Overview

The LPC11C14FBD48/30EL is an ARM Cortex-M0 based microcontroller featuring an integrated CAN 2.0B C-CAN controller and on-chip CANopen drivers. Operating at speeds up to 50MHz, it provides a cost-effective solution for industrial networking and automotive gateway applications requiring a small 48-LQFP footprint. It includes 32KB of Flash and 8KB of SRAM, with dedicated power management for low-power operation.

Why Choose This Part

This MCU integrates CANopen drivers directly into the on-chip ROM, significantly reducing the flash memory footprint required for communication stacks. It offers high-current 20mA sink capabilities on I2C pins for driving LEDs or high-speed buses directly. The inclusion of an internal RC oscillator trimmed to 1 percent accuracy allows for reduced BOM costs by eliminating external crystals in many timing-sensitive designs.

Applications

Industrial CAN Networks
Utilizing the integrated C-CAN controller and on-chip CANopen firmware to simplify industrial automation bus communication.
Automotive Gateways
Acting as a bridge between CAN nodes and other serial peripherals like I2C or UART in vehicle subsystems.
White Goods Control
Managing appliance logic and sensor interfacing using the 10-bit ADC and high-current I2C sink drivers.
System Supervisory Circuits
Monitoring power rails and system health using the built-in Brown-out Detect, POR, and Watchdog Timer.

Getting Started

Developers can use the NXP MCUXpresso IDE or third-party tools like Keil MDK and IAR Embedded Workbench. Firmware can be programmed via Serial Wire Debug (SWD) or by using the built-in In-System Programming (ISP) over UART. For evaluation, look for the OM13012 LPC11C24 LPCXpresso board which shares the same core architecture and CAN capabilities.
