"AR0330CM-Datasheet.pdf 提供了ON Semiconductor的AR0330CM 1/3英寸CMOS数字图像传感器的详细规格和技术参数。" AR0330CM是ON Semiconductor公司推出的一款1/3英寸CMOS（互补金属氧化物半导体）数字图像传感器，具备2304像素宽度（H）和1536像素高度（V）的主动像素阵列。这款传感器设计用于支持高分辨率的图像捕捉，能够实现3.15百万像素（2048(H)×1536(V)）的数码静态图像拍摄以及1080p60帧率加20%电子图像稳定（EIS）的高清视频模式。它整合了一系列先进的片上相机功能，包括窗口裁剪、镜像、列和行子采样模式以及快照模式。关键性能参数如下： 1. 光学格式：1/3英寸（对角线6.0mm），整个阵列尺寸为6.09mm。在4:3的静止图像模式下，有效尺寸为5.63mm；在16:9的高清图像模式下，有效尺寸为5.82mm。 2. 活动像素：整个阵列为2304(H)×1536(V)，对应物理尺寸为5.07mm(H)×3.38mm(V)。在4:3的静止模式下，像素数减小至2048(H)×1536(V)；在16:9的高清模式下，像素数调整为2304(H)×1296(V)。 3. 像素大小：每个像素为2.2微米×2.2微米。 4. 颜色滤波阵列：采用RGB拜耳滤波器，用于彩色图像的捕捉。 5. 快门类型：支持电子滚动快门（ERS）和全局重置快门（GRR），提供灵活的曝光控制。 6. 输入时钟范围：6到27MHz，可适应不同应用场景的需求。 7. 输出时钟最大值：高达196百万像素/秒（4-lane HiSPi或MIPI），确保高速数据传输。 8. 输出视频：4-lane HiSPi配置下，可以实现2304×1296分辨率的图像在60fps和30fps下的传输。功耗方面，60fps时功率低于450mW（VCM为0.2V），30fps时功率低于300mW（VCM同样为0.2V）。 AR0330CM这款传感器因其高效能、高分辨率和多种模式支持，适用于各种需要高质量图像捕获和处理的领域，如安防监控、无人机、智能手机摄像头、工业检测等。其低功耗特性尤其适合移动设备和需要长时间运行的系统。此外，通过集成的EIS功能，它能提供更稳定的视频录制体验，减少因手抖或其他运动引起的图像模糊。

1. Turn on V

2. After 100 ms, turn on V

supply.

3. After 100 ms, turn on V

power supply.

4. After 100 ms, turn on V

_IO power supply.

5. After the last power supply is stable, enable

EXTCLK.

6. Assert RESET_BAR for at least 1 ms.

7. Wait 150,000 EXTCLK periods (for internal

initialization into software standby.

8. Write R0x3152 = 0xA114 to configure the internal

9. Write R0x304A = 0x0070 to start the internal

10. Wait 150,000 EXTCLK periods.

11. Configure PLL, output, and image settings to

desired values.

12. Wait 1ms for the PLL to lock.

13. Set streaming mode (R0x301A[2] = 1).

Notes:

1. A software reset (R0x301A[0] = 1) is not necessary after the procedure described above since a Hard Reset will automatically triggers

a software reset. Independently executing a software reset, should be followed by steps seven through thirteen above.

2. The sensor must be receiving the external input clock (EXTCLK) before the reset pin is toggled. The sensor will begin an internal initialization

sequence when the reset pin toggle from LOW to HIGH. This initialization sequence will run using the external input clock. Power on default

state is software standby state, need to apply two-wire serial commands to start streaming. Above power up sequence is a general power

up sequence. For different interface configurations, MIPI, and Parallel, some power rails are not needed. Those not needed power rails

should be ignored in the general power up sequence.

1. External clock settling time is component-dependent, usually taking about 10–100 ms.

2. Hard reset time is the minimum time required after power rails are settled. In a circuit where Hard reset is held down by RC circuit, then the

RC time must include the all power rail settle time and Xtal settle time.

3. It is critical that V

_PLL is not powered up after the other power supplies. It must be powered before or at least at the same time as the

others. If the case happens that V

_PLL is powered after other supplies then sensor may have functionality issues and will experience high

current draw on this supply.

4. V

_MIPI is tied to V

_PLL in the both the CLCC and CSP packages and must be powered to 2.8 V. The V

_HiSPi and V

_HiSPi_TX

supplies do not need to be turned on if the sensor is configured to use the MIPI or parallel interface.
