DescriptionThe ADUC832BSZ is one member of the ADUC832 series.The ADuC832 is a complete smart transducer front end, integrating a high performance self-calibrating multichannel 12-bit ADC,dual 12-bit DACs, and programmable 8-bit MCU on a single chip.The device operates from a 32 kHz crystal with an on-chip PLL generating a high frequency clock of 16.77 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 with 12 core clock periods per machine cycle. 62 kBytes of nonvolatile Flash/EE program memory are provided on-chip. 4 kBytes of nonvolatile Flash/EE data memory, 256 bytes RAM,and 2 kBytes of extended RAM are also integrated on-chip.
Features of the ADUC832BSZ are:(1)DMA controller for high speed ADC-to-RAM capture; (2)2 12-bit (monotonic) voltage output DACs; (3)62 kbytes on-chip flash/EE program memory; (4)4 kbytes on-chip flash/EE data memory; (5)flash/EE, 100 Yr retention, 100 kcycles endurance; (6)2304 bytes on-chip data RAM; (7)8051 compatible instruction set (16 MHz max); (8)32 kHz ext crystal, on-chip programmable PLL; (9)12 interrupt sources, 2 priority levels; (10)dual data pointer; (11)extended 11-bit stack pointer.
The absolute maximum ratings of the ADUC832BSZ can be summarized as:(1)AVDD to DVDD:0.3V to +0.3 V;(2)storage temperature range:-65 to+150;(3)junction temperature:150;(4)AGND to DGND:-0.3V to +0.3V.Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.The general-purpose RAM is divided into two separate memories,namely the upper and the lower 128 bytes of RAM. The lower 128 bytes of RAM can be accessed through direct or indirect addressing. The upper 128 bytes of RAM can only be accessed through indirect addressing as it shares the same address space as the SFR space, which can only be accessed through direct addressing.
