SPCP6651B
Full Speed USB Optical Gaming Mouse SoC
High-performance single-chip optical gaming mouse solution integrating optical sensor and USB MCU, powered by SunplusIT proprietary optical navigation technology.
66 IPS Tracking
Accurate motion capture up to 66 inches per second for gaming-grade responsiveness.
Single-Chip Integration
Optical sensor and USB MCU in one package, simplifying BOM and assembly flow.
72 MHz Performance
Up to 72 MHz CPU speed with built-in ±0.25% oscillator for stable high-speed USB operation.
General Description
The SPCP6651B provides a complete and compact optical mouse solution with no moving parts and no precision optical alignment requirement, reducing external components and improving production efficiency.
It integrates a USB MCU and fully supports USB Spec V2.0 and USB HID Spec V1.1 without an external controller. The symmetrical PDIP 12-pin optical package enables flexible industrial design and easier layout for high-volume mouse projects.
The SoC supports standard 3-button input (R/M/L), X-Y motion, mechanical wheel encoding (1:2), and optional 4th/5th button expansion with multi-speed CPI switching through dedicated buttons.
