The MICRF112 is a versatile, true “Data-In, RF-Out,” ASK/FSK transmitter IC designed for applications requiring precise frequency control and efficient power usage. It operates in the 300MHz to 450MHz range, needing only a crystal and a few external components. With its low power shutdown mode and wide operating voltage range (1.8V to 3.6V), the MICRF112 is well-suited for remote keyless entry (RKE), tire pressure monitoring (TPMS), and other wireless control systems. It is available in MSOP and Ultra-Thin DFN packages.
