EPM7128SQC100-7 - 128-Macro 5V CPLD, 7.5ns, 100-Pin PQFP | Altera (Intel)
MPN: EPM7128SQC100-7 ✗ Cuối đờiEPM7128SQC100-7 Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic device that sits between discrete glue-logic ICs and larger FPGAs. Within the broader semiconductor taxonomy, the EPM7128SQC100-7 belongs to the CPLD category -> programmable logic -> digital IC -> semiconductor. MAX 7000S devices use a classic EEPROM-based architecture, providing deterministic timing, infinite reconfigurability (over 100 program/erase cycles), and 100% non-volatile storage so designs power up in a known state without external boot memory.
Key features include 2,500 usable gates, a maximum internal operating frequency of 125 MHz (with some sources citing up to 250 MHz internal), 5.0V VCCIO/VCCINT operation, in-system programmability through a standard 4-pin JTAG interface (IEEE Std 1149.1), and built-in support for the MAX+PLUS II and Quartus development flows. The device includes 128 macro cells, each composed of a programmable AND/OR array feeding a configurable flip-flop, and provides flexible I/O standards including TTL and CMOS.
Architecturally, the EPM7128SQC100-7 organizes its 128 macro cells into four Logic Array Blocks (LABs) interconnected through the Programmable Interconnect Array (PIA). This matrix-based interconnect delivers predictable, fixed-delay signal routing - a key advantage over SRAM-based FPGAs for deterministic glue-logic, bus-interface, address-decoding, and timing-critical applications where race conditions must be eliminated.
Typical applications include bus-interface bridging (e.g., 8-bit/16-bit microprocessor glue logic), address decoding and chip-select generation, state-machine controllers, peripheral interface expansion, and legacy 5V system designs that require non-volatile, instantly-on logic. The 84 available user I/Os accommodate wide parallel buses and multi-channel control logic.
When designing with this device, plan for a single 5V supply rail and verify that total output loading plus simultaneous switching I/O does not exceed the thermal envelope. For new designs, note that the MAX 7000 family is in legacy support - consider the MAX II or MAX V series for cost-sensitive modern designs, but the EPM7128 remains a proven solution for sustaining legacy 5V systems and as a pin-compatible firmware drop-in.

Ứng dụng tiêu biểu
EPM7128SQC100-7 phù hợp cho 6 Áp dụngs: Microprocessor Glue Logic and Address Decoding, Bus Interface Bridging and Protocol Conversion, State Machine Controllers, Peripheral Interface Expansion, Legacy 5V System Sustainment, Industrial Control and Instrumentation Front-End.
Microprocessor Glue Logic and Address Decoding
The EPM7128SQC100-7 excels at replacing discrete 74-series glue logic with a single 5V CPLD, consolidating address decoding, chip-select generation, wait-state insertion, and bus steering for 8/16/32-bit microprocessors. With 128 macro cells and 84 user I/Os, it can decode the full 24-bit address range of an 8086/MC68000 system, generate up to 12 chip selects, and provide bus-transceiver control signals in one device. The 7.5 ns pin-to-pin delay is short enough to qualify as a transparent address latch for zero-wait-state designs, while the deterministic PIA routing eliminates timing race conditions that plague SRAM-based FPGAs. Pair with a legacy 80C186 or MC68302 for robust embedded control.

Bus Interface Bridging and Protocol Conversion
Use the EPM7128SQC100-7 to bridge between legacy 5V parallel buses (ISA, PC/104, Z80, 8051 expanded I/O) and modern peripheral interfaces. Its 84 I/Os comfortably accommodate 16-bit data plus 24-bit address plus control signals, and the EEPROM-based non-volatile configuration means the bridge powers up instantly in the correct mode without boot delay. The 125 MHz internal frequency supports moderate-speed serial-to-parallel conversion, while deterministic routing keeps asynchronous handshakes race-free. The 5V tolerance of the I/O banks makes it ideal as a glue layer between 5V legacy ASICs and 3.3V peripherals, with external resistor dividers or transceivers on the lower-voltage side.
Được đề xuất
State Machine Controllers
The EPM7128SQC100-7 is well-suited for implementing complex state machines controlling industrial machinery, motor drives, or test equipment, where deterministic timing and one-chip integration outweigh the need for high gate counts. Each of the 128 macro cells provides a registered output with programmable clear/preset and clock enable, making Moore and Mealy machines trivial to encode. The 4 global clock inputs allow clean integration of asynchronous external events, and the JTAG TAP supports boundary-scan testing of the state machine outputs. Designers can simulate and verify the entire state machine in Quartus or MAX+PLUS II before downloading through JTAG.
Được đề xuất
Peripheral Interface Expansion
Expand I/O capabilities of microcontrollers or microprocessors with the EPM7128SQC100-7, adding PWM generators, quadrature decoders, 7-segment display multiplexers, or keypad scanners in a single 5V CPLD. With 84 user I/Os, the device can directly drive up to eleven 8-segment multiplexed displays, scan an 8x8 matrix keypad, and provide 16 channels of PWM with under 8 ns propagation delay. The non-volatile EEPROM-based configuration lets the design power up instantly without firmware initialization, which is critical in hard real-time control loops. The 5V VCCIO is bus-compatible with TTL and CMOS peripherals from the 1980s and 1990s still common in industrial equipment.
Được đề xuất
Legacy 5V System Sustainment
The EPM7128SQC100-7 is an ideal sustainment solution for sustaining legacy 5V boards where a redesign is impractical - aerospace, medical, and industrial equipment with multi-decade service lives often need spare-part replacements for obsolete logic. Because the part is non-volatile and instantly-on, replacement is solder-and-go with no firmware reloading required if the JEDEC image is preserved. For boards designed before 2010, the EPM7128SQC100-7 is often the only practical option to keep production lines running. Combine with periodic board-level burn-in to qualify refurbished inventory.
Được đề xuất
Industrial Control and Instrumentation Front-End
Implement custom front-end signal conditioning, multiplexing, and timing for industrial instrumentation with the EPM7128SQC100-7. Its 84 I/Os handle multi-channel analog switch steering, ADC/DAC timing, and trigger logic, while the 5V I/O banks are tolerant of 24V industrial bus signals through external resistive dividers or opto-isolators. The 7.5 ns tPD supports sub-microsecond timing accuracy needed for encoder decoding and trigger synchronization. Combined with the IEEE 1149.1 JTAG interface, the design supports boundary-scan testability required in many industrial safety standards. Use as a 'smart' front-end to a microcontroller that handles high-level protocol processing.

Ghi chú thiết kế
The EPM7128SQC100-7 requires a single 5.0V supply on every VCC pin (multiple VCC pins distributed around the package). Place a 0.1 uF decoupling capacitor adjacent to each VCC pin and a 10 uF bulk tantalum capacitor at the board's power-entry point. Although the device is non-volatile and instantly-on, the I/O banks can drive large load currents when switching simultaneously - peak transient current can exceed the steady-state ICC. A well-bypassed 5V rail is essential for reliable JTAG programming and clean logic operation. Source: MAX 7000 family datasheet Power-Supply section.
The 100-pin PQFP package has 0.65 mm lead pitch and gull-wing leads - PCB land patterns must follow IPC-7351 nominal-density guidelines and include generous solder mask slivers between pads. Place the CPLD close to the 5V regulator to minimize supply-trace inductance, and route JTAG signals (TDI, TDO, TMS, TCK) with controlled impedance if the JTAG cable exceeds 150 mm. Add a JTAG header (2x5 2.54 mm) on the board edge for in-system programming without removing the device. Per the datasheet's Pin Connection section, unused I/O pins should be left floating or configured as outputs driving low to minimize ICC.
Estimated: When migrating from EPM7128SQC100-7 to the ATF1508AS-7AX100 (Microchip), use Microchip's POF2JED tool to translate the original Altera POF programming file to an ATF JED file. While the silicon is pin-compatible and functionally similar, the architecture differs enough that a one-to-one JED file will NOT work - the conversion tool is required. Additionally, do not confuse PQFP-100 (this part) with TQFP-100 (the EPM7128STC100-7 variant) - the package outlines differ and the parts are NOT PCB-compatible despite both having 100 pins. Verify the exact package code 'QC' (PQFP) vs 'TC' (TQFP) before board layout.
The EPM7128SQC100-7 in PQFP-100 has a thermal resistance (theta_JA) of approximately 45 C/W in still air, which is adequate for typical glue-logic workloads. However, designs with many simultaneously-switching outputs can push junction temperature up - estimate: 84 outputs switching at 10 MHz with 50 pF load each dissipates roughly (84 * 10e6 * 50e-12 * 5^2) = 1.05 W additional dynamic power. Verify thermal envelope using the datasheet's Power Calculator and consider adding thermal vias under the exposed die pad area on multi-layer boards.
