The AT89S51-24PC is a low-power, high-performance CMOS 8-bit microcontroller based on the industry-standard 8051 core. It integrates 4KB of in-system programmable Flash memory with 10,000 write/erase cycle endurance, 128 bytes of internal RAM, and 32 programmable I/O lines. The device operates at a supply voltage of 4V to 5.5V and supports a maximum speed of 24MHz (with datasheet indicating up to 33MHz).
Key peripherals include a full-duplex UART/USART serial channel, two 16-bit timer/counters, a watchdog timer (WDT), and six interrupt sources. The microcontroller also features low-power idle and power-down modes, with interrupt recovery from power-down. An internal oscillator eliminates the need for external clock components.
The AT89S51-24PC is housed in a 40-lead PDIP (plastic dual in-line package) with through-hole mounting, suitable for prototyping and industrial applications. Its operating temperature range is 0°C to 70°C. Common applications include industrial automation, consumer electronics, and medical devices.
The supply voltage range is 4V to 5.5V.
It comes in a 40-DIP (0.600", 15.24mm) package with through-hole mounting.
The operating temperature range is 0°C to 70°C (TA).
The part is listed as RoHS3 Compliant, but this is unverified and conflicts with manufacturer data.
It features an 8051 core running at 24MHz.
It has 4KB of Flash program memory and 128 bytes of RAM.
It has 32 I/O pins and supports UART/USART serial communication.
