EPM7128BTC100-10 Visão geral
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between small glue-logic PALs/GALs and larger FPGAs in the programmable logic hierarchy. It uses a classic EEPROM/Flash-based architecture with continuous, deterministic routing that delivers predictable timing regardless of logic placement. Compared with SRAM-based FPGAs, CPLDs boot instantly without an external configuration flash and retain configuration through power cycles, making them ideal for bus-interface bridging, power-sequencing, and control-plane glue logic.
The EPM7128BTC100-10 provides 128 macrocells grouped into 8 Logic Array Blocks (LABs) of 16 macrocells each, with each macrocell containing a programmable AND/OR array, a flip-flop, and product-term sharing for efficient state-machine implementation. The I/O structure is 3.3V-tolerant with 5V tolerant inputs (multiVolt interface), enabling direct interfacing with 3.3V, 2.5V, and 5V mixed-voltage systems. Programmable interconnect uses the FastTrack continuous routing matrix to deliver consistent 10ns tPD and 125 MHz fCNT performance.
Typical applications include bus-interface bridging, peripheral I/O expansion, address decoding for microprocessors, state-machine control, and power-supply sequencing. The 100-pin TQFP footprint is widely used in legacy industrial and telecom designs that require deterministic timing without an external configuration PROM.
When designing with this device, ensure that the JTAG chain is properly terminated with TCK pull-down and TMS pull-up resistors per IEEE 1149.1. For 5V input tolerance on the user I/O banks, keep VCCIO at 3.3V while VCCINT runs at 2.5V, and observe the maximum I/O current limit of 25 mA per pin when driving LED or relay loads.

Aplicações típicas
EPM7128BTC100-10 é adequado para 6 aplicaçãos: Microprocessor Address Decoding and Glue Logic, PCI / ISA Bus Bridge and Peripheral Expansion, Power Supply Sequencing and Supervisor Logic, Industrial Control and Factory Automation, Legacy Telecom and Networking Backplane Glue Logic, State-Machine Control for Test & Measurement.
Microprocessor Address Decoding and Glue Logic
The EPM7128BTC100-10 is a classic choice for 8/16/32-bit microprocessor address decoding, chip-select generation, and bus-interface glue logic. With 128 macrocells and 84 user I/Os, it has ample capacity to replace 5 to 10 discrete 74LS/74HC decoder and latch ICs on a legacy 386/486/Pentium board while saving roughly 60 percent of the PCB area. The 10 ns tPD delivers deterministic propagation delay regardless of which macrocell is used, so address-to-chip-select timing stays within the CPU's tACC budget across all operating conditions. JTAG/ISP lets engineers iterate on the decoding map in-circuit, eliminating the PROM burn-and-swap cycle that discrete PALs required. In production designs the device is typically powered from a 3.3V rail with the VCCINT 2.5V generated by an LDO, and decoupling is 0.1 uF plus 10 uF bulk per the MAX 7000B reference schematic.
Recomendado
PCI / ISA Bus Bridge and Peripheral Expansion
The EPM7128BTC100-10 is widely deployed as a PCI or ISA peripheral bridge, mapping memory and I/O windows between a CPU bus and an FPGA, ASIC, or legacy peripheral. The 84 user I/Os in TQFP-100 give engineers enough pins to break out an entire 32-bit data bus plus 24-bit address plus 8 chip selects without external muxes. The 5V-tolerant inputs (with VCCIO at 3.3V) interface directly to PCI 5V signaling, eliminating the level shifters that a 3.3V-only CPLD would require. The deterministic 10 ns tPD is critical for meeting PCI's 7 ns setup-time budget at 33 MHz when one nano second of tCO from the CPLD is added. Designers also use the JTAG port to field-update the bridge map when adding new peripherals, an upgrade path not available with discrete 74-series logic.
Recomendado
Power Supply Sequencing and Supervisor Logic
The EPM7128BTC100-10 fits naturally into multi-rail ATX or telecom power-supply sequencers, where 5 to 10 power rails must power up in a specific order with programmable delays and PG (power-good) interlocking. Each macrocell can implement a state machine or delay timer, and the 84 I/Os comfortably handle the rail count plus PG feedback plus fault-flag outputs. Because the device is non-volatile EEPROM-based, sequencing state survives brown-outs and power-cycles, a feature FPGAs lack without an external configuration PROM. The 2.5V core and 3.3V I/O are compatible with modern POL (point-of-load) converters, while the 5V-tolerant inputs accept TTL-level PG signals from legacy supervisors. Estimated: typical quiescent power at room temperature is 250 mW with all macrocells toggling at 10 MHz.
Recomendado
Industrial Control and Factory Automation
The EPM7128BTC100-10 (commercial 0 to 70C) and its automotive-grade sibling EPM7128AETC100-10N (-40 to +125C) are commonly deployed in PLCs, motor controllers, and factory-automation backplanes where deterministic timing and high I/O count matter. The 84 I/Os accept 24V industrial signals through external optocouplers, while outputs drive 5V relay coils or 24V drivers via external transistors. The device's deterministic 10 ns tPD is critical for closed-loop control where the controller-to-actuator latency budget is 100 micro seconds end-to-end. Non-volatile configuration means PLC firmware revisions persist across factory power cycles without an external boot PROM. Estimated: at 70C ambient with 84 I/Os switching at 1 MHz, the device dissipates roughly 400 mW and requires 200 mm squared of copper pour on the top layer.
Recomendado
Legacy Telecom and Networking Backplane Glue Logic
The EPM7128BTC100-10 has been a workhorse in legacy telecom and networking equipment such as T1/E1 line cards, central-office switches, and backplane controllers. The TQFP-100 footprint exposes enough I/Os to drive an entire 8-bit datacom backplane plus HDLC framing logic plus LEDs and alarm outputs. The non-volatile EEPROM core ensures that the backplane configuration survives the brown-outs that occur during central-office battery plant transitions, eliminating the FPGA-style in-rush storm that can collapse the 48V battery bus. JTAG/ISP enables field re-provisioning when a new line-card type is added to the chassis. Estimated: in a 48-port line-card design the CPLD typically replaces 12 to 18 discrete 74FCT and 74ABT devices, cutting board area by roughly 50 percent.
Recomendado
State-Machine Control for Test & Measurement
The EPM7128BTC100-10 is well suited for instrument front-panel state machines in oscilloscopes, logic analyzers, and bench multimeters, where 32 to 128 logic equations drive rotary-encoder decoding, button debouncing, LCD muxing, and menu navigation. The deterministic tPD of 10 ns is more than adequate for human-perceptible UI timing (10 ms to 100 ms), and the EEPROM core retains the menu state through power cycles. The 84 I/Os comfortably break out a 4-line rotary encoder plus 16-key keypad plus 4x40 LCD plus 8 status LEDs plus UART debug port. JTAG lets the firmware team iterate on the menu flow without re-spinning the front-panel PCB. Designers typically pair the CPLD with a small microcontroller for the LCD bitmap rendering, splitting deterministic control-plane work from the processor's variable-latency update path.

Principais diferenciais
- Industry-standard 100-pin TQFP footprint shared across the entire MAX 7000B 128-macrocell family (vs Xilinx XC9572XL (100-pin TQFP/VQFP))
- MultiVolt interface for direct 5V/3.3V/2.5V mixed-voltage system integration (vs Lattice ispMACH 4000V (LC4128V))
- Deterministic 10 ns tPD independent of logic placement and routing density (vs SRAM-based low-density FPGA (e.g. Lattice iCE40))
Notas de projeto
The MAX 7000B family uses a split-rail supply: VCCINT must be 2.5V and VCCIO must be 3.3V, with both rails ramped monotonically within the datasheet's tRAMP specification. Power sequencing is not strictly required, but if VCCIO ramps before VCCINT the I/O drivers will draw elevated current through the ESD cells. Decoupling per the datasheet is one 0.1 uF X7R ceramic per VCCINT pin and per VCCIO pin, plus one 10 uF tantalum or ceramic bulk capacitor near each supply pin. Estimated: total supply current at 125 MHz toggle with all 84 I/Os active is approximately 100 mA on VCCINT and 25 mA on VCCIO.
TQFP-100 with 0.5 mm lead pitch requires a 4-layer PCB with a continuous ground plane under the device to provide both thermal spreading and a low-impedance return path for the high-speed I/O. Route the four JTAG pins (TCK, TMS, TDI, TDO) on the top layer away from clock edges, and place a 10 kohm pull-down on TCK and 10 kohm pull-up on TMS as recommended by IEEE 1149.1. The TDO output should be series-terminated with 33 ohm if the trace length to the next JTAG device exceeds 50 mm. Ground vias should be placed at each GND pin with thermal relief to the inner ground plane.
Three common pitfalls in MAX 7000B designs: (1) driving 5V TTL inputs into the device without verifying that the input pin is configured as 5V-tolerant in the Quartus pin planner; (2) exceeding the 25 mA per-pin DC output current limit when driving LED or relay loads directly, which causes long-term electromigration failure; (3) failing to enable the JTAG USERCODE instruction in the programming file, which prevents in-field identification of the programmed image. Designers should also avoid connecting unused I/O pins to long traces or antennas - configure them as output driving ground to reduce EMI susceptibility.
