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.
