The AT89S8252-24PI is an 8-bit microcontroller based on the industry-standard 8051 architecture, manufactured by Microchip Technology. It integrates 8KB of in-system reprogrammable Flash memory, 2KB of EEPROM with 100,000 write/erase cycles, and 256 bytes of internal RAM. The device operates over a supply voltage range of 4V to 6V and supports fully static operation from 0 Hz to 24 MHz.
Key peripherals include three 16-bit timer/counters, a programmable watchdog timer, nine interrupt sources, and a full-duplex UART serial channel. Connectivity is provided via SPI and UART/USART interfaces. The microcontroller also features low-power Idle and Power-down modes, dual data pointers, and a three-level program memory lock for code security.
The AT89S8252-24PI is designed for embedded control applications requiring robust 8051 compatibility. It is housed in a 40-pin PDIP package with through-hole mounting, making it suitable for prototyping and industrial environments. The operating temperature range is -40°C to 85°C, supporting industrial-grade applications.
The supply voltage range is 4V to 6V.
It is housed in a 40-pin DIP (0.600", 15.24mm) package, specifically a 40-PDIP.
The operating temperature range is -40°C to 85°C (TA).
RoHS status is conflicting: manufacturer page indicates non-compliant, while existing database indicates RoHS3 compliant. Verification is recommended.
It has 8KB (8K x 8) of Flash program memory.
The microcontroller supports SPI and UART/USART interfaces.
The device operates at up to 24 MHz with fully static operation from 0 Hz.
