TSC87251G1A
Extended 8âbit Microcontroller with Serial Communication
Interfaces
1. Description
The TSC87251G1A products are derivatives of the
TEMIC Microcontroller family based on the extended
8âbit C251 Architecture. This family of products is
tailored to 8âbit 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 pinâout and
software compatible with standard 80C51/Fx/Rx with
extended onâchip data memory (1 Kbyte RAM),
onâchip memory (16 Kbytes EPROM/OTPROM) and
up to 256 Kbytes of external code and data.
They provide transparent enhancements to Intelâs
87C251Sx family with an additional Synchronous Serial
Link Controller (SSLC supporting I2C, 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 Programmersâ Guide and the TSC80251G1 Design Guide.
For information on the Mask ROM and ROMless devices, please refer to the TSC87251G1D Datasheet.
