16 KB Flash and 4 KB RAM fit firmware for a USB HID report descriptor or a Modbus RTU slave. 72 MHz core handles USB interrupts while scanning the 8-channel ADC at 10-bit resolution.
Active product status with no announced last-time-buy. Sourced through independent distribution and quoted to order against an RFQ.
Within the LPC13xx series, the LPC1343FHN33 (with 32 KB Flash) is pin-compatible and offers double the program memory, though the RAM remains 4K x 8. Verify the firmware fits before swapping.
It is rated for -40°C to 85°C, covering industrial environments, outdoor telecom cabinets, and automotive cabin applications.
Yes, it integrates a USB 2.0 full-speed device controller alongside I²C, SPI, UART, and SSP.
