Interface

[signal]

[I/O]

 

[Description]

ENCSEL

I

This signal is used to set master/slave using the CSEL signal (pin 28).

 

 

Pins B and D Open: Sets master/slave using the CSEL signal

 

 

 

is disabled.

 

 

 

Short: Sets master/slave using the CSEL signal

 

 

 

is enabled.

MSTR-

I

MSTR, I, Master/slave setting

 

 

Pin A, B, C, D open: Master setting

 

 

Pin A, B Short:

Slave setting

RESET-

I

Reset signal from the host. This signal is low active and is

 

 

asserted for a minimum of 25 ∝ s during power on.

DATA 0-15

I/O

Sixteen-bit bi-directional data bus between the host and the

 

 

device. These signals are used for data transfer

DIOW-

I

Signal asserted by the host to write to the device register or data

 

 

port.

 

STOP

I

DIOW- must be negated by the host before starting the Ultra

 

 

DMA transfer. The STOP signal must be negated by the host

 

 

before data is transferred during the Ultra DMA transfer. During

 

 

data transfer in Ultra DMA mode, the assertion of the STOP

 

 

signal asserted by the host later indicates that the transfer has been

 

 

suspended.

 

DIOR-

I

Read strobe signal from the host to read the device register or data

 

 

port

 

HDMARDY-

I

Flow control signal for Ultra DMA data In transfer (READ DMA

 

 

command). This signal is asserted by the host to inform the

 

 

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

 

 

transfer. The host can negate the HDMARDY- signal to suspend

 

 

the Ultra DMA data In transfer.

HSTROBE

I

Data Out Strobe signal from the host during Ultra DMA data Out

 

 

transfer (WRITE DMA command). Both the rising and falling

 

 

edges of the HSTROBE signal latch data from Data 15-0 into the

 

 

device. The host can suspend the inversion of the HSTROBE

 

 

signal to suspend the Ultra DMA data Out transfer.

INTRQ

O

Interrupt signal to the host.

 

 

This signal is negated in the following cases:

−

−

−

−

−

assertion of RESET- signal

Reset by SRST of the Device Control register Write to the command register by the host Read of the status register by the host Completion of sector data transfer (without reading the Status register)

The signal output line has a high impedance when no devices are selected or interruption is disabled.

One of its primary features is the advanced cache memory architecture, which allows for quicker access to frequently used data. This enhances overall system performance while preserving energy consumption.

The MHL2300AT provides a step up, with its 300GB of capacity. It also maintains a 5400 RPM speed and is designed for optimal heat dissipation and durability. This model is particularly suited for mobile computing applications due to its lightweight design and low power requirements. The MHL2300AT also integrates a sophisticated error correction code (ECC) technology, enhancing data integrity during storage and retrieval processes.

Moving on to the MHM200AT, this unit provides substantial storage of 200GB, maintaining a similar 5400 RPM speed. What sets the MHM200AT apart is its focus on data security with Built-in Security Features such as disk encryption capabilities. This model is suitable for professionals dealing with sensitive information, ensuring both performance and protection against data breaches.

Lastly, the MHM215OAT, another key model, balances user-friendly design with performance metrics. It offers a generous 150GB capacity and features an enhanced seek time for quick file access. With its emphasis on reliability, the MHM215OAT is often utilized in environments where uptime is critical, such as in commercial servers or high-performance workstations.

In conclusion, Fujitsu's MHM2100AT, MHL2300AT, MHM200AT, and MHM215OAT each possess unique features and technologies that cater to diverse user needs. Their combination of efficient power consumption, enhanced data integrity, and reliability make them compelling choices for businesses and individuals alike.
