AT89S52-24JU Description

Short technical summary and product information.

The AT89S52-24JU is an 8-bit microcontroller based on the industry-standard 8051 core, manufactured by Atmel. It features 8KB of in-system programmable Flash memory with 10,000 write/erase cycles and 256 bytes of internal RAM. The device operates at a maximum frequency of 24 MHz over a supply voltage range of 4V to 5.5V.

 

This microcontroller includes 32 programmable I/O lines, three 16-bit timer/counters, a full-duplex UART serial channel, and an SPI interface. It also integrates a watchdog timer, dual data pointer, and supports eight interrupt sources. Low-power operation is supported through Idle and Power-down modes.

 

The AT89S52-24JU is housed in a 44-pin PLCC (J-Lead) package with a plastic body and is designed for surface mount assembly. It is rated for an industrial temperature range of -40°C to 85°C, making it suitable for a wide variety of embedded control applications.
