NXP 50-MHz, 32-bit
Cortex-M0™ microcontrollers
LPC1100
Cortex-M0 based microcontrollers with
industry-leading power and efficiency
Built around the new Cortex-M0 architecture, the smallest, lowest power, and most energy-efficient
ARM core ever developed, these MCUs are ideally equipped for use in many traditional 8/16-bit
applications.

NXP’s LPC1100 is the lowest-priced 32-bit MCU solution
in the market. It offers greater value than existing 8/16-bit
microcontroller by delivering unprecedented performance,
simplicity, low power, and dramatic reductions in code size for
every application.
With over 45 DMIPS of performance compared to the
sub-DMIP performance typical of 8-bit MCUs and 3 to 5 DMIPS
for 16-bit MCUs, the LPC1100 not only execute basic control
tasks but sophisticated algorithms as well, making even the
most complex tasks within reach. Using less time to do more
tasks translates directly into lower energy consumption.
This level of performance is delivered at 50 MHz, with extensive
power optimization, at less than 10 mA.
Challenging the belief that 8/16-bit microcontrollers use less
code, industry-standard Coremark benchmarks show that
the LPC1100 requires 40-50% less code for most common
microcontroller tasks.
