Typical Applications
EPM7128SQC100-6 is suitable for 6 applications: PCI/Local-Bus Interface Bridge, 5V Industrial Glue Logic, JTAG-Controlled Scan and Boundary Test, Address Decoding and Interrupt Management, Legacy 74-Series Logic Consolidation, Telecom Backplane Control Logic.
PCI/Local-Bus Interface Bridge
The EPM7128SQC100-6's 6 ns tPD and 84 user I/Os make it a strong fit for PCI and local-bus interface bridging in legacy 5V motherboards and add-in cards. With 128 macrocells the device can hold bus-arbitration state machines, address decoders, and interrupt controllers in a single non-volatile CPLD. Its instant-on EEPROM configuration avoids the boot-time latency of SRAM-based FPGAs, which is critical for BIOS/POST logic that must be live at power-up. Used between the host chipset and peripheral slots, it reduces discrete 74LS glue-logic into a single re-programmable device that can be JTAG-upgraded in the field.
Recommended
5V Industrial Glue Logic
The EPM7128SQC100-6 directly replaces racks of 74LS/74HC discrete glue logic in 5V industrial control systems. Its 5V CMOS EEPROM process and MultiVolt I/O make it tolerant of 3.3V peripherals without level shifters, while 128 macrocells consolidate decoders, muxes, and sequencers into a single device. The 100-pin PQFP package provides enough I/O for 16-bit or 32-bit bus aggregation. Compared to a discrete-logic implementation, the CPLD reduces PCB area, eliminates propagation skew between gates, and allows last-minute logic changes via JTAG without board respins.
Recommended
JTAG-Controlled Scan and Boundary Test
The EPM7128SQC100-6's native IEEE 1149.1 JTAG port enables it to act as both a logic device and a JTAG controller/scan bridge in test fixtures and production ATE racks. Designers can daisy-chain multiple devices, implement custom JTAG instructions, and re-route test access without external multiplexer ICs. The non-volatile EEPROM configuration means the scan topology is live at power-up with no FPGA bitstream load delay. The 6 ns tPD ensures scan-clock and scan-data signals meet production-tester timing windows, while 84 user I/Os give plenty of test points for boundary-scan coverage.
Recommended
Address Decoding and Interrupt Management
In embedded motherboards the EPM7128SQC100-6 consolidates address decoding, chip-select generation, and interrupt priority management into a single deterministic device. With 6 ns pin-to-pin delay it meets ISA and similar legacy bus timing without wait states, and the 128 macrocells hold complete decode trees for memory and peripheral maps. Non-volatile configuration means the decode map is correct from the first clock cycle, eliminating the boot-time holes of SRAM FPGAs. The 100-pin PQFP package provides 84 I/Os for chip-select fan-out to multiple peripherals.
Recommended
Legacy 74-Series Logic Consolidation
Designers migrating racks of 74LS245, 74LS138, 74LS574, and similar glue-logic ICs onto a single programmable device commonly target the EPM7128SQC100-6 because it provides 128 macrocells and 84 I/Os in the same 5V electrical envelope. The 6 ns tPD matches or exceeds the propagation delay of the original discrete gates, while EEPROM non-volatility preserves the design even through power cycles. Compared to a discrete implementation, the CPLD reduces BOM count, simplifies PCB layout, and lets engineers re-route logic via JTAG without board re-spin.
Recommended
Telecom Backplane Control Logic
The EPM7128SQC100-6 is widely used in 5V telecom backplanes for control-plane glue logic between line-card ASICs, framer ICs, and supervisory processors. Its 5V tolerance and MultiVolt I/O let it bridge legacy 5V ASICs with newer 3.3V logic, while 84 I/Os accommodate backplane signal fan-out. With 6 ns tPD the device meets common telecom control-bus timing margins without introducing wait states. Non-volatile EEPROM and JTAG ISP allow field firmware updates and in-service reprogramming on live backplanes.

Key Differentiators
- Fastest speed grade in the MAX 7000S 100-pin PQFP family (vs EPM7128SQC100-7)
- Same die and footprint as slower speed-grade variants (vs EPM7128SQC100-10)
- RoHS/Pb-free alternatives available on the same footprint (vs EPM7128SQC100-10N / EPM7128SQC100-10F)
Design Notes
The EPM7128SQC100-6 operates from a single 5V VCC rail with MultiVolt I/O support. Decouple every VCC pin with a 0.1 uF ceramic capacitor placed as close as possible to the package, and add a bulk 10-47 uF tantalum or aluminum capacitor near the device. The 100-pin PQFP has multiple VCC and GND pins distributed around the package - connect all of them. Avoid routing high-speed switching signals (clocks, JTAG TCK) across VCC split planes to prevent power-plane noise coupling into the analog-style I/O cells.
Estimated: at 5V VCC and full 147.1 MHz operation across all 84 I/Os, the device consumes up to approximately 300-400 mW. The PQFP-100 package has a theta_JA around 50-60 C/W on a standard JEDEC test board, so junction temperature rise above ambient is roughly 15-25C. For sealed industrial enclosures without airflow, derate clock frequency or I/O toggling rate to keep junction below 125C. Provide copper area under and around the package to spread heat, and consider thermal vias to inner plane layers.
Use a 4-layer PCB with continuous ground plane beneath the PQFP-100 footprint to control impedance on JTAG and clock traces. Keep JTAG signals (TCK, TMS, TDI, TDO) short (<= 5 cm), series-terminated with 33 ohm resistors if TCK exceeds 10 MHz, and guarded by ground traces. Reserve a 4-pin JTAG header or boundary-scan connector footprint on every board that uses the EPM7128SQC100-6, even if you do not plan to use ISP immediately - it saves rework time when field updates are needed.
Do not confuse the EPM7128SQC100-6 with the MAX 7000A or MAX 3000A variants, which are 3.3V parts with different pinouts and JTAG chains. Always check the part marking for the 'S' suffix denoting the 5V MAX 7000S family and the -6 speed-grade suffix. Programming tools must target the MAX 7000S device ID in Quartus or MAX+PLUS II - selecting the wrong family will fail ID verification. Avoid mixing the SQC package with the PLCC-84 (SLC84) footprint, which is electrically similar but pin-incompatible at the board level.
