AS3933-BTST

AMS · RFID ICs · TSSOP-16

AS3933-BTST from AMS, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CS input Chip select digital input for SPI interface control.
2 SCL input Serial clock input for SDI interface.
3 SDI input Serial data input for SPI configuration.
4 SDO tri_state Serial data output with tri-state control (tri-state when CS is low).
5 VCC power_in Positive supply voltage, operating range 2.4V to 3.6V.
6 GND power_in Ground, negative supply voltage reference.
7 LF3P input Input antenna channel three for low frequency reception in carrier frequency range 15-150kHz.
8 LF2P input Input antenna channel two for low frequency reception in carrier frequency range 15-150kHz.
9 LF1P input Input antenna channel one for low frequency reception in carrier frequency range 15-150kHz.
10 LFN power_in Common ground reference for antenna channels one, two, and three.
11 XIN input Crystal oscillator input (32.768kHz typical) or connected to VCC for external clock mode.
12 XOUT bidirectional Crystal oscillator output (32.768kHz typical) or external clock signal input depending on configuration mode.
13 VSS power_in Substrate supply pad, electrical ground reference.
14 WAKE output Wake-up output IRQ signal, goes high when programmed wake-up pattern is detected.
15 DAT output Demodulated data output or Manchester decoded data from receiver.
16 CL_DAT output Manchester recovered clock output for synchronization of data on DAT pin.
