EPM570F256C5NRR 概要
A CPLD (Complex Programmable Logic Device) is a non-volatile digital IC that combines AND/OR array logic with macro cells, used to implement glue logic, state machines, bus interfaces, and protocol bridges. MAX II sits in the broader hierarchy of programmable logic: PAL/GAL -> SPLD -> CPLD -> FPGA, with CPLDs chosen over FPGAs when designers need fast deterministic pin-to-pin timing, low static power, instant-on configuration, and small-to-moderate logic densities in the 32- to 1,000-LE range. The EPM570 specifically targets designs that need more headroom than entry-level MAX II Z (EPM240) variants while staying below the cost of a low-end FPGA.
Key differentiating features include 8.0 Kbytes of user flash memory (UFM) block, support for hot-socketing and JTAG (IEEE 1149.1) boundary-scan, 4 mA IOL drive, in-system programmability via JTAG, and a 0.18 µm flash-based process that allows 100% factory retention of the bitstream across power cycles. The dual-voltage core (2.5 V) and I/O (2.5 V/3.3 V) rails let the device bridge 3.3 V peripherals to 2.5 V controllers without external level shifters on every bus.
Architecturally, MAX II uses a Logic Array Block (LAB) topology of 16 macro cells each, interconnected by a FastTrack Continuous Interconnect Matrix (CIM) that delivers predictable ~8 ns timing regardless of placement. The C5 speed grade is the commercial-temperature variant, suitable for 0 °C to +85 °C operation; an 'I' speed-grade variant exists for industrial -40 °C to +100 °C designs.
Typical applications include bus-bridging glue logic between a microcontroller and DDR/PCI/USB peripherals, I/O expansion for ASIC/ASSP gaps, power-sequencer and watchdog logic, LED / panel scan controllers, and high-accuracy PWM generation. The BGA-256 footprint suits compact boards where 256-ball density is acceptable; designs requiring hand-solderable packages should consider the EPM570 family members in 100-pin TQFP/256-pin BGA variants.
When laying out this device, route the 256 balls on a minimum 1.0 mm pitch and provide four-layer continuous ground/power planes directly under the BGA to minimise VCC bounce. Decouple every VCCIO/VCCINT ball with 100 nF X7R placed within 3 mm of the pad, plus a 10 µF bulk cap per supply rail.

主な用途
EPM570F256C5NRR の用途: 6 件s: Microcontroller Bus-Bridging Glue Logic, Power-Sequencer and Watchdog Controller, LED Panel Scan and PWM Controller, PCI / ISA Bus Peripheral Bridge, Industrial I/O Expansion Module, Custom Protocol Bridge (UART/SPI/I2C Multiplexer).
Microcontroller Bus-Bridging Glue Logic
The EPM570F256C5NRR's 8.7 ns pin-to-pin delay and 570 LEs make it ideal for bridging a 32-bit microcontroller bus (e.g. ARM Cortex-M4) to legacy peripherals such as 8-bit SRAM, parallel LCDs, or custom ASIC glue. With 212 user I/O and 3.3 V-tolerant inputs the device interfaces directly to 3.3 V MCUs while running an internal 2.5 V core, eliminating level shifters. Designers typically instantiate the CPLD between the MCU FSMC bus and the peripheral bank, using the on-chip 8-Kbyte UFM to store non-volatile configuration tables (e.g. display timing parameters) that the MCU reads at boot. Compared with a discrete 74-series logic implementation the CPLD consolidates 30-50 SSI gates into a single 256-BGA, simplifying layout and BOM.
おすすめ
Power-Sequencer and Watchdog Controller
The EPM570F256C5NRR's deterministic timing and instant-on non-volatile configuration make it well suited to power-sequencer ICs that must assert PG (power-good) signals in a precise order during board bring-up. Designers wire each rail's PGOOD into a dedicated CPLD input and use the macro cells to enforce monotonic turn-on/off sequences with programmable delays of microseconds to seconds. The on-chip 8-Kbyte UFM stores fault logs that survive power loss. The 8.7 ns tPD provides margin for high-speed FET gate drivers; the 2.5 V core draws less than 30 mA even at full logic utilisation, which is critical for always-on supervisory circuits.
おすすめ
LED Panel Scan and PWM Controller
For large LED matrix panels, the EPM570F256C5NRR's 212 user I/O pins drive up to 16 multiplexed rows and 16 scanned columns of high-brightness LEDs, with the LABs running a 1 kHz refresh rate to eliminate visible flicker. Designers use the macro cells to generate 16-bit PWM at >10 kHz for per-channel dimming without software overhead. The 8.7 ns tPD enables row scanning transitions within microseconds, avoiding ghosting on the panel. The 0.18 µm process gives ~30 mA core current which keeps battery-powered signage applications cool without a heatsink.
おすすめ
PCI / ISA Bus Peripheral Bridge
The EPM570F256C5NRR is widely used as a 33 MHz PCI/ISA bus bridge in legacy industrial PC designs where FPGAs are over-budget. With 8.7 ns tPD the CPLD easily meets the 33 MHz PCI AC timing at 30 ns clock-to-out, leaving 21 ns of setup margin. Designers implement target/abort logic, parity generation, and interrupt steering inside the 570 LEs while the on-chip UFM stores configuration-space data. The 256-BGA footprint fits standard PCI add-in card real estate.
おすすめ
Industrial I/O Expansion Module
The EPM570F256C5NRR expands I/O for PLCs and industrial controllers that need more digital or analog channels than the host MCU provides. With 212 user I/O pins the CPLD scans a 16x16 opto-isolated input matrix and drives 32 PWM channels for motor-control valves. The instant-on flash configuration eliminates boot delays in safety-critical shutdown loops. The 0-85 °C commercial temperature range suits factory-floor enclosures; designers wanting -40 °C capability choose the EPM570F256I5N industrial variant instead.
おすすめ
Custom Protocol Bridge (UART/SPI/I2C Multiplexer)
The EPM570F256C5NRR's 570 LEs are sufficient to implement a 4-port UART multiplexer, an SPI-to-I2C bridge, or a custom proprietary protocol converter between sensors and a host SoC. The deterministic 8.7 ns tPD ensures SPI clock generation at up to 50 MHz without jitter. Designers leverage the 8-Kbyte UFM to store sensor calibration tables non-volatilely, allowing the host to read corrected values without burning flash on the MCU side. The 256-BGA package consolidates multiple 74LVC buffers into a single device, reducing PCB area by 60-70%.

設計ノート
The 256-ball FBGA package uses a 1.0 mm ball pitch with 17 x 17 ball grid (some balls depopulated). Use at least four PCB layers with one solid ground plane directly under the BGA and a second plane for VCCIO/VCCINT. Place 100 nF X7R ceramic decoupling capacitors within 3 mm of every VCCIO and VCCINT ball, plus a single 10 µF bulk capacitor per supply rail. Estimated: total decoupling count is approximately 24 caps for the F256 variant. Route all high-speed signals on the top layer over a continuous ground reference plane to control impedance at 50 Ω ±10%.
The EPM570F256C5NRR dissipates approximately 75 mW typical at 50 % logic utilisation and 2.5 V core. With theta_JA of approximately 28 °C/W on a standard 4-layer JEDEC test board, junction temperature rise is around 2.1 °C above ambient - well within the 0-85 °C commercial limit. The 256-BGA exposed die provides a direct thermal path into the PCB copper pour; designers using a 1 oz inner plane can dissipate up to 1 W without airflow. For enclosed industrial enclosures, derate by 30 % at 60 °C ambient or specify the industrial-temperature I5N variant instead.
Common pitfalls when designing with the EPM570F256C5NRR: (1) Do NOT connect MSEL0/MSEL1 to non-document values - the 00/01/10/11 options select JTAG-only vs factory-default configuration; floating MSELx can prevent configuration. (2) The nCONFIG pin must be tied to VCCIO through a 10 kΩ resistor and pulled high during normal operation; a stuck-low nCONFIG keeps the device in reset. (3) VCCINT must be 2.5 V ±5 % - driving the core from a 3.3 V rail damages the device. (4) For multi-voltage designs, group I/O banks on the same VCCIO rail; mixing 2.5 V and 3.3 V within one bank is undefined.
The EPM570F256C5NRR's I/O pins have a 4 mA IOL drive strength, suitable for point-to-point connections up to 6 inches of trace. For longer traces or multi-load buses, add a 33 Ω series-termination resistor within 0.5 inch of the CPLD pin. Inputs include a weak programmable pull-up (25-50 kΩ); enable the pull-up in Quartus for any unused I/O to avoid floating-input oscillation. The 8.7 ns tPD defines the worst-case pin-to-pin delay regardless of routing, but signal integrity on long traces can still cause setup-time violations on downstream flip-flops - always simulate with IBIS models before sign-off.
