20x4 Parallel Character OLED

Part Number: CFAL2004A-Y

Consider using this 4x20 character yellow OLED to possibly lower the power requirements for designs using a STN character display.

  • Also available in other color variations  (minimum order may be required)
  • 8-bit or 4-bit parallel interface
  • The WS0010 controller interface is very similar to industry standard Hitachi HD44780.
  • Operating temperature range from -40°C to 80°.

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.

Part Change Notice #11032: Bezel Change

Product Affected: CFAL2004A-Y
Date Issued: January 22, 2019
Summary: Bezel Change
Description: The Bezel will be modified to add 2 holes on each of the right and left sides of the Bezel.
Reason: This will improve the Bezel alignment and installation during the assembly process.
Impact: This will not affect the operation of the display.
Recommendation: None
Availability: The displays with the revised Bezels will be available after current stock is depleted.
Price Change: None
