The AT89S51-24PI is an 8-bit microcontroller featuring 4KB of In-System Programmable (ISP) Flash memory, which supports up to 10,000 write/erase cycles. It operates within a voltage range of 4.0V to 5.5V and is capable of fully static operation at frequencies from 0 Hz to 33 MHz. The microcontroller includes 128 bytes of internal RAM, 32 programmable I/O lines, two 16-bit timer/counters, and a full duplex UART serial channel. It also supports six interrupt sources and features a watchdog timer, dual data pointers, and a power-off flag. The device is designed for low power consumption, offering idle and power-down modes to enhance energy efficiency. The AT89S51-24PI is compatible with MCS-51 products and provides flexible ISP programming options in both byte and page modes. It is available in green packaging, free from lead and halides, making it suitable for environmentally conscious applications. This microcontroller is a versatile choice for various embedded control applications, combining performance and flexibility in a compact form factor.
