Product/Process Change Notification No: PCN1602
Change Classification: Minor
Subject: SPI port timing change for SmartFusion
®
2 and IGLOO
®
2 devices
Summary of Changes
This is to notify you about a specification change related to the setup time for the dedicated SPI ports in the
SmartFusion2 and IGLOO2 product families. The SPI ports affected are SPI_0 and SPI_1. The next revision
of the DS0128: IGLOO2 and SmartFusion2 Datasheet will reflect these changes.
Description of Changes
Setup and hold times have changed as indicated in Table 2. In addition, the maximum clock frequency has
been reduced to 20 MHz.
The following tables provide existing and new SPI specifications for your reference.
