The following changes were also made to the V1.30 and V1.31 datasheet

- The addition of table 4.11 “1.8V Internal Low Dropout Voltage Regulator” to outline its minimum,

typical, and maximum voltages.

- The addition of automotive devices in the product selection table and ordering information.

- Addition of AEC-Q100 under the key features and specifications.

- Added thermal resistance (junction to case) for the QFN20 package.

- Added a note linking to the output low voltage and output high voltage table of the port I/Os to the

performance curves.

- Added the sizes of transmit and receive FIFOs for the SMBus and I2C slave peripherals.

- Added a line in the introduction section to mention the reference manual where an individual can find

more technical information on registers and blocks.

- Added a note on the comparator reference current consumption to clarify its source.

After the issue date of this PCN, the EFM8BB2 datasheet will reflect the changes listed above and all

automotive (A) grade EFM8BB2 devices will adhere to the V1.31 datasheet. After the effective date of

this PCN all commercial (G) and industrial (I) grade EFM8BB2 devices will adhere to the specifications

in the aforementioned datasheet. For questions please contact your Silicon Labs representative.

Reason for Change:

1.

The release of the new EFM8BB2 automotive qualified devices.

2.

The release of V1.31 of the EFM8BB2 datasheet.

3.

The calibration routine for the LDO has been updated and affects power consumption

numbers in normal and idle mode.

Impact on Form, Fit, Function, Quality, Reliability:

This is considered a minor change to form, fit, function, quality, and reliability and is part of Silicon

Labs’ commitment to a continual improvement process.
