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.
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.
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).
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.
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.
