This document describes the working principle and configuration methods of the timer in the ADI MicroConverter® uC018 chip.
This technical note explains the Time Interval Counter (TIC) feature found on specific Analog Devices MicroConverter parts. The TIC allows for counting longer intervals than standard timers, ranging from 1/128th of a second to 255 hours, and is clocked by an independent source to remain active during powerdown.
The document provides three specific application examples: waking the microcontroller from powerdown after a set interval, configuring the TIC to function as a real-time clock, and timing long intervals such as 96 hours. It includes C code examples for the ADuC832 to demonstrate these functions.
| Timeout Interval Range | 1/128 second to 255 hours |
|---|---|
| Supported MicroConverter Parts | ADuC814, ADuC816, ADuC824, ADuC831, ADuC832, ADuC834 |
| Clock Source | 32.768KHz watch crystal or r/c oscillator |
| Powerdown Capability | Remains active during powerdown |
Yes, the TIC can remain active during powerdown and generate an interrupt to wake up the MicroConverter.
The TIC is present on the ADuC814, ADuC816, ADuC824, ADuC831, ADuC832, and ADuC834.
