5.1 Physical Interface

[Signal]

[I/O]

[Description]

CS0-

I

Chip select signal decoded from the host address bus. This signal

 

 

is used by the host to select the command block registers.

CS1-

I

Chip select signal decoded from the host address bus. This signal

 

 

is used by the host to select the control block registers.

DA 0-2

I

Binary decoded address signals asserted by the host to access task

 

 

file registers.

KEY

-

Key pin for prevention of erroneous connector insertion

PDIAG-

I/O

This signal is an input mode for the master device and an output

 

 

mode for the slave device in a daisy chain configuration. This

 

 

signal indicates that the slave device has been completed self-

 

 

diagnostics.

 

 

This signal is pulled up to +5 V through 10 kΩ resistor at each

 

 

device.

CBLID-

I/O

This signal is used to detect the type of cable installed in the

 

 

system.

 

 

This signal is pulled up to +5 V through 10 kΩ resistor at each

 

 

device.

DASP-

I/O

This is a time-multiplexed signal that indicates that the device is

 

 

active and a slave device is present.

 

 

This signal is pulled up to +5 V through 10 kΩ resistor at each

 

 

device.

IORDY

O

This signal requests the host system to delay the transfer cycle

 

 

when the device is not ready to respond to a data transfer request

 

 

from the host system.

DDMARDY-

O

Flow control signal for Ultra DMA data Out transfer (WRITE

 

 

DMA command). This signal is asserted by the device to inform

 

 

the host that the device is ready to receive the Ultra DMA data Out

 

 

transfer. The device can negate the DDMARDY- signal to

 

 

suspend the Ultra DMA data Out transfer.

DSTROBE

O

Data In Strobe signal from the device during Ultra DMA data In

 

 

transfer. Both the rising and falling edges of the DSTROBE signal

 

 

latch data from Data 15-0 into the host. The device can suspend

 

 

the inversion of the DSTROBE signal to suspend the Ultra DMA

 

 

data In transfer.

CSEL

I

This signal to configure the device as a master or a slave device.

 

 

When CSEL signal is grounded, the IDD is a master device.

 

 

When CSEL signal is open, the IDD is a slave device.

 

 

This signal is pulled up with 240 kΩ resistor at each device.

DMACK-

I

The host system asserts this signal as a response that the host

 

 

system receives data or to indicate that data is valid.

MHW2060AC, MHW2040AC specifications

The Fujitsu MHW2040AC and MHW2060AC are notable hard disk drives (HDDs) that have been widely used in various computing applications, especially in laptops and compact devices. These models are part of Fujitsu's commitment to providing reliable storage solutions that meet the demands of modern computing.

The MHW2040AC offers a storage capacity of 40 GB, while the MHW2060AC provides a slightly larger capacity at 60 GB. This range of storage makes both models suitable for users looking for dependable space for documents, multimedia files, and software applications. Both drives utilize a 2.5-inch form factor, ideal for mobile computing, as they are lightweight and designed to fit into space-constrained environments.

In terms of performance, both drives operate at a spindle speed of 5400 RPM. This speed strikes a balance between power consumption and performance, making these drives an efficient choice for everyday tasks, such as web browsing and office applications. The drives are equipped with an interface of Ultra ATA/133, which enables faster data transfer rates compared to older models, thereby enhancing overall system responsiveness.

The MHW2040AC and MHW2060AC also incorporate several advanced technologies to bolster their performance and reliability. One such feature is the use of a fluid dynamic bearing (FDB) for the spindle motor, which minimizes noise and vibration, thus improving the overall user experience. Additionally, both drives come with error correction technology that helps maintain data integrity by detecting and correcting errors during read and write operations.

Moreover, these HDDs feature a shock sensor that can detect sudden movements, allowing the drive to park its heads to prevent data loss and hardware damage. This is particularly beneficial in mobile environments where the risks of impact are higher.

Both the MHW2040AC and MHW2060AC are designed with energy-saving features, making them an environmentally responsible choice for energy-conscious consumers. Their low power consumption not only contributes to a reduced carbon footprint but also extends battery life for portable devices.

In summary, the Fujitsu MHW2040AC and MHW2060AC are reliable, efficient, and user-friendly hard disk drives that combine moderate capacities with advanced features designed to enhance performance, ensure data integrity, and extend device longevity. These drives are well-suited for a range of applications, making them a solid choice for users seeking dependable storage solutions.
