LPC2148FBD64

Product Summary

The LPC2148FBD64 is a microcontroller. It is based on a 32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combines the LPC2148FBD64 with embedded high-speed flash memory ranging from 32 kB to 512 kB. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty. Due to its tiny size and low power consumption, the LPC2148FBD64 is ideal for applications where miniaturization is a key requirement, such as access control and point-of-sale.
