LPC2478FET208,551 (NXP)

The LPC2478FET208,551 is a 16-bit/32-bit Microcontroller based on ARM7TDMI-S CPU core with real-time debug interfaces that include both JTAG and embedded trace. The LPC2478 has 512kB of on-chip high-speed flash memory. This flash memory includes a special 128-bit wide memory interface and accelerator architecture that enables the CPU to execute sequential instructions from flash memory at the maximum 72MHz system clock rate. This feature is available only on the LPC2000 ARM microcontroller family of products. The LPC2468 can execute both 32-bit ARM and 16-bit Thumb instructions. Support for the two instruction sets means engineers can choose to optimize their application for either performance or code size at the sub-routine 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.
