Typical Applications
EPM570T100C3 is suitable for 6 applications: I/O Expansion & Voltage Level Translation, Power-On Sequencing & Reset Controller, Bus Decoding & Memory Address Mapping, Industrial Glue Logic & ASIC Replacement, LED Display Multiplexing & Sign Control, Communication Protocol Bridging.
I/O Expansion & Voltage Level Translation
The EPM570T100C3 provides 76 user I/Os in a 100-pin TQFP and supports MultiVolt I/O at 1.5 V, 1.8 V, 2.5 V, and 3.3 V, making it ideal for bridging mixed-voltage buses. Its 304 MHz toggle rate comfortably exceeds the bandwidth required for SPI, I2C, UART, and parallel MCU expansion. In a 3.3 V MCU to 1.8 V ASIC bridge, the part eliminates discrete level translators and shrinks BOM cost; the on-chip 8 Kbit UFM can store board-identity or calibration data without an external EEPROM.
Recommended
Power-On Sequencing & Reset Controller
With instant-on flash-based configuration and deterministic macrocell timing, the EPM570T100C3 reliably orchestrates power-up sequences in multi-rail systems. Its 76 I/Os allow parallel control of 10+ supply enables with per-rail delay programming; the 304 MHz frequency lets it monitor a PG (power-good) feedback loop at sub-microsecond resolution. The non-volatile flash eliminates the boot ROM typically required by an MCU, reducing solution cost and improving reliability in industrial and telecom designs.
Recommended
Bus Decoding & Memory Address Mapping
The EPM570T100C3 implements address decoders, chip-select generators, and wait-state controllers for SRAM, NOR flash, and SDRAM interfaces. The MAX II macrocell architecture provides combinatorial paths with predictable propagation delay, which is essential for synchronous memory interfaces where setup/hold margins are tight. With 440 macrocells and 76 I/Os, designers can map a full 24-bit address bus and several control signals without external logic, simplifying the host CPU's role to data movement only.
Recommended
Industrial Glue Logic & ASIC Replacement
In industrial PLC and motor-control boards, the EPM570T100C3 replaces discrete 74-series glue logic with a single programmable device. Its 0.18 µm flash process and industrial-grade silicon deliver high ESD robustness and predictable behavior across the commercial temperature range. Engineers use it to consolidate encoder counters, PWM gating, watchdog logic, and isolated SPI bridges into one BGA-replacement IC, cutting board area by 30–50% versus discrete TTL.
Recommended
LED Display Multiplexing & Sign Control
The EPM570T100C3 drives large multiplexed 7-segment or dot-matrix LED displays by scanning rows and refreshing columns at hundreds of Hz without CPU intervention. Its 76 I/Os comfortably handle 8 digits with row/column split, and the 304 MHz internal frequency supports >1000 Hz refresh to eliminate flicker. The 8 Kbit UFM stores lookup tables, fonts, and animation frames, removing the need for external ROM and enabling battery-backed or battery-less signage.
Recommended
Communication Protocol Bridging
The EPM570T100C3 acts as a programmable bridge between SPI, I2C, UART, and parallel interfaces in embedded designs. Its deterministic macrocell timing and 304 MHz performance allow translation at speeds up to 50 MHz without protocol corruption. Designers also leverage the on-chip UFM to store protocol configuration tables and bit-banged timings, enabling firmware-free bridging for legacy peripherals that lack native MCU support in modern SoCs.

Key Differentiators
- Fastest commercial speed grade for EPM570 in T100 package (vs EPM570T100C5N)
- Pb-free / RoHS-compatible finish in same die/package (vs EPM570T100C3N)
- Wider operating temperature range with same T100 footprint (vs EPM570T100I5N)
Design Notes
The EPM570T100C3 requires two separate supply rails: VCCINT (2.5 V or 3.3 V core) and one or more VCCIOx bank supplies for I/O. Per the Intel MAX II handbook, place a 0.1 µF decoupling capacitor within 5 mm of every VCCINT and VCCIOx pin, and add a 10 µF bulk capacitor on each supply rail. Inadequate decoupling causes transient VCC sag that manifests as logic errors at high toggle rates, particularly above 100 MHz.
Route JTAG signals (TDI, TMS, TCK, TDO) as a daisy-chain with no stubs and keep traces shorter than 150 mm to maintain signal integrity for ISP programming. Place a 4.7 kΩ pull-up on nCONFIG and a 4.7 kΩ pull-up on nCE (or tie nCE low) per datasheet recommendation; floating nCE prevents configuration. Reserve a JTAG header footprint (standard 10-pin Altera layout) for production programming access.
The 100-pin TQFP package has 76 user I/Os split across four I/O banks (banks 1–4). Each bank supports MultiVolt at 1.5 V, 1.8 V, 2.5 V, or 3.3 V independently, but every pin in a bank shares the same VCCIOx. For mixed-voltage designs, group same-voltage pins into the same bank to avoid contention. Series termination resistors (22–33 Ω) are recommended on outputs driving traces longer than 50 mm at frequencies above 50 MHz.
Do not confuse the C3 speed grade with the C3 commercial-temperature suffix: speed grade and temperature grade are independent. The EPM570T100C3 means commercial-temperature + C3-speed; EPM570T100I5N means industrial-temperature + I5-speed. Mixing these when ordering can result in parts that operate outside the required temperature window or fail timing closure. Also note that the UFM block has a finite endurance (typ. 1000 erase/program cycles) — avoid using it for high-frequency data logging.
Use a 4-layer PCB stack-up with continuous ground plane beneath the TQFP to provide low-impedance return paths for high-frequency switching. The exposed die-attach paddle on TQFP packages must be soldered to the ground plane for thermal relief — at full 76-I/O toggle rate the device can dissipate up to ~200 mW. Maintain at least 0.2 mm clearance between TQFP pin pads and adjacent vias to prevent solder bridging during reflow.
Compliance Information
The EPM570T100C3 is the legacy (non-N) variant with SnPb terminal finish and is NOT RoHS-compliant; choose EPM570T100C3N for RoHS-compliant designs. AEC-Q100 is not applicable to commercial-grade CPLDs; select MAX II automotive variants for AEC-Q100 needs.
