- All pins have maximum sourcing and sinking current of 4mA.
- EM357 runs off a 3.3V
- (*) indicates ADC capable pin
- (#) indicates PWM capable pin
| Module Pad | Function | Relation to zigbee Features | EM357 GPIO | Hardware Integration Comments |
|---|---|---|---|---|
| 1 | PIR Digital In | When |
| either of the two occupancy inputs are triggered (i.e. this pin or the Ultrasonic Digital In), the Occupancy Sensor Endpoint will inform the network that Occupancy is "true". | PC6 (13) |
| ||
| 2 | Relay Out | When On/Off commands are sent to the Dimmable Light Endpoint, this output will turn on/off accordingly. | PC7 (14) | OUTPUT - Digital (Active High) |
| 3 | Reserved | PA7 (18)# | Reserved for Future PWM | |
| 4 | VCC (3.3 VDC) | |||
| 5 | nCTS / SPI Slave CLK | PB3 (19)# | Reserved for Future PWM | |
| 6 | nRTS / SPI Select (Host Controlled Handshake Line) | PB4 (20)# | Reserved for Future PWM | |
| 7 | nReset, active low | (12) | ||
| 8 | Network Status LED (PTI_EN) | Used as an indicator for two purposes: Network Status

| PA4 (26)* | OUTPUT - Digital (Active High) |
| 9 | Reserved (PTI_DATA) | PA5 (27)* | ||
| 10 | JTDO | PC2 (33) | ||

| PB2 (31) | UART Serial RX | |||
| 16 | PWM Out | When a Level Control command is received, the duty cycle of the PWM pin will be updated to match the intended Level (i.e. 0-100%). | PA6 (29)# |

| 19 | Ultrasonic Digital In | When either of the two occupancy inputs are triggered (i.e. this pin or the PIR Digital In), the Occupancy Sensor Endpoint will inform the network that Occupancy is "true". | PC1 (38)* |
|
| 20 | Illuminance Analog In | The value conveyed via this analog input will be reported to the network by the Light Sensor. | PB7 (41)* | INPUT - Analog (0 - 1.2V) |
| 21 | Network Button | When this input is held low for >5 seconds, the application will execute a Factory Reset, leaving the network and clearing all settings. | PB6 (42)* |
