Module Specification Notes:

Note 2 With I2C interface selected, pull-up resistors on I2C SDA and I2C SCL must be connected externally as

per I2C standard.

Note 3 SPI interface (master) consists of SPI MOSI, SPI MISO, and SPI CLK. SPI CS is created by using any

spare SIO pin within the smartBASIC application script allowing multi-dropping.

Note 4 The BL652 module comes loaded with smartBASIC runtime engine firmware but does not come

loaded with any smartBASIC application script (as that is dependent on customer-end application or

use). Laird provides many sample smartBASIC application scripts covering the services listed.

Additional BLE services are being added every quarter.

Note 5 Use of the internal DCDC convertor or LDO is decided by the underlying BLE stack.

Note 6 These figures are measured on the BL652-Sx-xx.



Deep Sleep current for BL652-Sx-xx ~400nA (typical)



Standby Doze current for BL652-xx-A1 1.2uA (typical)

Note 7 PWM output signal has a frequency and duty cycle property. PWM output is generated using

dedicated hardware in the chipset. There is a trade-off between PWM output frequency and

resolution.

For example:



PWM output frequency of 500 kHz (2 uS) results in resolution of 1:2.



PWM output frequency of 100 kHz (10 uS) results in resolution of 1:10.



PWM output frequency of 10 kHz (100 uS) results in resolution of 1:100.



PWM output frequency of 1 kHz (1000 uS) results in resolution of 1:1000.

Refer to the smartBASIC user guide for details. It’s available from the Laird BL652 product page.
