LPC2138FBD64

Product Summary

The LPC2138FBD64 microcontroller is based on a 32/16 bitARM7TDMI-S CPU with real-time emulation and embedded trace support, that combines the LPC2138FBD64 with 32 kB, 64 kB, 128 kB, 256 kB and 512 kB of embedded high speed Flash memory. Due to its tiny size and low power consumption, the LPC2138FBD64 is ideal for applications where miniaturization is a key requirement, such as access control and oint-of-sale.
