AT24CS16-XHM-T from Microchip Tech, in a TSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No Connect pin per Table 2-1 (TSSOP column); the datasheet defines no function for this pin. |
| 2 | NC | unconnected | No Connect pin per Table 2-1 (TSSOP column); the datasheet defines no function for this pin. |
| 3 | NC | unconnected | No Connect pin per Table 2-1 (TSSOP column); the datasheet defines no function for this pin. |
| 4 | GND | power_in | Ground reference for the power supply, which should be connected to the system ground. |
| 5 | SDA | bidirectional | Open-drain bidirectional serial data pin that must be pulled high with an external pull-up resistor not exceeding 10 kΩ and may be wire-ORed with other open-drain or open-collector devices. |
| 6 | SCL | input | Serial clock input: SDA data is latched on the rising edge of SCL and output data is clocked out on the falling edge, and SCL must be forced high when the bus is idle or pulled high with a pull-up resistor. |
| 7 | WP | input | Write-protect input: connecting it to GND allows normal write operations and connecting it to VCC inhibits writes to the protected memory; if left undriven it is internally pulled down to GND, and Microchip recommends driving it to a known state. |
| 8 | VCC | power_in | Device power supply, specified from 1.7V to 5.5V; operation at invalid VCC voltages may produce spurious results and should not be attempted. |
