MICRF112YMM

Microchip Tech · RF Transceiver ICs · MSOP-10

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).
