23K640T-I

Microchip Tech · SRAM · SOIC-8

23K640T-I from Microchip Tech, in a SOIC-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 CS input Chip Select input: a low level selects the device, and a high level deselects it and forces it into Standby mode.
2 SO output Serial Data Output: data is shifted out after the falling edge of SCK, and SO goes to high-impedance when the device is deselected or HOLD is low.
3 NC unconnected Labeled NC on the pin diagram and not listed in the pin function table; the datasheet gives no function for this pin.
4 VSS power_in Ground reference for the device.
5 SI input Serial Data Input: receives instructions, addresses and data, latched on the rising edge of SCK.
6 SCK input Serial Clock input: SI is latched on the rising edge of SCK and SO is updated after the falling edge.
7 HOLD input Hold input: must be held high when unused, and pulling it low while SCK is low pauses serial communication and tri-states SO.
8 VCC power_in Supply voltage: 2.7 V to 3.6 V for the 23K640 (I and E temperature ranges), per parameter D001.
