Typical Applications
EPM7256AETC100-5C is suitable for 6 applications: PCI-to-ISA Bus Bridge, Microcontroller Address Decoder, DSP Peripheral Glue Logic, Networking Line-Card Glue Logic, Industrial Automation State Machine, LED Display Driver Controller.
PCI-to-ISA Bus Bridge
The EPM7256AETC100-5C's 256 macrocells and 84 user I/O are well-matched to PCI-to-ISA bridge designs that must decode 32-bit PCI address/data plus 24-bit ISA bus signals. The 5 ns propagation delay provides two PCI clock cycles of decode margin at 33 MHz, comfortably meeting the 11 ns setup time required by most PCI peripherals. With MultiVolt I/O supporting 5 V ISA and 3.3 V PCI on the same die, no external level-shifters are required - the device bridges the two buses directly while consuming approximately 50 mA typical ICC at 33 MHz. Place the CPLD between the PCI connector and ISA edge-finger pins, route all 32 PCI signals through dedicated input pins, and use the macrocell registers for bus-cycle state machines. The 200 MHz counter frequency also supports high-speed bus-arbitration logic.
Recommended
Microcontroller Address Decoder
With 256 macrocells and 5 ns tPD, the EPM7256AETC100-5C decodes a full 24-bit microcontroller address bus and generates chip-selects for up to 16 peripherals in a single device. The deterministic 5 ns delay means chip-select assertion occurs within one 50 MHz microcontroller clock cycle, eliminating wait-states for most peripheral interfaces. Programmable power-saving modes reduce I/O current by 50% in idle decode states, important for battery-backed industrial controllers. Configure each macrocell as a wide AND-OR decode term, then register the output for clean synchronous chip-select generation. The on-chip EEPROM retains the decode map through power cycles, eliminating external PROM.
Recommended
DSP Peripheral Glue Logic
The EPM7256AETC100-5C serves as the ideal companion CPLD to DSP processors (TMS320, ADSP-21xx) requiring high-speed peripheral expansion. Its 200 MHz counter frequency generates DMA control signals, frame-sync timing, and interrupt-acknowledge arbitration at full DSP clock rates. The 84 I/O pins handle 16-bit memory buses plus 8-channel DMA handshake logic, with the remaining I/O available for codec and DAC control signals. MultiVolt I/O directly interfaces legacy 5 V peripherals to modern 3.3 V DSPs, eliminating level-shifter ICs from the BOM. The 5 ns pin-to-pin delay also meets timing margins for high-speed serial-port expansion logic.
Recommended
Networking Line-Card Glue Logic
In telecom line cards, the EPM7256AETC100-5C provides the bus-interface and timing-control glue between network processors, framers, and PHY devices. Its 256 macrocells implement full T1/E1 framer backplane interfaces, MDIO control for PHY management, and ATM SAR-side bus steering - all within deterministic 5 ns timing. The MultiVolt I/O interfaces 5 V legacy framers and 3.3 V PHY devices without external translators, reducing board area. The 84 user I/O count supports 8-bit UTOPIA/POS-PHY bus interfaces plus interrupt-aggregation logic. Industrial temperature variants handle outside-plant deployments where ambient temperatures vary widely.
Recommended
Industrial Automation State Machine
The EPM7256AETC100-5C implements deterministic FSMs for industrial motor controllers, PLC I/O expansion, and safety-interlock logic where predictable microsecond response is critical. The 5 ns tPD yields sub-microsecond reaction time to fault inputs - critical for Category-3/4 safety circuits. JTAG boundary-scan allows in-system verification of all 84 I/O pins during manufacturing test, reducing production test cost. With 256 macrocells, a single device replaces 8-12 discrete 22V10 PALs typically used in legacy motor-drive designs, simplifying BOM and reducing PCB area by 60%. The on-chip EEPROM retains state-machine configuration through power cycles without external storage.
Recommended
LED Display Driver Controller
For large LED video walls and signage displays, the EPM7256AETC100-5C drives row/column decoders and PWM brightness control with precise timing. Its 200 MHz counter frequency supports 16-bit PWM at 3 kHz refresh rate without external timing ICs. The 84 user I/O drive 8-bit row plus 8-bit column data simultaneously with row-strobe control, while remaining I/O handle brightness/multiplexing logic. MultiVolt I/O directly drives 5 V LED-driver buffers from a 3.3 V logic core. The 5 ns tPD supports high-speed multiplexing without flicker artifacts. On-chip EEPROM allows field-upgrade of display patterns and refresh algorithms without replacing the controller board.

Key Differentiators
- Fastest speed grade in the EPM7256AE family at TQFP-100 (vs EPM7256AETC100-10)
- Commercial temperature grade for cost-optimized deployments (vs EPM7256AETC100-5N)
- MultiVolt I/O eliminates external level-shifters (vs EPM7160SLC84-10)
Design Notes
The EPM7256AETC100-5C requires both VCCINT (3.3 V core) and VCCIO (2.5 V, 3.3 V, or 5 V I/O) supplies. Per the Altera MAX 7000A datasheet, decouple each VCCINT pin with a 0.1 Β΅F ceramic capacitor placed within 5 mm of the pin, and each VCCIO with a 0.1 Β΅F plus 10 Β΅F bulk capacitor. Estimated: at 200 MHz toggling of all 84 I/O pins at 50% activity, ICCINT rises to approximately 80-120 mA typical; design the 3.3 V regulator for at least 200 mA headroom. MultiVolt I/O allows VCCIO at 5 V while VCCINT remains at 3.3 V, simplifying mixed-voltage designs.
For JTAG in-system programming, the TCK pin requires a 10 kΞ© pull-up resistor to VCCIO. Route TCK as a short, impedance-controlled trace to avoid programming failures. Per the MAX 7000A datasheet, place the JTAG connector within 50 mm of the device for reliable ISP at high TCK frequencies. Keep JTAG signals away from high-frequency switching nets and noisy power planes. Use a four-layer PCB with dedicated ground plane beneath the TQFP-100 footprint to minimize ground bounce and signal-integrity issues on the 84 I/O pins.
Do not confuse the EPM7256AETC100-5C (commercial temp, 5 ns) with the EPM7256AETC100-10 (commercial temp, 10 ns) - the parts are pin-compatible but timing analysis differs. Avoid using obsolete 5 V-only MAX 7000 (non-A) variants with this device, as their I/O banks are not MultiVolt compatible. Per the Altera MAX 7000A datasheet, ensure unused I/O pins are configured as outputs driving ground to minimize quiescent current. Note that the EPM7256AETC100-5C is non-RoHS (Pb-bearing TQFP package); for RoHS-compliant designs, consider MAX II or MAX V CPLDs instead.
