End-Of-Life #11130: End-Of-Life Notification

Products Affected: CFAF240400C0-030SC-A1-1, CFAF240400C0-030SC-A1-2, CFAF240400E0-030TN-A1-2, CFAF240400E0-030TN-A1-1
Date Issued: June 9, 2022
Summary: End-Of-Life Notification
Description: Some modifications are being made to the PCB design to improve reliability and manufacturability. The board cutout for the capacitive touch screen is being moved and the reset line to the EVE chip is being routed to the reset pin for the helper processor onboard.

The parts are being replaced as follows:
CFAF240400C0-030SC-A1-1 -> EOL and replace with CFA240400E1-030TC
CFAF240400C0-030SC-A1-2 -> EOL and replace with CFA240400E1-030TC-KIT
CFAF240400E0-030TN-A1-1 -> EOL and replace with CFA240400E1-030TN
CFAF240400E0-030TN-A1-2 -> EOL and replace with CFA240400E1-030TN-KIT
Reason: The current PCB design requires the capacitive touch screen FPC tail to be stretched and needs to be given more slack.

The reset line is not brought out to the helper processor on the current PCB revision so a reset toggle does not truly reset the whole system.

Current PCB revision: 10097 h0v3

Part Change Notice #11080: Firmware Change

Products Affected: CFAF240400C0-030SC-A1-1, CFAF240400C0-030SC-A1-2, CFAF240400E0-030TN-A1-2, CFAF240400E0-030TN-A1-1
Date Issued: March 15, 2021
Summary: Firmware Change
Description: The firmware is being updated to better manage the power down sequence.
Reason: If the power down was very short, it could cause the microcontroller to go into a weird state resulting in abnormal display operation.
Availability: Will be available in the next couple of weeks. We will release a notice when the cutover occurs.
