is at89c2051 microcontroller avalaible in multisim
The Atmel AT89 series is an Intel 8051-compatible family of 8 bit microcontrollers ( Cs) manufactured by the Atmel Corporation.
Based on the Intel 8051 core, the AT89 series remains very popular as general purpose microcontrollers, due to their industry standard instruction set, and low unit cost. This allows a great amount of legacy code to be reused without modification in new applications. While considerably less powerful than the newer AT90 series of AVR RISC microcontrollers, new product development has continued with the AT89 series for the aforementioned advantages.
More recently, the AT89 series has been augmented with 8051-cored special function microcontrollers, specifically in the areas of USB, I C (two wire interface), SPI and CAN bus controllers, MP3 decoders and hardware PWM.
AT89C2051 Microcontroller - 20-pin DIP
Description
The AT89C2051 is a low-voltage, high-performance CMOS 8-bit microcomputer with 2K bytes of Flash programmable and erasable read only memory (PEROM). The device is manufactured using Atmel s high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C2051 is a power-ful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications.
