Description
The AT89LV55 is a low-voltage, low-power CMOS 8-bit microcontroller with 20K bytes
of Flash programmable and erasable read-only 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 pro-
gram memory to be reprogrammed. By combining a versatile 8-bit CPU with Flash on
a monolithic chip, the Atmel AT89LV55 is a powerful microcontroller which provides a
highly-flexible and cost-effective solution to many embedded control applications.
The AT89LV55 provides the following standard features: 20K bytes of Flash,
256 bytes of RAM, 32 I/O lines, 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 AT89LV55 is designed with static logic for operation down to zero fre-
quency and supports two software selectable power saving modes. The Idle Mode
stops the CPU while allowing the RAM, timer/counters, serial port, and interrupt sys-
tem to continue functioning. The Power-down Mode saves the RAM contents but
freezes the oscillator, disabling all other chip functions until the next hardware reset.
The low-voltage option saves power and operates with a 2.7-volt power supply.
