Chapter 1. Overview

The CM6125/C6125 SOM is a cost-effective AI computing module to provide highly intelligent experiences for IoT

products. Its design is based on the Qualcomm® QCM6125/QCS6125 platform which can be taken as a successor

of Snapdragon 660 platform. Powered by the third generation Qualcomm AI Engine: Adreno 610 GPU and

Hexagon 686 DSP (dual-HVX512), the 6125 platform can provide advanced on-device imaging and computing

like smart cropping, 3D face recognition, and object detection. It is an ideal platform for customers to design

smarter and more engaging products to the market.

Symbol Description

AI Analog input

AO Analog output

B Bidirectional digital with CMOS input

DI Digital input (CMOS)

DO Digital output (CMOS)

H High-voltage tolerant

nppdpukp

Programmable pull resistor. The default pull direction is indicated using capital letters and is a prefix to other programmable options:

NP: pdpukp = default no-pull with programmable options following the colon (:)

PD: nppukp = default pull-down with programmable options following the colon (:)

BATT_ID is used for the different battery pack (ranges from 7.5k to 450kohm) identification.

BATT_THERM reports the temperature of the battery pack to system. In general, it is recommended to use NTC

100K 1% B=4350 thermistor in the battery pack, and 100Kohm resistance for the non-battery device.

Default settings for USB_PHY_PS and FORCED_USB_BOOT_SEL has been defined in the SOM.

The EDL mode will be enabled once SM_FORCE_USB_BOOT pulled up to 1.8V.

2.6. QCM6125 GPIO interface

These GPIOs of QCM6125 are available as Qualcomm universal peripheral (QUP) interface ports that can be

configured for UART or/and SPI or/and I2C or/and I3C operation (Note: Only one protocol type can be selected in

each QUP engine at the same time).

There are 9 x QUP engines (Serial Engine item in below table).

I2C is a two-wire bus interface that can be routed to multiple devices; each bus line needs to be supplemented by

a 2.2kΩ pull-up resistor.

Qualcomm battery gauge is a hybrid of voltage and current based state of charge. The core of PMI632 Qualcomm

battery gauge hardware consists of accumulator, which periodically samples, accumulates, and saves Vbatt and

Ibatt values into PMIC register to read and process SoC (System on Chip).

The same hardware is reused for an online battery ESR estimation, where V and I readings are run and saved to

record pre-ESR and ESR pulse Vbatt and Ibatt values. The software reads the registers for ESR estimation.
