Date
Description of Change
February 3, 2023
Updated POD links in Package Outline Drawings.
September 30, 2020 • Updated Effective Load Capacitance section; added last sentence of “Cex1...of 12.5pF”.
• Rebranded/reformatted datasheet to Renesas.
November 12, 2014
Updated device markings.
March 10, 2014
Changed tVCCF min value from 300µs to 3ms. Added associated note.
February 07, 2013
1. Changed the Vih Min value to 0.8Vcc and the Vil Max value to +0.2Vcc on page 11. This is based on new
data taken on TSMC samples (old data was from Fab 4).
2. The IBATDAT current on page 12 should change from 10nA to 120nA (Typ) and from 100nA to 300nA (Max)
per latest Characterization data from TSMC.
December 10, 2012
Updated orderable parts - added “G” to 16-pin SOIC parts with SRI/SRI8. New part numbers for 16-pin SOIC
will read as SRGI and SRGI8.
September 20, 2012 1. Moved all from Fab4 to TSMC. QA requested change in the marking of only the 16-pin SOIC device with
internal crystal to add “A” due to the fact that TSMC uses a different crystal than Fab4. Notification of a change
in orderables was initiated with PCN A1208-06.
2. Updated 16-pin SOIC marking diagram and ordering information to include “A”.
October 17, 2011
Added separate item for tVCCF in “Power-up/Down Conditions” table for 1338-31; 300µs min.
September 22, 2011 Changed “VCC Fall Time; VPF(MAX) to VPF(MIN)” spec from 300µs Min. to 1ms Min. (Table 2,
“Power-Up/Down Characteristics).
April 13, 2011
March 29, 2010
Updated Supply Current specifications.
Added “Timeout” paragraph on page 8.

Added “Handling, PCB Layout, and Assembly” section.
Updated Typical Operating Characteristics graphs; added marking diagrams.
Updated graphs in “Typical Operating Characteristics; added “Typical Operating Circuit” diagram.
Updated Block Diagram; Typical Operating Characteristics charts.
The part number for 16pin RoHS complaint part has now changed from 1338C-31SOGI to 1338C-31SRI and
the 1338C-18SOGI changed to 1338C-18SRI.
