, DMA), Industrial State Machines for Motor-Control Front-Ends, I/O Expansion for 8051/MCS-51 Embedded Designs, Custom Bus Arbiters and Interrupt Controllers.
5V Legacy Bus Decoder and Address Mapping
The EPM7160SQC160-10N fits 5V legacy bus-decoding applications because its 5.0V VCCINT and 5V-tolerant I/O eliminate the need for level shifters when interfacing with classic TTL peripherals, microcontrollers, and memory buses. Its 160 macrocells and 104 user I/O pins provide ample logic capacity to decode 24-bit or wider address ranges, generate chip-select signals for multiple peripherals, and implement wait-state insertion logic in a single device. The 10 ns tPD ensures that address-to-CS propagation remains well within ISA bus timing margins.
Recommended
Glue Logic Replacement for Discrete TTL/CMOS Gates
The EPM7160SQC160-10N replaces multiple discrete 74-series TTL and CMOS logic packages in retro-computing and industrial-control applications. With 160 macrocells, designers can integrate 10-20 standard logic functions (multiplexers, latches, encoders, parity generators) into one CPLD, reducing PCB area, BOM cost, and assembly complexity. The 5V supply and PQFP-160 surface-mount package suit retro ISA-bus and VMEbus boards where 5V tolerance is mandatory and leaded PQFPs survive hand-solder rework.
Recommended
Peripheral Controllers (UART, FIFO, DMA)
The EPM7160SQC160-10N suits peripheral-controller implementations such as custom UARTs, FIFO buffers, and DMA engines in embedded motherboards and test instruments. Its 167 MHz internal counter frequency and 10 ns combinatorial delay allow 100 MHz+ serial-baud generation and reliable state-machine sequencing for high-throughput DMA. The 104 user I/O pins accommodate 8/16-bit parallel FIFOs plus handshake/status flags, while JTAG ISP supports in-field firmware updates for production diagnostic boards.
Recommended
Industrial State Machines for Motor-Control Front-Ends
The EPM7160SQC160-10N serves industrial state-machine front-ends for stepper and BLDC motor-control boards where deterministic logic timing is required. Its EEPROM-based non-volatile configuration eliminates external boot memory and supports instant-on operation within 200 ms of power-up. The commercial 0 C to 70 C temperature range covers most factory-floor enclosures, and 5V I/O directly drives opto-isolated gate drivers and encoder inputs without additional buffering.
Recommended
I/O Expansion for 8051/MCS-51 Embedded Designs
The EPM7160SQC160-10N expands I/O in 8051/MCS-51-based embedded designs by providing 104 5V-tolerant user I/O pins accessible via memory-mapped registers. The CPLD decodes upper address lines and converts slow 8051 port operations into parallel multi-bit I/O cycles. With 10 ns tPD, address-to-output latency fits within standard 8051 MOVX timing without wait-state insertion. This pattern is common in legacy industrial controllers, security panels, and point-of-sale terminals still in production.
Recommended
Custom Bus Arbiters and Interrupt Controllers
The EPM7160SQC160-10N implements custom multi-master bus arbiters and interrupt controllers in VMEbus, Multibus, and proprietary backplane designs. With 160 macrocells, designers can encode priority logic, daisy-chain arbiters, and vectored interrupt tables in one device. The 5V supply matches legacy backplane signaling, and JTAG ISP allows late-stage priority-table updates during integration. The PQFP-160 package provides enough I/O for 32-bit data plus 16-bit arbitration/control signals with margin.

- MAX 7000S in-system programmability via JTAG (vs EPM7160EQC160-15 (MAX 7000E))
- Largest I/O count in EPM7160 PQFP-160 family (vs EPM7128SQC160-10N)
Design Notes
The EPM7160SQC160-10N requires a single 5.0V supply (VCCINT) with recommended tolerance of +/- 5% per the MAX 7000S datasheet. Decouple each VCC/VCCIO pair with a 0.1 uF ceramic capacitor placed within 5 mm of the package pin, plus a 10 uF tantalum bulk capacitor near the supply entry point. The device draws approximately 100-300 mA depending on logic utilization and toggle rate; provision for a 500 mA supply is recommended to handle in-rush during ISP programming.
Estimated: at 50% macrocell utilization, 100 MHz toggle rate, and 5V supply, the EPM7160SQC160-10N dissipates approximately 0.5-1.0 W. The PQFP-160 package has theta_JA of approximately 40 C/W (typical for leaded PQFP), giving a junction temperature rise of 20-40 C above ambient. Commercial temperature range (0 C to 70 C) is satisfied in standard office and industrial environments without active cooling. For enclosed chassis, verify theta_JC and derate if ambient exceeds 50 C.
Route JTAG signals (TDI, TDO, TMS, TCK) with short traces (< 50 mm) and avoid parallel routing with high-speed switching signals to prevent programming errors. The PQFP-160 package requires a 31.2 x 31.2 mm footprint with 0.65 mm pitch gull-wing leads; use a PCB land pattern compliant with IPC-7351 nominal-density standards. Reserve a 4-pin header for the JTAG download cable (ByteBlasterMV or USB-Blaster) accessible from the board edge.
Do not confuse the EPM7160SQC160-10N (PQFP-160, 160 macrocells) with the EPM7160SLC84-10 (PLCC-84, 64 macrocells) - these are NOT pin-compatible despite sharing the EPM7160 prefix. Always verify the package suffix (SQC = PQFP-160, SLC = PLCC-84, ELC = PLCC-84, SLI = PLCC-84 industrial) before PCB layout. Also note that MAX 7000S is 5V-only and is not compatible with 3.3V MAX II designs without a level-shifting interface.
Compliance Information
PQFP-160 package contains lead-bearing solder finish (non-RoHS). Reach SVHC compliance per Intel material declarations. AEC-Q100 not applicable - this is a commercial-grade CPLD. Choose MAX II EPM570 for new RoHS-compliant designs.
