The 8051 (also known as MCS-51) is an MCU design from the 80's that remains popular today. Modern 8051-compatible microcontrollers are available from multiple vendors, in all shapes and sizes, and with a wide range of peripherals. In this instructable we will be looking at the AT89C2051 MCU from Atmel. AT89C2051 is a small (2Kbyte Flash, 128byte RAM), cheap (~$1.40 per chip) microcontroller. Features: • 2.7-6V operation • 15 I/O lines • 2 timers (16 bit) • Internal and external interrupts • UART • On-chip analog comparator • Up to 2MIPS with a 24MHz clock. Previous super bowls.

The PG2051 is a development programmer for the ATMEL AT89C2051. The AT89C2051 programmer is fast, small and simple to use. Makkal tv nethaji serial title song. In normal use device programming consists of: Insert an 89C2051 - (Manual Test if desired). - but remember to get the software from Atmel.
