M24M01-W 1Mb串行I2C总线的EEPROM
The M24M01-R, M24M01-HR and M24M01-W are I2C-compatible electrically erasable programmable memory (EEPROM) devices organized as 128 Kb × 8 bits.
The I2C bus is a two-wire serial interface, comprising a bidirectional data line and a clock line. The devices carry a built-in 4-bit device type identifier code (1010) in accordance with the I2C bus definition.
The M24M01-R, M24M01-HR and M24M01-W behave as slaves in the I2C protocol, with all memory operations synchronized by the serial clock. Read and Write operations are generated by the bus master and initiated by a Start condition, followed by the device select code, address bytes and data bytes. Data transfers are terminated by a Stop condition after an Ack for Write, and after a NoAck for Read.
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
