LPC1100 ARM Cortex-M0 CAN microcontrollers

NXP has introduced the first two devices, LPC11C12 and LPC11C14, in its LPC11C00 series featuring a Controller Area Network (CAN) 2.0B-compliant controller for industrial and embedded networking applications.
CAN can be price prohibitive for low cost embedded applications, but NXP says its LPC11C00 series provides a new low cost entry point and total CAN solution.
Traditionally used primarily in automotive applications, NXP says the CAN bus is now one of the best choices for embedded networking applications which require communication across multiple embedded microcontrollers and CAN device nodes such as sensors and actuators. Some of today's new market demands are embedded machine control applications such as home appliances, motor controllers and elevator systems, as well as energy and power controllers that increasingly need to communicate with each other. One recent example is a high end coffee machine using microcontrollers interconnected via CANopen.
Incorporating CANopen drivers in on chip ROM provides design engineers with API commands to the CANopen protocol, enabling rapid integration of the LPC11C00 series into CAN based networks. These drivers provide defined CAN and CANopen APIs to simplify CAN application development.
Drivers are incorporated in low power ROM, freeing up to 8kB of user code space and offering reduced operating power, as well as secure and safe bootloads via CAN or other on chip serial channels. With the security and peace of mind of ROM based drivers, updating Flash via In System Programming (ISP) over the CAN-bus provides functionality from programming blank parts in production through changing system parameters to full infield reprogrammability.
According to NXP, the LPC11C00 requires 40 to 50% smaller code size than 8/16bit microcontrollers for most common microcontroller tasks. This is enabled by the powerful Cortex-M0 v6-M instruction set which is built on a fundamental base of 16bit Thumb instructions unique to 32bit microcontrollers today.
