The ADuC836 is a complete smart transducer front end, integratingtwo high resolution Σ-Δ ADCs, an 8-bit MCU, and program/dataFlash/EE memory on a single chip.The two independent ADCs (primary and auxiliary) include atemperature sensor and a PGA (allowing direct measurementof low level signals). The ADCs with on-chip digital filtering andprogrammable output data rates are intended for the measurementof wide dynamic range, low frequency signals, such as thosein weigh scale, strain gage, pressure transducer, or temperaturemeasurement applications.The device operates from a 32 kHz crystal with an on-chip PLLgenerating a high frequency clock of 12.58 MHz. This clock isrouted through a programmable clock divider from which the MCUcore clock operating frequency is generated. The microcontrollercore is an 8052 and therefore 8051 instruction set compatiblewith 12 core clock periods per machine cycle.62 Kbytes of nonvolatile Flash/EE program memory, 4 Kbytes ofnonvolatile Flash/EE data memory, and 2304 bytes of data RAMare provided on-chip. The program memory can be configured asdata memory to give up to 60 Kbytes of NV data memory in datalogging applications.On-chip factory firmware supports in-circuit serial download anddebug modes (via UART), as well as single-pin emulation modevia the EA pin. The ADuC836 is supported by a QuickStart™development system featuring low cost software and hardware development tools.Applications Intelligent sensors Weigh scales Portable instrumentation, battery-powered systems 4–20 mA transmitters Data logging Precision system monitoring

The ADuC845, ADuC847, and ADuC848 are single-cycle,12.58 MIPs, 8052 core upgrades to the ADuC834 andADuC836. They include additional analog inputs forapplications requiring more ADC channels.The ADuC845, ADuC847, and ADuC848 are complete smarttransducer front ends. The family integrates high resolutionΣ-Δ ADCs with flexible, up to 10-channel, input multiplexing, afast 8-bit MCU, and program and data Flash/EE memory on asingle chip.The ADuC845 includes two (primary and auxiliary) 24-bit Σ-ΔADCs with internal buffering and PGA on the primary ADC.The ADuC847 includes the same primary ADC as the ADuC845(auxiliary ADC removed). The ADuC848 is a 16-bit ADCversion of the ADuC847.The ADCs incorporate flexible input multiplexing, a temperaturesensor (ADuC845 only), and a PGA (primary ADC only)allowing direct measurement of low-level signals. The ADCsinclude on-chip digital filtering and programmable output datarates that are intended for measuring wide dynamic range andlow frequency signals, such as those in weigh scale, strain gage,pressure transducer, or temperature measurement applications.The devices operate from a 32 kHz crystal with an on-chip PLLgenerating a high frequency clock of 12.58 MHz. This clock isrouted through a programmable clock divider from which theMCU core clock operating frequency is generated. The microcontrollercore is an optimized single-cycle 8052 offering up to12.58 MIPs performance while maintaining 8051 instruction setcompatibility.The available nonvolatile Flash/EE program memory optionsare 62 kbytes, 32 kbytes, and 8 kbytes. 4 kbytes of nonvolatileFlash/EE data memory and 2304 bytes of data RAM are alsoprovided on-chip.
