Typical Applications
EPM570F256C4N is suitable for 6 applications: I/O Expansion and Bus Bridging, Industrial Control Glue Logic, Power Sequencing and Reset Distribution, LED Display Scan and Driver Control, Communication Infrastructure Glue Logic, State Machine Controllers and Protocol Engines.
I/O Expansion and Bus Bridging
The EPM570F256C4N's 160 user I/Os in a 256-ball FineLine BGA package make it a strong fit for I/O expansion and bus-bridging in industrial and embedded systems. With 570 logic elements and a 5.4 ns pin-to-pin delay, it can translate between legacy 5V-tolerant buses and modern 1.8V/2.5V/3.3V microprocessors using its MultiVolt I/O ring without external level shifters. Place the CPLD between a host MCU's GPIO bank and a parallel peripheral bus; the instant-on non-volatile flash configuration means bridge logic is alive within 1 ms of power-up, critical for systems requiring deterministic boot sequencing. The 256-FBGA also provides ample I/O headroom for adding extra peripheral channels beyond the MCU's native count.
Recommended
Industrial Control Glue Logic
In industrial PLC and motor-control designs, the EPM570F256C4N consolidates scattered 74-series glue logic into a single non-volatile CPLD, reducing PCB area and improving reliability. Its 0.18 µm flash process tolerates industrial vibration and thermal cycling, and the 256-FBGA package's 17 × 17 mm footprint suits compact DIN-rail modules. The 304 MHz internal frequency and 5.4 ns tPD handle encoder quadrature decoding, PWM fanout, and reset distribution in real time without jitter. The 8-Kbit UFM stores device serial numbers and calibration constants, eliminating an external EEPROM and its associated I2C/SPI bus traffic.
Recommended
Power Sequencing and Reset Distribution
The EPM570F256C4N's instant-on flash configuration makes it ideal for multi-rail power-sequencing and reset-distribution tasks in servers, networking switches, and FPGA-SoC systems. Because the CPLD wakes in < 1 ms with all 160 I/Os functional, it can drive enable signals to downstream DC-DC converters and assert reset lines to ASICs before an SRAM-based FPGA has even loaded its configuration bitstream. The 5.4 ns tPD enables tight sequencing windows, while MultiVolt I/O allows the same CPLD to interface 1.8V, 2.5V, and 3.3V rails without glue logic. The 8-Kbit UFM can store brown-out threshold parameters for adaptive reset behavior.
Recommended
LED Display Scan and Driver Control
LED video walls, stadium displays, and large-format signage benefit from the EPM570F256C4N's combination of 160 I/Os and deterministic 5.4 ns tPD. The CPLD can scan-row multiplex large LED arrays, generate PWM grayscale modulation, and perform gamma correction with timing accuracy that software bit-banging cannot match. The 256-FBGA's high I/O count supports direct drive of 16-32 bit parallel data buses to LED driver chips without external latches. MultiVolt I/O compatibility means the same design can interface both 5V legacy and 3.3V modern LED driver ICs.
Recommended
Communication Infrastructure Glue Logic
In telecom and networking hardware, the EPM570F256C4N serves as low-cost glue logic for backplane bridging, clock distribution, and front-panel I/O aggregation. Its 304 MHz internal frequency handles LVDS-style clock buffering and protocol adaptation between line cards and switch fabrics. The 160 I/Os support 8-10 bit parallel datapaths commonly used in serializer/deserializer (SerDes) companion logic. Non-volatile instant-on configuration ensures the CPLD is alive before the host ASIC completes its PCIe link-training sequence, eliminating race conditions during system bring-up. The 256-FBGA package is footprint-compatible with EPM1270 and EPM2210, allowing a single PCB to scale with design complexity.
Recommended
State Machine Controllers and Protocol Engines
The EPM570F256C4N implements custom state machines and simple protocol engines — UART bridges, SPI-to-I2C converters, SD card controllers, and motor step/direction sequencers — without an MCU. The 570 logic elements and 57 LABs provide ample capacity for 16-32 state FSMs with parallel datapath operations, and the 5.4 ns tPD supports bit-banged serial protocols up to 50 MHz. The 8-Kbit user flash memory can store protocol lookup tables or device descriptors, simplifying firmware upgrades. The 256-FBGA footprint is ideal for space-constrained designs that need both high logic density and 160 I/Os.

Design Notes
The EPM570F256C4N requires both 2.5 V or 3.3 V VCCINT (core) and a separate VCCIO bank supply. Decoupling must follow the MAX II pin connection guidelines: place one 0.1 µF ceramic capacitor adjacent to every VCCINT/VCCIO ball and a 10 µF bulk capacitor near the package. The MultiVolt I/O ring allows VCCIO to be 1.5 V, 1.8 V, 2.5 V, or 3.3 V independently from VCCINT, but unused I/O banks must still have VCCIO supplied to keep I/O buffers in a known state.
Estimated: at typical CPLD toggle activity (~30% I/O utilization, 100 MHz), the EPM570F256C4N in 256-ball FBGA dissipates approximately 0.5–1.0 W. The FineLine BGA has a θJA of approximately 20 °C/W on a 4-layer JEDEC PCB, yielding a junction-temperature rise of 10–20 °C above ambient — well within the 0 °C to +70 °C commercial range. Industrial-temperature variants (EPM570F256I5N) should follow the same thermal design but with extended headroom to -40 °C. No external heatsink is required for typical use.
BGA fanout must use the standard 1.0 mm pitch escape pattern with vias-in-pad recommended for the inner balls. Use a 4-layer stack-up with continuous GND plane directly under the BGA to provide low-inductance returns. JTAG chain signals (TDI/TDO/TMS/TCK) should be routed with 50 Ω controlled impedance and length-matched within 2 inches to avoid programming failures. The 256-FBGA footprint is footprint-compatible with EPM1270F256 and EPM2210F256 — use a single PCB layout to support all three density points via JTAG reprogramming.
Do not leave unused I/O pins floating — configure them as outputs driving '0' or as inputs with internal weak pull-up enabled via Quartus II pin assignment. Failing to supply VCCIO to unused banks triggers indeterminate I/O buffer behavior. The UFM block uses one specific block of flash that consumes ~1.2 mA additional ICCC during writes; ensure the regulator has adequate headroom if the UFM is rewritten at runtime. JTAG chain order matters: if the CPLD shares a JTAG chain with an FPGA or configuration device, ensure the chain order matches the programming file's BYPASS instruction length.
Compliance Information
