Bulletin Details
Description:
Silicon Labs is pleased to announce that version 1.2 of the C8051F55x/56x/57x data sheet is now
available. The revision includes:
Power-On Reset may fail for devices shipped prior to date code 1124
- Added a note regarding an issue with /RST low time on some older devices to “Power-On Reset” on
page 140.
This issue was previously documented in the errata and has now been moved to the data sheet. It has
been removed from the errata.
Note: For devices with a date code before year 2011, work week 24 (1124), if the /RST pin is held low
for more than 1 second while power is applied to the device, and then /RST is released, a percentage
of devices may lock up and fail to execute code. Toggling the /RST pin does not clear the condition.
The condition is cleared by cycling power. Most devices that are affected will show the lock up
behavior only within a narrow range of temperatures (a 5 to 10 degrees C window). Parts with a date
code of year 2011, work week 24 (1124) or later do not have any restrictions on /RST low time. The
date code of a device is a four-digit number on the bottom-most line of each device with the format
YYWW, where YY is the two-digit calendar year and WW is the two digit work week.
Use VDD Monitor low threshold setting during normal operation
– Added the note regarding the voltage regulator and VDD monitor in the high setting from “Power-Fail
Reset/VDD Monitor” on page 140 to “Voltage Regulator (REG0)” on page 80 and “VDD Maintenance and
the VDD monitor” on page 130.
This note already existed in the data sheet in the Reset Sources chapter, and it’s been added to
additional locations to make it more prominent.
Note: The output of the internal voltage regulator is calibrated by the MCU immediately after any
reset event. The output of the un-calibrated internal regulator could be below the high threshold
setting of the VDD Monitor. If this is the case and the VDD Monitor is set to the high threshold setting
and if the MCU receives a non-power on reset (POR), the MCU will remain in reset until a POR occurs
(i.e., VDD Monitor will keep the device in reset). A POR will force the VDD Monitor to the low threshold
setting which is guaranteed to be below the un-calibrated output of the internal regulator. The device
will then exit reset and resume normal operation. It is for this reason Silicon Labs strongly
recommends that the VDD Monitor is always left in the low threshold setting (i.e. default value upon
POR).
