Typical Applications
EPM7128SLI84-10 is suitable for 6 applications: ISA/PCI Bus Address Decoding, 5 V Industrial Control Logic, Legacy Microprocessor Peripheral Interface, State Machine Controllers, Glue Logic Consolidation, Test & Measurement Equipment Front-End.
ISA/PCI Bus Address Decoding
The EPM7128SLI84-10 is well-suited for ISA/PCI bus address decoding on legacy 5 V industrial motherboards. Its 10 ns tPD supports the 8 MHz ISA bus cycle time with ample margin, while the 68 user I/Os accommodate full 24-bit address plus 16-bit data control. The 128 macro cells implement 8-16 independent chip-select decoders, each with registered outputs and bus-request acknowledge logic, replacing dozens of 74-series GAL/PAL devices with a single non-volatile part. The EEPROM configuration preserves decode maps across power cycles - critical for industrial PCs that must boot deterministic I/O maps.
Recommended
5 V Industrial Control Logic
Industrial PLCs and motor-control boards benefit from the EPM7128SLI84-10's 5 V core and industrial -40 °C to +85 °C operating range. The 84-pin PLCC package is socket-compatible, enabling field replacement on legacy lines. Engineers use the 128 macro cells to implement PID control state machines, encoder-interface glue logic, and emergency-stop interlocks with deterministic 10 ns timing. The on-chip EEPROM stores configuration without an external boot ROM, and the JTAG ISP port allows firmware updates via the ByteBlaster cable without removing the part from the board.
Recommended
Legacy Microprocessor Peripheral Interface
The EPM7128SLI84-10 serves as a flexible peripheral interface for 8/16-bit microprocessors such as 8051, Z80, or 68k family, providing wait-state generation, bus multiplexing, memory-bank switching, and interrupt prioritization. Its 10 ns propagation delay accommodates 25 MHz 68k bus cycles without wait states, while the 68 I/Os handle full address/data/control plus chip-select generation for up to 8 peripherals. The non-volatile EEPROM configuration means the boot memory map is set without an external PROM, simplifying BOM and shortening time-to-market.
Recommended
State Machine Controllers
Designers use the EPM7128SLI84-10 to implement Moore and Mealy state machines for sequencing, traffic control, and protocol converters. With 128 macro cells each containing a flip-flop, the part can host 60-100 states with combinational output logic. The 10 ns tPD ensures state transitions complete within one 100 MHz clock cycle, enabling high-speed UART, SPI, or I2C bit-banging interfaces. ISP via JTAG permits state-table updates in the field without board removal, accelerating development iteration.
Recommended
Glue Logic Consolidation
The EPM7128SLI84-10 consolidates 10-20 discrete 74HC/74LS logic gates into a single 84-PLCC, reducing board area and improving reliability. A typical use case is replacing address latches, bus transceivers, parity generators, and interrupt controllers in a 5 V embedded system. The non-volatile EEPROM configuration eliminates the need for a boot PROM, and the 10 ns timing matches HC-logic performance while drawing lower quiescent current. Engineers gain design flexibility - logic changes require only a JTAG re-flash, not a board respin.
Recommended
Test & Measurement Equipment Front-End
Bench instruments and ATE fixtures use the EPM7128SLI84-10 for trigger conditioning, channel multiplexing, and pattern generation. The 68 user I/Os handle 32-channel logic-analyzer probe buffers or 16-channel digital-I/O multiplexing. The 10 ns propagation delay supports 50 MHz pattern-generation clock rates, while the industrial -40 °C to +85 °C range ensures operation in laboratory and factory environments. The non-volatile EEPROM configuration retains test patterns across power cycles - critical for production ATE where boot-time calibration is impractical.

Key Differentiators
- Industrial temperature grade with 10 ns tPD (vs EPM7128SLC84-10)
- Direct drop-in for legacy non-RoHS assemblies (vs EPM7128SLI84-10N)
- 5 V core for legacy 5 V-only designs (vs EPM7128ELC84-10)
Design Notes
The EPM7128SLI84-10 requires a stable 5.0 V ±5% supply on VCCINT pins (typically pins 3, 17, 41, 65 on the 84-PLCC). Place 0.1 µF decoupling capacitors within 5 mm of each VCC pin and a 10 µF bulk tantalum at the board supply entry. Estimated quiescent current at 100 MHz is approximately 200 mA; in power-save mode (unused LABs disabled), this drops to ~50 mA. Do not share the 5 V analog supply with switching regulators - use a ferrite bead or LC filter if the system has noisy DC-DC converters nearby.
Do not substitute the EPM7128SLI84-10 (MAX 7000S, 5 V core) with the EPM7128ELC84-10 (MAX 7000AE, 3.3 V core) without reworking the board power supply - applying 5 V to a 3.3 V core device will damage it. Similarly, the -10N suffix denotes lead-free RoHS plating; the original -10 has SnPb leads. Verify your assembly process (reflow profile for SnPb vs lead-free) before placing the order.
The 84-pin PLCC has 0.05 inch (1.27 mm) pitch J-lead perimeter pads and an exposed die pad for thermal dissipation. Use a PLCC socket (e.g., 3M Textool or Aries) for prototype boards to enable ISP re-programming without desoldering. For production, SMT soldering to PLCC land patterns requires careful paste-stencil aperture design - J-lead fillets should be inspected per IPC-A-610 Class 2. Maintain 8 mil trace/space rules on I/O banks to accommodate 68 signal pins exiting the perimeter.
Route JTAG signals (TCK, TMS, TDI, TDO) with 50 Ω controlled impedance and keep them short (<50 mm) to avoid signal-integrity issues at high programming-clock rates. Place the JTAG header at the board edge for convenient ByteBlaster cable access. The global clock (GCLK) and clear (GCLRn) pins should be routed with ground shielding to minimize crosstalk, and any high-speed output enables (OE1, OE2) should be terminated with 100 Ω series resistors if driving long traces (>50 mm).
Compliance Information
EPM7128SLI84-10 is non-RoHS due to SnPb lead finish; the -10N suffix denotes RoHS-compliant lead-free plating. Compliance status for REACH and conflict minerals was not available in the verified web data.
