LPC2458 - Single-chip 16-bit/32-bit micro
NXP Semiconductors designed the LPC2458 microcontroller around a 16-bit/32-bit ARM7TDMI-S CPU core with real-time debug interfaces that include both JTAG and embedded trace.
The LPC2458 has 512 kB of on-chip high-speed flash memory.
This flash memory includes a special 128-bit wide memory interface
