EPM7128ATI100-10 Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocells with a central interconnect matrix, providing deterministic timing, instant-on operation, and high fan-in. Within the broader taxonomy, a CPLD sits between simple SPLDs (PALs/GALs) and FPGAs: it offers more logic capacity and I/O than an SPLD but lower logic density, lower power, and simpler timing closure than an FPGA. The MAX 7000A series belongs to the EEPROM-based CPLD class, which permits in-system programmability (ISP) via IEEE Std. 1149.1 JTAG and retains configuration without an external boot PROM.
Key features of the EPM7128ATI100-10 include 2,500 usable gates, a 3.0V to 3.6V single-supply operation, an internal supply voltage of 3.3V, four dedicated inputs used as global clock/clear/Output-Enable controls, and an in-system programmable EEPROM configuration cell. The device supports MultiVolt I/O allowing interface to 2.5V, 3.3V, and 5.0V systems, and includes built-in JTAG boundary-scan test support. Industrial operating temperature grade (-40C to +85C) is indicated by the 'I' suffix in the part number.
Architecturally, the MAX 7000A uses a second-generation Multiple Array Matrix (MAX) architecture with an enhanced interconnect scheme that reduces signal skew and improves timing predictability. Each LAB contains 16 macrocells sharing a common product-term array, and the programmable interconnect array (PIA) routes any LAB output to any other LAB input, giving designers full routing flexibility. The CMOS EEPROM process provides zero standby power for the configuration memory and supports 100 program/erase cycles.
Typical applications include bus-interface bridging (e.g., 8-bit/16-bit microprocessor to peripheral glue logic), address decoding, state-machine controllers, synchronous/ asynchronous FIFO control, peripheral reconfiguration in telecom/networking line cards, industrial control logic, and as a low-cost pin-compatible replacement for legacy 5V MAX 7000 designs where 3.3V operation is acceptable. The 100-pin TQFP footprint is widely supported and offers generous I/O for bus and glue-logic applications.
When designing with this part, observe the recommended decoupling scheme (one 0.1 uF plus one 10 uF bulk per supply pin) and route JTAG signals (TCK, TMS, TDI, TDO, TRST) with short, parallel traces to maintain signal integrity. Programming voltage is generated internally; no external 12V VPP is required. For new designs, verify the latest Altera/Intel Quartus support status before committing, as legacy MAX 7000A devices are supported primarily for in-system updates to existing products.

Applications typiques
EPM7128ATI100-10 convient pour 6 applications: Microprocessor Bus Interface & Glue Logic, Address Decoding & Chip-Select Generation, State-Machine & Sequencer Controllers, Telecom Line-Card Glue & Network Peripherals, Industrial Control & Automation Logic, Legacy 5V-to-3.3V System Migration Bridge.
Microprocessor Bus Interface & Glue Logic
The EPM7128ATI100-10's 128 macrocells and 68 user I/O make it well-suited for bridging 8/16/32-bit microprocessors to peripherals with mismatched bus widths or voltage levels. With 10 ns pin-to-pin delay it easily meets the setup/hold timing of 40-66 MHz processor buses, and its MultiVolt I/O enables direct connection to 5V peripherals from a 3.3V CPLD supply. The deterministic timing of the MAX 7000A architecture eliminates the timing-closure iterations typical of FPGAs.
Recommandé
Address Decoding & Chip-Select Generation
Address decoding for memory-mapped peripherals and chip-select generation in embedded systems is a canonical CPLD application that exploits the EPM7128ATI100-10's wide product-term logic and 10 ns propagation delay. Each macrocell supports up to 32 product terms, allowing complex address-match equations across 24-bit address spaces with single-clock latency. Industrial -40C to +85C operation makes the part suitable for factory-floor controllers and outdoor telecom equipment.
Recommandé
State-Machine & Sequencer Controllers
State machines for protocol engines (UART, SPI, I2C controllers), motor-control sequencers, and test-equipment timing benefit from the EPM7128ATI100-10's deterministic 10 ns tPD and zero-power CMOS EEPROM configuration. 128 macrocells provide enough capacity for 16-32 state FSMs with extensive output decoding, and the 4 LAB architecture gives predictable placement and routing. Instant-on operation eliminates the boot-time delay common to SRAM-based FPGAs.
Recommandé
Telecom Line-Card Glue & Network Peripherals
The EPM7128ATI100-10's MultiVolt I/O (2.5V/3.3V/5V tolerant) and industrial temperature grade suit telecom line cards for T1/E1, DSLAM, and legacy SONET/SDH equipment, where it performs bus-width adaptation, clock-domain crossing, and interrupt-aggregation glue. Its 100-pin TQFP footprint exposes 68 user I/O - sufficient for 8-bit TDM buses plus supervisory I/O. JTAG boundary-scan support enables in-system test (BST) for board-level manufacturing coverage.
Recommandé
Industrial Control & Automation Logic
In PLCs, motor drives, and process-control I/O modules, the EPM7128ATI100-10 replaces discrete 74-series glue logic with a single integrated device, reducing PCB area by 60-70% and improving field reliability. Industrial -40C to +85C operation handles factory-floor thermal extremes, and the EEPROM-based configuration retains logic through power cycles without a boot PROM. 128 macrocells comfortably fit encoder/decoder logic, watchdog timers, and isolated-signal conditioning sequencers.
Recommandé
Legacy 5V-to-3.3V System Migration Bridge
When migrating a legacy 5V MAX 7000 design to 3.3V, the EPM7128ATI100-10 provides a near-identical function with 2.5V/3.3V/5V-tolerant I/O that can interface directly to existing 5V peripherals on input pins, simplifying board rework. The 100-pin TQFP package pinout matches the 5V MAX 7000 family in the same footprint, allowing re-use of existing PCB layouts. Designers should verify all VCC pins are re-routed to 3.3V and that 5V-only output drive strengths are within receiver tolerances.

Notes de conception
The EPM7128ATI100-10 requires a clean 3.3V supply; place one 0.1 uF decoupling capacitor adjacent to every VCCINT/VCCIO pin pair and one bulk 10 uF tantalum or ceramic capacitor at the supply entry. The MAX 7000A draws up to 300 mA peak during ISP programming - ensure the regulator can sustain this transient. Power sequencing is not required, but supply rise time should be faster than 1 ms to guarantee correct power-on-reset of the EEPROM configuration logic.
Route JTAG signals (TCK, TMS, TDI, TDO, TRST) as a bus with no stubs, keeping the total trace length under 100 mm and using 22-33 ohm series termination at the driver when run length exceeds 50 mm. Maintain continuous ground return under the JTAG bus and avoid crossing any switching signals. Place the CPLD's VCCINT and VCCIO pins such that decoupling capacitors have minimal loop area; each capacitor should be no more than 3 mm from its associated supply pin.
Do not apply 5V to any output pin - the MAX 7000A I/O is 5V-tolerant only on input pins when VCCIO is 3.3V; outputs must never exceed VCCIO. Always enable the JTAG TRST pin (tie to logic-low through 1 kohm or drive low) to prevent inadvertent JTAG state-machine transitions at power-up. Verify that the BSDL file used for boundary-scan matches the exact -10 speed grade; mismatched speed grades produce false timing failures during manufacturing test.
The 10 ns tPD specification assumes a standard 50 pF load; for high-fanout designs (greater than 8 loads per output) use the slower tPD derating curves in the datasheet or buffer heavily-loaded nets. When interfacing to 5V receivers, confirm that VOH(min) at 3.3V exceeds the receiver VIH(min); some legacy TTL parts require 2.4V VOH which the MAX 7000A can meet only when I/O pins are configured as TTL-compatible (not CMOS) outputs.
