GENERAL DESCRIPTION
The ADuC834 is a complete smart transducer front end,
integrating two high resolution -
ADCs, an 8-bit MCU, and
program/data Flash/EE memory on a single chip.
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 and
programmable output data rates are intended for the measurement
of wide dynamic range, low frequency signals, such as those in
weigh scale, strain-gage, pressure transducer, or temperature
measurement applications.
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
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
with 12 core clock periods per machine cycle.
62 Kbytes of nonvolatile Flash/EE program memory, 4 Kbytes of
nonvolatile Flash/EE data memory, and 2304 bytes of data RAM
are provided on-chip. The program memory can be configured
as data memory to give up to 60 Kbytes of NV data memory in
data logging applications.
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. The ADuC834 is supported by a QuickStart
development system featuring low cost software and hardware
development tools.
