    Products Detail

    The TSC80251G2D derivatives are pin and software compatible with standard 80C51/Fx/Rx/Rx+ with extended on-chip data memory (1Kbyte RAM) and up to 256kilobytes of external code and data. Additionally, the TSC83251G2D and TSC87251G2D provide on-chip code memory: 32 kilobytes ROM and 32 kilobytes EPROM/OTPROM respectively. They provide transparent enhancements to Intel’s 8xC251Sx family with an additional Synchronous Serial Link Controller (SSLC supporting TWI, 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.
