NXP Semiconductors designed the LPC2478 microcontroller, powered by the

ARM7TDMI-S core, to be a highly integrated microcontroller for a wide range of

applications that require advanced communications and high quality graphic displays. The

LPC2478 microcontroller has 512 kB 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 72 MHz system clock rate. This feature is available only on the LPC2000 ARM

microcontroller family of products. The LPC2478, with real-time debug interfaces that

include both JTAG and embedded trace, can execute both 32-bit ARM and 16-bit Thumb

instructions.
