Typical Applications
EPM570F256C5N is suitable for 6 applications: Industrial Control I/O Expansion, Bus Multiplexing and Address Decoding, Power Sequencing and Reset Management, Legacy Peripheral Bridging, Display and LED Matrix Driving, Communication Protocol Conversion.
Industrial Control I/O Expansion
The EPM570F256C5N's 160 user I/Os and 570 logic elements make it well suited to industrial PLCs and controller boards that need to add GPIOs, encoder inputs, or PWM outputs beyond what the host MCU provides. Its instant-on, non-volatile flash configuration guarantees the I/O map is valid at power-up with no boot delay, critical for safety-critical and deterministic industrial applications. The 5.4 ns tPD and 304 MHz fMAX support high-speed encoder feedback and fieldbus glue logic without timing-closure headaches. MultiVolt I/O (1.5V to 3.3V) lets the same CPLD bridge 3.3V MCUs to 1.8V sensors directly. The 256-FBGA package keeps the design compact while exposing enough balls for wide I/O banks. Pair it with an STM32 host MCU and an isolated RS-485 transceiver to build a robust industrial node.
Recommended
Bus Multiplexing and Address Decoding
The EPM570F256C5N excels at address decoding and bus multiplexing for legacy peripherals in embedded designs. With 440 macrocells and 5.4 ns propagation delay, it can decode chip-select signals, multiplex address/data buses, and arbitrate DMA requests without adding latency to the system bus. The non-volatile flash configuration eliminates the boot PROM typically required by SRAM-based FPGAs, reducing BOM cost and PCB area. Industrial temperature variants are available for harsh environments. The Quartus II toolchain supports schematic and VHDL/Verilog entry, making it easy to retrofit legacy designs. Engineers commonly use this CPLD to bridge an 8-bit MCU to a 16-bit peripheral, or to fan out a single SPI bus to multiple slaves with individual chip-select lines.
Recommended
Power Sequencing and Reset Management
Power-up sequencing is a classic application for the EPM570F256C5N, where multiple voltage rails must come up in a specific order to satisfy processor or ASIC requirements. The device's instant-on flash configuration executes within microseconds of VCC ramp, enabling precise timing control of enable lines to DC-DC converters and LDOs. With 5.4 ns tPD, sequencing edges can be aligned to within a few nanoseconds, and watchdog or fault signals can be combined to drive a global reset. The MultiVolt I/O banks allow direct interface to 1.8V, 2.5V, and 3.3V rails without external level shifters. The 160 I/Os easily handle large multi-rail boards with sequenced power trees. A common pattern is to monitor PGOOD from each regulator and use the CPLD to gate downstream enables only after all upstream rails are valid.
Recommended
Legacy Peripheral Bridging
The EPM570F256C5N is widely used to bridge modern processors to legacy parallel-bus peripherals such as ISA, SRAM, or FPGA configuration memories. Its 5.4 ns tPD and 304 MHz fMAX easily meet ISA bus timing, while its 160 I/Os provide enough headroom for 16-bit data buses plus full address and control signal fan-out. The instant-on flash configuration means no boot PROM is needed, simplifying the bill of materials. Quartus II supports legacy IP cores and timing-constraint entry, allowing engineers to drop in glue logic without writing RTL from scratch. Industrial temperature variants are available for harsh-environment installations. A typical use is interfacing a modern ARM Cortex-A processor to an existing 8-bit ISA peripheral card with no driver changes.
Recommended
Display and LED Matrix Driving
The EPM570F256C5N's high I/O count and deterministic timing make it an excellent choice for driving large LED matrices, character LCDs, and small TFT displays. With 160 outputs, it can refresh an 8x8 RGB LED cube or multiplex a 16-digit 7-segment display directly, with refresh rates well above 60 Hz to avoid flicker. The 5.4 ns tPD enables fast multiplexing without ghosting, and the flash-based configuration eliminates the boot latency common with SRAM-based controllers. MultiVolt I/O simplifies interface to 3.3V or 5V LED drivers. The instant-on behavior ensures the display is correct immediately after power-up, which is critical for user-facing products. Engineers commonly pair this CPLD with constant-current LED drivers like the TLC5941 to build large signage panels.
Recommended
Communication Protocol Conversion
The EPM570F256C5N is frequently used as a low-latency protocol converter between SPI, I2C, UART, and parallel interfaces in embedded systems. With 440 macrocells, it can implement full hardware state machines for protocol translation without burdening the host MCU. The 304 MHz fMAX supports high-speed SPI (>50 MHz) and even simple custom bit-banged protocols. MultiVolt I/O allows direct bridging between 1.8V and 3.3V domains without external level shifters. The flash-based configuration means the converter is ready within microseconds of power-up, eliminating USB-enumeration or boot-delay problems. Industrial temperature variants suit factory-floor protocol gateways. Typical use: bridging an SPI sensor to an I2C host MCU with timing-controlled chip-select and interrupt signaling.

Design Notes
The EPM570F256C5N requires a clean 2.5V or 3.3V core supply. Decouple VCCINT and VCCIO pins with 0.1uF ceramic capacitors placed within 5 mm of each supply ball group; add a 10uF bulk tantalum or ceramic at the supply entry point. The MultiVolt I/O banks allow independent VCCIO rails per bank (1.5V, 1.8V, 2.5V, or 3.3V), so each bank must be decoupled separately. Tie all unused I/O pins to logic-low or logic-high via the Quartus II default pin configuration to minimize power and noise.
The 256-FBGA package has a 1.0 mm ball pitch and requires a 4- or 6-layer PCB with microvia technology for fan-out. Use a symmetrical stack-up with continuous ground planes under the BGA to provide a low-impedance return path and thermal spreading. Match trace lengths within each I/O bank to within 25 mils if you intend to use the CPLD for DDR or source-synchronous interfaces. Route JTAG signals (TCK, TMS, TDI, TDO) with 4-mil traces and guard them with ground vias to avoid programming failures.
Although MAX II CPLDs are low-power devices, sustained switching of all 160 I/Os at 304 MHz can produce 0.5W to 1W of dissipation. The 256-FBGA package relies on PCB copper for heatsinking - place a thermal via array under the center ground balls and stitch the top ground pour to inner ground planes with 0.3 mm vias on a 1.2 mm grid. Estimated: theta_JA on a standard JEDEC 4-layer test board is approximately 25 C/W, so 1W of dissipation yields a 25C junction temperature rise. Industrial variants (EPM570F256I5N) must respect the wider -40C to 100C ambient range.
Do not mix JTAG TCK frequencies above 10 MHz without verifying signal integrity; ringing on long JTAG chains can cause programming failures. Always assert nCONFIG high and wait for nSTATUS to return high before starting JTAG operations. Do not leave VCCIO banks floating - the device may draw excess current or fail to configure. When migrating from C5 to C4/C3 speed grades, re-run Quartus II timing analysis because the slower tPD may violate existing setup/hold margins.
Place the JTAG header or USB-Blaster connector within 50 mm of the CPLD to minimize noise pickup on TCK and TMS. Add a 4.7k pull-up to TDI and a 4.7k pull-up to nCONFIG if the JTAG interface is shared with multiple devices. Reserve a dedicated GND test point near the BGA for scope-probe grounding during bring-up. For high-speed signals (>50 MHz), use microstrip routing with controlled impedance (50 ohm single-ended, 90 ohm differential) and keep stub lengths below 5 mm.
Compliance Information
