Integrated CAN Transceiver

The LPC11C00 series are ARM® Cortex™-M0 based, low-cost 32-bit microcontrollers, designed for 8/16-bit microcontroller applications, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures. On-chip C_CAN drivers and flash In-System Programming tools via C_CAN are included. In addition, the LPC11C22 and LPC11C24 parts include an on-chip, high-speed CAN transceiver. Integrating the CAN transceiver on board increases system reliability and quality, reduces electrical interconnect and compatibility issues, and reduces board space by over 50 percent while adding less than 20 percent to the MCU cost.

Descriptive summary

On-Chip CAN and CANopen Drivers

On-chip CAN and CANopen drivers provide design engineers with easy-to-use API commands to the CANopen protocol. This enables rapid integration of the LPC11C00 into CAN-based networks which greatly simplifies the plug-and-play integration process. Furthermore, these drivers are incorporated in low-power ROM, freeing up to 8 kB of user code space. This offers the dual advantage of reduced operating power and secure and safe bootloading via CAN or other on-chip serial channels. With the security and peace of mind of ROM-based drivers, flash updating can be done via In System Programming (ISP) over the CAN-bus. This gives you the entire range of functionality, from programming blank parts in production through to changing system parameters to full, in-field re-programmability.

Enabling Higher Code Density

The LPC11C00 enables 40 to 50 percent smaller code sizes compared to traditional 8-/16-bit microcontrollers for most common microcontroller tasks. This is achieved through the powerful Cortex-M0 v6-M instruction set, which is built on a fundamental base of 16-bit Thumb instructions and unique to 32-bit microcontrollers today.

Superior Performance

With over 45 DMIPS of performance, the LPC11C00 provides powerful message and data handling for CAN device nodes. This is while offering power optimization unavailable in today's 8-/16-bit microcontrollers.
