AT89S52, 8-Bit Microcontroller, SMD

The AT89S52 is a low-power, high-performance 8-bit CMOS microcontroller from Atmel (now Microchip Technology). Based on the MCS-51 architecture, it integrates 8KB of in-system programmable Flash memory, 256 bytes of RAM, and 32 programmable I/O lines, making it ideal for embedded control applications.

With a maximum clock speed of 33MHz, the AT89S52 is designed to handle fast data processing. It features three 16-bit Timer/Counters, an enhanced full-duplex UART, and a six-vector two-level interrupt system, providing advanced multitasking capabilities.

The on-chip oscillator and clock circuitry simplify design and development, while programmable power-saving modes (Idle and Power-Down) allow for battery-efficient applications.

The AT89S52 microcontroller is available in an SMD (Surface-Mount Device) package, making it suitable for compact designs, industrial automation, and consumer electronics. It is a cost-effective and reliable solution for projects requiring high-speed processing, flexible interfacing, and low power consumption.
