Part Change Notice #10405: Reactivation of the CFA635 family of modules with 1v2 hardware and supporting firmware.

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: Reactivation of the CFA635 family of modules with 1v2 hardware and supporting firmware.
Last revision: 1v1
Description: The CFA635 family of modules is being reactivated with a new LCD controller chip, the Rockworks RW1067. The changes to the CFA635 1v2 hardware are as follows:

  1. LCD controller changing from Samsung S6A0073 to Rockworks RW1067

  2. Supporting driving circuitry between the LCD controller and the LCD glass has been updated to support the Rockworks RW1067

  3. The PCB layout has been updated to support the Rockworks RW1067

  4. Firmware updates to support the Rockworks RW1067 and functional improvements See PCN #10406


The only changes to the CFA635 family are to support the Rockworks RW1067 controller. There are no other physical changes to the CFA635.
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.
