Note: The datasheet of the AT89S52 Microcontroller and more detailed Features can be found at the bottom of this page. Since it is similar to the trust worthy architecture these microcontrollers are as per industry standard. The Microcontroller also has Operating mode, Idle Mode and Power down mode which makes it suitable for battery operated applications. However you can utilise external modules for the same. Atmel microcontroller can be programmed with different software's that is available in the market. Arduino, Keil uVision are the most used platforms to name a few.

WR P3. RD P3. The on-chip Flash allows the program memory to be user programmed by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C51RC is a powerful microcomputer which pro- vides a highly-flexible and cost-effective solution to many embedded control applications.
In addition, the AT89C51RC is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Power-down mode saves the RAM contents but freezes the oscillator, disabling all other chip functions until the next external interrupt or hardware reset. Pin Configurations 2.
