Product Summary
The LPC2141FBD64 is a Single-chip 16-bit/32-bit microcontroller based on an ARM7TDMI-S CPU with real-time emulation and embedded trace support. The LPC2141FBD64 combines microcontroller with embedded high-speed flash memory ranging from 32 kB to 512 kB. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty.
