(U5) or SPI Flash W25Q64JVSSIQ (U12).

Type: Schematic Change

Reason: EOL of ComponentEPCQ SPI Flash.

Impact:None. Higher frequency could be used. Different memory sizes and frequencies are available. TEI0003-03-QFCR1A used the EPCQ memory. Therefore, the size is the same. But TEI0003-03-QFCR4A used a different memory with a bigger size. The replacement TEI0003-03-QFCR1A is only usable as long as components are available. Afterwards, only TEI0003-03-QFCR4A is usable.
