　　The ADuC824 is a complete smart transducer front-end， integrating 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 transducer， 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-instructionset-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 256 bytes RAM are also integrated on-chip.
