LC898123F40XC

Optical Image Stabilization (OIS) /

Auto Focus (AF) Controller & Driver

with 40kB Flash Memory

1. Overview

LC898123F40XC is a system solution integrating an ultra-low-power

32-bit DSP, Flash Memory, and analog peripherals for OIS (Optical Image

Stabilization) /AF (Auto Focus) control, H-bridge, and linear drivers.

Available in a tiny 3.22mm x 2.30mm chipscale package, this device’s

40kB Flash memory enables high level commands and user data for greater

system flexibility.
