The AT89C2051-12SI is an 8-bit microcontroller based on the industry-standard 8051 core. It integrates 2KB of Flash program memory and 128 bytes of RAM, making it suited for compact embedded control applications. The device is supplied by Microchip Technology in a 20-SOIC surface-mount package.
The microcontroller provides 15 programmable I/O lines, a UART/USART serial interface for communication, and an internal oscillator. It operates at a clock frequency of 12 MHz and requires a supply voltage between 4V and 6V. The operating temperature range is -40°C to 85°C, allowing use in industrial environments.
With its on-chip peripherals, including LED drive capability, the AT89C2051-12SI is appropriate for simple control tasks, such as LED interfacing and serial communication applications. Its static CMOS design supports fully static operation, and the small SOIC package helps conserve board space in embedded designs.
The supply voltage range is 4V to 6V.
It comes in a 20-SOIC (0.295", 7.50mm Width) surface-mount package.
