| 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. Please contact our logistics team for engineering samples sales@crystalfontz.com.
