Option Description The AT89S52 is a low-power, high-performance CMOS 8-bit
microcontroller with 8K bytes of in-system programmable Flash
memory. The device is manufactured using Atmel’s high-density
nonvolatile memory technology and is compatible with 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 with in-system programmable Flash on a
monolithic chip, the Atmel AT89S52 is a powerful microcontroller
which provides a highly-flexible and cost-effective solution
to many embedded control applications. The AT89S52 provides the following standard features: 8K bytes of
Flash, 256 bytes of RAM, 32 I/O lines, Watchdog timer, two
data pointers, three 16-bit timer/counters, a six-vector
two-level interrupt architecture, a full duplex serial port,
on-chip oscillator, and clock circuitry. In addition, the
AT89S52 is designed with static logic for operation down to
zero frequency and supports two software selectable power saving
modes. 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.
