Product description

The iC-PZ is a complete lensless optical reflective absolute encoder IC. With its integrated blue LED and interpolator, the iC-PZ provides a high-resolution single-chip absolute linear or rotary encoder solution. Independently configurable BiSS/SSI, ABZ, UVW, SPI, and analog Sin/Cos outputs may be used singly or in combination to provide a highly flexible system. FlexCount® and FlexCode® allow arbitrary ABZ resolution and arbitrary code disc diameter.

Features

• Reflective, compact, high-resolution, absolute encoder iC
• iC-PZ0974 and iC-PZ2656 for reflective code discs up to ø45 mm
• iC-PZ205 for reflective code discs > ø45 mm and linear scales (max. 6.71m)
• Miniature oQFN32 5×5 package
• Monolithic HD Phased Array with excellent signal matching
• System-on-chip design with embedded blue LED for excellent reliability, EncoderBlue®
• FlexCount® interpolation for arbitrary ABZ resolutions
• FlexCode® circuitry for arbitrary code disc diameters
• UVW commutation signals with 1 to 32 CPR, for motors of up to 32 pole pairs
• LED power control for constant illumination (sine square or sum control)
• Absolute singleturn resolution of 22 bits (ø26 mm) via built-in interpolation
• On-chip automatic signal adjustment
• Calibration and configuration storage via external I²C EEPROM
• Digital BiSS, SSI, and SPI interfaces with CMOS I/O
• Temperature detection and monitoring
• 2.5, 3.3, and 5.0 V compatible I/O ports
• Configurable analog outputs
• Absolute data interface for connection of external multiturn sensors
