    Intro to Low-Power Cortex-M0 LPC1100 MCU (NXP eLearning)


The LPC11D14 is a ARM Cortex-M0 based, low-cost 32-bit MCU family, designed for 8/16-bit microcontroller applications, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures. The LPC11D14 is a dual-chip module consisting of a LPC1114 single-chip microcontroller combined with a PCF8576D Universal LCD driver in a low-cost 100-pin package. The LCD driver provides 40 segments and supports from one to four backplanes. Display overhead is minimized by an on-chip display RAM with auto-increment addressing.

Features and benefits

  • 40-Segment LCD driver
  • One to four backplanes
  • On-chip display RAM with auto-increment addressing
  • ARM Cortex-M0 processor, running at frequencies of up to 50 MHz
  • ARM Cortex-M0 built-in Nested Vectored Interrupt Controller (NVIC)
  • Serial Wire Debug
  • System tick timer
  • 32 kB on-chip flash programming memory
  • 8 kB SRAM
  • In-System Programming (ISP) and In-Application Programming (IAP)
  • 42 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors
  • GPIO pins can be used as edge and level sensitive interrupt sources
  • High-current output driver (20 mA) on one pin
  • High-current sink drivers (20 mA) on two I2C-bus pins in Fast-mode Plus
  • Four general purpose counter/timers
  • Programmable windowed WDT
  • 10-bit ADC with input multiplexing among 8 pins
  • UART with fractional baud rate generation, internal FIFO, and RS-485 support
  • Two SPI controllers with SSP features
  • I2C-bus interface supporting full I2C-bus specification and Fast-mode Plus
  • 12 MHz internal RC oscillator trimmed to 1 % accuracy
  • Crystal oscillator with an operating range of 1 MHz to 25 MHz
  • Programmable watchdog oscillator with a frequency range of 7.8 kHz to 1.8 MHz
  • PLL allows CPU operation up to the maximum CPU rate
  • Clock output function with divider
  • Integrated PMU (Power Management Unit)
  • Power profiles residing in boot ROM allowing to optimize performance
  • Three reduced power modes: Sleep, Deep-sleep, and Deep power-down
  • Processor wake-up from Deep-sleep
  • Power-On Reset (POR)
  • Brownout detect with four separate thresholds for interrupt and forced reset
  • Unique device serial number for identification
  • Single power supply (1.8 V to 3.6 V)
