Description
The AT89C1051U is a low-voltage, high-performance CMOS 8-bit microcomputer with
1K byte of Flash programmable and erasable read only memory. It has the same func-
tionality and operation as the AT89C1051 with the addition of a UART programmable
serial port. The device is manufactured using Atmel
’
s high-density nonvolatile memory
technology and is compatible with the industry-standard MCS-51 instruction set. By
combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel
AT89C1051U is a powerful microcomputer which provides a highly-flexible and cost-
effective solution to many embedded control applications.
The AT89C1051U provides the following standard features: 1K byte of Flash, 64 bytes
of RAM, 15 I/O lines, two 16-bit timer/counters, a five-vector, two-level interrupt archi-
tecture, a full duplex serial port, a precision analog comparator, on-chip oscillator and
clock circuitry. In addition, the AT89C1051U 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 hardware
reset.
