A CPLD is a non-volatile, instantaneously-on programmable logic device that implements glue logic, bus decoding, state machines, and interface bridging between disparate voltage or timing domains. In the broader programmable-logic taxonomy, CPLDs sit alongside SRAM-based FPGAs and antifuse FPGAs; they are characterized by deterministic timing, low static power, and an EEPROM-based configuration cell that retains the bitstream without an external boot PROM. The EPM7128STC100-15N belongs to the MAX 7000S sub-family, which adds in-system programmability (ISP) via the IEEE 1149.1 JTAG interface to the original MAX 7000 architecture.
Key features of the EPM7128STC100-15N include 128 macro cells grouped into 8 Logic Array Blocks (LABs) of 16 macro cells each, a programmable interconnect array (PIA), and per-pin selectable open-drain or totem-pole outputs. The device also offers user-configurable macro cell flip-flops, four dedicated inputs that feed all macro cells for fast global clocking, and a global clear and global clock network. Each I/O pin is compatible with 5 V, 3.3 V, and 2.5 V logic levels through programmable voltage-clamp circuitry.
The MAX 7000S architecture separates logic from interconnect, providing predictable -15 ns combinatorial propagation delays that do not vary with routing density. This determinism makes the part a strong choice for asynchronous glue logic, decoder/address-latch functions, and peripheral controllers where FPGAs would add unnecessary cost or boot latency. The on-chip EEPROM cell array typically supports 100 program/erase cycles and is programmed through the JTAG or ByteBlaster cable using Altera Quartus II or MAX+PLUS II development tools.
Typical applications include bus decoding and address mapping in embedded systems, I/O expansion for microcontrollers without native peripherals, peripheral glue logic between processors and memory, LED and seven-segment display multiplexing, and legacy industrial control where -40C to +85C operation and instant-on non-volatile configuration are required. Designers often choose this device as a pin-compatible upgrade from discrete 74LS/74HC glue logic when board real estate is constrained.
When designing with the EPM7128STC100-15N, observe the I/O voltage-clamp recommendations in the datasheet: each output should include a series resistor when driving 3.3 V logic to limit shoot-through current, and unused I/O pins must be configured as outputs driving ground to minimize power consumption. The 100-pin TQFP exposed-pad must be soldered to a thermal copper pour of at least 1 square inch for reliable -40C to +85C operation at full toggle frequency.

التطبيقات النموذجية

Microcontroller I/O Expansion and Bus Decoding
The EPM7128STC100-15N is a natural fit for microcontroller I/O expansion and bus decoding because its 128 macro cells and 84 user I/O pins can decode large address windows and generate multiple chip-select signals in a single device. The 15 ns pin-to-pin delay matches the timing budget of an 8-bit or 16-bit MCU running at 33 MHz, ensuring that the CPLD output settles within one clock period after the address bus changes. With 5 V VCCIO tolerance, the part can be interfaced directly to legacy 5 V peripherals without level-shifters, reducing BOM cost and board area. Designers typically implement address latch, chip-select decoding, and wait-state generation in one EPM7128, replacing multiple discrete 74LS138/74LS139 decoders and 74LS373 latches. The non-volatile EEPROM configuration boots in microseconds, so there is no FPGA-style configuration delay - critical for deterministic interrupt latency in motor-control or industrial-automation firmware.

Peripheral Glue Logic and Interface Bridging
The EPM7128STC100-15N's deterministic timing and 5 V I/O make it ideal for interface-bridging glue logic between processors, memory, and peripherals operating at different voltages. A common use case is bridging a 5 V MCU to a 3.3 V SD card or NOR flash, where the CPLD's programmable VCCIO bank can be split into one 5 V bank and one 3.3 V bank - eliminating external level-shifters. The 15 ns tPD adds only one extra clock of latency at 66 MHz, which is acceptable for SPI, I2C, or parallel-memory interfaces. The 84 user I/Os are sufficient to implement a full 16-bit address bus, 16-bit data bus, and 8-10 control signals in a single device, leaving macro cells available for handshake logic. Designers also appreciate that the JTAG ISP allows field-upgradeable firmware fixes without desoldering the part.

State Machine and Industrial Control Logic
For industrial control, the EPM7128STC100-15N's -15 ns delay, 76.9 MHz internal toggle rate, and EEPROM-based non-volatile configuration deliver the determinism and reliability required for safety-critical state machines. Each macro cell contains a flip-flop, so a single device can implement several independent FSMs such as a packaging-machine sequencer, conveyor controller, or HVAC state controller. The 5 V tolerant I/O interfaces directly to 24 V industrial sensors and actuators through external optocouplers, avoiding the level-shifting required by 3.3 V FPGAs. The MAX 7000S family's instant-on configuration (microseconds, not milliseconds) is critical for fail-safe startup where any boot delay could cause process malfunction. Programming via JTAG also lets engineers perform in-circuit firmware revisions without removing boards from production equipment.

LED Multiplexing and Display Driving
The EPM7128STC100-15N's 84 user I/Os are well-suited for driving large LED matrices, 7-segment displays, and character LCDs where many discrete signals must be time-multiplexed. A single EPM7128 can scan a 64-LED matrix, an 8-digit 7-segment display, or a 4-line character LCD without any additional drivers. The 76.9 MHz internal toggle rate ensures flicker-free refresh rates above 100 Hz even for large displays, while the 15 ns tPD ensures clean column-to-column transitions. The 5 V I/O can directly drive common-anode or common-cathode LED arrays without buffer transistors, reducing board complexity. Designers also use the JTAG ISP to change display patterns or timing parameters without re-spinning hardware - a major advantage for prototype and small-batch production.

Legacy 74LS / 74HC Logic Replacement
The EPM7128STC100-15N is frequently used to replace multiple discrete 74LS, 74HC, or 74HCT logic ICs on legacy PCBs where board area is constrained. A single EPM7128 can absorb up to 128 macro cells of glue logic - equivalent to 8-12 small-scale integration (SSI) packages - reducing both component count and assembly cost. The -15 ns tPD is comparable to a 74LS153 multiplexer or 74LS138 decoder, so existing timing margins are preserved. The 5 V VCCIO tolerance is pin-compatible with TTL and CMOS legacy logic rails, simplifying migration. This application is especially common in industrial and aerospace systems that must be re-spun to reduce obsolete-discrete-logic risk without redesigning the board footprint.

Instant-On Boot and Configuration Memory Replacement
The EPM7128STC100-15N's EEPROM-based configuration cell provides microsecond-class instant-on, which is faster than any SRAM-based FPGA boot PROM. Designers use this property for power-critical applications such as automotive body controllers, security panels, and emergency-stop controllers where any boot delay is unacceptable. The 128 macro cells are sufficient to implement both the boot logic and the steady-state functionality in one device, eliminating a separate configuration memory chip. The JTAG ISP supports in-the-field firmware updates, so the same hardware can be reprogrammed across product variants - a major simplification for low-volume, high-mix production. Per the Altera datasheet, the configuration EEPROM retains the bitstream indefinitely without power, supporting decades of shelf life.

ملاحظات التصميم
Estimated: at VCC = 5 V and all 84 I/Os toggling at 76.9 MHz into 50 pF loads, the EPM7128STC100-15N consumes approximately 250-400 mA of dynamic supply current plus 5-10 mA of static current. Designers should provide a 100 nF decoupling capacitor within 5 mm of each VCC pin (the 100-pin TQFP has multiple VCC pins distributed around the package). Per the Altera datasheet, unused I/O pins must be programmed as outputs driving ground to minimize switching current; leaving them floating can increase supply current by 30-50 mA.
Route all four JTAG signals (TCK, TMS, TDI, TDO) as a daisy-chain with 100 ohm series-termination resistors near the driving CPLD. Keep JTAG traces at least 3 mm away from clock traces to avoid coupling that can corrupt ISP programming. The exposed thermal pad of the 100-pin TQFP must be soldered to a copper pour of at least 1 square inch to keep junction temperature below 125 C at full toggle rate. Per the Altera datasheet, the VCCIO pins (5 V or 3.3 V) must be applied before VCC during power-up to prevent I/O latch-up.
Do not assume the EPM7128STC100-15N is in production - it was discontinued in June 2017 per the Altera PDN. Source from franchised distributors only (DigiKey, Mouser, Arrow) or from authorized secondary-market specialists. Verify that the JTAG chain order matches your schematic when chaining multiple EPM7xxx devices, because the MAX 7000S family uses a fixed 10-bit JTAG instruction register length. When migrating to MAX II / MAX V for new designs, plan for pinout differences and recompile all design files - the new families use a different BSDL boundary-scan description.
