LPC8N04 is a cost-effective MCU which serves as an entry-level connectivity solution for embedded applications with integrated NFC connectivity. The LPC8N04 MCU contains multiple features, including several power-down modes and a selectable CPU frequency of up to 8 MHz for ultra-low power consumption. The peripheral complement of the LPC8N04 MCU includes 32 kB of flash memory, 8 kB of SRAM, 4 kB of EEPROM, one I2C, one SPI/SSP, and up to 12 general purposes I/O pins.
