The LPC11E6x family is available in three memory and package variations, including up to 256 kB Flash, 36 kB RAM and 4 kB EEPROM. Power efficiency is achieved through an ARM Cortex-M0+ core and NXP’s power profiles that allow various power saving options depending on the application demands. High-precision analogue features include a 2 Msamples/sec, 12-channel, 12-bit ADC, and connectivity is provided through I 2C and SPI interfaces, USARTs, and up to 80 GPIOs.
Also new to the LPC1100 Series, the LPC11E6x's two on-chip SCTimer/PWMs support advanced timing features. This unique block can operate like most traditional timers, and includes a state machine to give programmers a higher degree of timing control and programmability. It can be configured as multiple PWMs, a PWM with dead-time control, a PWM with reset capability, and many other functions that cannot be duplicated with traditional timers. NXP’s SCTimer/PWM Cookbook provides a collection of examples and usage notes to help programmers quickly implement popular timing functions for LPC11E6x applications.
The LPC portfolio now includes 136 microcontrollers qualified for use at 105C, including all LPC800, LPC1800, and LPC4300 devices. Many existing LPC1100 parts have also been re-qualified to 105C, since originally released, including LPC11U6x, LPC11E6x, and LPC111x MCUs.
