In “Table 31. Asynchronous non-multiplexed SRAM/PSRAM/NOR read timings�? of the“STM32F103xC STM32F103xD STM32F103xE Data Sheet�? (Doc ID 14611 Rev 7) are following entries wrong?
tsu(Data_NE) | Data to FSMC_NEx high setup time | 2THCLK + 25 | ns tsu(Data_NOE) | Data to FSMC_NOEx high setup time | 2THCLK + 25 | ns Should they be? tsu(Data_NE) | Data to FSMC_NEx high setup time | 2THCLK + 2.5 | ns tsu(Data_NOE) | Data to FSMC_NOEx high setup time | 2THCLK + 2.5 | ns2011-05-17 04:37 AM

Dear User, Please find here below latest information concerning the request R10010120 The STM32 FSMC has fairly long requirement on the data set up time with respect to NOE and NE. The min. data set up times are correct in the data sheet and are (2tHCLK + 25)ns.
