MPN： EPM240GT100C5 ✓ 啟用中EPM240GT100C5 概覽
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the instant-on behavior of flash memory with the deterministic timing of a classic PAL/GAL architecture. It belongs to the broader hierarchy of programmable logic, sitting below FPGAs in density but above simple PLDs in capability, and is widely used for bus decoding, I/O expansion, power-up sequencing, and address decoding in microcontrollers, ASICs, and ASSPs. The MAX II family is the industry reference for low-cost, low-power, non-volatile logic integration.
Key features of the EPM240GT100C5 include 4.7 ns tPD (fastest speed grade, C5), 80 user I/O, MultiVolt core supporting 1.8V/2.5V/3.3V LVCMOS/LVTTL interfaces, an 8-Kbit UFM block, in-system programmability via JTAG, and a commercial 0C to 85C operating temperature range. The G-suffix variant targets the TQFP-100 footprint and is part of Intel's mature, broadly stocked MAX II portfolio.
The architecture uses a global interconnect fabric routing all 240 logic elements through a uniform switch matrix, giving consistent, deterministic timing regardless of placement. Internal pull-up resistors on every I/O simplify single-supply designs by eliminating external resistors on unused or idle pins.
Typical applications include I/O expansion and bus bridging on 8051, ARM Cortex-M, and PIC platforms; address decoding for DSPs and microprocessors; power-up and reset sequencing for multi-rail systems; and replacement of discrete 74-series glue logic to consolidate 4-6 packages into a single device. Designers also use the 8-Kbit UFM for storing board parameters such as serial numbers, MAC addresses, or calibration data.
When designing with this part, observe the 1.71V to 1.89V VCCINT core supply requirement and the separate VCCIO bank supply that can be tied to 1.5V, 1.8V, 2.5V, or 3.3V depending on the interfacing logic. Quartus II Web Edition (or newer Quartus Prime Lite) is required for design entry, synthesis, fitting, and JTAG programming.

典型應用
EPM240GT100C5 適用於 6 應用s: Microcontroller I/O Expansion and Bus Bridging, Address Decoding for DSP and Microprocessor Systems, Power-up and Reset Sequencing for Multi-Rail Systems, 74-Series Glue Logic Consolidation, Industrial Control and Factory Automation I/O, Communications and Networking Equipment Glue Logic.
Microcontroller I/O Expansion and Bus Bridging
The EPM240GT100C5 fits 8051, ARM Cortex-M, PIC, and AVR microcontroller I/O expansion because its 80 user I/O and 240 logic elements can decode multiplexed address/data buses or generate chip-select signals with a deterministic 4.7 ns tPD. In a typical 16-bit external memory interface, the device replaces 4-6 packages of 74HC logic with a single instant-on device, while its 1.5V-3.3V MultiVolt I/O accepts 1.8V Cortex-M signals directly. The 8-Kbit UFM stores non-volatile board parameters (MAC address, calibration constants) eliminating a separate EEPROM.
推薦
Address Decoding for DSP and Microprocessor Systems
The EPM240GT100C5 is a strong fit for address decoding in DSP and microprocessor subsystems because its 4.7 ns pin-to-pin delay and 240 logic elements support multiple overlapping address windows in a single device. In a typical TI C6000 or NXP i.MX8 memory map, the CPLD generates the chip-select logic for SDRAM, Flash, and peripherals while its non-volatile flash fabric eliminates boot-time configuration. The MultiVolt I/O ring natively bridges 3.3V microprocessor buses with 1.8V peripherals, removing discrete level shifters.
推薦
Power-up and Reset Sequencing for Multi-Rail Systems
The EPM240GT100C5 suits multi-rail power sequencing because it operates from a stable 1.8V core supply and 80 I/O can monitor or drive PG/EN signals to multiple DC-DC converters and LDOs. Compared to discrete supervisor ICs, the CPLD allows fully programmable rail ordering, monotonic timing offsets, and fault handling without a firmware dependency. Its instant-on behavior (non-volatile fabric) ensures the sequencing logic is active before any host processor has begun executing code.
推薦
74-Series Glue Logic Consolidation
The EPM240GT100C5 replaces 4-6 packages of 74HC, 74AHC, or 74LVC glue logic (gates, muxes, flip-flops, decoders) with a single TQFP-100 device, reducing BOM cost and PCB area. Its 240 logic elements and 80 I/O can map an entire board's discrete logic while reducing the part count and assembly errors. Compared to discrete logic, the CPLD also allows late-stage design changes via JTAG reprogramming rather than board respins.
推薦
Industrial Control and Factory Automation I/O
The EPM240GT100C5 is suitable for industrial PLC and factory-automation I/O conditioning because its 80 user I/O and 4.7 ns tPD support high-speed digital signal routing for encoder counters, optocoupler interfaces, and fieldbus glue logic. The commercial 0C to 85C temperature range covers most cabinet environments; designs requiring industrial -40C to 100C should choose an I-suffix variant such as EPM240GT100I5N. The non-volatile instant-on fabric is critical for machinery that must boot deterministically without waiting for a configuration download.
推薦
Communications and Networking Equipment Glue Logic
The EPM240GT100C5 is commonly used in router, switch, and small-cell designs for board-level glue logic between Ethernet PHYs, SERDES devices, microprocessors, and FPGAs, where its 4.7 ns tPD and 80 I/O enable deterministic chip-select generation and protocol bridging. Its MultiVolt I/O natively interfaces 3.3V Ethernet PHYs and 1.8V processor buses without level shifters. The 8-Kbit UFM can store MAC addresses and board revision data, reducing external EEPROM cost.

- Broader stock and channel availability in commercial temperature range (對比EPM240GM100I5N)
設計說明
Estimated: at typical 50 MHz toggle activity across 30 of 80 I/O driving 5 pF loads, the EPM240GT100C5 draws approximately 20-30 mA from the 1.8 V VCCINT supply. Provide a 1.0 uF X7R ceramic decoupling capacitor as close as possible to each VCCINT pin and a 0.1 uF bypass for every VCCIO pin. Tie any unused VCCINT/VCCIO pins to their respective supply rails; do not leave them floating.
Estimated: the TQFP-100 (14x14 mm) package has a 0.5 mm lead pitch. Use a 4-layer PCB with continuous power and ground planes to minimize the ground bounce that arises from the simultaneous switching of 80 I/O. Place JTAG TCK, TMS, TDI, TDO, and nCONFIG/nSTATUS traces away from high-speed signal edges to avoid ISP programming failures during in-field updates.
Do not apply power to VCCIO before VCCINT, as reverse power sequencing can cause latch-up. Always hold nCONFIG low during power-up until both VCCINT and VCCIO are stable. The UFM block requires the user logic to sequence its read/write commands correctly - do not access the UFM during JTAG boundary-scan operations, as this can corrupt the flash state.
Estimated: pin-to-pin timing on the EPM240GT100C5 is deterministic at 4.7 ns tPD regardless of placement, but propagation delay through the interconnect fabric can vary with fan-out. Use the Quartus Prime Classic Timing Analyzer to verify tPD, tCO, and tSU for your specific pin assignments before committing to layout; avoid driving more than 8-10 mA per I/O to stay within the 5 mA DC sink/source spec.
