MPN: EPM7128SQI100-10 ✗ Cuối đờiEPM7128SQI100-10 Tóm tắt
What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic device that combines the architectural simplicity of a PAL with the density and flexibility of an FPGA. CPLDs sit in the programmable logic hierarchy between simple SPLDs (single PAL/GAL arrays) and FPGAs (gate-array style SRAM-based devices). They use EEPROM or flash configuration cells, retain their configuration without external memory, and are typically used for glue logic, bus bridging, state-machine control, and address decoding in cost-sensitive industrial designs. The MAX 7000S family targets 5V tolerant interfaces and provides in-system programmability (ISP) via IEEE 1149.1 JTAG.
Key features of the EPM7128SQI100-10 include pin-to-pin delays of 10 ns, counter speeds up to 175.4 MHz, 100% TTL-compatible I/O, JTAG-compliant ISP, and an extended industrial temperature range. The device supports 5V core operation with multi-voltage I/O support, making it suitable as a bridge between legacy 5V logic and modern 3.3V peripherals. Built-in JTAG (IEEE 1149.1) boundary-scan support simplifies board-level test.
Architecturally, the MAX 7000S device uses Logic Array Blocks (LABs) of 16 macrocells each, interconnected via a programmable interconnect array (PIA). Each macrocell contains a programmable AND/OR/registered logic block with configurable flip-flop polarity, clock, clear, and preset controls, and an I/O control block with tri-state, open-drain, or registered output options. The EEPROM cell technology guarantees 100 reprogram/erase cycles minimum.
Typical applications include industrial control glue logic, bus interface bridging (e.g., PCI to local bus), address decoding and chip-select generation, state-machine controllers in motor drives, and 5V-to-3.3V level translation in legacy system upgrades. The 84 user I/Os make it well-suited for medium-density interface aggregation.
When designing with the EPM7128SQI100-10, ensure the 5V VCC supply is well-decoupled with 0.1uF and 10uF capacitors placed close to the device. Unused I/O pins should be configured as outputs and left unconnected, or tied to a defined logic level through the Quartus design software. Industrial-grade parts require proper thermal management at high toggle rates.

Ứng dụng tiêu biểu
EPM7128SQI100-10 phù hợp cho 6 Áp dụngs: Industrial Control Glue Logic, 5V to 3.3V Level Translation Bridge, Address Decoding and Chip-Select Generation, State-Machine Controller in Motor Drives, PCI / Local Bus Interface Bridge, Legacy System Refresh and Form-Fit-Function Replacement.
Industrial Control Glue Logic
The EPM7128SQI100-10 fits industrial control glue logic because of its 128 macrocells of EEPROM-based non-volatile logic with 10 ns deterministic pin-to-pin delay and industrial -40C to +85C operating range. In a typical PLC backplane, it aggregates discrete sensor inputs, generates chip-select signals, and provides timing/sequencing between the CPU and peripheral ASICs. Unlike microcontrollers, its deterministic 10 ns delay makes it ideal for real-time response without firmware overhead.
Được đề xuất
5V to 3.3V Level Translation Bridge
The EPM7128SQI100-10 is well-suited for 5V-to-3.3V level translation bridges in legacy system upgrades because of its multi-voltage I/O feature. Each I/O bank can be independently powered at 5V or 3.3V, allowing the CPLD to act as a bidirectional voltage-level buffer between legacy 5V peripherals and modern 3.3V processors. With 84 user I/Os and 10 ns propagation delay, it can bridge wide parallel buses without introducing meaningful latency.
Được đề xuất
Address Decoding and Chip-Select Generation
The EPM7128SQI100-10 is ideal for address decoding and chip-select generation in memory-mapped systems because of its combinational logic speed and JTAG-driven in-system reprogrammability. With 10 ns pin-to-pin delay, it generates fast chip-select signals for SRAM, DRAM, Flash, and peripheral ASICs in 68k, x86, or PowerPC-based embedded systems. Its EEPROM-based configuration allows late-stage board-revision updates without replacing the device.
Được đề xuất
State-Machine Controller in Motor Drives
The EPM7128SQI100-10 is well-matched to motor-drive state-machine controllers because its 128 macrocells and 84 I/Os can implement multi-state commutation, fault handling, and PWM enable sequencing for three-phase inverter stages. The 10 ns pin-to-pin delay provides deterministic response to overcurrent and position-sensor inputs faster than microcontroller interrupt latency. Industrial -40C to +85C operation handles under-hood thermal stress in traction and industrial drive applications.
Được đề xuất
PCI / Local Bus Interface Bridge
The EPM7128SQI100-10 functions as a PCI-to-local-bus bridge in embedded computing because of its 5V PCI signaling compatibility, 84 I/Os, and 10 ns timing margin for 33 MHz PCI bus operation. It implements the address/data multiplexing, command decoding, and target/master state machines required to attach legacy peripherals to a PCI host. Its non-volatile EEPROM configuration means no boot PROM is required.
Được đề xuất
Legacy System Refresh and Form-Fit-Function Replacement
The EPM7128SQI100-10 is the natural choice for legacy system refresh designs that must preserve PCB layout and firmware interfaces because it remains pin-compatible with the original MAX 7000S PQFP-100 footprint and JTAG programming flow. With 100 reprogram/erase cycles and industrial temperature range, it supports long-life field-deployed systems in medical, transportation, and aerospace where re-spinning the PCB is impractical. Designers can extend product life cycles without requiring firmware changes.

Ghi chú thiết kế
The EPM7128SQI100-10 requires a monotonic 5V VCC ramp during power-up per the MAX 7000S datasheet; VCC must rise without dips that could trigger spurious JTAG state transitions. Place a 0.1uF ceramic decoupling capacitor close to each VCC pin and a single 10uF bulk capacitor near the package. For multi-bank designs, ensure each I/O bank supply is powered up simultaneously with the core supply to avoid latch-up.
The PQFP-100 package has 0.65 mm pitch leads that require careful PCB layout to avoid solder bridging during reflow. Use a solder paste stencil of 0.15 mm thickness and follow IPC-7351 land pattern guidelines for PQFP packages. Route high-speed outputs (clocks, PCI bus signals) on the top layer with a continuous ground reference plane beneath to control impedance and minimize crosstalk into adjacent I/O pins.
Inputs may undershoot to -2.0V for periods shorter than 20 ns during high-speed transitions - this is permitted by the datasheet but requires series-damping or clamping if driving from long PCB traces. Outputs should be configured with appropriate slew-rate control (slow slew rate option) for bus signals above 33 MHz to limit EMI and ground bounce on the PQFP-100 lead frame.
Do not assume modern Quartus software supports the MAX 7000S family - the legacy MAX+PLUS II toolchain (or Quartus versions prior to 13.0) is required for design compilation. Programming files (.pof) generated for newer Altera/Intel CPLDs are NOT compatible with the EPM7128SQI100-10. Also, verify the JTAG chain order matches the BSDL file when the device shares a JTAG bus with other components.
