ATMEL The AT89C 4051 is a low-voltage, high-performance CMOS 8-bit microcontroller with4K bytes of Flash programmable and erasable read-only memory. The device is manufactured using Atmel’s high-density nonvolatile memory technology and iscompatible with the industry-standard MCS-51 instruction set. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C4051 is a powerfulmicrocontroller which provides a highly-flexible and cost-effective solution to manyembedded control applications.The AT89C4051 provides the following standard features: 4K bytes of Flash,128 bytes of RAM, 15 I/O lines, two 16-bit timer/counters, a five-vector, two-level interrupt architecture, a full duplex serial port, a precision analog comparator, on-chiposcillator and clock circuitry. In addition, the AT89C4051 is designed with static logicfor operation down to zero frequency and supports two software-selectable powersaving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters,serial port and interrupt system to continue functioning. The power-down mode savesthe RAM contents but freezes the oscillator disabling all other chip functions until thenext hardware reset.
