The ADUC845BSZ62-5 is a single-cycle 8-bit Microcontroller incorporates high-resolution 10-channel Σ-Δ ADCs, program and data flash/EE memory on a single chip. The device operates from a 32kHz crystal with an on-chip PLL generating a high frequency clock of 12.58MHz. This clock is routed through a programmable clock divider from which the MCU core clock operating frequency is generated. The microcontroller core is an optimized single-cycle 8052 offering up to 12.58MIPs performance while maintaining 8051 instruction set compatibility.
