Datasheet Modifications: I2C Bus Mode Control
The following problem is included in the explanation of the I2C bus function of this data sheet.
It will guide the correction as follows. Please read it for the explanation of this data sheet as follows.
Section: “I2C Bus Mode Control”
▪ In the explanation of the Serial Bus Interface Control Register 1
1. Delete the setting examples where the serial clock frequency exceeds 100 kHz.
2. Add the following note.

This I C bus circuit does not support the Fast mode. It supports the Standard mode only. Although
2
2
the I C bus circuit itself allows the setting of a baud rate over 100 kbps, the compliance with the I C
specification is not guaranteed in that case.
▪ In “(3) Serial clock”
1. Add the following sentence about the communication baud rate.
a. Clock source
The SCK (bits 2 to 0 in the SBICR1) is used to select a maximum transfer frequency
outputed on the SCL pin in the master mode. Set a communication baud rate that meets
the I2C bus specification, such as the shortest pulse width of tLOW, based on the equations
shown below.
Four or more machine cycles are required for both the high and low levels of the pulse
width of a clock which is input externally in both the master and slave mode.
n
tLOW = 2 /fc
n
tHIGH = 2 /fc + 12/fc
fscl = 1/(tLow + tHIGH)

Document Change Notification
The purpose of this notification is to inform customers about the launch of the Pb-free version of the
device. The introduction of a Pb-free replacement affects the datasheet. Please understand that this
notification is intended as a temporary substitute for a revision of the datasheet.
Changes to the datasheet may include the following, though not all of them may apply to this
particular device.
1. Part number
Example: TMPxxxxxxF → TMPxxxxxxFG
All references to the previous part number were left unchanged in body text. The new
part number is indicated on the prelims pages (cover page and this notification).
2. Package code and package dimensions
Example: LQFP100-P-1414-0.50C → LQFP100-P-1414-0.50F
All references to the previous package code and package dimensions were left unchanged
in body text. The new ones are indicated on the prelims pages.
3. Addition of notes on lead solderability
Now that the device is Pb-free, notes on lead solderability have been added.
4. RESTRICTIONS ON PRODUCT USE
The previous (obsolete) provision might be left unchanged on page 1 of body text. A new
replacement is included on the next page.
5. Publication date of the datasheet
The publication date at the lower right corner of the prelims pages applies to the new
device.
