EPM240GT100C4N - MAX II CPLD, 192 Macro Cells, TQFP-100 | Intel
MPN： EPM240GT100C4N ✓ 啟用中EPM240GT100C4N 概覽
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the instant-on behavior of classic PAL/GAL architecture with modern look-up-table-based logic blocks. Within the broader taxonomy, the EPM240GT100C4N belongs to the MAX II family of low-power, instant-on CPLDs, which sits beneath the FPGA category in the programmable logic hierarchy and above discrete 74-series glue logic in terms of integration density.
Key features include MultiVolt core and I/O support, in-system programmability through IEEE 1149.1 JTAG, an on-chip voltage regulator allowing single 3.3 V supply operation, and a typical quiescent current in the low milliamp range. The 100-pin TQFP package uses a 0.5 mm pitch and a 16 × 16 mm body, providing a generous number of user I/O pins for bus-bridging, interface aggregation, and control-logic replacement tasks.
The MAX II architecture is built around Logic Array Blocks (LABs) connected via a MultiTrack interconnect, with each LAB containing 10 Logic Elements (LEs). On-chip flash configuration memory enables instant-on functionality within microseconds, eliminating the configuration delay associated with SRAM-based FPGAs and making this device attractive for power-sequenced designs and boot-loader replacement.
Typical applications include I/O expansion and bus bridging in industrial controllers, address decoding and glue-logic replacement in networking line cards, motor-control peripheral aggregation in factory automation, and board-level control logic in test-and-measurement equipment. The wide multi-voltage I/O support simplifies mixed-rail designs where the CPLD must interface with both legacy 5 V-tolerant busses and modern 1.8 V processors.
When designing with this device, ensure that the JTAG chain is properly terminated to avoid programming failures, and pay attention to the I/O bank supply grouping defined in the datasheet to prevent contention when mixing 3.3 V and 1.8 V signals. Quartus II or the latest Quartus Prime toolchain is required for synthesis, fitting, and programming.

典型應用
EPM240GT100C4N 適用於 6 應用s: Bus Bridging and Protocol Conversion, Industrial Control and Glue Logic Replacement, I/O Expansion for Microcontrollers, Address Decoding and Chip Select Generation, LED Display and Signage Control, Test and Measurement Front-End Logic.
Bus Bridging and Protocol Conversion
The EPM240GT100C4N excels at bus-bridging between mismatched voltage domains and protocols in industrial and embedded systems. Its MultiVolt I/O support (1.5/1.8/2.5/3.3 V) allows direct interfacing between legacy 5 V-tolerant busses via external resistors and modern 1.8 V processors without external level shifters. With 80 user I/Os in the TQFP-100 package and a 6.1 ns tPD, the device can implement address-latch, chip-select decode, and width-conversion logic between 8/16/32-bit busses running at 50-80 MHz. The instant-on flash-based architecture means bus bridges come up active in microseconds, which is critical when a host CPU needs immediate access to peripheral memory at reset.

Industrial Control and Glue Logic Replacement
In factory-automation and motor-control boards, the EPM240GT100C4N replaces dozens of discrete 74-series glue-logic ICs with a single programmable device, reducing board area and BOM cost. With 192 macro cells and 240 logic elements, it can implement complete state machines, PWM interfaces, and encoder-decoders for servo drives. The 100-pin TQFP package's 80 user I/Os comfortably handle 4-6 incremental encoder channels plus parallel I/O expansion. The non-volatile flash configuration eliminates external boot PROMs and provides field-upgradeability via JTAG without removing the device from the board.
推薦
I/O Expansion for Microcontrollers
When a microcontroller's GPIO count is insufficient, the EPM240GT100C4N serves as a programmable I/O expander connected via SPI or parallel bus. Each of the 80 user I/Os can be configured as input, output, or bidirectional with custom interrupt-on-change logic. The 247.5 MHz maximum internal frequency allows the CPLD to handle high-speed pulse trains and quadrature decoding that would otherwise burden the MCU's CPU. With a 6.1 ns propagation delay, interrupt-to-output response stays below 20 ns total including bus access, making it suitable for real-time industrial protocols.
推薦
Address Decoding and Chip Select Generation
The EPM240GT100C4N is widely deployed for address decoding and chip-select generation in 16/32-bit embedded systems, where it replaces discrete PAL/GAL devices and 74HC138/139 decoders. With 192 macro cells and a 6.1 ns tPD, the device can decode up to 8-12 chip-select outputs from a 24-bit address bus with less than 15 ns of added access time. The flash-based configuration allows late-stage board redefinition - designers can change memory maps on the production line via JTAG without respinning the PCB, a major advantage over hard-wired decoders.
推薦
LED Display and Signage Control
Lighting and signage controllers use the EPM240GT100C4N to multiplex rows and columns of LED matrices, generate PWM dimming waveforms, and scan push-button/keypad inputs simultaneously. With 80 user I/Os, a single device can drive a 16-row by 16-column LED matrix with 256 pixels while still leaving pins for status LEDs and serial interfaces. The instant-on capability ensures that LED patterns appear within milliseconds of power-up, eliminating the visible flicker that SRAM-based FPGAs exhibit during their configuration phase.
推薦
Test and Measurement Front-End Logic
Test-and-measurement instruments deploy the EPM240GT100C4N as a flexible front-end for signal routing, range switching, and trigger conditioning. Its 6.1 ns tPD allows the device to participate in sub-100 MHz trigger logic without degrading measurement bandwidth, while 80 user I/Os accommodate multi-channel multiplexer control. The JTAG ISP capability lets manufacturers reuse the same hardware across multiple product variants by simply reprogramming the CPLD, compressing inventory SKUs and shortening time-to-market.

主要差異化特點
- Instant-on non-volatile flash configuration (對比Small SRAM-based FPGAs (e.g., Cyclone series))
- Multi-voltage I/O without external level shifters (對比Discrete 74-series glue logic)
- Higher user I/O count at same density (對比EPM1270T144C5N (144-pin TQFP, 980 LEs))
設計說明
The TQFP-100 package uses 0.5 mm pitch leads, which requires careful PCB design: use 0.2-0.25 mm trace-and-space with solder mask defined (SMD) pads for reliable assembly. Place all four board layers with a continuous ground plane directly under the device to provide thermal dissipation and controlled impedance for high-speed I/O. Keep JTAG traces (TCK, TMS, TDI, TDO) short and isolated from switching signals to avoid programming failures.
Do not exceed the 4.6 V absolute maximum I/O voltage, even on unused pins - configure unused I/Os as inputs with internal weak pull-ups in the Quartus pin-assignment file to prevent floating-pin oscillation that can raise ICC. When mixing 3.3 V and 1.8 V I/O banks, ensure each VCCIO bank has its own decoupling capacitor pair (0.1 µF plus 10 µF) placed within 5 mm of the corresponding supply pin.
The 247.5 MHz internal frequency can drive I/O transitions in the 80-150 MHz range, so treat all output signals as transmission lines for traces longer than 25 mm. Use 33 Ω series-termination resistors at the CPLD output for traces exceeding one-quarter of the signal rise time in electrical length. For clock outputs, route on an inner layer stripline with reference ground plane on both sides to minimize radiated EMI.
