Typical Applications
EPM570F256C5 is suitable for 6 applications: FPGA / SoC Power-Up Sequencing, I/O Expansion and Bus Bridging, Protocol Translation (LVCMOS / LVTTL), JTAG Chain Control and TAP Multiplexing, Custom State Machines and Control Logic, Legacy 5 V Interface Adaptation.
FPGA / SoC Power-Up Sequencing
The EPM570F256C5 is widely used to sequence multiple power rails for downstream FPGAs, SoCs, and DSPs at board bring-up. With 160 user I/O, 570 Logic Elements, and a 5.4 ns pin-to-pin delay, the device can drive dozens of MOSFET enable gates, DC-DC PGOOD inputs, and RESET lines simultaneously while honoring inter-rail delay requirements in the millisecond range. The non-volatile flash boot ensures the CPLD is operational within microseconds of VCC applied, which is faster than any FPGA configuration cycle, so the CPLD can reliably hold downstream rails in reset until the FPGA is fully configured. According to the MAX II Device Handbook reference designs, JTAG-driven sequencing reduces BOM cost by replacing dedicated sequencer ICs.
Recommended
I/O Expansion and Bus Bridging
Designers use the EPM570F256C5 as a glue-logic bridge between processors that lack sufficient GPIO or whose I/O voltages differ. The MultiVolt I/O banks support 1.5 V, 1.8 V, 2.5 V, and 3.3 V signaling on a single die, allowing a 1.8 V application processor to drive 3.3 V peripheral logic without external level shifters. With 160 user I/O and 570 LE, the CPLD can implement parallel-to-parallel, parallel-to-serial, and serial-to-parallel bridges commonly needed in industrial controllers and POS terminals. According to Altera's reference designs, this eliminates 5-10 discrete buffer ICs from a typical bridge board, reducing cost and PCB area while preserving deterministic timing.
Recommended
Protocol Translation (LVCMOS / LVTTL)
The EPM570F256C5 implements bidirectional voltage-level translation between legacy 5 V-tolerant buses and modern low-voltage SoCs in mixed-signal systems. Its 160 I/O can be split across MultiVolt banks to translate 3.3 V to 1.8 V, 2.5 V to 1.5 V, or any other standard combination, with the 5.4 ns tPD supporting protocols such as SPI, I2C, UART, and slow parallel buses up to 50 MHz. According to the MAX II Device Handbook, the deterministic timing also makes the part well-suited for SD-card and SRAM interface bridging, where setup/hold windows are tight. Designers often replace 4-6 octal buffer/level-shifter ICs with one EPM570, simplifying layout.
Recommended
JTAG Chain Control and TAP Multiplexing
The EPM570F256C5 is used as a JTAG TAP multiplexer to share one boundary-scan controller among multiple downstream devices. With 160 I/O, the CPLD can drive TCK, TMS, TDI, and TDO lines for up to 8 cascaded TAPs while providing per-device TRST steering. According to the MAX II Device Handbook, the 5.4 ns tPD allows re-routing within a single TCK cycle, supporting high-speed boundary-scan at 50 MHz and beyond. Its in-system programmability means the JTAG topology itself can be reconfigured without board rework, which is valuable for in-field firmware updates and for boards shared between prototype SKUs.
Recommended
Custom State Machines and Control Logic
Engineers use the EPM570F256C5 to implement Moore/Mealy state machines that would otherwise consume valuable cycles on the host microcontroller. With 570 LE available, the part can host 20-30 independent state machines, each guaranteed to operate at up to 201 MHz toggle frequency with deterministic 5.4 ns pin-to-pin delay. According to the MAX II Device Handbook, this makes the part ideal for motor control PWM arbiters, multi-axis stepper sequencing, watchdog supervision, and HMI keyscan debouncers. The non-volatile flash boot means the controller is live within microseconds of VCC applied, eliminating the boot-latency risk that small FPGAs present.
Recommended
Legacy 5 V Interface Adaptation
Although the EPM570F256C5 core supply is 2.5 V / 3.3 V, its I/O pins are 5 V-tolerant through external series resistors and the MultiVolt I/O architecture. Industrial designs integrating legacy 5 V peripherals such as older PLCs, vacuum-fluorescent displays, or AT-cut industrial sensors use this part to bridge into modern 1.8 V SoCs without dedicated translator ICs. According to reference designs in the MAX II Device Handbook, the CPLD handles 5 V bus idle biasing via internal weak pull-ups while sustaining 3.3 V LVCMOS signaling on the SoC side. This shrinks the BOM and centralizes timing-critical translation in one deterministic logic block.

Key Differentiators
- Same die, Pb-free RoHS compliance (vs EPM570F256C5 (legacy SnPb))
- Faster timing closure (5.4 ns vs 7 ns) (vs EPM570F256C4N)
- Industrial temperature range (-40C to +100C) (vs EPM570F256C5 (commercial 0C to +85C))
Design Notes
Estimated: the FBGA-256 package has a ball pitch of 1.0 mm, which requires NSMD (non-solder-mask-defined) pads for reliable reflow. Place at least four via-in-pad arrays under the package center thermal balls for ground stitching. Use a 4-layer PCB with dedicated VCCINT and GND planes; do not route signals across the package shadow because the 256-ball grid has no center signal access. Maintain 0.2 mm trace/space rules for fan-out.
The MAX II device family does not support hot-socketing by default; VCCINT must rise monotonically and stabilize before any I/O pin is allowed to drive. Pull all JTAG signals (TCK, TMS, TDI, TRST) to defined states via 10 kohm resistors to prevent spurious boundary-scan activity during power-up. According to the MAX II Device Handbook, leaving CONF_DONE floating can cause configuration lockup; tie it to VCCIO via a 10 kohm pull-up.
For MultiVolt I/O banks, group pins by supply voltage; mixing 1.5 V and 3.3 V signals in the same bank causes the higher-voltage pins to back-power the lower-voltage rails through ESD diodes. According to the MAX II Device Handbook, each I/O bank has its own VCCIO pin; isolate banks with their own decoupling (0.1 uF X7R per bank plus a 10 uF bulk). Keep signal traces shorter than 50 mm to avoid ringing at 201 MHz toggle rates.
Estimated: at 201 MHz toggle frequency with 5.4 ns tPD, expect edge rates of 1-2 ns; use 50 ohm controlled-impedance traces on critical clocks. Place the JTAG header within 50 mm of the device to avoid stub reflections. Decouple each VCCIO pin with 0.1 uF X7R ceramic within 3 mm, and add one 10 uF bulk capacitor per supply rail within 25 mm of the package. Do not place inductors between VCCINT and the decoupling caps; ferrite beads on VCCINT are not recommended for MAX II devices.
Compliance Information
EPM570F256C5 is the legacy SnPb (non-Pb-free) variant. For RoHS-compliant equivalents, select the EPM570F256C5N. AEC-Q100 qualification is not provided for the MAX II family; use automotive-grade MAX V or Cyclone devices for AEC-Q100 requirements.
