The ADUC814ARUZ is a fully integrated 247kSPS 8-bit Programmable Microcontroller incorporates a high performance multichannel ADC and program/data flash/EE memory on a single chip. This low power device operates from a 32kHz crystal with an on-chip PLL generating a high frequency clock of 16.78MHz. 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 is compatible with an 8051 instruction. 8kB of nonvolatile Flash/EE program memory are provided on-chip. 640byte of nonvolatile Flash/EE data memory and 256byte RAM are also integrated on-chip. The ADuC814 also incorporates additional analog functionality with dual 12-bit DACs, a power supply monitor and a band gap reference. On-chip digital peripherals include a watchdog timer, time interval counter, three timer/counters and two serial I/O ports (SPI and UART).
