MICRF112YMM from Microchip Tech, in a MSOP-10. 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 | ASK | input | ASK data input; digital input with VIH 0.8×VDD and VIL 0.2×VDD, max leakage 0.05µA. |
| 2 | XTLIN | input | Reference oscillator input connection for the Pierce crystal oscillator (crystals 9.375MHz to 14.0625MHz). |
| 3 | XTLOUT | output | Reference oscillator output connection to the crystal; the FSK capacitor is connected between this pin and XTAL_MOD. |
| 4 | VSS | power_in | Ground. |
| 5 | XTAL_MOD | passive | Reference oscillator modulation port for FSK operation, connected internally to the open-drain switch driven by the FSK pin. |
| 6 | FSK | input | FSK data input driving the gate of the open-drain switch on XTAL_MOD; digital input with VIH 0.8×VDD and VIL 0.2×VDD. |
| 7 | EN | input | Chip enable, active high; EN = VSS gives shutdown with 0.05µA typical (1µA max) standby current. |
| 8 | VSSPA | power_in | Power amplifier ground. |
| 9 | PAOUT | output | Power amplifier output delivering up to +10dBm into a matched 50Ω load; absolute maximum voltage +7.2V. |
| 10 | VDD | power_in | Positive power supply, 1.8V to 3.6V operating range (4.3V absolute maximum). |
