The RAW series cameras have only one mcu as an auxiliary control chip and do not contain an ISP module. Therefore, its functions are a subset of the MV series. Whether or not the feature is applicable to RAW series cameras will be listed in the description of each feature later on.

In addition, RAW series cameras support SDA (Sensor direct access) mode, which will be detailed in the last section of this article.
      
To facilitate rapid development, we provide hardware datasheet , register manuals and drivers for embedded platforms, demos.

=== Special note for RAW series camera ===
+
=== Special note for RAW series camera Trigger Delay ===
−
RAW series cameras have only one MCU as the auxiliary chip. Normal mode and SDA mode can be switched by [[Mv mipi i2c.sh user guide#mcubypass|mcubypass]] command.
+
For RAW series cameras, the trigger signal needs to be forwarded to the sensor by the MCU, and this forwarding has a fixed delay of about 950ns.
   −
==== Normal mode ====
+
=== Document History ===
−
In normal mode, the motherboard cannot access the sensor directly. the MCU provides the initial configuration of the sensor and the configuration of various functions. For different embedded platforms, we have provided corresponding drivers, scripts, and demos.
     −
The functions are described in the above description of this article.
+
* 2025-03-14
   −
==== SDA mode ====
+
Add description about GMAX4002M.
−
SDA mode is short for Sensor Direct Access, when the MCU no longer has any control over the i2c of the sensor. The user controls the sensor directly.
     −
Meanwhile, in order to provide necessary system information, mode switching, and configuration of trigger signals, the MCU itself still provides i2c interface to the outside.
+
* 2025-01-07 
   −
For example, the RAW series cameras has two i2c addresses in SDA mode: 0x30 is the i2c address of the sensor and 0x3b is the i2c address of the MCU.
+
1. Remove the description of the SDA mode for the RAW series products.
   −
In SDA mode, the drivers and demos we provided are no longer applicable, only some [[Mv mipi i2c.sh user guide|mv_mipi_i2c.sh]] instructions and [[MV Series MIPI Camera Register Map|registers]] are available.
+
2. Add a description of the external trigger mode for the RAW series based on the upgrade achievements.
   −
==== Trigger Delay ====
+
* 2024-08-27
−
For RAW series cameras, the trigger signal needs to be forwarded to the sensor by the MCU, and this forwarding has a fixed delay of about 850ns.
+
 
−
<br />
+
Add a description of the pulse trigger mode. Ensure it aligns with the values in the `trgmodecap` register.
