The M24M01-D offers an additional page, named the Identification Page (256 bytes). The
Identification Page can be used to store sensitive application parameters which can be
(later) permanently locked in Read-only mode.

Features
• Compatible with all I2C bus modes:
– 1 MHz
– 400 kHz
– 100 kHz
• Memory array:
– 1 Mbit (128 Kbytes) of EEPROM
– Page size: 256 bytes
– Additional Write lockable page
(M24M01-D order codes)
• Single supply voltage and high speed:
– 1 MHz clock from 1.7 V to 5.5 V
• Write:
– Byte Write within 5 ms
– Page Write within 5 ms
• Operating temperature range:
– from
-40 °C up to +85 °C
• Random and sequential Read modes
• Write protect of the whole memory array
• Enhanced ESD/Latch-Up protection
• More than 4 million Write cycles
• More than 200-years data retention Packages
• SO8 ECOPACK2®
• TSSOP8 ECOPACK2®
• WLCSP ECOPACK2®
• Unsawn wafer (each die is tested)

2.1 Serial Clock (SCL)
The signal applied on the SCL input is used to strobe the data available on SDA(in) and to output the data on SDA(out).
2.2 Serial Data (SDA)
SDA is an input/output used to transfer data in or data out of the device. SDA(out) is an open drain output that may be wire-OR’ed with other open drain or open collector signals on the bus. A pull-up resistor must be connected (Figure 12 indicates how to calculate the value of the pull-up resistor).
2.3 Chip Enable (E1, E2)
These input signals are used to set the value that is to be looked for on the two bits (b3, b2) of the 7-bit device select code. These inputs must be tied to VCC or VSS, to establish the device select code as shown in Figure 4. When not connected (left floating), These inputs are read as low (0,0).
2.4 Write Control (WC)
This input signal is useful for protecting the entire contents of the memory from inadvertent write operations. Write operations are disabled to the entire memory array when Write Control (WC) is driven high. Write operations are enabled when Write Control (WC) is either driven low or left floating.
When Write Control (WC) is driven high, device select and address bytes are acknowledged, Data bytes are not acknowledged.
