LPC122x Cortex-M0 Microcontrollers

NXP’s LPC122x Cortex-M0 microcontrollers add up to 128 kB flash, more analog and peripherals for customers’ applications

Image of NXP Semiconductor's LPC122x Cortex-M0 MicrocontrollersNXP expands its award-winning and low-power Cortex-M0 microcontroller offerings with the LPC122x series. The LPC122x series adds more features and performances to customers’ applications, including up to 128 kB of flash, DMA, CRC, 4 timers, RTC, comparators, ADC, Fast-Mode-Plus I2C, SPI and a Windowed Watch-dog timer. The LPC122x’s 128 kB flash supports an erase sector as small as 512 bytes. Its 12 MHz internal oscillator with 1 percent accuracy can optionally be used as a system clock output.

The LPC122x series also features the industry’s first division API function designed for the ARM Cortex-M0 Core. This eliminates the need of writing division codes in the software and improves the speed of a division by up to four times and greatly improves the system’s processing performance and saves code space. The LPC122x series is available in 48-LQFP and 64-LQFP packages.

In addition, the LPC122x series has an optional integrated 40 x 4 segment display driver, the LPC12D2x. This is the industry’s first Cortex-M0 microcontroller with an integrated display driver, allowing customers to further integrate their systems' components with smaller footprint and lower cost. LPC12D2x is available in 100-LQFP package.
