Pg 4 Revision Change Notice #1505051 ____________________________________________________________________________________________________ Description of Change: Silicon Labs is pleased to announce hardware revision C of the C8051F36x devices and revision 1.1 of the corresponding datasheet for these products. For customers using Revision B the change to Revision C eliminates an issue where the CPU causes an execution failure for the “CPL C” (Complement Carry bit) instruction under a narrow set of conditions involving an instruction order dependency. The failure mode is as follows: if the Carry bit contains a 1 prior to the execution phase of the “CPL C” opcode, the Carry bit will remain a 1 after the execution phase of the opcode has completed. If the Carry bit contained a ‘0’ prior to the execution of the “CPL C” opcode, it will properly transition to a 1 when the execution phase of the opcode has completed. In the failure case, the CPL C opcode must be immediately preceded by a JB, JNB, or JBC opcode. JB, JNB, and JBC are all conditional branch instructions (JB is “Jump if bit is set”, JNB is “Jump if bit is not set”, and JBC is “Jump if bit is set and clear bit”). Because the branches are conditional, they have both a “branch taken” condition as well as a “branch not taken” condition. Both “branch taken” and “branch not taken” conditions may exhibit the error, as long as the CPL C opcode executes immediately after the branch instruction has executed. The opcode failure only exists in devices with a maximum clock frequency of 100 MHz. These include the following part numbers: C8051F360-GQ C8051F361-GQ C8051F362-GM C8051F363-GQ C8051F364-GQ C8051F365-GM The opcode dependency issue does not exist in devices that have a maximum clock rate of 50 MHz; however, since these devices share the same die a revision to the die and subsequent part number is required. These devices include the following part numbers: C8051F366-GQ C8051F367-GM C8051F368-GQ C8051F369-GM Datasheet revision 1.1 updates the orderable part number to revision C along with other minor edits. After the effective date of this PCN, Silicon Labs reserves the right to deliver Revision C for customers ordering revision B. Please refer to the product identification section. Reason for Change: C8051F36x Revision C release C8051F36x Datasheet revision 1.1 release Impact on Form, Fit, Function, Quality, Reliability: There is no impact to form, fit, quality or reliability. The following functions are impacted: - The “CPL C” (Complement Carry bit) instruction operates as expected at specified operating conditions W7206F5 Product Revision Notice Form rev C The information contained in this document is PROPRIETARY to Silicon Laboratories, Inc. and shall not be reproduced or used in part or whole without Silicon Laboratories’ written consent.
