Safe Operating Area (SOA) & Thermal Characteristics
No official SOA curve available for this digital IC. Always operate within absolute maximum ratings specified in the datasheet. Ensure adequate cooling and derate as needed.
Typical Applications
EPM570T100C3N is suitable for 6 applications: Bus Interface Bridging and Protocol Glue Logic, Power Sequencing and Reset Controller Logic, LED Display Driver and Scanning Logic, Industrial Control Board Glue Logic Replacement, I/O Expansion for Microcontrollers and SoCs, Legacy Bus Interfacing for Networking Equipment.
Bus Interface Bridging and Protocol Glue Logic
The EPM570T100C3N's 440 macrocells and 5.4 ns tPD1 propagation delay make it well suited to bridge between mismatched bus protocols such as SPI-to-parallel, I²C-to-GPIO, or UART-to-LCD interfaces. Its MultiVolt I/O banks can be configured at 1.8 V on one bank and 3.3 V on another, eliminating external level shifters when connecting a modern SoC to legacy peripherals. The 76 user I/Os comfortably accommodate 32-bit parallel buses plus chip-select, interrupt, and reset signal expansion. Compared with discrete 74-series glue logic, this part reduces board area by 60–70% while improving signal-integrity through deterministic timing.
Recommended
Power Sequencing and Reset Controller Logic
The EPM570T100C3N's deterministic 5.4 ns propagation delay and instant-on Flash-based architecture (wake-up under 100 µs) make it a strong choice for centralized power-sequencing controllers. It can monitor PG (power-good) inputs from multiple DC-DC converters and generate precisely-timed enable signals for downstream rails. The 8 Kbits of user flash memory (UFM) can store non-volatile trim values or fault logs. Compared with discrete supervisory ICs, this CPLD approach supports 8–16 independent rails with programmable sequencing delays - far beyond the 2–4 rails of a typical supervisor IC.
Recommended
LED Display Driver and Scanning Logic
The 304 MHz maximum internal frequency and 76 user I/Os of the EPM570T100C3N support multiplexed LED matrix scanning for panels up to 64×64 pixels at video refresh rates. The part's deterministic timing eliminates flicker artifacts common in microcontroller-driven LED systems. Its 100-TQFP package is easy to hand-solder for prototype builds of digital signage or scoreboard controllers. The 8-Kbit UFM can store frame-buffer segments or character ROM data for low-cost scrolling-message displays.
Recommended
Industrial Control Board Glue Logic Replacement
The EPM570T100C3N is frequently used as a replacement for obsolete 5 V 22V10/32V10 PAL/GAL devices on legacy industrial control boards. Its 3.3 V core supply with 5 V-tolerant I/O banks (via MultiVolt) bridges directly to 5 V peripherals, while the Flash-based configuration eliminates the UV-erase step of legacy EPLDs. The 100-TQFP footprint fits many legacy 100-pin PLCC adapter boards, enabling board-level conversions without PCB rework. Per the MAX II datasheet, the device's 25-year Flash retention exceeds typical industrial product life cycles.
Recommended
I/O Expansion for Microcontrollers and SoCs
When a microcontroller or SoC runs out of GPIO pins, the EPM570T100C3N can add 76 additional I/Os via simple SPI or I²C control from the host. Its 5.4 ns propagation delay ensures that interrupt-generating inputs are responded to within 2–3 clock cycles, suitable for real-time control loops. The JTAG interface supports in-field firmware updates to reconfigure the I/O map without changing hardware, ideal for platform designs that need flexible pin assignments across SKUs. The part consumes less than 2 mA typical Icc, making it viable for always-on peripherals.
Recommended
Legacy Bus Interfacing for Networking Equipment
The EPM570T100C3N is commonly deployed in router, switch, and base-station boards to interface legacy 8-bit/16-bit microprocessor buses to modern high-speed SERDES links. Its 5.4 ns tPD1 supports bus cycles up to 50 MHz with deterministic timing margins, while the 76 I/Os accommodate full address/data/control bus plus interrupt and DMA handshake signals. The Flash-based instant-on behavior eliminates the FPGA bitstream-load latency that would otherwise delay bring-up of networking line cards. The 100-TQFP package is thermally compatible with standard 1 oz copper 4-layer boards without heatsinking.

Key Differentiators
- Non-volatile Flash-based instant-on architecture (vs SRAM-based FPGAs (e.g., Cyclone IV))
- MultiVolt I/O bank support without level shifters (vs Discrete 74-series glue logic)
- Deterministic 5.4 ns pin-to-pin propagation delay (vs Microcontroller-driven logic (e.g., GPIO toggling))
Design Notes
The EPM570T100C3N requires separate VCCINT (2.5 V or 3.3 V core) and per-bank VCCIO supplies (1.5/1.8/2.5/3.3 V). Decouple each VCCINT pin with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, and add a 10 µF bulk capacitor near the IC. Each VCCIO bank pin should have its own 0.1 µF + 10 µF pair. Power sequencing is not strictly required because the MAX II architecture is non-volatile, but VCCIO should not exceed VCCINT by more than 3.6 V during power-up to avoid latch-up.
Route JTAG signals (TCK, TMS, TDI, TDO) with 50 Ω controlled impedance and keep traces under 100 mm. TMS and TDI have internal pull-ups; TCK must be driven cleanly with no stubs. Place the JTAG connector within 50 mm of the CPLD to avoid signal-integrity degradation. For multi-device JTAG chains, include a 4.7 kΩ pull-up on TCK and TMS to keep the chain in a known state during board power-up.
Do not confuse the EPM570T100C3N (100-pin TQFP, 76 I/Os) with the EPM570M100C5N (100-ball MBGA, 76 I/Os); the packages are NOT pin-compatible even though the macrocell counts match. Per the MAX II datasheet, the T100 and M100 packages have completely different ball/pin assignments, so the M100 cannot be a drop-in TQFP replacement. Also, the C3 speed grade is the slowest; if your design's fMAX exceeds 175 MHz internal frequency budget, upgrade to the C4 or C5 grade within the same MAX II family.
Compliance Information
RoHS and REACH compliant per Intel product page; commercial-grade (0–85 °C) only - not AEC-Q100 qualified. Choose EPM570T100I3N for industrial temperature grade.
