1. General Des ription
Apacer’s USB-Disk Module (UDM) is a high performance, embedded solid state drive (SSD) designed to
replace a conventional IDE hard disk drive. UDM SSD can be plugged into a standard Embedded USB
connector commonly found in desktops, portable PC systems and industrial PC systems. This product is
well suited for embedded flash storage applications offering new and expanded functionality as well as
more cost-effective designs, better performance and increased reliability.
1.1 Performance-optimized Controller
The heart of an UDM is the USB controller, which translates standard USB signals into the data and
controls of the flash media. This proprietary USB controller is specifically designed to attain high data
throughput from host to flash.
1.1.1 Power Mana ement Unit (PMU)
The power management unit (PMU) controls the power consumption of the UDM. It can dramatically
extend product battery life by leaving the idle part of the circuitry into sleep mode. The PMU has zero
wake-up latency.
1.1.2 SRAM Buffer
The SRAM buffer is a key contributor to the USB controller performance. It optimizes data writes to the
flash.
1.1.3 Error Correction Code (ECC)
The UDM uses BCH Error Detection Code (EDC) and Error Correction Code (ECC) algorithms which
correct up to four random single-bit errors for each 512-byte block of data. High performance is achieved
through hardware-based error detection and correction.
1.1.4 Wear-Levelin
Flash memory can be erased a limited number of times, This number is called the erase cycle limit, or
write endurance limit, The erase cycle limit applies to each individual erase block in the flash device.
In a typical application, and especially if a file system is used, specific pages are constantly updated (e.g.,
the page that contains the FAT, registry, etc.). Without any special handling, these pages would wear out
more rapidly than other pages, reducing the lifetime of the entire flash.
To overcome this inherent deficiency, Apacer’s USB-Disk Module (UDM) uses wear-leveling algorithm.
This wear-leveling algorithm ensures that consecutive writes of a specific sector are not written physically
to the same page in the flash. This spreads flash media usage evenly across all pages, thereby
maximizing flash lifetime.
The wear-leveling mechanism provides more than 100,000 write/erase cycles for reliable data storage
over an extended period.
1.1.5 Write Protection Mode (Optional)
When the device is configured to the Write-Protection mode, it enhances the data security and protection.
This feature prevents the stored data from inadvertent system writes or erases, and viruses.
