DESCRIPTION
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. Typical APPLICATIONS
