The AT89S51-24JI is an 8-bit microcontroller from Atmel featuring an 8051 CPU core. It operates at clock frequencies up to 24MHz and comes with 4KB of on-chip flash program memory and 128 bytes of RAM. The device provides 32 I/O lines and supports UART/USART connectivity, along with a watchdog timer peripheral.
Designed for industrial temperature ranges from -40°C to 85°C, this CMOS microcontroller operates from a 4V to 5.5V supply. It includes an 8-bit external data bus and 16-bit address bus, suitable for expanded memory interface designs. The part is supplied in a 44-terminal PLCC (J-lead) package for surface mounting.
With no integrated ADC, PWM, DAC, or DMA channels, the AT89S51-24JI is best suited for basic control and communication tasks where simple 8-bit processing and I/O capabilities are required. Its internal oscillator type and industrial temperature grade make it appropriate for embedded control applications in harsh environments.
