  • ARM® Cortex®-M0+ at up to 30 MHz and up to 64KB flash
  • Integrated NFC connectivity
  • Scalable differentiated peripheral options
  • Flexible Package Options: TSSOP, LQFP, QFN, XSON (tiny)

NXP’s LPC800 series MCUs offer a range of low-power, space efficient, low-pin-count options for basic microcontroller applications. Unique to low-end devices, the LPC800 series include differentiated product features, such as an NFC integration, mutual capacitive touch, switch matrix for flexible configuration of each I/O pin function, and patent-approved SCTimer/PWM, giving embedded developers unprecedented design-flexibility.

LPC8N04 combines NFC and MCU technology enabling energy harvesting and wireless communication for a diverse range of tagging and provisioning applications.
