Product Details
MICRF302YML-TR — Four-Input QwikRadio Parallel Encoder
MICRF302YML-TR from Microchip Technology is a MICRF302-family encoder for low-data-rate RF control links. Four parallel switch inputs are converted into a serial Manchester-coded baseband output for a companion transmitter.
Electrical, pin and package characteristics below are from the manufacturer's MICRF302 data sheet, which explicitly lists MICRF302YML. The additional catalog -TR suffix was not independently confirmed in that document and must be checked before release.
Overview
The MICRF302 accepts switch states on D0 through D3, filters short input glitches, assembles a packet containing a stored device address and data, adds an 8-bit CRC, and drives an RF transmitter through TXEN and DOUT. A trimmed on-chip oscillator supplies timing without a separate clock component. This is an encoder/baseband device, not a stand-alone RF transmitter or receiver.
Key Advantages
D0–D3 accept push-button or logic signals and include pull-ups and deglitching.
Address, data and an 8-bit CRC are assembled into serial packets for a companion transmitter.
SEL0 and SEL1 select 600 bps, 1 kbps, 3 kbps or 4.8 kbps.
The on-chip oscillator avoids a separate external clock component.
Feature Summary
Four parallel inputs, Manchester-coded DOUT and transmitter-enable TXEN.
Short switch pulses are rejected by approximately 8 ms deglitch filtering.
An internal 20-bit address helps distinguish nearby encoders.
1.8–3.6 V operation across the specified −40 °C to +85 °C range.
Package & Footprint
The original catalog package is 10-VFDFN Exposed Pad, 10-MLF®. The manufacturer's MICRF302YML ordering table identifies a 10-pin 2.5 mm × 2.5 mm MLF® package. The registered 10-MLF® single-name package is used for image tracking; check the manufacturer's 10-pin drawing and exposed-pad guidance before PCB release.
Pin Functions
Use the manufacturer's top-view pin diagram for physical orientation and pad layout.
Key Specifications
| Manufacturer-listed base order | MICRF302YML |
|---|---|
| Catalog order | MICRF302YML-TR; -TR suffix needs independent confirmation |
| Function | Four-input parallel-to-serial RF encoder |
| Operating supply | 1.8 V to 3.6 V |
| Operating temperature | −40 °C to +85 °C |
| Selectable rates | 600 bps, 1 kbps, 3 kbps and 4.8 kbps |
| Input deglitch | Approximately 8 ms pulse rejection |
| Address and check | 20-bit internal address and 8-bit CRC |
| Operating current | 130 µA typical at the data-sheet test condition |
| Manufacturer package | 10-pin, 2.5 mm × 2.5 mm MLF® |
Replacement Considerations
No internal replacement is linked without an exact API-confirmed product and engineering comparison. A substitute must match the four-input behavior, packet format, 20-bit address handling, CRC, data-rate selection, transmitter-enable timing, supply range and 10-pin footprint. A generic RF encoder is not automatically interchangeable.
Manufacturer Information
The Microchip-hosted Micrel MICRF302 data sheet explicitly specifies MICRF302YML with XA02 marking and 10-pin MLF® packaging. It does not independently establish the catalog's added -TR suffix, so verify the reel label or manufacturer ordering record before approval. Technical limits on this page apply to the documented MICRF302YML base device.
Applications
Encode button states for a low-data-rate unidirectional RF link.
Provide switch-input framing for a compatible transmitter and receiver.
Use the stored address and CRC as part of a system-level command link.
Quality & Authenticity
Check the complete catalog order, MICRF302YML base marking, 10-pin package dimensions, lot traceability and -TR logistics suffix against manufacturer-approved records. Confirm the receiver configuration and RF-link behavior through system testing; CRC improves error detection but is not a security authentication feature.
FAQ
Does MICRF302 transmit RF by itself?
No. It provides baseband data and a transmitter-enable signal for a companion RF transmitter.
How are data rates selected?
SEL0 and SEL1 select one of four manufacturer-listed rates from 600 bps through 4.8 kbps.
Is the exact -TR suffix documented here?
No. The consulted manufacturer data sheet lists MICRF302YML; the added catalog suffix requires separate confirmation.
Can this review page be published?
Not yet. The production package JPG is unavailable, and the suffix still needs independent confirmation.
Engineering Notice
Follow the manufacturer's pin diagram, SEL timing, 1.8–3.6 V operating limits and RF-link packet specification. Verify MICRF302YML-TR as an exact order and restore the production 10-MLF JPG before final approval or publication.
