Product Description

The ADUC834BSZ is a 8-bit Microcontroller incorporates two high-resolution Σ-Δ ADCs and program/data flash/EE memory on a single chip. The two independent ADCs (primary and auxiliary) include a temperature sensor and a PGA. 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 8052 and therefore 8051 instruction set compatible with 12 core clock periods per machine cycle. 62kB of nonvolatile Flash/EE program memory, 4kB of nonvolatile Flash/EE data memory and 2304byte of data RAM are provided on-chip. The program memory can be configured as data memory to give up to 60kB of NV data memory in data logging applications.
