LPC1224
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.
