EPM7128SQI100-10N Обзор
What is a CPLD? A Complex Programmable Logic Device is a non-volatile, reprogrammable digital IC that sits between simple PAL/GAL spld devices and high-density FPGAs. CPLDs (hierarchy: CPLD -> PLD -> programmable logic -> digital IC -> semiconductor) use a deterministic routing fabric and on-chip EEPROM/flash configuration memory, so they retain logic at power-up with no external boot PROM. The MAX 7000S family from Altera (now Intel FPGA) is a second-generation MAX architecture family widely used as glue logic, bus bridges, and state-machine controllers in industrial, telecom, and embedded designs.
Key features of the EPM7128SQI100-10N include 5-ns pin-to-pin delays (commercial speed grade), 100 MHz maximum operating frequency, IEEE Std. 1149.1 JTAG boundary-scan test (BST) circuitry, multiVolt I/O for 2.5 V / 3.3 V / 5 V interfacing, and individual macrocell clear/preset for synchronous or asynchronous control. The 'I' suffix indicates the industrial temperature grade (-40C to +85C), and the 'N' suffix indicates a lead-free / Pb-free RoHS-compliant assembly.
Architecturally, the EPM7128SQI100-10N organizes its 128 macrocells into four Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA). Each macrocell contains a programmable AND/OR array plus a configurable flip-flop with product-term clock, clear, and preset - giving designers 32 product terms per macrocell for sum-of-products logic. The deterministic PIA routing yields predictable, glitch-free timing that is independent of design placement - a key advantage over FPGAs for control-plane logic.
Typical applications include bus decoding and address mapping, peripheral chip-select generation, state-machine controllers, I/O expansion and bus bridging, glue logic between microprocessors and peripherals, and JTAG-controlled test access. The wide I/O count and PQFP-100 footprint make it well-suited for legacy industrial backplanes and 5 V-tolerant designs.
When designing with this device, ensure the VCCINT-to-VCCIO supply sequencing follows the datasheet monotonic-rise requirements and that unused I/O pins are correctly terminated (per AN 74). The JTAG chain should include the proper bypass instructions to avoid contention when multiple devices share TCK/TMS.

Типичное применение
EPM7128SQI100-10N подходит для 6 применениеs: Microprocessor Bus Decode and Chip-Select Generation, Glue Logic and Peripheral I/O Expansion, State-Machine and Control-Plane Logic, Legacy Industrial Backplane and 5 V System Design, JTAG-Based Board Test and Boundary-Scan, Communication Protocol Bridging (UART / SPI / I2C / Parallel).
Microprocessor Bus Decode and Chip-Select Generation
The EPM7128SQI100-10N is ideal for microprocessor / microcontroller bus decoding thanks to its 128 macrocells and 84 user I/Os, which comfortably handle 24- to 32-bit address decoding plus multiple active-low chip-select outputs. Its 10 ns pin-to-pin delay keeps address-to-CS latency well below one 33 MHz bus cycle (30 ns), enabling clean zero-wait-state interfacing to MCUs, DSPs, and memory banks. The deterministic PIA routing of the MAX 7000S family yields predictable, placement-independent timing - critical for chip-select logic where any added glitch could mis-trigger a peripheral. Industrial temperature grade and 5 V tolerant I/O let the same CPLD serve across factory, telecom, and embedded backplane designs.

Glue Logic and Peripheral I/O Expansion
When a microcontroller runs out of I/O pins or needs custom peripheral interfacing, the EPM7128SQI100-10N provides up to 84 user I/Os organized through four Logic Array Blocks, each with 16 macrocells. The CPLD's EEPROM-based configuration retains logic at power-up with no boot PROM required, simplifying board bring-up. With 10 ns tPD and 100 MHz fMAX, it can comfortably bridge slow peripherals to fast SPI, I2C, or UART busses, or generate PWM, quadrature decoding, and pulse-train outputs. The multiVolt I/O feature (2.5 V / 3.3 V / 5 V VCCIO) lets the same CPLD interface directly between modern low-voltage MCUs and legacy 5 V peripherals.
Рекомендуется
State-Machine and Control-Plane Logic
The deterministic interconnect of the MAX 7000S architecture makes the EPM7128SQI100-10N an excellent platform for complex state machines, sequencers, and protocol controllers. Each macrocell offers up to 32 product terms plus a programmable flip-flop with separate clear, preset, and clock-enable signals - sufficient capacity for FSMs with 16 to 32 states. The 100 MHz fMAX accommodates USB full-speed, CAN 1 Mbps, and 10/100 Ethernet MAC-side interfaces. Industrial temperature grade and JTAG boundary-scan (BST) support production board-test access on telecom and industrial-control boards.
Рекомендуется
Legacy Industrial Backplane and 5 V System Design
Many industrial backplanes, VME / cPCI cards, and factory-automation controllers are 5 V systems that require 5 V-tolerant CPLDs - a niche where the EPM7128SQI100-10N excels with its 5 V VCCINT and programmable VCCIO. The 100-pin PQFP package is widely supported on legacy backplane PCB layouts and can drive long bus traces through its 24 mA drive strength per pin. Industrial -40C to +85C operation and lead-free RoHS assembly make it compliant with current manufacturing standards while preserving the form, fit, and function of older designs.
Рекомендуется
JTAG-Based Board Test and Boundary-Scan
The MAX 7000S family integrates IEEE Std. 1149.1 JTAG boundary-scan test (BST) circuitry on every I/O pin, making the EPM7128SQI100-10N a natural boundary-scan hub for production board-test architectures. With 84 I/Os, it can monitor interconnect continuity across large BGA devices on the same board and drive TEST_MODE signals across the test fixture. Quartus II programmer and USB-Blaster cable provide in-system programming through the same JTAG chain, eliminating socketed programming and enabling field firmware updates. Industrial temp grade and lead-free assembly suit telecom and automotive test-floor equipment.
Рекомендуется
Communication Protocol Bridging (UART / SPI / I2C / Parallel)
The EPM7128SQI100-10N is frequently used as a bridge between mismatched communication interfaces - for example, converting a 16-bit parallel camera bus to SPI, or splitting a UART stream across multiple peripherals. Its 128 macrocells provide enough logic capacity to implement full-duplex UART with FIFO buffering, SPI master/slave with multi-CS, and I2C master state machines simultaneously. The 100 MHz fMAX and 10 ns tPD keep bit-rate latency low even at 10 Mbps SPI. The PQFP-100 footprint offers 84 user I/Os, enough to expose four independent serial channels and parallel control lines.

Заметки по проектированию
VCCINT must be a monotonic 5.0 V rise per the MAX 7000 datasheet Operating Requirements - any voltage dip during power-up can place the device into an undefined state and risk EEPROM configuration corruption. Use a supervisor IC (e.g., MAX811) or a well-bypassed 5 V LDO with at least 100 mA headroom. Place 0.1 uF ceramic decoupling on every VCCINT pin and a bulk 10 uF tantalum close to the PQFP-100 package. VCCIO can be tied to 2.5 V, 3.3 V, or 5 V independently; never leave it floating.
Route TCK and TMS away from high-frequency switching nets to avoid JTAG programming errors. Place the JTAG header within 50 mm of the CPLD pins to keep the TCK rise time clean and avoid signal-integrity issues on long stubs. Maintain at least 4 vias worth of thermal copper under the PQFP-100 thermal pad (exposed die-attach paddle) to keep junction temperature below 125 C at industrial ambient (Estimated: 1 W typical dissipation in MAX 7000S, theta_JA approximately 35 C/W in still air).
Do not assume any I/O pin can drive a 24 mA load without checking the VCCIO setting - high DC sink current at 5 V VCCIO with all outputs simultaneously asserted can exceed package power dissipation. Limit concurrent high-current outputs to 16-20 pins and derate for ambient > 50 C. Also, when migrating a programmed design from EPM7128SQI100-10 (leaded) to EPM7128SQI100-10N (lead-free), confirm the JTAG chain order and IDCODE match before field deployment - same die, but different device ID may report a different silicon revision.
Информация о соответствии
The 'N' suffix denotes lead-free matte-tin plating and RoHS compliance. Halogen-free status is not explicitly stated in the verified data and is marked unknown. AEC-Q100 is not applicable - this is a commercial / industrial CPLD, not an automotive-qualified part.
