Analog Devices ADuC814 MicroConverter Quick Reference Guide
The ADuC814 MicroConverter Quick Reference Guide gives developers a concise overview of the device’s architecture, including the 8052‑compatible core, programmable PLL, and on‑chip peripherals. It lists the complete instruction set, pin assignments, interrupt vectors, and special function registers needed for low‑level programming.
Key features highlighted are a 12‑bit ADC with six channels, dual 12‑bit DACs, 8 KB Flash/EE program memory, 640 B data memory, 256 × 8 b user RAM, 16 I/O lines, temperature and power‑supply monitors, and a watchdog timer. The guide also shows the functional block diagram and memory map for quick reference during hardware design and firmware development.

Questions answered in these manuals
What are the branding identifiers for the ADuC814 covered by this errata sheet?
The document applies to material branded with First Line: ADuC814, Second Line: XRU (where X is A or B), and Third Line: D20.
What happens to the Time Interval Counter if the part is in 24 hour mode and a reset occurs?
If the part is in 24 hour mode (TIMECON.6 = 1), this bit will be cleared after any reset event, causing the part to count in 255 hour mode instead.
How many wires are required for the ADuC814 to ADM1032 interface?
The interface involves only two wires, SCLK and SDATA.
