MICRF213AYQS-TR

Microchip Tech · RF Transceiver ICs · QSOP-16-150mil

MICRF213AYQS-TR from Microchip Tech, in a QSOP-16-150mil. 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 RO1 passive Reference resonator input connection to the Colpitts oscillator stage, which may also be driven by an external reference signal of 1.5V p-p amplitude maximum.
2 GNDRF power_in Negative supply connection associated with the ANT RF input.
3 ANT input RF signal input from the antenna, internally AC-coupled; a matching network with an inductor-to-RF ground is recommended to improve ESD protection.
4 GNDRF power_in Negative supply connection associated with the ANT RF input.
5 VDD power_in Positive supply connection for all chip functions (operating range 3.0V to 3.6V per the operating ratings).
6 SQ input Squelch control logic input with an active internal pull-up when not shut down.
7 SEL0 input Logic control input with active internal pull-up, used in conjunction with SEL1 to control the demodulator low-pass filter bandwidth.
8 SHDN input Shutdown logic control input with active internal pull-up.
9 GND power_in Negative supply connection for all chip functions except the RF input.
10 DO output Demodulated data output (driving capability of 0.4mA per the application section).
11 SEL1 input Logic control input with active internal pull-up, used in conjunction with SEL0 to control the demodulator low-pass filter bandwidth.
12 CTH passive Demodulation threshold voltage integration capacitor connection; an external capacitor is tied across CTH and GND, with values above 1nF recommended.
13 CAGC passive AGC filter capacitor connection; a CAGC capacitor normally greater than 0.47uF is connected from this pin to GND.
14 RSSI output Received signal strength indication output from a buffer with 200 ohms typical output impedance.
15 NC unconnected Not connected; the datasheet specifies that this pin should be connected to ground.
16 RO2 passive Reference resonator input to the Colpitts oscillator stage, 7pF in parallel with a low-resistance MOS switch-to-GND during normal operation, and driven by the startup excitation circuit during startup.
