RF Transmitter Procurement Notes

Verify that the suffix 'T48A' corresponds to the specific 433-868MHz frequency variant required for your region, as other variants like T39A cover different bands. Confirm the 'I' grade meets industrial temperature requirements. Ensure the TSSOP-14 package matches your PCB footprint and soldering profile specifications before finalizing orders.

RF Transmitter Selection Notes

Select this component when a combined MCU and RF transmitter solution is needed for simple telemetry applications. It is suitable for designs requiring low pin count and integrated power amplification up to 10dBm. Consider the 1.8V to 3.6V supply range for battery-powered projects where power efficiency is critical compared to standard 5V logic devices.

RF Transmitter Part Context

This part belongs to the PIC12LF1840 series, which combines a mid-range 8-bit CPU with an integrated RF front-end. It simplifies design by eliminating external RF components for basic modulation tasks. The series offers various package and frequency options to adapt to different regulatory and form-factor constraints across global markets.

RF Transmitter Replacement Considerations

PIC12LF1840T39AT-I/ST covers 310/433/868/915MHz bands; verify regional frequency compliance.
