SATA-Disk Module 4
APSDMxxxxX5AN-AXXX
1. General Description
Apacer’s SATA-Disk Module 4 (SDM4) is a high-performance, embedded SSD designed to replace the
conventional SATA hard disk drive. SDM SSD can be plugged into a standard Serial ATA 7-pin connector
commonly found in desktops, IT-STB, industrial PC and thin client systems. Moreover, Apacer provides
an innovative way for design-in customers to strengthen the vibration-resistance between SDM4 and
mainboard.
Apacer’s SDM4 has a built-in microcontroller with file management firmware that communicates with
SATA standard interface. This means SDM4 does not require additional or proprietary host software such
as Flash File System (FFS) and Memory Technology Driver (MTD). This product is well suited for
embedded flash storage applications offering new and expanded functionalities as well as more cost-
effective designs, better performance and increased reliability.
SDM4 Series is designed to work at 5 Volts and uses a standard SATA driver that complies with major
operating systems such as Microsoft’s Windows series.
Featuring technologies as Apacer-specific Wear-leveling algorithms, S.M.A.R.T, Enhanced Data Integrity,
Intelligent Power Failure Management, ATA Secure Erase, and TRIM, Apacer assures users of a versatile
device on data storage.
1.1 Performance-Optimized Controller
The heart of SDM4 is the Flash controller, which translates standard SATA signals into the data and
controls of the flash media. The SATA and Flash Management controller are specifically designed to
attain high data throughput from the host to the flash.
1.1.1 Power Management Unit (PMU)
The power management unit (PMU) controls the power consumption of SDM4. 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 Flash Controller performs as a SRAM buffer to optimize the host’s data transfer to and from the flash
media.
