LC898123F40XC: Optical Image Stabilization (OIS) / Auto Focus (AF) Controller & Driver with 40 KB Flash Memory
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 3.22 mm x 2.30 mm chipscale package, this device’s 40 KB Flash memory enables high level commands and user data for greater system flexibility.
Features- Flash Memory40 kByte Flash memory to store data and DSP program
- Hall AD converter14-bitInput 4 ch
- Onchip 32-bit DSPBuilt-in software digital servo filterBuilt-in software Gyro filter
- DA converter for Hall Offset setting : 3-bit / 3 ch
- DA converter for Hall Bias : 8-bit / Output 3 ch
- Built-in Serial I/F circuit(2-wire Bus with clock stretch function) [1 MHz]
- Built-in Hall Amp(Gain of Op-amp : x5, x10, x13, x20, x40, x60)
