GENERAL DESCRIPTION  
The ADuC814 is a fully integrated 247 kSPS, 12-bit data acquisi-  
tion system incorporating a high performance multichannel  
ADC, an 8-bit MCU, and program/data Flash/EE memory on a  
single chip.  
This low power device operates from a 32 kHz crystal with an  
on-chip PLL generating a high frequency clock of 16.78 MHz.  
This clock is, in turn, routed through a programmable clock  
divider from which the MCU core clock operating frequency is  
generated.  
11 interrupt sources, 2 priority levels  
Power  
Specified for 3 V and 5 V operation  
Normal: 3 mA @ 3 V (core CLK = 2.1 MHz)  
Power-down: 15 µA (32 kHz oscillator running)  
On-chip peripherals  
Power-on reset circuit (no need for external POR device)  
Temperature monitor ( 1.5ꢀC accuracy)  
Precision voltage reference  
The microcontroller core is an 8052 and is compatible with an  
8051 instruction. 8 kBytes of nonvolatile Flash/EE program  
memory are provided on-chip. 640 bytes of nonvolatile Flash/EE  
data memory and 256 bytes RAM are also integrated on-chip.  
Time interval counter (wake-up/RTC timer)  
UART serial I/O  
The ADuC814 also incorporates additional analog functionality  
with dual 12-bit DACs, a power supply monitor, and a band gap  
reference. On-chip digital peripherals include a watchdog timer,  
time interval counter, three timer/counters, and two serial I/O  
ports (SPI and UART).  
SPI®/I2C® compatible serial I/O  
Watchdog timer (WDT), power supply monitor (PSM)  
Package and temperature range  
28-lead TSSOP 4.4 mm × 9.7 mm package  
Fully specified for −40ꢀC to +125ꢀC operation  
On-chip factory firmware supports in-circuit serial download  
and debug modes (via UART), as well as single-pin emulation  
mode via the DLOAD pin. The ADuC814 is supported by a  
QuickStart™ Development System.  
APPLICATIONS  
Optical networking—laser power control  
Base station systems—power amplifier bias control  
Precision instruments, smart sensors  
The part operates from a single 3 V or 5 V supply over the  
extended temperature range −40°C to +125°C. When operating  
from 3 V supplies, the power dissipation for the part is below  
10 mW. The ADuC814 is housed in a 28-lead TSSOP package.  
Battery-powered systems, precision system monitors
