1/4.2-inch 5 MP CMOS Digital Image Sensor AR0544
Brand: onsemi
Publication Order Number: AR0544-PD/D
Document Revision: December, 2024 - Rev. 4
General Description
The onsemi AR0544 is a stacked 1/4.2-inch back side illuminated (BSI) CMOS active-pixel digital image sensor. It features a pixel array of 2592 x 1944 (2608H x 1960V including border pixels) and enhanced Near-Infrared (NIR) response. The sensor incorporates sophisticated on-chip camera functions such as Wake on Motion (WOM), context switching, and multiple subsampling modes. It is programmable via a simple I2C interface and offers very low power consumption. The AR0544 utilizes onsemi’s low-noise CMOS imaging technology and can generate full resolution images at up to 60 frames per second (fps) in 10-bit linear mode, and 30 fps in line-interleaved high dynamic range (LI-HDR) mode. It also supports enhanced Dynamic Range (eDR) mode.

Block Diagram
The AR0544 block diagram shows the sensor's internal structure, divided into an 'Image sensor core' and 'Signal Processing' sections. The 'Image sensor core' includes the Row Driver, Pixel Array, Analog Signal Chain, ADC Gain Chain, Temperature Sensor, and Gain Control. Input signals like EXTCLK, XSHUTDOWN, GPIOs, I2C (SCL, SDA), and power supplies (VAA_ANA_ACORE, VAA_ANA_PIX, VDD_DIG_ACORE, VAA18_ANA_ACORE) connect to this core. The 'Signal Processing' section contains Timing Control, PLL, Test pattern Generator, Data Correction, Digital Gain, LSC (Lens Shading Correction), FIFO & Optional compression, and MIPI output. The output stage provides MIPI serial data output, supported by power supplies VDD_DIG_DCORE, VDD_DIG_PLL, VDD_DIG_PHY, and VDDIO1V8.
