General description
The LPC122x extend NXP's 32-bit ARM microcontroller continuum and target a wide
range of industrial applications in the areas of factory and home automation. Benefitting
from the ARM Cortex-M0 Thumb instruction set, the LPC122x have up to 50 % higher
code density compared to common 8/16-bit microcontroller performing typical tasks. The
LPC122x also feature an optimized ROM-based divide library for Cortex-M0, which offers
several times the arithmetic performance of software-based libraries, as well as highly
deterministic cycle time combined with reduced flash code size. The ARM Cortex-M0
efficiency also helps the LPC122x achieve lower average power for similar applications.
The LPC122x operate at CPU frequencies of up to 45 MHz.They offer a wide range of
flash memory options, from 32 kB to 128 kB. The small 512-byte page erase of the flash
memory brings multiple design benefits, such as finer EEPROM emulation, boot-load
support from any serial interface and ease of in-field programming with reduced on-chip
RAM buffer requirements.
The peripheral complement of the LPC122x includes a 10-bit ADC, two comparators with
output feedback loop, two UARTs, one SSP/SPI interface, one I2C-bus interface with
Fast-mode Plus features, a Windowed Watchdog Timer, a DMA controller, a CRC engine,
four general purpose timers, a 32-bit RTC, a 1 % internal oscillator for baud rate
generation, and up to 55 General Purpose I/O (GPIO) pins.
