LPC2124FBD64

Product Summary

The LPC2124FBD64 is a Single-chip 16/32-bit microcontroller. The LPC2124FBD64 is based on a 16/32 bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 128/256 kilobytes (kB) of embedded high speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at maximum clock rate. For critical code size applications, the alternative 16-bit Thumb. Mode reduces code by more than 30 % with minimal performance penalty.
