TSC80251G2D 8/16-bit Microcontroller Interfaces 1. Description The TSC80251G2D products are derivatives of the TEMIC 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 C.

TSC80251G2D 8/16-bit Microcontroller Interfaces 1. Description The TSC80251G2D products are derivatives of the TEMIC 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. 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, the TSC83251G2D and TSC87251G2D provide on-chip code memory: 32 Kbytes ROM and 32 Kbytes EPROM/ OTPROM respectively. They provide transparent enhancements to Intel’s 8xC251Sx family with an additional Synchronous Serial Link Controller (SSLC supporting I2C, µWire and SPI protocols), a Keyboard interrupt interface, a dedicated Baud Rate Generator for UART, and Power Management features. TSC80251G2D derivatives are optimized for speed and for low power consumption on a wide voltage range. with Serial Communication Note: This Datasheet provides the technical description of the TSC80251G2D derivatives. For further information on the device usage, please request the TSC80251 Programmer’s Guide and the TSC80251G1D Design Guide. 2.
