In addition to flash cards, Samsung provides a comprehensive portfolio of next-generation component technologies designed foradvanced imaging devices. The following block diagram shows the architecture of a typical digital camera. Blue-shaded blocks represent components offered by Samsung. Click on a block and information about that component will appear below the diagram.

eMMC-based storage solutions

eMMC is a type of Fusion Memory, and a standard for embedded memory devices that contain both data storage element (such as NAND flash memory) and controller for element integrated on the same silicon die. This results in several advantages, such as reduced development time and easier integration of the memory block in the overall system; ultimately leading to a much shorter time-to-market for the product. Samsung's eMMC solution consists of three components - the MMC (multimedia card) interface, the flash memory, and the flash memory controller. It is offered in the industry-standard BGA package.

moviMCP

is a new architecture of eMMC that is presently under development. It eliminates the need to develop interface software for all types of NAND memory by integrating the embedded controller onto the memory chip and providing an easy-to-use memory solutions package for high-speed data transmissions by devices such as mobile phones. moviMCP also eliminates the need for a memory expansion slot by stacking several memory functions vertically, resulting in a very small footprint for the end memory devices. As an example, moviMCP can be deployed to store the code for an application in the SLC NAND/NOR and DRAM memory, whereas the data can be stored in the eMMC memory in a device.

Key specifications of Samsung eMMC v4.41-based storage solutions are listed below:

  • Densities: 2 GB to 64 GB
  • Supported bus widths: x1, x4, or x8
  • Supported interface voltages: 1.8 V or 3.3 V

Microcontroller

Common digital still/video cameras require a microcontroller (MCU) for functions such as operating the flash and controlling the electrical motor that operates the optical zoom lens on the camera. The MCU typically operates under the control of a higher and more powerful processor (most commonly, a Digital Signal Processor (DSP)).

Samsung comprises a large array of MCUs for deployment on a vast variety of applications. Starting from basic 4-bit MCUs, Samsung MCUs range right up to 32-bit ARM-based RISC MCUs with best-in-class quality of on-chip flash, SRAM, and inbuilt CAN interfaces. Samsung has an entire range of products based on the industry-standard ARM Cortex cores, which deliver exceptional computing power at significantly lower power consumption levels.

While low-end MCUs with 8-bit cores are used as general-purpose, low frequency controllers, mid-range and high-end cores are targeted at specific segments, such as high-speed, high performance, and low power applications. Samsung provides extensive software support, including a custom-designed C compiler for Samsung MCUs, to help accelerate software development for products on the platform.

Key specifications of Samsung controllers are listed below:

  • On-chip memories: Up to 32 KB RAM and up to 1 MB ROM
  • On-chip interfaces: UART, USART, SPI, I2C, USB, CAN, and so on.
  • On-chip peripherals: Timers, counters, LCD controllers, ADCs, PWM generators, and so on.

CMOS Image Sensors

Consumers seeking the very best quality photos and videos choose digital single-lens reflex (DSLR) cameras and compact digital still cameras (DSC). Samsung CMOS image sensor (CIS) solutions enable these cameras to offer leading resolutions with excellent low-light performance for both snapshots and video.

Ultra-sharp, ultra-clear images

Samsung CIS solutions offer high resolutions to help ensure that images are tack-sharp, capturing fine detail and textures. Samsung's proprietary Back Side Illumination (BSI) technology enables increased pixel sensitivity to produce bright, low-noise pictures and video in a variety of lighting conditions.

Fast frame rates

Samsung image sensors help give consumers professional-grade photo shoot capabilities. Fast frame rates enable cameras to capture still images the moment the shutter is pressed - including multiple frames in rapid succession. FHD/ HD, full field-of-view video technology lets consumers capture moving images in stunning detail.

Low power

Samsung CIS solutions use the latest process technologies as well as optimized sensor architectures for low-power operation that enables consumers to increase the number of photos and videos they take on a single battery charge.

Collaborate with a technology leader in camera sensors

As camera technology rapidly evolves, it's important to work with a company like Samsung. We understand exacting design requirements for digital cameras, and are constantly striving to optimize sensors to deliver low-light technology for use in as many potential deployments as possible.

PMIC

Samsung has a wide array of power management solutions designed specifically for imaging devices, such as digital still/video cameras. These solutions offer advanced, flexible, and customizable power management features, such as programmable output voltages, and support for low-power modes, that can be efficiently leveraged by the imaging device's controller or processor. The following list presents some of the key features of Samsung's advanced power management ICs:
