The ATMEL 8-Bit 8051 Microcontroller is a low-voltage, high-performance CMOS microcomputer featuring 2kB of flash programmable and erasable read-only memory (PEROM). Manufactured using ATMEL's high-density non-volatile memory technology, this device is fully compatible with the industry-standard MCS-51 instruction set. By combining a versatile 8-bit CPU with flash memory on a monolithic chip, this microcontroller provides a highly flexible and cost-effective solution for a wide range of embedded control applications.
This powerful microcontroller includes several standard features to support complex operations. It offers 128 bytes of RAM, 15 programmable I/O lines, and two 16-bit timer/counters. Additionally, it incorporates a five-vector, two-level interrupt architecture, a full duplex serial port, and a precision analogue comparator. The on-chip oscillator and clock circuitry ensure streamlined integration into your designs.
Designed with static logic, the device operates down to zero frequency and supports two software-selectable power-saving modes, making it suitable for power-sensitive applications. Direct LED drive outputs and a programmable serial UART channel further enhance its versatility for industrial environments.
