ST25DV64KC-IE8T3

STMicroelectronics · RF Chips · TSSOP-8

ST25DV64KC-IE8T3 from STMicroelectronics, 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 V_EH power_out Energy harvesting analog output pin used to power external components.
2 AC0 passive Antenna coil connection AC0 for the RF interface.
3 AC1 passive Antenna coil connection AC1 for the RF interface.
4 VSS power_in Ground reference for the device.
5 SDA bidirectional Serial data I/O of the two-wire I2C interface (up to 1 MHz protocol).
6 SCL input Serial clock input of the two-wire I2C interface.
7 GPO output Interrupt output, open-drain on this IE version; it is released (high impedance) when not driven and needs an external pull-up.
8 VCC power_in Supply voltage input; the device operates from a single supply of 1.8 V to 5.5 V.
