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 update the value of the Occupancy Attribute in the Occupancy Sensing cluster.	PC6 (13)	INPUT - Digital (Active Low) Requires Hardware Debounce Internal pull-up on the EM357 is enabled.
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 Joined: the LED will be SOLID. Down: the application is never in the Network Down state, as it will persistently scan for a network if its not joined to one. Scanning: the LED will BLINK. Identify On reception of an Identify command, the LED will BLINK for the specified Identify Time.	PA4 (26)*	OUTPUT - Digital (Active High)
9	Reserved (PTI_DATA)		PA5 (27)*
10	JTDO		PC2 (33)
11	JTCK		(32)
12	JTD		PC3 (34)
13	JTMS		PC4 (35)
14	JRST		PC0 (40)
15	RXD		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)#	OUTPUT - Digital (Active High) 1k Hz Frequency
17	TXD		PB1 (30)	UART Serial TX
18	GND
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)*	INPUT - Digital (Active Low) Internal Pull-up Requires Hardware Debounce
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) Part Number: APDS-9006 https://www.broadcom.com/products/optical-sensors/ambient-light-photo-sensors/apds-9006 RLS firmware is designed to interpret 0-1V analog signal as 0-1000 lux (linear relationship). Note: MMB has not completed testing with a Lux meter to verify the accuracy of this sensor. Customer is free to use any other sensor that outputs 0-1V as 0-1000 lux (linear relationship).
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)*	INPUT - Digital (Active Low) Internal Pull-up Requires Hardware Debounce Hold low for >5 seconds to initiate Factory Reset
