T he ADuC834 also incorporates additional analog functionality  
with a 12-bit DAC, dual current sources, power supply monitor,  
and a bandgap reference. On-chip digital peripherals include two  
16-bit Σ∆ DACs/PWM, watchdog timer, real time clock (time  
interval counter), four timers/counters, and two serial I/O ports  
(UART and SPI).  
GE NE RAL D E SC RIP TIO N  
T he ADuC834 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.  
On-chip factory firmware supports in-circuit serial download (via  
UART ), as well as single-pin emulation mode via the EA pin. A  
functional block diagram of the ADuC834 is shown above with a  
more detailed block diagram shown in figure 11 (page 18).  
T he two independent ADCs (Primary and Auxiliary) include a  
temperature sensor and a PGA (allowing direct measurement of  
low-level signals). T he ADCs with on-chip digital filtering and  
programmable output data rates are intended for the measure-  
ment of wide dynamic range, low frequency signals, such as those  
in weigh scale, strain-gauge, pressure transducer, or temperature  
measurement applications.  
T he part operates from a 3V or a 5V supply. When operating from  
3V the power dissipation for the part is below 10mW. T he  
ADuC834 is housed in a 52-lead MQFP package.  
APPLICATIONS  
Intelligent Sensors (IEEE1451.2-Com patible)  
Weigh Scales  
Portable Instrum entation  
Pressure Transducers  
4–20 m A Transm itters  
T he device operates from a 32 kHz crystal with an on-chip PLL  
generating a high-frequency clock of 12.58 MHz. T his clock is,  
routed through a programmable clock divider from which the  
MCU core clock operating frequency is generated. T he micro-  
controller core is an 8052 and therefore 8051 instruction set  
compatible with 12 core clock periods per machine cycle.
