A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that sits between simple SPLDs/GALs and higher-density FPGAs in the programmable logic hierarchy: SPLD < CPLD < FPGA. MAX 7000A devices use second-generation Multiple Array MatriX (MAX) architecture with each LAB containing 16 macrocells, and provide instant-on (zero-power) EEPROM configuration cells, JTAG-based IEEE Std 1149.1 boundary-scan testing, and 3.3V in-system programmability (ISP) through the built-in JTAG interface. Compared with SRAM-based FPGAs, a CPLD boots in microseconds without an external boot PROM, making it ideal for deterministic power-on logic and bus arbitration.
Key features of the EPM7128ATC100-7F include 2.5K usable gates, 128 macrocells, 100 user I/O pins, a 7.5 ns tPD with 116.3 MHz fMAX, 3.0V-3.6V core supply with 2.5V/3.3V multi-voltage I/O support, JTAG IEEE 1149.1 boundary-scan, in-system programmability through JTAG, and four user-defined I/O banks with MultiVolt I/O interfacing. The 100-TQFP (14x14 mm) package is suitable for industrial-temperature (-40C to +85C) designs.
The architecture combines a programmable interconnect array with 16-macrocell LABs, an EEPROM configuration memory, and a JTAG controller; each macrocell contains a programmable AND/OR array, a flip-flop, and product-term allocation logic for combinational or registered logic synthesis. MultiVolt I/O pins tolerate mixed 1.8V/2.5V/3.3V/5V interfaces, allowing direct connection to legacy 5V devices through a simple series resistor or level translator.
Typical applications include PCI/ISA bus interface glue logic, address decoding and chip-select generation, state-machine and sequencer controllers, power-sequencing logic, asynchronous interface bridging (UART, I2C, SPI), legacy 5V-to-3.3V bus translation, and industrial control glue logic. The deterministic 7.5 ns propagation delay is well suited to decode-driven control paths where timing margins must be guaranteed at first silicon.
When designing with this device, plan for a 3.3V core supply (3.0V-3.6V) and a JTAG chain (TCK/TMS/TDI/TDO plus optional TRST) for ISP. Confirm Quartus MAX+PLUS II support for legacy MAX 7000A bitstreams before migrating from older MAX+PLUS toolchains, and reserve four pins for JTAG if boundary-scan is required in production test.

عام استعمالات
EPM7128ATC100-7F کے لیے موزوں ہے 6 ایپلیکیشنs: PCI / ISA Bus Glue Logic, Address Decoding & Chip-Select Generation, State Machine & Sequencer Controller, Legacy 5V to 3.3V Bus Translator, Power-Sequencing & Reset Logic, Asynchronous Interface Bridging (UART / SPI / I2C).
PCI / ISA Bus Glue Logic
The EPM7128ATC100-7F is a strong fit for PCI/ISA bus glue logic where deterministic sub-10 ns timing is mandatory: address decoding, chip-select generation, wait-state insertion, and bus arbitration all benefit from the part's 7.5 ns pin-to-pin propagation delay and 116.3 MHz fMAX. With 128 macrocells and 84+ user I/Os, it can replace multiple 74-series glue-logic packages on legacy ISA cards while reducing board area and BOM count. The 3.3V core with 5V-tolerant MultiVolt I/O lets it bridge directly to older 5V peripherals through a simple series resistor, easing migration of legacy industrial PCs without redesigning the entire backplane.

Address Decoding & Chip-Select Generation
Use the EPM7128ATC100-7F as a centralized address decoder to generate chip-select, output-enable, and write-enable signals for memory banks and peripherals sharing a common bus. Each macrocell can implement a wide product-term AND/OR decode, and the device's 100 user I/Os comfortably handle up to a 24-bit address plus 8-bit chip-select fan-out. The 7.5 ns tPD keeps decoded strobes inside a single 33 MHz PCI cycle (30 ns period), eliminating metastability risk and removing the need for an external decoder PAL. Engineers can revision-fix decode bugs in seconds by recompiling the EEPROM bitstream via JTAG.

State Machine & Sequencer Controller
The EPM7128ATC100-7F excels as a finite state machine controller for power-sequencer, motor-control, or industrial-automation logic. Each of its 128 macrocells contains a flip-flop and dedicated product-term allocation logic, allowing up to 128 registered states per device with combinational glue logic on the same die. The non-volatile EEPROM configuration means the sequencer boots in microseconds at power-on - critical for fail-safe controllers where an SRAM-based FPGA would otherwise need an external boot PROM and add tens of milliseconds to startup. Quartus II synthesis of legacy .tdf or .vhd state-machine code yields predictable timing reports that match silicon behavior within one tPD.

Legacy 5V to 3.3V Bus Translator
The EPM7128ATC100-7F's MultiVolt I/O makes it a practical bridge between legacy 5V peripherals and modern 3.3V processors or ASICs. Each I/O bank can be independently powered at 2.5V or 3.3V, and the inputs tolerate 5V signals through a 100 ohm series resistor, eliminating dedicated level-shifter ICs. The CPLD can also implement bidirectional bus switches and direction-control logic in the same device, reducing the bill of materials on mixed-voltage adapter boards. With 84+ I/Os available, a single EPM7128ATC100-7F can translate a full 8/16/32-bit data bus plus handshaking signals in one package.

Power-Sequencing & Reset Logic
Power-sequencing logic for multi-rail systems is a natural fit for the EPM7128ATC100-7F: instant-on EEPROM configuration means rail-ordering signals are valid within microseconds of VCCINT reaching regulation, without the boot delay of an SRAM FPGA. The 7.5 ns tPD supports fast Power-Good cascades and programmable watchdog timers for FPGAs, ASICs, and microprocessors that require specific rail-up/down ordering per their datasheets. Built-in JTAG (IEEE 1149.1) boundary-scan lets production test verify every power-sequencing net is correctly wired before the rest of the board is powered up.

Asynchronous Interface Bridging (UART / SPI / I2C)
Bridging asynchronous peripherals to a host bus is a classic CPLD application, and the EPM7128ATC100-7F brings 128 macrocells and 100 user I/Os to handle multi-channel UART, SPI master/slave, and I2C controller/slave bridges in a single device. Each macrocell implements the bit-banging or state-machine logic with deterministic sub-10 ns timing, which is critical when emulating an I2C master at 400 kHz Fast-mode or driving multiple SPI slaves with precise chip-select skew. Compared with bit-banging on a microcontroller, the CPLD approach offloads deterministic real-time work from the host CPU and runs in parallel without scheduler jitter.

ڈیزائن نوٹس
The EPM7128ATC100-7F requires a 3.0V-3.6V core supply on VCCINT plus one or more 2.5V/3.3V supplies on the VCCIO bank pins (VCCIO1-VCCIO4). Estimated: at 100% utilization with all 128 macrocells toggling at 116 MHz, the device draws roughly 250-400 mA from VCCINT, so place 0.1 uF X7R decoupling caps within 5 mm of every VCCINT/VCCIO pin and a single 10 uF bulk tantalum near the package. Sharing a 3.3V rail with a noisy switching converter is acceptable for logic but adds jitter to clock nets - keep a ferrite bead between switching and CPLD supplies.
Route JTAG signals (TCK, TMS, TDI, TDO) as a 4-wire daisy-chain with optional TRST, keeping total stub length under 25 mm and using 10 kohm pull-ups on TMS, TDI, and TRST to prevent accidental JTAG state-machine entry at power-up. The 100-pin TQFP has 0.5 mm pitch, which is hand-solderable with a fine tip but requires a hot-plate or reflow profile (ramp 1-2 C/s, peak 245 C, 60 s above 220 C) for reliable assembly. Decoupling caps should sit on the same side as the CPLD to minimize loop inductance.
Common pitfalls with the EPM7128ATC100-7F include: (1) forgetting the JTAG chain reservation when board space is tight - all four JTAG pins must remain accessible for ISP; (2) mixing 5V inputs directly into MultiVolt I/O without a series resistor, which overstresses the input clamp diodes; (3) using the device outside Quartus MAX+PLUS II legacy support, since newer Quartus versions dropped MAX 7000A synthesis - confirm tool support before starting a new design. Also note the part is NRD (Not Recommended for New Designs), so plan a migration path to MAX II or MAX V for new product development.
