TSC87251G1A-16IA Overview

Extended 8?bit Microcontroller with Serial Communication

TSC87251G1A
Extended 8–bit Microcontroller with Serial Communication
Interfaces
1. Description
The TSC87251G1A products are derivatives of the
T
EMIC
Microcontroller family based on the extended
8–bit C251 Architecture. This family of products is
tailored to 8–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.
The TSC87251G1A derivatives are pin–out and
software compatible with standard 80C51/Fx/Rx with
extended on–chip data memory (1 Kbyte RAM),
on–chip memory (16 Kbytes EPROM/OTPROM) and
up to 256 Kbytes of external code and data.
They provide transparent enhancements to Intel’s
87C251Sx family with an additional Synchronous Serial
Link Controller (SSLC supporting I
2
C,
µWire
and SPI
protocols), a Keyboard interrupt interface and Power
Monitoring and Management features.
Notes:
This Datasheet provides the technical description of the TSC87251G1A derivatives. For further information on the device usage, please request
the TSC80251 Programmers’ Guide and the TSC80251G1 Design Guide.
For information on the Mask ROM and ROMless devices, please refer to the TSC87251G1D Datasheet.
