M24C02-DRMF3TG/K Pinout

Package: 8-WFDFN (DFN8 - 2 x 3 mm)

Notes

• E0, E1, E2 pins: Chip enable address inputs. Must be tied to VCC or VSS; when left floating, read as low (0). These three pins set the least significant 3 bits (b3, b2, b1) of the 7-bit device select code, allowing up to 8 devices on a single I²C bus.
• SDA (Serial Data): Open-drain output; requires external pull-up resistor to VCC. Used for bidirectional data transfer on the I²C bus.
• SCL (Serial Clock): Input only; strobes data on SDA. Requires external pull-up resistor to VCC.
• WC (Write Control): When driven high, write operations are disabled for the entire memory array. When driven low or left floating, write operations are enabled.
• VCC/VSS: Recommended decoupling capacitor (10 nF to 100 nF) should be placed close to these pins.
• Operating voltage range: 1.7 V to 5.5 V
• Operating temperature range: −40 °C to 125 °C
• Pin numbers extracted from the 8-pin DFN package diagram provided.

In order to meet environmental requirements, ST offers these devices in different grades of ECOPACK packages, depending on their level of environmental compliance. ECOPACK specifications, grade definitions and product status are available at: www.st.com. ECOPACK is an ST trademark.
