Typical Applications
EPM240T100I5 is suitable for 6 applications: Industrial I/O Expansion and Bus Bridging, Power Sequencing and Supervisor Logic, Address Decoding for Memory and Peripheral Subsystems, LED Display Driving and Multiplexing, Consumer Electronics Glue Logic, Communications Infrastructure Glue Logic.
Industrial I/O Expansion and Bus Bridging
The EPM240T100I5 is widely used as a glue-logic device between microcontrollers and peripheral buses in industrial controllers. Its 240 logic elements and 80 user I/O pins comfortably handle 8- or 16-bit bus address decoding, level shifting between 3.3V and 1.8V rails via MultiVolt I/O, and protocol conversion (for example, SPI-to-parallel LCD bridging). The instant-on flash configuration ensures bus arbitration logic is live before any host MCU boots - critical for fail-safe I/O. Industrial temperature grade (-40C to +100C) lets it operate in factory-floor enclosures without derating. Typical companion devices: STM32F4 host MCU, 74LVC245 transceivers, and external SRAM.
Recommended
Power Sequencing and Supervisor Logic
The EPM240T100I5's deterministic startup from non-volatile flash makes it ideal for power-rail sequencing in multi-rail systems (FPGA + DDR + analog). The 192 macrocells can implement 8-12 independent sequencer channels with programmable delay lines, while the integrated 8-Kbit User Flash Memory stores rail configuration and trim values. Compared to a discrete supervisor IC chain, a single CPLD reduces PCB area and allows firmware updates via JTAG without changing the supervisor chip. Place the CPLD close to the regulator enable pins and use 3.3V core tied to the first rail in the sequence. Power dissipation is typically under 200 mW across the full industrial temperature range.
Recommended
Address Decoding for Memory and Peripheral Subsystems
Address decoding is the canonical MAX II CPLD application, and the EPM240T100I5 with 240 LEs can handle 16-bit address decoding with chip-select generation for 8-16 memory or peripheral devices. Typical use: decoding the upper address lines of an external bus into individual CS# signals for SRAM, Flash, and registers. The 4-7 ns typical propagation delay adds only a single-cycle penalty in most 50-100 MHz bus designs. Industrial temperature grade suits embedded PC/104 and CompactPCI boards. JTAG-based ISP lets you update the decode map in the field without removing the board.
Recommended
LED Display Driving and Multiplexing
The EPM240T100I5 can drive multiplexed 7-segment LED displays, dot-matrix panels, or LED indicator arrays in consumer and appliance products. Up to 80 user I/O pins support row/column multiplexing of 8-digit 7-segment displays with BCD-to-7-segment decoding implemented inside the CPLD - replacing 4-6 discrete decoder/driver ICs. The non-volatile configuration means display patterns are restored instantly on power-up, and the 8-Kbit UFM can store up to 256 custom characters or icon bitmaps. Industrial temperature grade suits appliance front panels and outdoor signage controllers.
Recommended
Consumer Electronics Glue Logic
The EPM240T100I5 is often used as the glue-logic hub in set-top boxes, networking appliances, and printer controllers, where it handles I2C/SPI muxing, GPIO expansion, button matrix scanning, and watchdog logic. Its 3.3V core with 1.5V-3.3V MultiVolt I/O bridges directly between an application processor's 1.8V GPIO and 3.3V peripherals without external level shifters. The small TQFP-100 footprint (16x16 mm) keeps board area low, and JTAG programming lets production lines configure the device late in the build cycle. Typical power consumption is around 30-50 mA in typical operating conditions.
Recommended
Communications Infrastructure Glue Logic
In networking line cards and base-station equipment, the EPM240T100I5 is used for low-speed control-plane glue logic such as PHY reset sequencing, MDIO bus muxing, and front-panel LED driving. Its deterministic timing from non-volatile flash storage is preferred over SRAM-based FPGAs for control-plane functions that must be live at power-on, before the management CPU boots. The industrial temperature rating fits outdoor or uncontrolled-temperature deployments, and the JTAG ISP chain can be paralleled across multiple line cards for fleet updates. MultiVolt I/O interfaces directly to 1.8V and 2.5V PHYs without external translators.

Key Differentiators
- Industrial temperature rating in TQFP-100 (vs EPM240T100C5N)
- Same TQFP-100 footprint as higher-density siblings (vs EPM240T100A5N (non-listed speed grade))
- Non-volatile flash configuration storage (vs SRAM-based small FPGAs (e.g. Lattice MachXO2))
Design Notes
The EPM240T100I5 requires a clean 3.3V core supply and supports 1.5V/1.8V/2.5V/3.3V on its I/O banks via MultiVolt. Place a 100 nF decoupling capacitor within 5 mm of every VCC pin and a bulk 10 uF tantalum or ceramic on the 3.3V plane. Power-on ramp should be monotonic; reset behavior is undefined if VCC drops below 2.0V momentarily. Use a dedicated LDO (e.g. TLV1117-3.3) rather than sharing a switching regulator with the host MCU.
Route all JTAG signals (TCK, TMS, TDI, TDO) with 50-ohm controlled impedance and keep trace length under 50 mm if the JTAG chain includes more than two devices. Place the JTAG connector within 100 mm of the CPLD to avoid signal-integrity issues during in-system programming. Leave the nCONFIG and nSTATUS pins accessible for factory programming, even if unused in the final design, to support field recovery.
Do not assume EPM240 density variants (EPM240G, EPM240F) are pin-compatible with the standard EPM240 in all packages - vertical migration is supported in TQFP-100, but pinout shifts in larger packages such as the 256-pin FineLine BGA. Always verify against the MAX II Device Handbook vertical-migration table. Also note that the MAX II family has entered NRND status on some channels - design with second-source in mind by selecting the EPM240T100I5N (lead-free, broader availability).
Compliance Information
Compliance data not in verified web data. The lead-free N-suffix variants (EPM240T100I5N) are documented as Pb-free. MAX II family is not AEC-Q100 qualified; for automotive designs, verify with manufacturer or select a Q100-qualified CPLD family.
