ADUC832BSZ

Product Summary

The ADUC832BSZ 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 ADUC832BSZ 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 ADUC832BSZ 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.
