Description
The TSC80251G2D products are derivatives of the Atmel Microcontroller family based on the 8/16-bit C251 Architecture. This family of products is tailored to 8/16-bit microcontroller applications requiring an increased instruction throughput, a reduced operating frequency or a larger addressable memory space. The architecture can provide a significant code size reduction when compiling C programs while fully preserving the legacy of C51 assembly routines.
