TSC80251G2D-24CB

Product Summary

The tsc80251g2d-24cb is a 16-Bit microcontroller with serial communication interface. The tsc80251g2d-24cb product is derivative of the Atmel Microcontroller family based on the 8/16-bit C251 Architecture. The tsc80251g2d-24cb 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 of the tsc80251g2d-24cb can provide a significant code size reduction when compiling C programs while fully preserving the legacy of C51 assembly routines. The applications of the tsc80251g2d-24cb include ISDN Terminals, High-Speed Modems, PABX (SOHO), Line Cards, DVD ROM and Players, Printers, Plotters, Scanners, Banking Machines, Barcode Readers, Smart Cards Readers, High-End Digital Monitors, High-End Joysticks, High-end TV’s.
