TSC80251G2D
8/16-bit Microcontroller with Serial Communication
Interfaces
1. Description
The TSC80251G2D products are derivatives of the the TSC83251G2D and TSC87251G2D provide on-chip
TEMIC Microcontroller family based on the 8/16-bit code memory: 32 Kbytes ROM and 32 Kbytes EPROM/
C251 Architecture. This family of products is tailored OTPROM respectively.
to 8/16-bit microcontroller applications requiring an
They provide transparent enhancements to Intel’s
increased instruction throughput, a reduced operating
8xC251Sx family with an additional Synchronous Serial
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.

Link Controller (SSLC supporting I C, µWire and SPI
protocols), a Keyboard interrupt interface, a dedicated
Baud Rate Generator for UART, and Power Management
features.
The TSC80251G2D derivatives are pin and software
compatible with standard 80C51/Fx/Rx/Rx+ with
extended on-chip data memory (1 Kbyte RAM) and up
to 256 Kbytes of external code and data. Additionally,
TSC80251G2D derivatives are optimized for speed and
for low power consumption on a wide voltage range.
Note:
This Datasheet provides the technical description of the TSC80251G2D derivatives. For further information on the device usage, please request
