Description

The AT8xC5112 is a high performance ROM/OTP version of the 80C51 8-bit

microcontroller.

The AT8xC5112 retains all the features of the standard 80C51 with 8 Kbytes

ROM/OTP program memory, 256 bytes of internal RAM, a 8-source, 4-level interrupt

system, an on-chip oscillator and two timer/counters.

The AT8xC5112 is dedicated for analog interfacing applications. For this, it has a 10-

bit, 8 channels A/D converter and a five channels Programmable Counter Array.

In addition, the AT8xC5112 has a Hardware Watchdog Timer, a versatile serial chan-

nel that facilitates multiprocessor communication (EUART) with an independent baud

rate generator, a SPI serial bus controller and a X2 speed improvement mechanism.

The X2 feature allows to keep the same CPU power at a divided by two oscillator

frequency.

The fully static design of the AT8xC5112 allows to reduce system power consumption

by bringing the clock frequency down to any value, even DC, without loss of data.
