Subject: Minimum Order Quantity, Packing and Shipping Configuration Standardization for Non-Memory ProductsChange Type: Minor Description of Change: This notification is to inform customers that Cypress will be standardizing its Full Box Quantity to a sellable quantity in the market where it will be able to round the orders in increment of this full box quantity. It may be recalled that Cypress had implemented Manufacturing Label and Packing Configuration Standardization via Product Information Notification PIN195102 in December 2019. As part of the Cypress integration into Infineon Shipping Standard, Cypress will be adjusting Minimum Order Quantity (MOQ), Order Increment (OI) to align them with new Full Box Quantity for select parts shipped in trays and tubes. These changes will be implemented immediately at all Cypress in-house and qualified subcontractor locations. Please be advised that starting July 5, 2021, all new orders must follow these new Minimum Order Quantity (MOQ)/Order Increment (OI) and Cypress will start shipping orders in new full box quantity configuration. The existing orders can remain in old MOQ/OI through end of December 2021, or change orders requiring additional lines/quantities, whichever occurs first. The transition period where customers should expect to receive either current or new shipping configurations is expected to end in December 2021. Starting January 2022, all orders must conform with the new MOQ and any existing orders not yet in new MOQ must be changed by December 15, 2021. Benefit of Change: The change is part of Cypress' continuous improvement initiative, intended to provide Cypress the means to packaging flexibility and process standardization to match industry standards and reliably meet customer delivery requirements Approximate Implementation Date: This change will be implemented on July 05, 2021. Anticipated Impact: Cypress, an Infineon Technologies Company also recommends that customers take this opportunity to review these changes against current order profile since the change will align to Infineon shipping standard as we will move our Finished Goods inventory to Infineon's Distribution Centers in Singapore and Shanghai respectively. Customers should also update their MRP or order entry systems to reflect these changes.
Addendum to PIN195102 - Manufacturing Label and Packing Configuration Standardization Description of Change: The purpose of this addendum is to correct the date from January 20, 2019 to January 20, 2020, in the "3rd paragraph in the 'Description of Change' section. This notification is to inform customers that Cypress will be standardizing its manufacturing labels and tray/tube packing configuration. It may be recalled that the Cypress entity consolidation (following the merger with Spansion Corp) was announced via Product Information Notification PIN174801 in November 2017. As the next phase of the entity consolidation process, Cypress will be adapting a new manufacturing label format for all products and revising shipping configurations for select product shipped in trays and tubes.
Description of Alert: PSoC� 1 and derivative devices began shipping in 2002, and over time they have been successfully used in a broad spectrum of applications. Unfortunately, it has recently been discovered that a skilled hacker with physical possession of a device and specific hardware and software tools can use the device in a manner not intended, and extract the data stored in Flash in circumvention of the ProtectBlock feature. Cypress is issuing this PIN to notify our customers about the recent event. PSoC� 1 and derivative devices offer external access and control of device resources through a debug/programming mode which uses the In-system Serial Programming Protocol (ISSP). If the designer chooses, it is possible to prevent external read and write access of Flash during this mode by using the ProtectBlock feature. However, the feature does not block access to SRAM memory. As a result, it is possible to circumvent the ProtectBlock feature by conducting system operations on Flash (such as CHECKSUM), capturing intermediate results in SRAM, and then indirectly reconstructing the Flash image.Note that putting the device into debug/programming mode requires presenting specific commands to the ISSP pins, clocking them in, and reading results. This typically can only be done with direct physical access to the ISSP pins and using specific external hardware and software tools. Affected PSoC� 1 and derivative device documentation will be updated to clarify the capability of ProtectBlock. Applications that do not use the ProtectBlock feature are not affected.
Planned Qualification of Spansion Manufacturing Sites for Cypress ProductsDescription of Change:In concert with the recently announced merger between Cypress Semiconductor Corporation (Cypress) and Spansion Inc. (Spansion), Cypress announces plans to qualify proprietary SONOS Technology products at Spansion Fab 25 / Test 25 in Austin, Texas and BGA/TSOP-packaged products at the Spansion assembly facility in Bangkok, Thailand. These qualifications and implementations are expected to occur throughout 2015 and 2016. Once complete, the qualifications will be announced through regular PCNs.This is an advance notification and no immediate action is needed. Refer to the attached Supplier documentation for the complete schedule of the activity, PCN issue dates and shipment start dates.
