M34D64 64K串行特殊应用EEPROM
The M34D64-W are I²C-compatible electrically erasable programmable memory (EEPROM) devices organized as 8192 x 8 bits.
These devices are compatible with the I²C memory protocol. This is a two-wire serial interface that uses a bidirectional databus and serial clock. The devices carry a built-in 4-bit Device Type Identifier code (1010) in accordance with the I²C bus inition.
The device behaves as a slave in the I²C protocol, with all memory operations synchronized by the serial clock. Read and Write operations are initiated by a Start condition, generated by the bus master. The Start condition is followed by a Device Select Code and Read/Write bit (RW) (as described in Table 2.: Device select code), terminated by an acknowledge bit.
When writing data to the memory, the device inserts an acknowledge bit during the 9th bit time, following the bus master’s 8-bit transmission. When data is read by the bus master, the bus master acknowledges the receipt of the data byte in the same way. Data transfers are terminated by a Stop condition after an Ack for Write, and after a NoAck for Read.
