Si7006/7/13/15/20/21/22/23 Transition from A10 to A20
●Description of Change:
Silicon Labs is pleased to announce the successful qualification and availability of Si7006/7/13/15/20/21/22/23-A20 products, which will replace the existing A10 versions. All of the A20 products contain higher final test coverage. In addition, a conditionwhere the Si7006/13/20/21 I2C devices do not fully enter standby mode after a user register write has been fixed.
After the effective date of this PCN, Silicon Labs reserves the right to deliver Si7006/7/13/15/20/21/22/23-A20for customers orderingSi7006/7/13/15/20/21/22/23-A10.
●Reason for Change:
The higher final test coverage reduces potential defect rates, and improves lead times resulting from better manufacturing yields. For Si7006/13/20/21 I2C devices, the current consumption following a user register write has been reduced.
●Impact on Form, Fit, Function, Quality, Reliability:
Compared to the previous A10 versions, the Si7006/7/13/15/20/21/22/23-A20 devices are silicon metal revisions that are fully pin-compatible and software-compatible with the previous A10 versions. For Si7006/13/20/21 devices, the supply current after a userregister write has been reduced from 20μA(typ) to the normal standby current of 0.06μA(typ). The higher test coverage reduces potential defect rates and improves manufacturing yields. There is no impact to reliability.
