Description
The AT48801 is a low-power, high-performance CMOS 8 bit microcomputer with 8K
bytes on-board program memory. The device is compatible with the industry standard
80C51 and 80C52 instruction set and pinout. The Atmel AT48801 is a powerful micro-
computer which provides a highly flexible and cost effective solution to spread-spec-
trum applications.
The AT48801 provides the following standard features: 8K bytes of program memory,
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 AT48801 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.
