HS4456
H SUN · RF Transceiver ICs · SOT-23-6
HS4456 from H SUN, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | XTLOUT | output | Crystal oscillator output; it works with the XTLIN pin and an external crystal or ceramic resonator (13.56 MHz reference in the typical conditions), with 18 pF maximum capacitance from each crystal pin to ground. |
| 2 | VSS | power_in | Negative power supply pin (ground); the datasheet gives the operating supply range as 1.8 to 3.6 V between VDD and VSS. |
| 3 | PAOUT | output | RF signal output, delivering up to +13 dBm at 315 MHz and +12 dBm at 433.92 MHz into a 50 Ω load. |
| 4 | ASK | input | Data input for ASK/OOK modulation; the logic high threshold is 0.8×VDD minimum and the logic low threshold is 0.2×VDD maximum. |
| 5 | VDD | power_in | Positive power supply pin, operating from 1.8 V to 3.6 V (absolute maximum 4.0 V). |
| 6 | XTLIN | input | Crystal oscillator input; it works with the XTLOUT pin and an external crystal or ceramic resonator. |
