5.3 Assembly information for serial memory
1. When U13 LD2980CMxx is not assembled, use R130 instead. All mentioned memories
should be able to operate on 3.3 V. Use a voltage regulator for low voltage memories.
2. U7 supports the following series of ST memories:
M95xx - Serial SPI Bus EEPROM
M25xx - Serial SPI Bus Flash Memory
M34xx - Serial I
2
C Bus EEPROM
