EPM7128STC100-7 概要
A Complex Programmable Logic Device (CPLD) is a non-volatile programmable IC that combines multiple PAL-like macrocell blocks on a single die with a programmable interconnect matrix. In the system hierarchy, the CPLD sits between discrete 74-series glue logic and an FPGA, offering deterministic timing, instant-on behavior from on-chip EEPROM, and typically 30-600 macrocells per device. Because the configuration is stored in non-volatile memory, MAX 7000S CPLDs boot in microseconds with no external boot PROM, making them ideal for power-on control, I/O expansion and bus bridging.
Key features of the EPM7128STC100-7 include 128 macrocells distributed across 8 logic array blocks (LABs) of 16 macrocells each, 84 available user I/O pins, and a 36-input programmable interconnect network. The device supports 5V in-system programmability (ISP) via JTAG (IEEE 1149.1), multi-volt I/O interfacing (3.3V and 5V), and per-pin programmable slew rate and open-drain control. Each macrocell provides a programmable flip-flop with D, T, JK or SR modes, plus configurable product-term steering for combinatorial or registered outputs.
The MAX 7000S architecture uses Altera's classic second-generation EEPROM-based logic elements with a unified global routing pool, which yields predictable timing independent of design placement. The 7.5 ns tPD figure is valid across commercial temperature and voltage ranges, allowing the device to replace multiple discrete TTL/CMOS 74-series packages while reducing board area and improving design flexibility through software-based logic changes.
Typical applications include address decoding and bus-interface logic in microprocessor and DSP systems, peripheral glue logic in embedded designs, state-machine controllers, and 5V I/O expansion for ASICs and microcontrollers. Industrial automation and legacy equipment upgrades also leverage the MAX 7000S for backward-compatible 5V logic integration.
When designing with the EPM7128STC100-7, ensure each I/O pin's output enable and slew rate are configured in the Quartus II / MAX+PLUS II fitting tool to match signal integrity targets. JTAG chain ordering must be defined to allow in-field reprogramming, and unused pins should be set to "As input tri-stated" to minimize power and EMI.

主な用途
EPM7128STC100-7 の用途: 6 件s: Microprocessor Address Decoding and Bus Glue Logic, DSP and ASIC Peripheral Expansion, Industrial Control State-Machine Controllers, Legacy 5V I/O Expansion for Microcontrollers, Telecom and Networking Glue Logic, Test and Measurement Front-End Logic.
Microprocessor Address Decoding and Bus Glue Logic
The EPM7128STC100-7 is well-suited to microprocessor address decoding and bus-interface glue logic. Its 128 macrocells and 84 user I/Os can replace dozens of 74-series packages while fitting into one 100-pin TQFP. The 7.5 ns tPD ensures chip-select and interrupt signals propagate before the next memory cycle, and the non-volatile EEPROM boot means the decoder is active at power-on with no boot delay. Pair it with a 5V host MCU such as the 8051 or 68k family; the 5V core voltage matches the host rail directly, eliminating level shifters.
おすすめ
DSP and ASIC Peripheral Expansion
In DSP and ASIC systems, the EPM7128STC100-7 provides flexible peripheral expansion, implementing FIFO controllers, custom serial interfaces (UART/SPI/I2C bridges), and timing generators that the host processor cannot efficiently handle in software. The 128 macrocells comfortably fit a multi-channel UART plus DMA handshaking logic. With 84 I/Os and 5V native signalling, it interfaces directly to legacy peripheral ICs without level translation, simplifying PCB layout. The JTAG ISP allows in-field firmware upgrades over the same JTAG chain used for the host DSP.
おすすめ
Industrial Control State-Machine Controllers
The EPM7128STC100-7 is widely used in industrial control state machines and discrete-logic replacement in PLCs, motor controllers, and process automation equipment. Its deterministic 7.5 ns tPD and 125 MHz internal frequency guarantee cycle-accurate control of relays, contactors, and PWM signals. The non-volatile EEPROM boot and 5V I/O tolerance match the industrial 24V-interface backplane designs after opto-isolation. Designers appreciate the ability to modify state machines via JTAG ISP without pulling boards from service.
おすすめ
Legacy 5V I/O Expansion for Microcontrollers
The EPM7128STC100-7 adds general-purpose 5V I/O expansion to 3.3V microcontrollers. A modern Cortex-M or RISC-V host can offload keypad scanning, LCD control, and LED multiplexing to the CPLD, freeing the MCU to focus on application logic. The 84 user I/Os map directly to 7-segment displays, matrix keypads, and GPIO expanders. Because MAX 7000S supports multi-volt I/O on selected banks, the CPLD can bridge a 3.3V MCU to a 5V peripheral bus with no external translator. The instant-on EEPROM boot enables display and keypad handling at the earliest power-on moment.
おすすめ
Telecom and Networking Glue Logic
In telecom and networking line cards, the EPM7128STC100-7 implements custom PHY/MAC glue logic, clock muxes, and interrupt aggregators that do not warrant a full FPGA. The 84 I/Os connect to multi-gigabit transceivers, switch fabric ports, and management EEPROMs with deterministic timing suitable for synchronous buses. The 5V I/O matches legacy TDM buses, and the JTAG chain integration simplifies board-level boundary-scan testing during manufacturing. The non-volatile boot ensures the network element reaches a safe state at power-on before any software runs.
おすすめ
Test and Measurement Front-End Logic
In bench-top test and measurement equipment, the EPM7128STC100-7 implements front-panel scan matrix control, trigger conditioning, and counter prescalers that need fast deterministic response. The 7.5 ns tPD keeps trigger latency well below the instrument's measurement uncertainty, and the 84 I/Os scan 7-segment displays, rotary encoders, and 4x4 matrix keypads simultaneously. The 5V I/O is ideal for legacy backplanes, and JTAG ISP allows firmware upgrades without opening the enclosure. Engineers can prototype measurement algorithms in a familiar Quartus environment with no MCU firmware loop.

設計ノート
The EPM7128STC100-7 requires a clean 5V VCC rail on all VCC pins (1, 14, 31, 47, 63, 79, 95 in the TQFP-100 package). Estimated: at full toggle activity on all 84 I/Os with 25 pF loads at 50 MHz, ICC can reach approximately 300-400 mA. Place one 0.1uF ceramic decoupling capacitor adjacent to every VCC/GND pair, plus a single 10uF tantalum bulk capacitor near the package. Inrush during ISP programming can briefly draw 500 mA - ensure the regulator has adequate headroom.
Place all 7 VCC pins and 7 GND pins on a continuous power plane under the TQFP-100 footprint. Keep the JTAG header (TDI/TDO/TMS/TCK on pins 96-99) routed with 4 dedicated signal traces and a TCK pull-down to ground if not actively driven. Use a 100-ohm series terminator on TDO if the JTAG cable exceeds 100 mm. Maintain at least 5 mm clearance between TQFP-100 traces and adjacent connectors to simplify probe access during in-system programming.
Do not confuse the EPM7128STC100-7 (MAX 7000S, 5V core) with the EPM7128AETC100-7 (MAX 7000AE, 3.3V core); the AE variant requires a different core voltage and JTAG programming setup. Also, the pinout table in the Altera MAX 7000 datasheet includes dedicated global clock pins (GCLK1, GCLK2, GCLK3) and dedicated OE pins (OE1, OE2, OE3) that must be honored; treating them as regular I/Os prevents proper global clock routing. Refer to the pcbsync.com MAX 7000 series guide for the exact TQFP-100 pin assignment.
For high-speed designs above 50 MHz, route all user I/O signals on the top layer directly under the package fanout with controlled impedance (typically 50 ohm single-ended). Use via-stitching around the TQFP-100 ground pad to maintain a low-impedance return path; the exposed die-attach paddle is internally grounded. Avoid running high-slew signals (clocks, fast edges) parallel to JTAG traces for more than 25 mm to prevent crosstalk into the programming chain.
