Description
The AT89C1051 is a low-voltage, high-performance CMOS 8-bit microcomputer with
1K byte of Flash programmable and erasable read only memory (PEROM). 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 AT89C1051 is a power-
ful microcomputer which provides a highly-flexible and cost-effective solution to many
embedded control applications.
The AT89C1051 provides the following standard features: 1K byte of Flash, 64 bytes
of RAM, 15 I/O lines, one 16-bit timer/counter, a three vector two-level interrupt archi-
tecture, a precision analog comparator, on-chip oscillator and clock circuitry. In
addition, the AT89C1051 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.
