Microchip Technology AT89S51-24JUR is an 8-bit microcontroller featuring a robust 80C51 CPU core. This CMOS device operates at a maximum speed of 24MHz and offers 4KB of FLASH program memory, complemented by 128 bytes of on-chip data RAM. It supports an 8-bit external data bus and a 16-bit address bus, enabling access to external memory. The AT89S51-24JUR includes two 16-bit timers, a watchdog timer, and one UART for serial communication. With 32 general-purpose I/O lines and support for up to two external interrupts, it provides ample flexibility for embedded system designs. The device is housed in a 44-lead PQCC package and operates within a temperature range of -40°C to +85°C, with a supply voltage range of 5.0V to 5.5V. This component finds application in industrial control, consumer electronics, and automotive systems.
