ADUC842 Datasheet PDF

●The ADUC842BSZ62-5 is a single-cycle 20MHz 8-bit Microcontroller incorporates a high-performance self calibrating multichannel ADC and dual DAC on a single chip. The ADuC842 is identical with the exception of the clock oscillator circuit. The ADuC842 uses a 32kHz crystal with an on-chip PLL generating a programmable core clock up to 16.78MHz. The microcontroller is an optimized 8052 core offering up to 20MIPS peak performance. Three different memory options are available offering up to 62kB of nonvolatile flash/EE program memory. 4kB of nonvolatile Flash/EE data memory, 256byte RAM and 2kB of extended RAM are also integrated on-chip.
