Product details

The NXP LPC3240FET296/01K is a 16/32-bit ARM9 microcontroller running at 266 MHz, built for applications that need a real-time control loop with a network stack on the same die. The ROMless program memory means all firmware lives on an external NOR/NAND Flash or EEPROM accessed through the EBI/EMI interface — the 256K × 8 SRAM serves as code scratchpad and data buffer, not persistent storage. That external memory bus is the critical design constraint: the board must carry a boot device and the layout must keep the parallel memory traces clean at 266 MHz.

The MCU includes DMA, I²S, motor control PWM, and a watchdog timer. Connectivity covers Ethernet, USB OTG, I²C, IrDA, Microwire, SPI, SSI, SSP, and UART/USART.

Supply voltage spans 0.9 V to 3.6 V.

Frequently asked questions

Can LPC3240FET296/01K be replaced by LPC3240FET296 without suffix?

Yes, the base part LPC3240FET296 (without /01K suffix) is the same silicon; the suffix indicates a factory-programmed configuration or test-code variant, not a die change.

Does LPC3240FET296/01K have external memory support for ROMless operation?

Yes, the ROMless program memory requires external NOR/NAND Flash or EEPROM accessed through the EBI/EMI interface; the 256K × 8 SRAM serves as working memory.

What is the recommended operating voltage for LPC3240FET296/01K?

The supply voltage range is 0.9 V to 3.6 V, allowing operation from a single Li-ion cell or a regulated 3.3 V rail.
