General description

The NXP LPC8N04 is an IC optimized for an entry level Cortex-M0+ MCU with built-in NFC interface. LPC8N04 supports an effective system solution with a minimal number of external components for NFC related applications. The embedded ARM Cortex-M0+ offers flexibility to the users of this IC to implement their own dedicated solution. The LPC8N04 contains multiple features, including multiple power-down modes and a selectable CPU frequency of up to 8 MHz, for ultra-low power consumption.
