EPM570GT100C4N - 570 LEs MAX II CPLD | Intel TQFP-100
MPN： EPM570GT100C4N ✓ 啟用中EPM570GT100C4N 概覽
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks with a programmable interconnect matrix, providing instant-on operation, deterministic timing, and in-system programmability (ISP). Within the programmable-logic taxonomy, CPLDs sit between small PALs/GALs and large FPGAs: more capable than discrete glue logic yet simpler, lower-cost, and lower-power than SRAM-based FPGAs. The MAX II family from Altera (now Intel FPGA) extends CPLDs into the logic-integration tier by adding an on-chip user flash memory block and supporting JTAG-based ISP for board-level configuration.
Key features of the EPM570GT100C4N include MultiVolt core and JTAG 1149.1 boundary-scan support, 8 Kbits of UFM usable for non-volatile parameter storage, fast propagation delays in the sub-nanosecond range (tPD approximately 4.5 ns for the C4 speed grade), and zero-power standby when the device is idle. It supports instant-on operation because configuration is stored in on-chip flash rather than external SRAM, so the device is functional within microseconds of VCC ramp.
Architecturally, the EPM570 uses the Logic Array Block (LAB) structure of the classic MAX family combined with the MultiTrack interconnect of the MAX 7000 series, exposed through the Quartus II / Quartus Prime design toolchain. The C4 speed grade is the second-fastest grade offered on the TQFP-100 footprint, balanced against the C5 (slower) and C3 (fastest) variants on the same package, enabling designers to trade timing margin for cost without re-laying out the PCB.
Typical applications include bus-interface bridging, I/O expansion, power-up sequencing, custom decode logic, glue logic replacement for ASICs, and configuration storage with on-chip UFM. Industrial control, consumer electronics, and portable/handheld designs benefit from the low quiescent current and instant-on behavior.
Design consideration: when migrating within the TQFP-100 footprint, the EPM570, EPM1270, and EPM2210 share vertical migration compatibility, allowing density upgrades without PCB redesign. The -4 speed grade targets cost-sensitive designs where the small extra timing margin versus -3 is acceptable.

典型應用
EPM570GT100C4N 適用於 6 應用s: Bus Interface Bridging and Glue Logic, Power-Up Sequencing and Reset Control, LED Display Driving and Multiplexing, Industrial Control and Factory Automation, I/O Expansion and Custom Peripheral Emulation, Portable and Handheld Consumer Devices.
Bus Interface Bridging and Glue Logic
The EPM570GT100C4N's 570 LEs, 76 I/Os, and MultiVolt I/O bank (1.5/1.8/2.5/3.3 V) make it a natural fit for bridging between microprocessors, memories, and peripherals operating at mismatched logic levels. In a typical design the CPLD sits between a 1.8 V application processor and 3.3 V peripherals, performing address/data latch, chip-select decode, and voltage-level translation in a single chip. The MAX II instant-on behavior ensures bus control is available before the main SoC finishes its boot ROM, eliminating the need for separate discrete glue logic. The 8 Kbit UFM can store board ID and revision strings readable over I2C for inventory traceability.
推薦
Power-Up Sequencing and Reset Control
The EPM570GT100C4N's instant-on flash-based configuration (no boot PROM) and deterministic timing make it ideal for power-rail sequencing in multi-voltage systems. The device can assert up to 76 enables within nanoseconds of VCC ramp, sequencing DC-DC converters, LDOs, and ASIC core rails in the correct order to prevent latch-up. The on-chip UFM stores trim values and fault thresholds. Compared with discrete supervisor timers, a single EPM570 replaces multiple reset ICs and gives the designer full control over sequencing delays through Quartus Prime logic; the 1.8 V VCCINT allows direct interface to low-voltage ASICs.
推薦
LED Display Driving and Multiplexing
In industrial and consumer LED panels the EPM570GT100C4N provides row/column multiplexing, PWM dimming, and brightness correction in a single device. The 76 I/Os are sufficient to drive up to a 32x16 mono LED matrix with row-scanning at refresh rates above 1 kHz, eliminating flicker. Its 8 Kbit UFM can store per-panel gamma curves. Compared with microcontroller-based solutions, the CPLD's deterministic sub-5 ns propagation eliminates timing jitter that causes visible scan-line artifacts in video walls. The MAX II instant-on ensures display content appears immediately at power-on without bootloader delay.
推薦
Industrial Control and Factory Automation
Factory-automation systems require deterministic logic for sensor interfacing, motor-step generation, and protocol conversion. The EPM570GT100C4N provides 570 LEs of deterministic logic for encoder quadrature decoding, PWM generation for step/servo drives, and protocol bridging (RS-232 to RS-485, SPI to UART) without RTOS overhead. The MultiVolt I/O supports 24 V-tolerant interfaces through external resistor dividers, and the C4 speed grade provides the timing margin needed for sub-microsecond control loops. For industrial temperature range, the EPM570GT100I4N is the drop-in alternative rated -40C to +85C.

I/O Expansion and Custom Peripheral Emulation
When a microcontroller runs out of GPIO or UART/SPI channels, the EPM570GT100C4N provides 76 additional I/Os that can be configured as shift-register expanders, PWM generators, or custom serial-protocol engines. The CPLD runs from the MCU's SPI or I2C control port, presenting register-mapped GPIO to the application code. The 8 Kbit UFM stores configuration words that re-program the CPLD's function on the fly. Compared with discrete I/O expanders like the PCA9555, the EPM570 offers unlimited protocol customization at lower per-I/O cost, while keeping deterministic sub-5 ns response for real-time control.
推薦
Portable and Handheld Consumer Devices
Battery-powered consumer devices benefit from the EPM570GT100C4N's low quiescent current and instant-on flash configuration. The CPLD can wake a smartphone accessory, USB device, or handheld instrument within microseconds of button press, routing power and asserting control signals before the main SoC boots. The 1.8 V VCCINT operates directly from a single Li-ion cell through a small LDO; the MultiVolt I/O connects directly to 1.8 V SoCs and 3.3 V displays. Compared with discrete logic gates, the CPLD reduces BOM count and PCB area by 60-80%, critical for sub-50 cm² handheld designs.

設計說明
The EPM570GT100C4N requires a clean 1.8 V core supply (VCCINT) with up to 100 mA peak current during flash programming; decoupling capacitors of 0.1 µF and 10 µF must be placed within 5 mm of each VCCINT pin. VCCIO bank supplies can be set to 1.5 V, 1.8 V, 2.5 V, or 3.3 V independently; each VCCIO pin also needs 0.1 µF + 10 µF decoupling. Power-on ramp time should be slower than 100 µs to ensure proper flash configuration; faster ramps require an external supervisor IC.
TQFP-100 with 0.5 mm pitch demands 4-layer PCB with 0.2 mm drill/0.4 mm pad for the gull-wing leads; use an 8 mil trace/space rule and microvia-in-pad for the inner fan-out. Place the JTAG header (TDI/TMS/TCK/TDO + GND) within 50 mm of the device to avoid signal-integrity issues; add 10 kΩ pull-ups on TDI/TMS/TCK to prevent floating JTAG. Decoupling capacitor loop area must be kept below 1 cm² to minimize parasitic inductance.
Do not confuse G-suffix TQFP-100 with F-suffix FBGA or Q-suffix Quad Flat Pack; pinouts are NOT compatible across package families even at the same LE count. When migrating between speed grades (-3/-4/-5), confirm your design's worst-case fMAX falls within the new grade's tPD specification. The -4 grade is mid-range; if your timing margin is below 10%, step up to -3; if you have >25% margin, drop to -5 for cost savings. Verify JTAG chain order in the Quartus Prime programmer before in-system programming to avoid accidentally configuring a downstream device.
