LPC800 Arm Cortex-M0+

Power Management

AC-DC Controllers with Integrated Power Switch


  • Arm® Cortex®-M0+ core running at frequencies of up to 8 MHz
  • Nested Vectored Interrupt Controller (NVIC)
  • Arm Serial Wire Debug (SWD)
  • System tick timer
  • IC reset input

Digital peripherals

  • Up to 12 General-Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors and repeater mode
  • GPIO pins which can be used as edge and level sensitive interrupt sources
  • High-current drivers/sinks (20 mA) on four GPIO pins
  • High-current drivers/sinks (20 mA) on two I2C-bus pins
  • Programmable Watchdog Timer (WDT)
  • Real-Time Clock (RTC) Timer

Communication interfaces

  • NFC/RFID ISO 14443 type A interface
  • Serial I2C-bus supporting full I2C-bus specification and Fast-mode with a data rate of 400 kbit/s, with multiple address recognition and monitor mode
  • SPI/SSP interface

Power control

  • Support for 1.72 V to 3.6 V external voltages
  • The LPC8N04 can also be powered from the NFC field
  • Activation via NFC
  • Integrated Power Management Unit (PMU) for versatile control of power consumption
  • Four reduced power modes for Arm Cortex-M0+: sleep, deep-sleep, deep power-down and battery-off
  • Power gating for each analog peripheral for ultra-low power operation
  • < 50 nA IC current consumption in Battery-off mode at 3.0 V
  • Power-On Reset (POR)
