PAW3552DB : USB/PS2 Optical Mouse SoC

General Description

The PAW3552DB is a highly integrated CMOS processed

entry-level optical mouse single chip with USB and PS2

interfaces that serves as a non-mechanical motion

estimation engine for implementing a computer mouse.

The PAW3552DB also includes an internal RC oscillator to

replace an external resonator for BOM cost reduction.

The internal OTPs provides customers with flexibility of

different configurations at manufacture side.
