Description
The AT89LS51 is a low-voltage, high-performance CMOS 8-bit microcontroller with 4K
bytes of in-system programmable Flash memory. The device is manufactured using
Atmel’s high-density nonvolatile memory technology and is compatible with the indus-
try-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 pro-
grammer. By combining a versatile 8-bit CPU with in-system programmable Flash on a
monolithic chip, the Atmel AT89LS51 is a powerful microcontroller which provides a
highly-flexible and cost-effective solution to many embedded control applications.
The AT89LS51 provides the following standard features: 4K bytes of Flash, 128 bytes
of RAM, 32 I/O lines, Watchdog timer, two data pointers, two 16-bit timer/counters, a
five-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator,
and clock circuitry. In addition, the AT89LS51 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 con-
tents but freezes the oscillator, disabling all other chip functions until the next external
interrupt or hardware reset.
