LPC2138FBD64/01,15

Product Summary

The LPC2138FBD64/01,15 is a single-chip 16/32-bit microcontroller. The LPC2138FBD64/01,15 microcontroller is based on a 32/16 bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combines the microcontroller with 32 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. The applicaitons of the LPC2138FBD64/01,15 include Automotive entertainment, Connectivity, Display, Communications gateways and protocol converters, Software modems, Voice recognition and Low-end imaging.
