Description of Change:
Silicon Labs recently identified firmware bug(s) affecting C8051f96x rev A devices.
This may affect device functionality when the external memory interface (EMIF) is configured in
Split Mode. The device firmware has been updated to address this issue. Devices with a date
code prior to 1221 may be susceptible if configured for Split Mode external memory interface.
Please note that this does NOT affect devices using Internal XRAM Only or External Only
memory interface configurations.
On C8051F96x devices with 128k Flash memory (C8051F960-A-GM, C8051F960-A-GQ,
C8051F961-A-GM, C8051F962-A-GM, C8051F962-A-GQ, C8051F963-A-GM), writing 0x00 to the
lock byte may prevent future Flash erases. The device firmware has been updated to address
this issue. Devices with a date code prior to 1221 may be susceptible if writing 0x00 to the
lock byte. Please note that this does NOT affect devices with on-chip Flash memory < 128k
bytes.
Customers experiencing issues with products prior to date code 1221 should contact MCU
applications at [email protected].
Reason for Change:
Firmware update.
Impact on Form, Fit, Function, Quality, Reliability:
