Thông số kỹ thuật
This is a 32GB industrial-grade eMMC 5.1 embedded flash memory chip developed by Yangtze Memory Technologies, integrating NAND flash storage and dedicated master control management controller inside a single package, which serves as local persistent storage for embedded main control equipment without external peripheral storage management circuits.
Part Number Definition
YMEC stands for the standard eMMC storage product series under the brand. The digit 6 corresponds to 32GB effective user capacity, A2TB defines 153-ball FBGA packaging and HS400 high-speed transmission mode, the following suffix codes represent die stacking mode, firmware version and factory production specification configuration.
Core Electrical and Functional Parameters
Fully complies with JEDEC JESD84-B51 eMMC 5.1 formal protocol standard, supports 8-line HS400 high-speed working mode, maximum sequential read speed reaches 400MB/s and sequential write speed hits 200MB/s, with stable random read and write performance to adapt to system boot, log recording and file storage demands. Built-in complete wear leveling, bad block automatic management, power failure data protection and ECC error correction mechanism, which greatly reduces the probability of data loss and storage chip damage under unstable power supply and long-term repeated erasing and writing conditions. Core power supply voltage ranges from 2.7V to 3.6V, IO interface working voltage is 1.7V to 1.95V, perfectly matching ARM embedded processors and industrial mainboard level standards. It supports hardware reset pin and system sleep power-saving mode to lower idle power consumption of the whole equipment. The chip adopts single-die TLC flash particle architecture, with standard erasing and writing life meeting the long-term operation requirements of unattended industrial equipment.
Packaging and Assembly Specifications
Adopts 153-pin FBGA ball grid array packaging, overall dimension 11mm×13mm, ball pitch 0.8mm. It belongs to moisture sensitive level MSL3 component, and reflow soldering operation must be finished within 168 hours after opening the original vacuum packaging. Tray bulk packaging is adopted for factory automated SMT mounting, and X-ray inspection is required to confirm soldering integrity after welding. The pin definition is fully compatible with mainstream foreign brand same-specification eMMC chips, enabling direct pin-to-pin replacement and hardware compatibility without modifying PCB layout.
Environmental and Compliance Standards
Continuous working temperature range covers -40℃ to +85℃, which can run stably in cabinet industrial control, vehicle-mounted equipment and outdoor monitoring terminals with large temperature fluctuation. The product follows lead-free production process and meets international environmental material restriction standards. Domestic supply chain ensures stable stock and shorter delivery cycle compared with imported storage chips.
