MICRF112 300MHz to 450MHz, +10dBm, 1.8V to 3.6V, ASK/FSK Transmitter with Shutdown General Description Features The MICRF112 is a high-performance, easy to use, true ? 1.8V to 3.6V supply voltage range ?Data-In, RF-Out,? ASK/FSK, phase-locked loop (PLL) ? Up to +10dBm output power (CW) based, transmitter IC for applications in the 300MHz to ? 6.9mA supply current at 1kbps ASK (50% Manchester) 450MHz frequency range. These applications include ? 11.5mA supply current at +10dBm (FSK/CW) remote keyless entry (RKE) and tire pressure monitoring (TPMS). The device needs only a low-cost crystal to ? 1?A shutdown supply current precisely set the desired RF frequency, and a few external ? Data rates up to 50kbps ASK, 10kbps FSK components for matching the power amplifier output to the ? Crystal or ceramic resonators sets RF frequency antenna. ? ?40?C to +125?C temperature range The MICRF112 operates over the 1.8V to 3.6V operating ? 10-pin MSOP (3.0mm x 4.9mm) range and delivers +10dBm (CW) output power into a 50? ? 10-pin Ultra-Thin DFN (2mm x 2mm x 0.4mm) load, while consuming 11.5mA of supply current from a 3.0V power supply. In ASK mode, the device consumes 6.9mA of supply current at a data rate of 1kbps Applications (Manchester 50%). It features a low-power shutdown mode in which the device typically consumes 50nA of ? Remote keyless entry systems (RKE) supply current. This makes it an ideal solution for battery ? Remote control (STB, HVAC, and appliances) powered applications. ? Garage door openers (GDO) The MICRF112 is rated for the ?40?C to +125?C ? Tire pressure monitor systems (TPMS) temperature range, and is available in 10-pin MSOP and ? Outdoor weather stations 10-pin Ultra-Thin DFN packages. For automotive applications, where AEC-Q100 qualification is required, ? Security/Alarm systems consider the MAQRF112. For ASK-only applications that ? Lighting and fan remote controls do not require shutdown, consider the MICRF113 in ? Doorbells SOT23-6. ?

These applications include ? 11.5mA supply current at +10dBm (FSK/CW) remote keyless entry (RKE) and tire pressure monitoring (TPMS). The device needs only a low-cost crystal to ? 1?A shutdown supply current precisely set the desired RF frequency, and a few external ? Data rates up to 50kbps ASK, 10kbps FSK components for matching the power amplifier output to the ? Crystal or ceramic resonators sets RF frequency antenna. ? -40?C to +125?C temperature range The MICRF112 operates over the 1.8V to 3.6V operating ? 10-pin MSOP (3.0mm x 4.9mm) range and delivers +10dBm (CW) output power into a 50? ? 10-pin Ultra-Thin DFN (2mm x 2mm x 0.4mm) load, while consuming 11.5mA of supply current from a 3.0V power supply. In ASK mode, the device consumes 6.9mA of supply current at a data rate of 1kbps Applications (Manchester 50%). It features a low-power shutdown mode in which the device typically consumes 50nA of ? Remote keyless entry systems (RKE) supply current. This makes it an ideal solution for battery ? Remote control (STB, HVAC, and appliances) powered applications. ? Garage door openers (GDO) The MICRF112 is rated for the -40?C to +125?C ? Tire pressure monitor systems (TPMS) temperature range, and is available in 10-pin MSOP and ? Outdoor weather stations 10-pin Ultra-Thin DFN packages. For automotive applications, where AEC-Q100 qualification is required, ? Security/Alarm systems consider the MAQRF112. For ASK-only applications that ? Lighting and fan remote controls do not require shutdown, consider the MICRF113 in ? Doorbells SOT23-6. ?
