Part Change Notice #10024: Datasheet changes for CFAL12832C series

Product Affected: CFAL12832C-B-B1
Date Issued: December 7, 2009
Summary: Datasheet changes for CFAL12832C series
Description: Removed all references to internal DC-DC Converter including in System Block Diagram and a DC-DC converter circuit example that cannot be used.
Wherever listed, changed references to Pin 4 from "VDD2" (VDCDC) to "NC" (No Connection). Does not apply.
Wherever listed, made a distinction between "Module Depth" maximum "2.10 mm" (includes tolerance) and nominal "2.00 mm".
In Physical Characteristics,
Changed "Aperture Rate" from "78%" to "76%".
Changed "Weight" from "1 gram (typical)" to "1.17+10% grams (typical)".
In DC Characteristics,
Changed "Logic Supply Voltage" minimum from "+2.6v" to "+2.4v".
Changed "OLED Driver Supply Voltage" from minimum "+7v" to "+7.5v" and maximum "+9.0v" to "+8.5v".
Moved "Normal Mode Power Consumption" specification from Optical Characteristics and changed typical from "32 mW" to "31 mW" and maximum from "48 mW" to "37 mW".
In Optical Characteristics, changed "Response Time" from "<1 ms" to "10μs".
For reference only. For design purposes, please use the specifications in the datasheet.
