1. General Description

Apacer’s ATA-Disk Module (ADM) is a high-performance, embedded flash drive designed to replace the

conventional IDE hard disk drive. The ADMs can be plugged into a standard IDE connector commonly

found in desktops, IT-STB, industrial PCs and thin client systems. Apacer’s ADM SSD has a built-in

microcontroller with file management firmware that communicates with the ATA standard interfaces. This

means the ADM does not require any additional or proprietary host software such as the Flash File

System (FFS) and the Memory Technology Driver (MTD).

This product is well suited for embedded flash storage applications by offering new and expanded

functionalities as well as more cost-effective designs, better performance and increased reliability.

ADM is designed to work at either 5 or 3.3 Volts, supports the standard ATA/IDE protocol for up to PIO

Mode-4, Multiword DMA Mode-2 and Ultra DMA Mode-4 interfaces, and uses the standard ATA driver

complying with all major operating systems such as Microsoft Windows series, Apple Mac OS family, and

UNIX variants.

1.1 Performance-Optimized Controller

The kernel of an ATA-Disk Module is the ATA controller, which translates standard ATA signals into the

data and controls of the flash media. This proprietary ATA controller is 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 the ATA-Disk Module. It reduces

the power consumption of the ATA-Disk Module Controller by putting circuitry not in operation into sleep

mode. The PMU has zero wake-up latency.

1.1.2 SRAM Buffer

The ATA-Disk Module Controller performs as an SRAM buffer to optimize the host’s data transfer to and

from the flash media.
