Extended temperature range for ARM Cortex-M0+ based MCUs

April 04, 2014 // By Graham Prophet
Giving you a wider choice for extreme industrial environments, NXP Semiconductors has added LPC microcontrollers rated for temperatures up to 105C. The LPC11E6x family is designed for harsh operating conditions common in many industrial, lighting, and industrial automation applications.

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.

LPC11E6x key features include;

ARM Cortex M0+ core, operating at frequencies up to 50 MHz

Up to 4 kB EEPROM, 256 kB Flash, and 36kB RAM

High-precision analogue: two Msps, 12-channel, 12-bit ADC and temperature sensor

Timing subsystem: two SCTimer/PWMs, four multi-purpose timers, and real-time clock (RTC)

Connectivity: two I 2C interfaces, two SPI interfaces, up to 5 USARTs, up to 80 GPIO pins

DMA controller

CRC engine

ROM drivers for Power Profiles

Software- and tool-compatible with existing LPC11U/Exx and LPC134x parts

Device prices begin at $2.03 (10,000). The LPC11U6x LPCXpresso board is used as the development platform for the LPC11E6X family.
