Part Change Notice #10428: CFA631 family Firmware version 3v1

Products Affected: CFA631-RMF-KU, CFA631-TMF-KU
Date Issued: August 3, 2012
Summary: CFA631 family Firmware version 3v1
Last revision: v2.1
Description: The CFA631 family of modules is being revised to support a new LCD controller chip, the Rockworks RW1067. The changes to the CFA631 3v1 firmware are as follows.

For hardware changes, please see PCN #10427.

Updates:
Command 1 (0x01): Get Hardware & Firmware Version
Modules with the USB interface, -KU suffix, will report: CFA631:h2v4,u3v1

Command 12 (0x0C): Set LCD Cursor Style
Option 4 = inverting, blinking block is no longer supported. This option will result in a blinking underscore.

Command 22 (0x16): Send Command Directly to the LCD Controller
Any command sent specifically to the Samsung S6A0073 will need to be reviewed / modified for the commands / registers of the Rockworks RW1067. Please contact the Crystalfontz Engineering Support Team at support@crystalfontz.com for the RW1067 datasheet.

Enhancements:
Command 28 (0x1C): Set ATX Power Switch Functionality
Added auto polarity switch.
Improved pulse length functionality.
Added feature to hold until system off during power down.

Fixes:
Updates to timings and sequence of Serial interface power up to prevent possible corruption of data displayed
Reason: The Samsung S6A0073 LCD controller used was scheduled as End of Life. This EOL affected a number of intelligent modules from Crystalfontz America, Inc. The replacement RW1067 LCD controller was developed as a replacement for the Samsung S6A0073 LCD controller for Crystalfontz America, Inc by Rockworks (China).
Impact: This announcement impacts all variants, interfaces, and part numbers that currently use the CFA631 family of modules. The CFA631 can continue to be used in current and future designs.
Recommendation: Continue to order and build with the CFA631 as required by production schedules. Transition to the CFA631 h2v4 hardware and supporting firmware should be a seamless process. Engineering samples for qualification for the revised CFA631 are scheduled to be available Q3 of 2012.
