Microchip Technology, Inc. Microcontrollers TS80C51RA2-LIB

The TS80C51RA2-LIB is an 8-bit microcontroller that is compatible with the 80C52 architecture, featuring 8051 pin and instruction compatibility. It operates at a maximum frequency of 40 MHz at 5V and 30 MHz at 3V, with an X2 speed improvement capability allowing for enhanced performance. The microcontroller includes four 8-bit I/O ports, three 16-bit timer/counters, and 256 bytes of scratchpad RAM. It offers on-chip ROM/EPROM options of 16K, 32K, or 64K bytes, along with expanded RAM (XRAM) options of 256 or 768 bytes. The device supports a programmable clock output, a programmable counter array with various functionalities including pulse width modulation and a hardware watchdog timer. It features a full duplex enhanced UART for serial communication, low EMI operation, and multiple power control modes, including idle and power-down modes to reduce power consumption. The TS80C51RA2-LIB is available in various packages, including PDIL40, PLCC44, and VQFP44, and operates within a temperature range of 0 to 70¬8C for commercial applications and -40 to 85¬8C for industrial applications. This microcontroller is suitable for applications requiring a robust and flexible 8-bit processing solution.
