EPM3128ATC100-10NS - MAX 3000A CPLD, 128 Macro, 100-TQFP | Intel
MPN: EPM3128ATC100-10NS ✗ Cuối đờiEPM3128ATC100-10NS Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macro-cell arrays with a programmable interconnect matrix. It sits between simple logic gates and FPGAs in the programmable logic hierarchy and is widely used for glue logic, bus interfacing, state-machine control, and power-up sequencing in digital systems. The MAX 3000A family belongs to Intel's (formerly Altera's) classic CPLD portfolio, providing instant-on, deterministic timing, and high pin-to-pin speed that FPGAs cannot match for small, fast, fixed-function blocks.
Key features of the EPM3128ATC100-10NS include 4.5 ns pin-to-pin logic delays with counter frequencies up to 227.3 MHz, programmable interconnect that allows any pin to drive any macro cell or I/O, and JTAG-based boundary-scan testing per IEEE 1149.1. The 80 available I/O pins (out of 100 total package pins) share 4 dedicated input clocks and a global clear network, while 3.3 V core operation keeps power dissipation low for industrial and consumer applications.
Architecturally, the device uses EEPROM-based configuration cells, providing non-volatile storage that retains the logic design without external memory. The MAX 3000A macro cells implement sum-of-products logic with configurable flip-flops and a wide fan-in AND-OR structure, while the interconnect matrix (the so-called "Programmable Interconnect Array" or PIA) routes signals between logic array blocks with predictable timing.
Typical applications include bus-interface bridging, address decoding and chip-select generation, state-machine and sequencer implementation, power-up and reset sequencing, peripheral I/O expansion, and glue-logic replacement of discrete 74-series TTL. Its 5 V-tolerant I/O and fast propagation delay also suit industrial control and motor-drive front ends.
When designing with this device, ensure VCCINT is a regulated 3.3 V and VCCIO is set according to the I/O logic level. Decoupling must include 0.1 uF and 1 uF capacitors placed within 5 mm of each supply pin. JTAG chain order should be planned before PCB layout to avoid re-spinning the board for testability.

Ứng dụng tiêu biểu
EPM3128ATC100-10NS phù hợp cho 6 Áp dụngs: Bus Interface Bridging, Address Decoding and Chip-Select Generation, Power-Up and Reset Sequencing, State Machine and Sequencer Implementation, Industrial Control and Motor Drive Front End, Peripheral I/O Expansion and Glue Logic Replacement.
Bus Interface Bridging
The EPM3128ATC100-10NS is well suited to bridge mismatched bus standards such as 8-bit or 16-bit parallel buses between microcontrollers and peripherals. Its 10 ns pin-to-pin delay and 227.3 MHz counter frequency enable fast address-latch and chip-select decoding without wait states, while MultiVolt I/O lets the same device sit on a 3.3 V microcontroller bus and a 5 V peripheral bus simultaneously. With 128 macro cells and 80 user I/Os, it can implement complete state machines for handshaking, bus arbitration, and protocol conversion (for example, 8080 to 6800 or SRAM to async FIFO) on a single chip.
Được đề xuất
Address Decoding and Chip-Select Generation
The wide AND-OR fan-in of MAX 3000A macro cells makes the EPM3128ATC100-10NS ideal for address-decoding glue logic. A single device can replace multiple 74LS138 / 74HC138 decoders, generating up to 16 or more chip-select outputs from a full 24-bit address bus with deterministic 10 ns propagation delay. This consolidation reduces board area, improves noise immunity, and allows late-stage address-map changes by simply reprogramming the EEPROM, eliminating board re-spins during prototyping.
Được đề xuất
Power-Up and Reset Sequencing
With its non-volatile EEPROM configuration and instant-on behavior, the EPM3128ATC100-10NS becomes a deterministic reset sequencer for multi-rail systems. Designers can program precise delays and dependency chains between power rails (for example, sequencing 1.8 V, 3.3 V, and 5 V rails at 10 ms intervals), using just a few macro cells per channel. The 80 user I/Os accommodate sequencing for 20+ rails, making the device suitable for ATCA, telecom backplane, and FPGA-bank power controllers.
Được đề xuất
State Machine and Sequencer Implementation
The EPM3128ATC100-10NS is purpose-built for synchronous state machines. Each macro cell contains a flip-flop with selectable clock, clear, and preset, plus wide AND-OR product terms capable of implementing complex Mealy or Moore machines in just a few cells. With 227.3 MHz counter frequency, designers can implement high-speed packet or protocol state machines running at 100 MHz or more, while the 80 I/Os serve multiple flag and handshake signals without external muxes.
Được đề xuất
Industrial Control and Motor Drive Front End
The 5 V-tolerant MultiVolt I/O of the EPM3128ATC100-10NS lets it accept inputs directly from 5 V Hall sensors, encoders, and opto-isolated feedback signals in industrial drives. Its 10 ns propagation delay enables sub-microsecond response to overcurrent and fault signals, critical for protecting IGBT modules. Industrial-grade variants within the same family extend operating temperature ranges. The TQFP-100 footprint is suitable for compact DIN-rail and panel-mount controllers.
Được đề xuất
Peripheral I/O Expansion and Glue Logic Replacement
Designers traditionally implement I/O expansion with 74-series TTL, requiring many small packages. The EPM3128ATC100-10NS consolidates dozens of 74LS00 / 74HC245 / 74LS273 functions into a single device, freeing PCB area for analog or RF sections. The 80 user I/Os handle wide data buses or many individual GPIO lines, while ISP support lets firmware revisions update the I/O map without a board change. Pin-compatible speed-grade variants (-7N) also drop into timing-marginal designs.

Ghi chú thiết kế
Estimated: at maximum toggle frequency of 227 MHz with 80 I/Os at 50% toggle rate, the EPM3128ATC100-10NS draws roughly 250-350 mA from VCCINT (3.3 V). Place one 0.1 uF and one 10 uF ceramic decoupling capacitor within 5 mm of each VCCINT and VCCIO pin, and add a 47 uF tantalum bulk capacitor near the regulator. Use a star-ground topology to isolate the CPLD return current from analog grounds.
The TQFP-100 has 0.5 mm lead pitch and is hand-solderable with care but requires hot-air or reflow for production. Keep all signal traces shorter than 50 mm when driving at 100 MHz, and use a 4-layer PCB with continuous ground and power planes. JTAG signals (TCK, TMS, TDI, TDO) should be routed with 22-33 ohm series damping resistors to suppress ringing on long programming cables.
Do not exceed VCCINT above 3.6 V or VCCIO above 4.0 V, or the EEPROM cells can be damaged. The OE1/OE2/global-clock pins must be configured in the Quartus II project before programming; otherwise inputs float and consume extra current. Boundary-scan chain order must include the EPM3128ATC100-10NS in the BSDL file or production test coverage will be incomplete. Avoid leaving unused I/Os floating - configure them as outputs driving low in the project file.
