Description
The AT89C4051 is a low-voltage, high-performance CMOS 8-bit microcontroller with
4K bytes of Flash programmable and erasable read-only memory. The device is man-
ufactured using Atmel’s high-density nonvolatile memory technology and is
compatible with the industry-standard MCS-51 instruction set. By combining a versa-
tile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C4051 is a powerful
microcontroller which provides a highly-flexible and cost-effective solution to many
embedded control applications.
The AT89C4051 provides the following standard features: 4K bytes of Flash,
128 bytes of RAM, 15 I/O lines, two 16-bit timer/counters, a five-vector, two-level inter-
rupt architecture, a full duplex serial port, a precision analog comparator, on-chip
oscillator and clock circuitry. In addition, the AT89C4051 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 hardware reset.
