Single-chip microcontroller, LPC2468FBD208K, NXP
The LPC2468FBD208K microcontroller is designed by NXP Semiconductors around a 32-bit ARM7TDMI-S CPU core with real-time debug interfaces, including both JTAG and embedded trace. It has 512 kB of on-chip high-speed flash memory. This flash memory includes a 128-bit wide memory interface and accelerator architecture that enables the CPU to execute sequential instructions from flash memory at the maximum 72 MHz system clock rate. The LPC2468FBD208K can execute both 32-bit ARM and 16-bit Thumb instructions, allowing engineers to optimize their application for either performance or code size at the subroutine level. When the core executes instructions in Thumb state, it can reduce code size by more than 30% with only a small loss in performance, while executing instructions in ARM state maximizes core performance.
Features
- CAN controller with two channels
- Standard ARM test/debug interface for compatibility with existing tools
- Emulation trace module supports real-time trace
- Two independent power domains allow fine tuning of power consumption based on needed features
- Each peripheral has its own clock divider for further power saving
- Brownout detect with separate thresholds for interrupt and forced reset
