64Kbit I²C EEPROM in 8-TSSOP — active production, industrial temp range
The M24C64-RDW6TP: The 450 ns access time governs the read-cycle timing — the master's SCL low-to-high transition must respect this window, but the I²C protocol's ACK/NACK handshake normally absorbs it. Write cycles, whether page or word, complete in 5 ms typical per the datasheet; the master should poll for ACK or use the write-cycle-in-progress status bit before issuing the next command.
Supply voltage and temperature grade — mixed-voltage and industrial deployment
The wide range eliminates the need for a dedicated regulator when the board already has one of these voltages, but the I²C bus pull-up resistors must be sized for the highest Vcc on the bus to ensure proper logic levels.
