The AT89S51-24PU is an 8-bit microcontroller based on the industry-standard 8051 core architecture, manufactured by Microchip Technology. It integrates 4KB of In-System Programmable Flash memory with 10,000 write/erase cycles endurance, 128 bytes of internal RAM, and 32 programmable I/O lines. The device operates at a maximum clock frequency of 24MHz and supports a supply voltage range of 4V to 5.5V.
Key peripherals include two 16-bit timer/counters, a full-duplex UART serial channel, a watchdog timer, and dual data pointers. The microcontroller also features low-power idle and power-down modes, with interrupt recovery from power-down. It is designed for static operation down to zero frequency.
The AT89S51-24PU is housed in a 40-pin PDIP (Plastic Dual In-line Package) with a 0.600-inch row spacing, suitable for through-hole mounting. It operates over an industrial temperature range of -40°C to +85°C. This microcontroller is ideal for embedded control applications requiring a cost-effective, flexible solution with in-system programmability.
