AT89S52-24AUR Description

Short technical summary and product information.

The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory. It is compatible with the industry-standard 80C51 instruction set and pinout. Key features include 8KB Flash, 256 bytes of RAM, 32 programmable I/O lines, three 16-bit timer/counters, a full duplex UART serial channel, a watchdog timer, dual data pointer, and two power saving modes (Idle and Power-down). The device operates from 4V to 5.5V and has a fully static operation from 0 Hz to 33 MHz. The operating temperature range is -40°C to 85°C. The part is supplied in a 44-TQFP (10x10 mm) surface mount package. This microcontroller is suitable for a wide range of embedded control applications requiring a cost-effective 8051-compatible solution.
