The AT89S51-24JU is an integrated circuit (IC) component manufactured by Atmel Corporation. This IC is a member of the 8051 family of microcontrollers and is widely used in various applications.
Here are some key features of the AT89S51-24JU:
1. Microcontroller Architecture: The AT89S51-24JU follows the Harvard architecture and is based on the popular 8051 instruction set. It features an 8-bit CPU and comes with built-in peripherals.
2. CPU Speed: The IC operates at a maximum CPU speed of 24 MHz. This allows for efficient execution of instructions, making it suitable for real-time applications.
3. Memory: It has a total addressable memory space of 64KB, divided into 4KB of on-chip flash program memory and 128 bytes of on-chip RAM (Random Access Memory). The program memory is non-volatile, allowing the storage of user programs even after power-off.
4. Communication Interfaces: The AT89S51-24JU supports several communication interfaces, including a full-duplex UART (Universal Asynchronous Receiver-Transmitter) and a two-wire serial interface (I2C). These interfaces enable connectivity with other external devices.
5. I/O Ports: It has four 8-bit bidirectional I/O ports (P0, P1, P2, P3), providing a total of 32 programmable I/O pins
