AT89S51-24JU Description

Short technical summary and product information.

The AT89S51-24JU is a low-power, high-performance CMOS 8-bit microcontroller from Microchip Technology, based on the industry-standard 8051 architecture. It offers 4KB of In-System Programmable (ISP) Flash memory, allowing for in-system reprogramming. The device includes 128 Bytes of internal RAM and 32 programmable I/O lines.

 

Key electrical specifications include an operating voltage range of 4.0V to 5.5V and a maximum clock frequency of 33 MHz, with a speed rating of 24MHz. It features an internal oscillator and supports low-power Idle and Power-down modes. The microcontroller is equipped with two 16-bit timer/counters, a full-duplex UART serial channel, and a watchdog timer.

 

This component is housed in a 44-PLCC (Plastic Leaded Chip Carrier) package, suitable for surface mounting. It operates within an industrial temperature range of -40°C to 85°C. The AT89S51 is designed for cost-effective embedded control applications requiring a versatile and powerful 8-bit MCU.
