# FSV8023

**Forsinve** · RFID ICs · DFN-8-EP(2x2)

FSV8023 from Forsinve, in a DFN-8-EP(2x2). 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 | VCC | power_in | Supply pin for the 3.3V chip supply, with the datasheet giving a Vdd operating range of 2.7 V to 5.5 V (3.3 V typical). |
| 2 | SCL | bidirectional | I²C bus clock line, which the chip samples on the rising edge and which it can also drive in active mode. |
| 3 | SDA | bidirectional | I²C bus data line, which the chip samples on SCL rising edges and which it can also drive in active mode. |
| 4 | FD | output | Field-detect pin that changes state on RF field presence, valid frame start, and chip selection, and can serve as a handshake signal in pass-through mode. |
| 5 | GND | power_in | Ground reference pin for the chip. |
| 6 | Vout | output | Chip output pin as named in the datasheet, with no further electrical limits stated in the text. |
| 7 | RF1 | passive | Antenna connection pin for the 13.56 MHz RF interface, which connects to the LA-LB antenna pair with an antenna input current limit of 30 mArms. |
| 8 | RF2 | passive | Antenna connection pin for the 13.56 MHz RF interface, which forms the second side of the antenna pair with RF1. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
