C8051F38x Errata

May 18th, 2012
C8051F38x Errata
Erratum #
ADC0 Maximum Supply Current Specification
External Oscillator on 32-pin packages
Affected Revision
Data Sheet Version 1.0
Revision A
Impact definition: Each erratum is marked with an impact, as defined below:
 Minor – Workaround exists.
 Major – Errata that do not conform to the data sheet or standard.
 Information – The device behavior is not ideal but acceptable. Typically, the data sheet will be
changed to match the device behavior.
1. Description: The specification in the C8051F38x data sheet (version 1.0) for the ADC0 maximum Power
Supply Current is 880 µA. The correct specification is 1 mA.
Impact: The ADC0 peripheral may require up to 120 µA more than what is stated in the data sheet.
Workaround: No workaround exists for this issue.
Resolution: Version 1.1 of the C8051F38x data sheet will include the correct value for the maximum Power
Supply Current specification.
2. Description: The external oscillator circuit is non-functional on the 32-pin packages in C, RC, and Crystal
oscillator modes. The external CMOS clock modes are functional. The affected part numbers are:
C8051F381-GQ, C8051F381-GM, C8051F383-GQ, C8051F383-GM, C8051F385-GQ, C8051F385-GM,
C8051F387-GQ, and C8051F387-GM.
Impact: The external oscillator cannot be used to generate a clock when used in the C, RC or Crystal modes
on the affected devices.
Workaround: One of the internal oscillators or an external CMOS clock may be used to provide a clock to
the device and/or its peripherals.
Resolution: Revision B of the device will allow the use of the external oscillator in C, RC and Crystal modes.
