AT89S8253-24JU details

Basic Information

· Chip Type: The AT89S8253-24JU is an 8-bit CMOS microcontroller belonging to the AT89S series by Atmel (now Microchip Technology).

· Package Type: It adopts a 44-pin Plastic Leaded Chip Carrier (PLCC) package, which offers excellent electrical performance and mechanical stability, making it suitable for surface mounting on various printed circuit boards.

Performance Parameters

· Storage Capacity: It features 12KB of In-System Programmable (ISP) flash program memory and 2KB of EEPROM (Electrically Erasable Programmable Read-Only Memory) data memory. These can be used to store program codes and important data, facilitating in-system program updates and modifications during operation.

· Operating Speed: It can reach a maximum operating frequency of 24MHz, enabling fast instruction execution to meet the requirements of various applications with high real-time performance needs.

· Operating Voltage: The typical operating voltage range is 2.7V to 5.5V, providing a wide voltage adaptation range to ensure stable operation in different power supply environments.

· Temperature Range: The operating temperature range is -40°C to 85°C, making it suitable for a variety of industrial and commercial application environments with good environmental adaptability.

Functional Features

· Instruction Set: It is compatible with the industry-standard MCS-51 instruction set and pinout. This means it can be easily interchanged and work collaboratively with other chips based on the MCS-51 architecture, reducing development costs and difficulties.

· Communication Interfaces: It integrates SPI (Serial Peripheral Interface) and UART/USART (Universal Asynchronous Receiver/Transmitter / Universal Synchronous Asynchronous Receiver/Transmitter) communication interfaces, facilitating high-speed data transmission and communication with other devices such as sensors, displays, and storage devices.

· Internal Resources: It includes 3 timers/counters, which can be used for timing, counting, pulse width modulation, and other functions. It also has a power-on reset circuit to ensure the chip initializes correctly and enters normal operation when the power is turned on.

Application Fields

· Industrial Control: It can be used in various industrial automation equipment, controllers on production lines, etc., to achieve precise control and monitoring of production processes.

· Consumer Electronics: Such as smart home devices, intelligent toys, video game consoles, etc., enabling various complex control functions and human-machine interaction interfaces.

· Instruments and Meters: In various measuring instruments and meters, it is used for data collection, processing, and display, improving the accuracy and intelligence of the instruments.

· Communication Equipment: It can serve as a control unit in communication devices to handle communication protocols and control data transmission.
