MICRF112YMM-TR MICROCHIP RF Transmitters

The MICRF112YMM-TR is a low‑power, high‑performance ASK/FSK UHF transmitter IC from Microchip, offered in a 10‑pin MSOP package. For selection, verify supply voltage from 1.8 V to 3.6 V; confirm frequency range between 300 MHz and 450 MHz; note output power up to 10 dBm, data rate up to 50 kbps (ASK) / 10 kbps (FSK), and low current consumption of 6.9 mA (transmitting) with <1 µA shutdown mode for battery‑sensitive designs. Ensure operating temperature from −40 °C to +125 °C. Its PLL‑based “data‑in, antenna‑out” architecture requires few external components. Ideal for remote keyless entry (RKE), garage/gate openers, home automation, security alarms, tire pressure monitoring (TPMS), irrigation systems, lighting control, wireless doorbells, and industrial remote controls.
