This topic defines the device electrical performance specifications, including absolute
maximum ratings, and operating conditions, which are useful in deploying the device with
optimal processing capabilities and high efficiency.
## Absolute maximum ratings
Source: [https://docs.qualcomm.com/doc/80-78830-1/topic/electrical-specifications.html](https://docs.qualcomm.com/doc/80-78830-1/topic/electrical-specifications.html)
Do not exceed the absolute maximum ratings mentioned in [Table : Absolute maximum ratings](https://docs.qualcomm.com/doc/80-78830-1/topic/electrical-specifications.html#absolute-maximum-ratings__table_zc4_qsl_qbc).
Warning: If ratings are exceeded, this may cause permanent
damage to the device.
Functionality and reliability are guaranteed only within the conditions described in
[Operating conditions](https://docs.qualcomm.com/doc/80-78830-1/topic/electrical-specifications.html#operating-conditions)
Table : Absolute maximum ratings
| Parameter | Description | Min | Max | Unit |
| --- | --- | :---: | :---: | :---: |
| VDD33 | Power input voltage | -0.3 | 3.63 | V |
| VDDIO1, VDDIO 2 | I/O port voltage | -0.3 | 3.63 | V |
| ESD Protection (HBM) | – | – | 2,000 | V |
| Ts | Storage temperature [^1^](https://docs.qualcomm.com/doc/80-78830-1/topic/electrical-specifications.html#fntarg_1_absolute-maximum-ratings)[^2^](https://docs.qualcomm.com/doc/80-78830-1/topic/electrical-specifications.html#fntarg_2_absolute-maximum-ratings) | -40 | 125 | °C |
[^1^](https://docs.qualcomm.com/doc/80-78830-1/topic/electrical-specifications.html#fnsrc_1_absolute-maximum-ratings) The storage temperature range applies when
the device is in the OFF state (the device is not assembled in any
platform and is not electrically connected to any voltage or I/O
signals). Damage may occur when the device is subjected to this
temperature for any length of time.
[^2^](https://docs.qualcomm.com/doc/80-78830-1/topic/electrical-specifications.html#fnsrc_2_absolute-maximum-ratings) For devices shipped in
tape and reel, the storage temperature range is [+15°C~+35°C] and
< 90% relative humidity (RH). QTI recommends allowing the device
to return to ambient room temperature before usage.
## Operating conditions

Operating conditions include parameters such as power supply voltage, power distribution
impedances, and thermal conditions. The QCC743M meet all performance
specifications listed in the following table when used within the operating
conditions.

| VDDIO1, VDDIO 2 (3.3 V) | I/O port voltage | 2.97 | 3.3 | 3.63 | V |
| VDDIO1, VDDIO 2 (1.8 V) | I/O port voltage | 1.62 | 1.8 | 1.98 | V |

QCC743M can operate in four power states as shown below to maximize power
saving:
- Active – Continuous transmitting or receiving on
connection to AP
- Idle – No active transmitting or receiving. CPU is in
idle state.
- Deep Sleep – Wi-Fi/CPU/Peripherals power off. This is DTIM power saving mode.
- Hibernation – No connection to AP.
- Shut down – The chip is completely shut down.
Note: Preliminary projections are developed based on the best knowledge of
the platform and are subject to change.

| --- | --- | --- | --- | --- |
| Active | MCU Active & Rx Active | 38 | mA | MCU 160 MHz, XCLK 40 MHz, BCLK 80 MHz, Flash 40 MHz |
| Active | Tx Active | 318 | mA | MCS0, Tx Power = +19 dBm |
