The AT89S51-24AU is an 8-bit microcontroller based on the 8051 core architecture from Microchip Technology. It operates at a maximum frequency of 24MHz and features 4KB of Flash program memory and 128 bytes of RAM. The device integrates 32 general-purpose I/O pins, a UART serial interface, and a watchdog timer for system reliability.
This microcontroller supports a wide supply voltage range of 4V to 5.5V and draws a nominal supply current of 25mA. It includes two 16-bit timers/counters and an internal oscillator, eliminating the need for external clock components. The access time is 24µs, suitable for moderate-speed control applications.
The AT89S51-24AU is housed in a 44-pin TQFP package with a 10x10mm body and 1.05mm height, designed for surface-mount assembly. It operates over an industrial temperature range of -40°C to 85°C, making it suitable for harsh environments. The device is lead-free and RoHS compliant.
