# M24SR16-YDW6T

**STMicroelectronics** · RFID ICs · TSSOP-8

M24SR16-YDW6T 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 | RF disable | input | Input that disables RF communication; an external pull-down is required when VCC is above its POR level, and in Dual interface mode it must not be left floating. |
| 2 | AC0 | passive | Antenna coil terminal for connecting the external coil exclusively; no other DC or AC path should be connected. |
| 3 | AC1 | passive | Antenna coil terminal for connecting the external coil exclusively; no other DC or AC path should be connected. |
| 4 | VSS | power_in | Ground, the reference for the VCC supply voltage for all pads, even AC0 and AC1. |
| 5 | SDA | bidirectional | I2C serial data, open drain output that needs a pull-up resistor to VCC. |
| 6 | SCL | input | I2C serial clock input that strobes all data in and out of the device. |
| 7 | GPO | output | Configurable open drain general purpose output (default Session Open) that needs an external pull-up greater than 4.7 kΩ. |
| 8 | VCC | power_in | Supply voltage pin, 2.7 V to 5.5 V, to be decoupled with capacitors (about 10 nF and 100 pF) close to the VCC/VSS pins. |
