Instructions for Use
Power Supply:
- Connect Vcc to the power supply within the range of 2.5V to 5.5V.
- Connect GND to the ground.
Serial Interface:
- Connect the SPI pins as follows:
- CS (Chip Select): Low to enable the device.
- SCK (Serial Clock): Clock signal from the master.
- MOSI (Master Out Slave In): Data input from the master.
- MISO (Master In Slave Out): Data output to the master.
- Connect the SPI pins as follows:
Write Operation:
- Ensure CS is low.
- Send the Write Enable command (0x06).
- Send the Write command (0x02), followed by the address (0x00 to 0x57) and the data byte.
- Wait for the write cycle to complete (5ms typical, 10ms maximum).
Read Operation:
- Ensure CS is low.
- Send the Read command (0x03), followed by the address (0x00 to 0x57).
- The device will output the data byte on MISO.
Write Protect:
- To enable write protection, send the Write Disable command (0x04).
Standby Mode:
- Set CS high to put the device into standby mode, reducing current consumption.
Addressing:
- Addresses are 7-bit, ranging from 0x00 to 0x57 (0 to 87 in decimal).
Data Retention:
- Data is retained for up to 100 years under normal operating conditions.
Handling:
- Handle the device with care to avoid static damage. Use proper ESD (Electrostatic Discharge) precautions.
