GENERAL DESCRIPTION

The ADuC824 is a complete smart transducer front-end, inte-
grating two high-resolution sigma delta ADCs, an 8-bit MCU,
and program/data Flash/EE Memory on a single chip. This low
power device accepts low-level signals directly from a transducer.
The two independent ADCs (Primary and Auxiliary) include a
temperature sensor and a PGA (allowing direct measurement of
low-level signals). The ADCs with on-chip digital filtering are
intended for the measurement of wide dynamic range, low-frequency
signals, such as those in weigh scale, strain-gauge, pressure trans-
ducer, or temperature measurement applications. The ADC output
data rates are programmable and the ADC output resolution will
vary with the programmed gain and output rate.
The device operates from a 32 kHz crystal with an on-chip PLL
generating a high-frequency clock of 12.58 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 therefore 8051-instruction-
set-compatible. The microcontroller core machine cycle consists
of 12 core clock periods of the selected core operating frequency.
8 Kbytes of nonvolatile Flash/EE program memory are provided
on-chip. 640 bytes of nonvolatile Flash/EE data memory and
256bytes RAM are also integrated on-chip.
The ADuC824 also incorporates additional analog functionality
with a 12-bit DAC, current sources, power supply monitor,
and a bandgap reference. On-chip digital peripherals include a
watchdog timer, time interval counter, three timers/counters,
and three serial I/O ports (SPI, UART, and I2C-compatible).
On-chip factory firmware supports in-circuit serial download and
debug modes (via UART), as well as single-pin emulation mode
via the EA pin. A functional block diagram of the ADuC824 is
shown above with a more detailed block diagram shown in
Figure 12.
The part operates from a single 3 V or 5 V supply. When operating
from 3 V supplies, the power dissipation for the part is below
10 mW. The ADuC824 is housed in a 52-lead MQFP package.
