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. The ADuC832 also incorporates additional analog functionality with two 12-bit DACs, power supply monitor, and a band gap reference. On-chip digital peripherals include two 16-bit DACs, dual output 16-bit PWM, watchdog timer, time interval counter, three timers/counters, Timer 3 for baud rate generation, and serial I/O ports (SPI, I2C, and UART) On-chip factory firmware supports in-circuit serial download and debug modes (via UART) as well as single-pin emulation mode via the EA pin. The ADuC832 is supported by QuickStartTM and QuickStart Plus development systems featuring low cost software and hardware development tools. A functional block diagram of the ADuC832 is shown above with a more detailed block diagram shown in Figure 1.
