AT89S52-24JU Description

Short technical summary and product information.

The Microchip AT89S52-24JU is a high-performance CMOS 8-bit microcontroller based on the industry-standard 80C51 architecture. It integrates 8KB of in-system programmable Flash memory with 10,000 write/erase cycle endurance and 256 bytes of internal RAM. The device operates at clock frequencies up to 24MHz and supports 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. On-chip peripherals include a watchdog timer and an internal oscillator. The device supports low-power Idle and Power-down modes for energy-sensitive applications.

 

The AT89S52-24JU is housed in a 44-pin PLCC (J-Lead) package designed for surface mount assembly. It is rated for an industrial temperature range of -40°C to 85°C, making it suitable for demanding environments. The part is RoHS compliant and lead-free.
