Product details
Lattice Semiconductor LCMXO2-256HC-4SG32I - MachXO2 CPLD/FPGA
The LCMXO2-256HC-4SG32I is the industrial-temperature, 32-pin QFN version of the smallest MachXO2. Configuration lives in on-chip flash, so the 256 LUTs are active microseconds after power - the classic drop-in for glue logic, power-sequencing and bus control that used to need a CPLD, but with sysIO buffers spanning 1.2–3.3 V and hardened I2C/SPI/timer blocks.
Key Features
- 256 LUTs with on-chip configuration flash - instant-on, single chip
- Hardened 2× I2C, 1× SPI, 1× timer/counter, on-chip oscillator
- 2 kb distributed RAM; TransFR in-field update without I/O disruption
- sysIO buffers: LVCMOS/LVTTL, PCI, LVDS and other differential standards
- SG32 QFN, 27 user I/O, hot-socket I/O
- HC grade: internal regulator accepts 2.5 V or 3.3 V VCC

Frequently Asked Questions
Q: CPLD or FPGA?
A: MachXO2 is a flash-based FPGA positioned as a CPLD successor: LUT-based logic with non-volatile instant-on configuration - no external boot device, no configuration time.
Q: What differs from the -C commercial part?
A: Only temperature: this -I variant is qualified to -40…+100 °C junction; logic and timing are identical.
Q: Can I update logic in the field?
A: Yes - via JTAG/SPI/I2C, and TransFR updates the design while I/O hold state, keeping the board alive during the update.
