Core specifications
BWCE28NH-08G belongs to Baiwei's eMMC product line, which integrates high-performance main control chip and NAND Flash into a single FBGA-153 package.The standard package size is11.5mm×13.0mm×1.0mm, BGA-153 ball grid array, 153 solder balls arranged in a specific matrix, surface mount design suitable for reflow soldering automatic patch process.storage capacity8GB, to meet the storage requirements of lightweight embedded systems for operating systems, applications and configuration data.
Strictly follow the interfaceeMMC 5.1 industry standard, backward compatible with eMMC 5.0 and earlier specifications, using the MMC protocol for host communication.supportHS400 high speed mode, sequential reading speeds up to300MB/s, the highest sequential writing speed240MB/s.support1-bit, 4-bit and 8-bitProgrammable bus width, and SDR and DDR dual-mode operation.
The working voltage adopts a dual-rail power supply scheme: the core flash array power supply VCC is3.3V, the controller I/O power supply VCCQ is1.8V.Operating temperature range covered-20℃ to 85℃The consumer-grade wide temperature range meets the needs of most indoor electronic devices.
The chip has a built-in intelligent flash memory controller that comprehensively manages underlying operations such as interface protocols, bad block processing, ECC error correction, wear leveling, and garbage collection.It also supports advanced features such as Boot Partition, RPMB replay protection memory block, Secure Erase, Trim and FFU on-site firmware upgrade.
Core advantage: High integration makes small-size devices no longer a compromise
The value of BWCE28NH-08G in the design of compact smart devices is reflected inHigh integration + low power consumption + standardized interfaceon the combination.eMMC encapsulates NAND Flash and the controller together, and the main control terminal directly sends commands through the MMC protocol. The erase and write equalization, bad block management, ECC error correction, etc. of the underlying memory are all handled internally by the chip.R&D personnel do not need to deal with the complex timing control of NAND Flash, the development threshold is greatly reduced, and the product launch cycle is significantly shortened.
The compact package of 11.5×13.0mm is a standard size among similar eMMC products, and is particularly suitable for portable devices that have strict requirements on PCB area, such as smart watches and TWS headset charging cases.The standby current of less than 100μA further reduces the power consumption of the entire machine and provides longer battery life for battery-powered devices.
As a major domestic storage manufacturer, Baiwei's eMMC products have entered the supply chain systems of smart terminal manufacturers such as Huaqin Technology, Wingtech Technology, and Tianlong Mobile, and are widely used in terminal devices such as smartphones and tablets. The stability and consistency of the products have been verified by the market.
Typical application scenarios
The application landscape of BWCE28NH-08G covers multiple segments of consumer electronics and lightweight IoT.
Smart wearable devicesIt is its core application direction.Devices such as smart watches and smart bracelets need to store operating systems and applications in limited space. The 8GB capacity combined with the compact 11.5×13.0mm package provides sufficient storage space for wearable devices without occupying too much PCB area.
Smart home and smart speakersThis chip is also widely used.Smart speakers and smart central control screens need to store voice models and user configuration data. The reading speed of 300MB/s ensures the smoothness of system startup and voice interaction.
Tablets and learning machinesIt is the traditional application position of eMMC.Entry-level tablets and electronic learning devices use eMMC as the main storage unit, and their compatibility under operating systems such as Android and Linux is already very mature.
Network communication productsOn the other hand, it is used to store firmware and configuration files in network communication equipment such as routers and optical modems. The low power consumption feature helps reduce the overall energy consumption of the equipment during long-term operation.
Model meaning and selection expansion
The naming rules of Baiwei eMMC products have a clear logic.Model prefixBWCRepresents BIWIN eMMC product line,E28NHPoint to a specific product series and package specification,08GRepresents 8GB capacity.
Baiwei eMMC product line covers from4GB to 256GBfull capacity echelon.Backwards compatible models of the same seriesBWCTASC11P32GFor the 32GB version,BWCTASC21P64GFor the 64GB version,BWCTASC41P128GCorresponds to 128GB.If you need larger capacity storage, there are also other products in the same series.BWCTARV11X64G(64GB) and other models are available.
It is worth mentioning that Baiwei also providesUltra small size eMMC, the dimensions are only7.5mm×8.0mm×0.7mm, suitable for ultra-compact equipment with extreme requirements on PCB area.For applications that require industrial-grade wide temperature, Baiwei industrial-grade eMMC products support-40℃ to 85℃operating temperature range.
