AT24C16N

HGSEMI · EEPROM · DIP-8

AT24C16N from HGSEMI, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No connect. Not internally bonded; leave floating or tie to any convenient net.
2 NC unconnected No connect. Not internally bonded; leave floating or tie to any convenient net.
3 NC unconnected No connect on the AT24C16 (this pin is the E2 slave-address input on the AT24C08 variant only).
4 Vss power_in Ground reference for VCC. Connect to system ground (0 V).
5 SDA bidirectional Serial data input/output for the I2C bus. Open-drain output; requires an external pull-up resistor to VCC. May be wire-OR'ed with other open-drain devices on the bus. Input capacitance 8 pF max.
6 SCL input Serial clock input for the I2C bus (up to 400 kHz or 1 MHz depending on VCC). Data is clocked in on positive edges and clocked out on negative edges. Schmitt-trigger, filtered input; input capacitance 6 pF max.
7 WCB input Write-Control input (active-low write enable). Tie to Vss to allow normal write operations, or tie to VCC to inhibit all writes to the memory array. Internally pulled down to Vss if left floating. Input capacitance 6 pF max.
8 VCC power_in Supply voltage input, 1.7 V to 5.5 V. Read current ~0.2 mA and write current ~0.8 mA at 400 kHz (typical). Standby current 0.5-1.0 uA at 1.7 V.
