EPM7128STC100-10N 개요
What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic device that combines the instant-on characteristics of PAL/GAL architecture with macrocell-based logic blocks interconnected via a programmable AND/OR array. CPLDs sit in the programmable logic hierarchy below FPGAs but above simple PLDs, providing deterministic 10 ns-class timing, high I/O count, and unlimited in-system reprogrammability via JTAG. The MAX 7000S family uses Altera's second-generation MAX architecture with each macrocell containing a programmable AND array, a fixed-OR array, a flip-flop, and a product-term steering network.
Key features of the EPM7128STC100-10N include 128 macrocells organized into 8 Logic Array Blocks (LABs) of 16 macrocells each, 84 user I/O pins, in-system programmability through the IEEE 1149.1 JTAG interface, MultiVolt I/O supporting 2.5V/3.3V/5V interface levels, and built-in JTAG boundary-scan test support. The device also includes 4 dedicated input pins, a global clock network, and per-macrocell configurable registers that can be implemented as D, T, JK, or SR flip-flops. The non-volatile EEPROM-based configuration provides instant-on behavior with no external boot memory required.
The architecture is based on a CMOS EEPROM process with 5V-tolerant I/O cells. The MAX 7000S family is supported by Altera's legacy MAX+PLUS II and Quartus Prime design tools, with the Quartus II Web Edition providing a free development environment for this and other legacy MAX devices. Programmable Security Bits protect the design against unauthorized readback. The device supports both 3.3V and 5V JTAG in-system programming, with VCCIO pins enabling mixed-voltage I/O operation.
Typical applications include bus-interface bridging (PCI to ISA, microcontroller to peripheral glue logic), state-machine controllers, address decoding and chip-select generation, power-supply sequencing logic, communication protocol conversion (UART, SPI, I2C bridging), industrial control replacement of discrete 74-series logic, and high-speed bus arbitration. The 100-pin TQFP footprint is also suitable for legacy industrial designs where instant-on, deterministic timing is required.
When designing with the EPM7128STC100-10N, observe the VCCINT and VCCIO decoupling guidelines: place one 0.1 µF ceramic capacitor per power pin within 3 mm of each pin, plus a 10 µF bulk capacitor near the device. The JTAG pins (TCK, TMS, TDI, TDO, and optional TRST) require careful routing and a 10 kΩ pull-up on TCK per IEEE 1149.1 recommendations. Unused I/O pins can be left floating, but configured-as-input pins should be tied to a defined logic level through internal pull-ups or external resistors to avoid quiescent Icc drift.

일반적인 애플리케이션
EPM7128STC100-10N 적합 용도: 7 애플리케이션s: PCI-to-ISA Bus Bridge, Microcontroller Glue Logic, Industrial Control State Machines, Communication Protocol Converter, Power Supply Sequencing Logic, Address Decoding and Chip-Select Generation, Legacy 74-Series Logic Replacement.
PCI-to-ISA Bus Bridge
The EPM7128STC100-10N is well-suited as a PCI-to-ISA bus bridge controller because its 84 user I/Os can accommodate the 49 PCI signals plus 53 ISA signals after de-multiplexing, while its 10 ns tPD easily meets the 33 MHz PCI clock-to-out timing (tVAL 11 ns max). The 128 macrocells provide ample capacity for address decoding, command decoding, and interrupt steering logic between the two buses. Non-volatile EEPROM-based configuration ensures the bridge is active at power-on with no boot delay, critical for system BIOS hand-off during POST. MultiVolt I/O allows the 5V PCI signals and 5V ISA bus to share the same device with no external level shifters, reducing BOM cost and board area.
추천
Microcontroller Glue Logic
Use the EPM7128STC100-10N to consolidate discrete 74-series glue logic around a microcontroller, replacing 5-15 individual 74HC/74AHC packages with a single programmable device. The 128 macrocells and 84 I/Os provide generous capacity for address latch generation, chip-select decoding, interrupt encoding, wait-state insertion, and bus multiplexing between an 8-bit or 16-bit MCU and external peripherals. The 10 ns propagation delay ensures the CPLD does not become the limiting factor in the timing budget for buses up to 50 MHz, and JTAG-based in-system programmability allows last-minute pin reassignment without PCB rework.
추천
Industrial Control State Machines
Deploy the EPM7128STC100-10N as a deterministic state-machine controller for industrial automation lines, where its non-volatile configuration and instant-on behavior eliminate the boot-time uncertainty of FPGAs or processor-based controllers. The 128 macrocells support Mealy or Moore machines with up to 16-20 states plus output combinational logic, while 84 I/Os can drive sensor inputs, solenoid drivers, and HMI displays simultaneously. The commercial 0-70C temperature range suits factory-floor enclosures, and the JTAG interface enables on-line reprogramming for firmware updates without removing the PCB from the control cabinet. Hardened against single-event upset compared to SRAM-based logic, the EEPROM cells are immune to voltage glitches during power sequencing.
추천
Communication Protocol Converter
Implement UART-to-SPI, SPI-to-I2C, or RS-232-to-RS-485 protocol converters using the EPM7128STC100-10N, leveraging its bidirectional I/O cells to interface both sides of the conversion without external transceivers. The 128 macrocells fit a complete UART (start/stop bit handling, baud-rate generator, FIFO-like state machine) plus an SPI master/slave controller in a single device, while the 10 ns tPD supports SPI clock rates up to 50 MHz. MultiVolt I/O allows the converter to bridge 5V legacy UART lines with 3.3V modern MCUs directly, eliminating level-shifters in mixed-voltage designs.
추천
Power Supply Sequencing Logic
Use the EPM7128STC100-10N to sequence multiple power rails in a complex system (e.g., 1.2V core, 1.8V DDR, 3.3V I/O, 5V analog) by monitoring PG (Power Good) signals and asserting enable pins in the correct order with programmable delay. The 128 macrocells support a sequencing engine handling 8-16 rails with adjustable rise times, while the 84 I/Os provide PG inputs plus EN outputs plus status LEDs. The 5V-tolerant inputs interface directly with most supervisor ICs, and the deterministic 10 ns delay enables precise rail-to-rail timing alignment. The non-volatile configuration preserves the sequencing program through power cycles and brown-out events.
추천
Address Decoding and Chip-Select Generation
Generate chip-select signals for memory banks, peripheral devices, and I/O expanders from a single EPM7128STC100-10N, replacing 4-8 discrete 74HC138/74HC139 decoders with one programmable device. The 128 macrocells implement 16-32 independent chip-select decoders with programmable address ranges, chip-enable polarity, and output drive characteristics. With 10 ns tPD, the chip-select signals arrive within one clock cycle of address valid, supporting microprocessors and microcontrollers up to 50 MHz without wait-state insertion. JTAG in-system programming allows design changes to the memory map without PCB rework.
추천
Legacy 74-Series Logic Replacement
Replace obsolete or hard-to-source 74LS/74HC/74F-series discrete logic packages with a single EPM7128STC100-10N, consolidating what would otherwise require 8-15 DIP/SOIC packages into one TQFP-100 surface-mount device. This dramatically reduces PCB area, eliminates multi-vendor sourcing issues for legacy logic, and provides documented timing via the CPLD's datasheet instead of relying on per-family timing parameters. The 84 user I/Os map directly to standard 74-series pin groupings, and JTAG programming lets you re-implement the logic as design needs evolve without respinning the PCB.

설계 노트
Decouple VCCINT (5V) and VCCIO (3.3V or 5V) separately with one 0.1 µF ceramic capacitor within 3 mm of each power pin, plus a 10 µF bulk tantalum or ceramic capacitor near the device. The MAX 7000S family draws approximately 50-150 mA ICCINT at 100 MHz depending on utilization; use a regulator with at least 250 mA headroom. VCCIO must be stable before or simultaneously with VCCINT to prevent latch-up - sequence with a supervisor or use a common rail with adequate RC delay. Estimated: Icc scales linearly with fMAX and approximately quadratically with toggle rate; measure in-circuit to verify.
Route JTAG signals (TDI, TMS, TCK, TDO) as a daisy-chain with 10 kΩ pull-up on TCK and TMS, and 10 kΩ pull-up on TDI per IEEE 1149.1. Keep JTAG traces under 150 mm and away from clock signals. The TQFP-100 has a 0.5 mm pitch - use 0.15 mm trace/space design rules and micro-vias if HDI is available. Exposed-pad variants are not used on this package; standard 100-pin TQFP does not require a thermal pad.
Configure VCCIO bank-by-bank to match the I/O voltage of the connected bus (3.3V or 5V); mixing voltages within a single bank is not supported. Unused I/O pins should be configured as outputs driving low or as inputs with internal pull-ups enabled to avoid floating-pin Icc drift. For high-speed outputs (>50 MHz), use a series damping resistor (22-33 ohm) close to the CPLD pin to dampen transmission-line ringing on long traces.
Do not apply JTAG signals before VCCINT and VCCIO have stabilized, or the device may enter an undefined state. The MAX 7000S is 5V-tolerant on inputs but VCCIO must be present for the I/O cells to function correctly. Do not assume compatibility with MAX 3000A or MAX II pinouts - they are different packages with different power pins. When migrating from non-N to N suffix, verify the reflow profile (peak 260C for N variant vs 240C for SnPb) - high peak temperatures may damage the Pb-free matte-tin finish or warp the TQFP body.
