ADUC843BSZ62-5

Product Summary

The ADUC843BSZ62-5 is a complete smart transducer front end. It integrates a high performance selfcalibrating multichannel ADC, a dual DAC, and an optimized single-cycle 20 MHz 8-bit MCU (8051 instruction set compatible) on a single chip. The ADUC843BSZ62-5 is an optimized 8052 core offering up to 20 MIPS peak performance. Three different memory options are available offering up to 62 kBytes of nonvolatile Flash/EE program memory. Four kBytes of nonvolatile Flash/EE data memory, 256 bytes RAM, and 2 kBytes of extended RAM are also integrated on-chip. The applications of the ADUC843BSZ62-5 include Optical networking-laser power control, Base station systems, Precision instrumentation, smart sensors, Transient capture systems and DAS and communications systems.
