89S52 Atmel Microcontroller IC

The AT89S52 designed as a effectively low-power, high-performance CMOS 8-bit microcontroller. It comes with 4K bytes of in-system programmable non-volatile storage manufactured using Atmel’s high-density non-volatile memory technology. Meanwhile, it is compatible with the industry-standard 80C51 instruction set and pinout. The on-chip Flash on the chip permits the program memory to be reprogrammed in-system.  Or via a standard non-volatile memory programmer.

In this Atmel microcontroller,  by combining a flexible 8-bit CPU with in-system programmable Flash on a monolithic chip, 89S52 becomes effectively powerful microcontroller. In order that it delivers a highly flexible and affordable solution to various embedded control applications. Moreover, the AT89S52 features 4K bytes of Flash, 128 bytes of RAM, 32 I/O lines, Watchdog timer, two data pointers, two 16-bit timer/counters. And also equipped with five vector two-level interrupt architecture, a full-duplex serial port interface, on-chip oscillator, and clock circuitry.

In addition to it, the AT89S52 equipped with static logic for operation right down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the functioning of the CPU allowing the RAM, timer/counters, serial port, and interrupt system to continue their operation. Whereas, 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. These two features makes it suitable for battery operated applications. The main drawback of this microcontroller is absence of an in-built ADC and does not support SPI or I2C protocols.
