Analog Devices ADuC812 MicroConverter Errata Sheet

About this manual

This document serves as an errata sheet for the Analog Devices ADuC812 MicroConverter, detailing known bugs, anomalies, and work-arounds. It applies to all ADuC812 packaged material and is periodically updated to reflect silicon revisions and improved work-arounds.

The sheet covers specific functional issues including ADC conversion in DMA mode, UART multiprocessor communications, Port 2 internal pull-up functionality, Flash/EE memory programming at low temperatures, baud rate generation in split timer mode, power supply trip indicators, and external power-on reset operations. It provides specific work-arounds for each identified issue.

Frequently asked questions

What is the work-around for Timer2 triggered DMA conversions?

Ensure that the correct configuration sequence is used for the ADC, i.e. configure ADCCON2 then ADCCON1.

How should the DMA start address be set for Timer2 triggered conversions?

Ensure that the DMA start address is set to 000000H.

Can the device be programmed below 3V in the -40°C to 0°C range?

No, this revision of silicon will not support programming below DV DD=3V supplies in that temperature range.
