Usually, the unused digital pins can be set as output pins and require no external processing if they can be configured for GPIO functions. If they cannot be configured for GPIO functions, then extend the pin to the ground with pull-down resistor, resistance value 4.7k ohm.

Hi3531 does not support AAC LC 8K bps and ARM compression / decompression functions.

Hi3716C supports 2D/3D GPU mechanism and OpenGL ES 2.0/1.1/1.0 OpenVG 1.1.

There are OSD I/F and OSD IC connections reserved in LR36B14. Customers need to select an OSD IC and design the related circuits.

LR36B16 OSD supports five languages: English, French, Spanish, Portugal and simplified Chinese. And if you intend to use Simplified Chinese character fonts, you will need to apply to the agency in China and pay a loyalty.

 It requires 24C16 16Kbyte I2C I/F EEPROM.

Image abnormality will not occur if the voltage remains within the range given in the specifications (2.7 to 2.9V).

The original manufacturer replied that VrefY & VrefC share the same pins; therefore, they can only be adjusted together.

There are two build-in UARTs in the ISP; one is the old ISP communication interface and the other is the MCU communication interface.

In addition to the replacement from AFE to Sierra, there are many new functions as listed below:
1. Customized OSD menu character string
(1) Changeable menu character string: “ATR”, “NR”, “NR MODE”, “IR OPTIMIZER”
(2) Supported languages: 8 languages ( EN / JP / CN / POR / GE / RUS / FR / ES )
(3) Increased character limit to 16 characters.

2. Customized OSD ME Shutter/AGC setting:
(1) Shutter/AGC value can be assigned
Shutter: 1/50 - 1/65534, 1/100000
AGC : 0.00 - 44.80
(2) Eight sets of default values can be assigned (1-8)

3. OSD button for activating white spot compensation function
(1) Press OSD enter and hold to activate the white spot compensation function.
(2) This function can only be operated when the OSD menu is closed.

4. IR-LED collaborative operation
(1) “External mode” is added with function of DayNight
(2)Utilize CDS sensor to control day/night status
(3) ISP compensates automatically according to the conditions of IR-LED illumination.
