Part Change Notice #10853: CFA635 series Firmware revision 2.1.
Part Change Notice #10852: CFA635 series Hardware revision 1.5
Part Change Notice #10406: Supporting firmware for the reactivation of the CFA635 family of modules.
| Products Affected: | CFA635-YYE-KS, CFA635-TMF-KS, CFA635-TFE-KS, CFA635-TMF-KL, CFA635-TFE-KL, CFA635-TFE-KU, CFA635-YYE-KL, XES635BK-TFE-KU, XES635BK-TMF-KU, XES635BK-YYE-KU, CFA635-TMF-KU, CFA635-YYE-KU |
| Date Issued: | March 20, 2012 |
| Summary: | Supporting firmware for the reactivation of the CFA635 family of modules. |
| Last revision: | 1v6 |
| Description: | The CFA635 family of modules is being reactivated with a new LCD controller chip, the Rockworks RW1067. The majority of the changes to the firmware have been in support of the RW1067 LCD controller and are transparent to the user interface. The changes to the CFA635 2v0 firmware: For hardware changes related to this firmware update, please see PCN #10405 Updates Command 1 (0x01): Get Hardware & Firmware Version Modules with the serial interface, -KL and -KS suffix, will report: CFA635:h1v2,s2v0 Modules with the USB interface, -KU suffix, will report: CFA635:h1v2, u2v0 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: | When the CFA635 family was scheduled for End of Life (see PCN #10365) there was no replacement available for the Samsung S6A0073 LCD controller. The CFA735 family was designed as replacement for the CFA635, allowing a path for improved performance, graphics, and the ability for end users to write their own firmware to take advantage of the capabilities of the enhanced hardware. After the development of the CFA735 family, the RW1067 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 CFA635 family of modules. The CFA635 can continue to be used in current and future designs. |
| Recommendation: | Continue to order and build with the CFA635 as required by production schedules. Transition to the CFA635 1v2 hardware and supporting firmware should be a seamless process. Engineering samples for qualification for the revised CFA635 are scheduled to be available Q3 of 2012. |
| Availability: | Q2 2012 Review / Update customer Defined Part custom firmware Q3 2012 New hardware and supporting firmware available for engineering samples Estimated - Begin transition to 1v2 hardware as 1v1 hardware inventory is depleted NOTE: We will not ship production orders of 1v2 hardware until the 1v1 inventory is depleted Q4 2012 Estimated - CFA635 1v1 hardware to be exhausted, transition to CFA635 1v2 hardware complete |
| Price Change: | No scheduled price change at this time. |
