Description of Change:
Silicon Labs is pleased to announce V1.31 of the EFM8BB2 datasheet. This datasheet release
corresponds to the release of the new automotive grade EFM8BB2 devices. These new EFM8BB2
devices have received full AEC-Q100 qualification and are specified for -40 °C to +125 °C operating
temperature range. This datasheet release also corresponds to a change in one of the voltage
regulator’s calibration routines.
The calibration routines for the low dropout voltage regulator (LDO) have been updated and results in
a slightly increased (1.8 V vs. 1.85 V) typical LDO output target. This calibration change occurred due
to a small drop observed in the LDO output voltage when the device enters lower power modes during
an extended characterization study. This LDO output supplies the core and other digital logic on the
device. The new calibration method ensures this drop does not occur. No direct issues have been
observed on devices using the old calibration method, and this effort is part of the continual
improvement process.
Below is a list of changed power consumption specs from the datasheet. Note that some typical
values were also slightly increased.

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.
