The ADuC842 is a complete smart transducer front-end, integrating a high-performance self calibrating multichannel ADC, dual DAC and an optimized single cycle 16MHz 8-bit MCU(8051 instruction set compatible) on a single chip. The device operates from a 32 kHz crystal with an on-chip PLL generating a high-frequency clock of 16.77MHz. This clock is, in turn, routed through a programmable clock divider from which the MCU core clock operating frequency is generated. The microcontroller is an optimized 8052 core offering up to 16 MIPS peak performance. 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 ADuC842 also incorporates additional analog functionality with two 12-bit DACs, power supply monitor, and a bandgap reference. On-chip digital peripherals include two 16-bit DACs, dual output 16-bit PWM, watchdog timer, time interval counter, three timers/counters, and three serial I/O ports (SPI, I2C and UART).
