Part Change Notice #11101: Reset Pin Change

Products Affected: CFAL2004A-Y, CFAL2002A-Y, CFAL1602L0-Y, CFAL1202A-Y, CFAL5016A-Y, CFAL0802A-Y, CFAL1602C-B, CFAL1602C-W, CFAL1602C-Y
Date Issued: August 17, 2021
Summary: Reset Pin Change
Description: RST and CST, the components in the RC filter for the reset pin, are being modified. RST will be 33kOhms and CST will be 1uF.
Reason: Some reset circuits have shown not to be strong enough to drive the reset pin within the specified timing. If the reset circuit is not strong enough, the controller will not properly reset which causes abnormal behavior.

Part Change Notice #11077: Small Layout Change

Products Affected: CFAL2004A-Y, CFAL2002A-Y, CFAL1602L0-Y, CFAL1202A-Y, CFAL5016A-Y, CFAL0802A-Y, CFAL1602C-W, CFAL1602C-Y, CFAL1602C-YT, CFAL1602C-PW, CFAL1602C-PY, CFAL5016A-PY
Date Issued: February 10, 2021
Summary: Small Layout Change
Description: Changing manufacturing locations of the wafers used in the controller chip. The layout has to be slightly modified to accommodate the practices at the new facility. The functionality will remain the same.
Reason: Changing manufacturing locations due to the wafer process no longer being supported by the original facility.
