Typical Applications
EPM7160SQC160-6 is suitable for 6 applications: 32-bit PCI/ISA Bus Address Decoding, Microprocessor Glue Logic and Chip-Select Generation, Industrial State Machine Controllers, Legacy I/O Expansion for Microcontrollers, Telecommunications Bus Arbitration and Routing, Educational and Prototyping Logic Platforms.
32-bit PCI/ISA Bus Address Decoding
The EPM7160SQC160-6 is purpose-built for 32-bit and 16-bit peripheral address decoding in PCI, ISA, and VME bus systems. Its 160 macrocells are sufficient to implement 8-12 independent chip-select decoders for memory and peripheral banks, while the 6 ns pin-to-pin propagation delay keeps the decoder latency within a single 33 MHz PCI clock cycle (~30 ns clock-to-decode margin). With 104 user I/Os, designers can route 24-bit address lines plus several control signals directly into the device. The deterministic timing of the MAX 7000S architecture removes setup-time ambiguity that would otherwise force the use of faster SRAM-based FPGAs. Designers should place the device close to the CPU/memory bus to minimize input skew and use per-pin slew-rate control on the chip-select outputs to limit bus-edge ringing. The 5 V ISP allows in-system firmware updates when new memory maps are added.

Microprocessor Glue Logic and Chip-Select Generation
The EPM7160SQC160-6 is widely used as glue logic between microprocessors, microcontrollers, and peripheral/memory devices where multiple chip-select signals, wait-state generation, and bus-cycle translation are required. With 160 macrocells, designers can implement 6-10 independent state machines for handshake conversion (e.g., 8051 external memory cycles, Motorola bus arbitration). The 104 user I/Os comfortably absorb 32-bit data plus 24-bit address plus control signals with margin. The 6 ns propagation delay is faster than most CPU cycle times, ensuring the chip-select outputs settle before the next peripheral access. JTAG ISP allows board-level rework to fix bus-mapping bugs without removing the part. For designs that need wider buses, the same PQFP-160 footprint also accepts EPM7192SQC160-10 with 192 macrocells in the same pinout.
Recommended
Industrial State Machine Controllers
The EPM7160SQC160-6 serves as a deterministic state-machine controller in industrial automation, motor control, and process-control equipment where predictable response time is critical. EEPROM-based MAX 7000S devices deliver instant-on behavior (no external boot ROM, no wait state) and the 6 ns propagation delay gives response times suitable for 50 kHz encoder feedback loops and stepper-motor pulse trains. The 160 macrocells can implement 8-12 parallel FSMs for multi-axis motion controllers. Commercial temperature range (0 to 70 C) covers most factory-floor enclosures; for harsher environments, an industrial-grade variant is recommended. JTAG ISP enables field firmware updates via on-board test headers.
Recommended
Legacy I/O Expansion for Microcontrollers
The EPM7160SQC160-6 adds 104 general-purpose I/O lines to legacy microcontrollers (8051, 68HC11, PIC16/18) that have limited native I/O counts, eliminating the need for discrete 74-series logic. The 160 macrocells implement parallel-to-serial multiplexers (such as 8255 PPI functions), key-scan encoders, and seven-segment display drivers in a single device. EEPROM configuration means no boot code is required, freeing the microcontroller from external memory cycles. The 5 V supply matches the legacy MCU's logic levels, eliminating level translation. Engineers typically allocate 30-40 macrocells per I/O-bank decoder and 8-12 macrocells per bit-banged protocol engine.
Recommended
Telecommunications Bus Arbitration and Routing
In telecommunications equipment (T1/E1 framers, SONET/SDH tributaries, DSLAM line cards), the EPM7160SQC160-6 is used as a high-density bus arbiter and protocol-format converter between backplane buses and DSP/microcontroller subsystems. The 6 ns timing accommodates 50 MHz H.110/CT-bus cycles with comfortable margin. 160 macrocells can implement multi-master arbitration trees, HDLC framing buffers, and clock-recovery glue logic in one device. The 5 V core logic integrates naturally with older telecom backplanes that operate from 5 V. JTAG boundary-scan (IEEE 1149.1) helps with board-level test coverage in dense telecom assemblies.
Recommended
Educational and Prototyping Logic Platforms
The EPM7160SQC160-6 is popular in university curricula and prototyping platforms (MAX+PLUS II training boards, Altera UP-1/UP-2 development kits, retrocomputing CPLD boards) because it provides sufficient density (160 macrocells, 104 I/Os) to implement full 8-bit CPUs, VGA controllers, and classic arcade-game logic. The 5 V supply matches TTL lab equipment, and the 160-pin PQFP is breadboard-friendly with carrier adapters. Students can program the part with the free MAX+PLUS II BASELINE toolchain and learn deterministic timing without the complexities of SRAM FPGAs. The device's JTAG ISP allows multiple program/erase cycles in lab use without special sockets.

Key Differentiators
- Fastest speed grade in the MAX 7000S 160-macrocell family (vs EPM7160SQC160-10N)
- True drop-in replacement availability within the same PQFP-160 footprint (vs EPM7160SQC160-10N)
- EEPROM-based ISP eliminates external boot memory (vs SRAM-based FPGAs)
Design Notes
The EPM7160SQC160-6 requires a clean 5 V ±5% supply (4.75 V to 5.25 V) on VCC pins distributed around the package. Estimated: each VCC/GND pair should be decoupled with a 0.1 µF ceramic capacitor placed within 5 mm of the package pin to suppress switching noise; a bulk 10 µF tantalum at the board-level supply is recommended. Multiple VCC pins must all be connected; leaving any VCC pin floating can cause logic errors and increased EMI.
Do not assume the EPM7160SQC160-6 is JTAG-programmable in-circuit on any board: ISP requires 5 V tolerant JTAG drivers on TDI/TDO/TMS/TCK and a proper TRST or pull-up configuration. Designs that route the JTAG pins to user I/O without isolating the JTAG chain may fail programming. The dedicated inputs (GCLK1, GCLRn, OE1, OE2/GCLK2) cannot be repurposed as user I/O - they must remain routed to their clock/clear/OE signals or tied off via the Quartus/MAX+PLUS II pin assignments.
The 160-pin PQFP package has 0.65 mm pitch gull-wing leads on a 28x28 mm body; PCB layout should use at least 0.20 mm trace/space rules and 0.40 mm-wide solder paste apertures for reliable reflow. Estimated: a 4-layer stack-up with dedicated ground and power planes directly under the PQFP-160 keeps the EMI signature low and provides low-impedance return paths for the 104 I/O signals. Per-pin slew-rate control should be enabled on outputs driving long traces (>50 mm) to reduce ringing.
The MAX 7000S family is a CMOS CPLD and dissipates relatively little power at low toggle rates (typical quiescent current is in the low mA range). Estimated: under worst-case 100% toggle activity at 167 MHz on all 104 I/Os, total device dissipation stays below 1 W, well within the PQFP-160 thermal envelope. No heatsink is required for commercial 0-70 C operation. However, sustained operation near 70 C with high I/O switching should still be verified with a thermal probe on the package top.
Compliance Information
The EPM7160SQC160-6 was originally released before RoHS directives took effect and was sold with SnPb lead finish; lead-free (Pb-free) suffix variants may exist as EPM7160SQC160-6N or EPM7160SQC160-6G. REACH SVHC status is compliant per legacy distributor disclosures. AEC-Q100 is not applicable (commercial temperature grade only).
