AT89S52 8 Bit Microcontroller DIP Mount
The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K
Bytes of Flash memory. The device is manufactured with
Atmel's high-density nonvolatile memory technologies and is compatible with all the industry-standard
80C51 instruction set and pinout. The on-chip Flash allows the program
Memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer.
By combining a versatile 8-bit CPU using programmable Flash on a single chip, the Atmel AT89S52 is a powerful microcontroller which provides a Cost-effective and highly-flexible alternative to a lot of embedded control applications.
The following standard features: 8K bytes of Flash, 256 bytes are provided by the AT89S52 Of RAM, 32 I/O traces, Watchdog timer, two data pointers, three 16-bit timer/counters, a Interrupt design, a full duplex serial port, on-chip oscillator, And clock circuitry. Additionally, the AT89S52 is designed with static logic for operation
The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port, and Interrupt system to continue functioning. The Power-down mode saves the RAM contents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset.
