JSM500R from JSMSEMI, in a SSOP-16-150mil. 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 | RO1 | input | External crystal reference input for the frequency synthesizer, with reference input amplitude 0.2 to 1.5 VP-P and fREF of 13.52313 MHz at 433 MHz or 9.81713 MHz at 315 MHz. |
| 2 | GND | power_in | Ground reference; all device voltages are referenced to GND. |
| 3 | ANT | input | RF input; recommended maximum input power is 0 dBm, absolute maximum is 10 dBm, and DC voltage must stay between -0.3 V and VDD+0.3 V. |
| 4 | GND | power_in | Ground reference; all device voltages are referenced to GND. |
| 5 | VDD | power_in | Supply voltage, recommended 2.0 V to 5.0 V; absolute maximum rating is 6 V. |
| 6 | SQ | input | Squelch enable: low enables the squelch function, which suppresses DO output for signals whose code rate exceeds the squelch threshold; high disables squelch. |
| 7 | SEL0 | input | Bit-rate select bit 0; together with SEL1 it sets the recommended maximum code rate, and it selects the recommended CAGC capacitor value. |
| 8 | SHDN | input | Power-save enable: high puts the device in power-save mode with total current below 1 µA; low gives normal operation. |
| 9 | GND | power_in | Ground reference; all device voltages are referenced to GND. |
| 10 | DO | output | Decoded data output; output is specified at 0.8VDD high (235 µA) and 0.2VDD low (400 µA), with rise time 600 ns and fall time 250 ns at 15 pF load. |
| 11 | SEL1 | input | Bit-rate select bit 1; together with SEL0 it sets the recommended maximum code rate, and it selects the recommended CAGC capacitor value. |
| 12 | CTH | passive | Reference voltage terminal; the datasheet test conditions use a 0.1 µF capacitor on this pin. |
| 13 | CAGC | passive | AGC capacitor terminal; charged with 120 µA at power-up and discharged with 600 µA during fast stabilization, with recommended value 4.7 µF at SEL1:SEL0 = 00 down to 0.47 µF at SEL1:SEL0 = 11. |
| 14 | RSSI | output | Received signal strength indicator output, with output voltage 0.5 V to 1 V and typical output current 400 µA. |
| 15 | NC | unconnected | No connection; the pin is listed as empty ('空') in the pin definition table. |
| 16 | RO2 | input | External crystal reference input 2; the datasheet gives no separate electrical limits for this pin. |
