CIC751 Smart Companion ICs for Seamless Scalability of Microcontrollers
CIC751 is a 16-Channel 5 V ADC Companion IC for Automotive Embedded Control O P T I M I Z E D F O R highly demanding applications, where cost efficient 5 V analogue sensing capability is needed beyond microcontroller’s on-board resources. T A R G E T E D A T engine management control units, it features dedicated I/Os for engine position synchronous sampling and conversion. F O R S E A M L E S S extension of the microcontroller it already supports Micro Link Interface (MLI) standard, enabling a look and feel to the software almost like an internal module. An SPI interface is provided as an alternative for microcontrollers that do not support MLI yet.
