AT89S52-24PU 8KB 4V~5.5V 256Byte 24MHz FLASH 32 DIP-40 Microcontroller IC

Description

AT89S52-24PU 8KB 4V~5.5V 256Byte 24MHz FLASH 32 DIP-40 Microcontroller IC The AT89S52-24PU is a high-performance, low-power CMOS 8-bit microcontroller from Atmel, built around an 80C51 core. It is fully compatible with the industry-standard MCS-51 instruction set and pinout, making it a versatile and easy-to-upgrade solution for existing designs. This microcontroller is manufactured using Atmel’s high-density nonvolatile memory technology, integrating a powerful 8-bit CPU with programmable Flash memory on a single monolithic chip. This integration provides a highly-flexible and cost-effective foundation for a wide range of embedded control applications. At the heart of the device is 8KB of In-System Programmable (ISP) Flash memory, which allows the program memory to be reprogrammed in-circuit or by a conventional programmer, offering immense flexibility during development and production. The chip also contains 256 bytes of internal RAM for data storage and operation. It supports a fully static operation mode from 0 Hz up to 24 MHz, enabling designs to optimize for power consumption by scaling the clock speed down to a complete halt without losing data. The microcontroller is equipped with a rich set of integrated peripherals, including 32 programmable I/O lines, three 16-bit timer/counters, a full-duplex UART serial channel, and a watchdog timer. It also supports advanced power management through two software-selectable power-saving modes: Idle Mode, where the CPU is halted while peripherals remain active, and Power-down Mode, which freezes the oscillator to minimize energy consumption until the next interrupt or reset, making it suitable for battery-powered applications.
