Do you have any of these problems
when using eMMC or SD cards

NOR flash
is running out of capacity…
I'm worried about the reliability of MLC and TLC memory…
I am using an SD card, but vibration is causing it to not fit properly…
I need two memories, a boot memory and a log storage memory, but I don't have enough space or money…

Product capacity up to 16GB

The product capacity lineup ranges from 512MB to a maximum of 16GB.

Board-mounted SD card

This is a surface-mount type on-board storage with an SD card interface.
Since it is mounted, it has high resistance to vibration.
Uses SLC memory

Uses SLC memory

Uses 2D NAND SLC memory, which has a rewrite lifespan 10 times longer than eMMC, which is the mainstream MLC memory.
eSD allows booting and data storage on a single chip

eSD allows booting and data storage on a single chip

There may be cases where NOR type memory is used for boot memory and NAND type memory is used for log storage memory.
eSD allows boot and data storage on a single chip, which reduces space and costs.

Evaluation units can also be borrowed.

There may be cases where you can't know for sure without actually testing it.
We have a testing machine available, so please feel free to contact us.
Also, please contact us if you have any prior checks.

Features of eSD (embedded SD)

SD interface adopted

Embedded SD (eSD) with SD interface in BGA form factor

It can be used in the same way as a normal SD card, including command processing, making it a highly available device.
Ball pitch 1mm

Ball pitch 1mm

The pitch of the wiring between the pads makes it less likely to interfere with other components and does not require special processing.
Preparation of conversion tool for evaluation

Preparation of conversion tool for evaluation

We have prepared an SD/microSD conversion tool for evaluation purposes.
Supports lifespan diagnostic tools

Supports lifespan diagnostic tools

The internal status can be monitored. The information required to check the device status can be obtained.
SLC タイプNAND搭載

Equipped with SLC type NAND

Equipped with highly reliable SLC type NAND memory, it ensures long-term stable operation.
  • 43-bit/1KByte "ECC correction function" detects and corrects errors during data transfer
  • "Power interruption management function" prevents data corruption even in the event of a sudden power outage
  • "Static wear leveling" function that evens out the number of writes, including unused areas
  • "Read disturb management function" prevents malfunctions caused by excessive reading
  • RoHS compliant

Usage Scene

I want to achieve stable operation even in equipment that is subject to vibration.

I want to achieve stable operation even in equipment that is subject to vibration.

Before
We were using SD cards, but there were frequent connection failures due to fitting issues caused by device vibration.
After
By adopting eSD and mounting it on the board, connection failure caused by vibration has been eliminated. Furthermore, the product lifespan has been increased thanks to the highly reliable SLC memory!
I am using NOR flash but the capacity is insufficient

I am using NOR flash but the capacity is insufficient

Before
NOR flash was used as a boot device, but the capacity was insufficient for the next model to be updated.
After
The problem was solved by replacing it with a large-capacity eSD. It became possible to store data in the remaining capacity.
This means that one card can be used for both booting and data storage, reducing space and costs!

Flow of implementation

inquiry

Please let us know your requests.

Requirements hearing

We will check the details and suggest the most suitable product for you.　

Purchase evaluation unit/short-term rental

Please actually run it and check if there are any problems. If there are any additional elements you would like to add after it works, please let us know.

This introduction

We will order the required number of units and deliver them to you.

After-sales support

In the unlikely event of a problem occurring, we will support you with product analysis and countermeasures.
We will notify you in advance when the product will no longer be available for sale.

FAQ

Will it continue to be produced in the future?
SLC products are scheduled to be produced until 2028. We are also considering products using 3D-TLC NAND.
Can you evaluate it without implementing it?
We provide an SD conversion socket board that can be connected to the SD and microSD interfaces.
Since replacement is not possible during implementation, is it possible to know the product lifespan in advance?
By using the product in an actual way for a certain period of time, you can understand the expected lifespan.
It is compatible with the lifespan diagnostic tool "LiveMonitor", so you can monitor the product status in real time.
Can you provide a list of other specifications?
You can check it on the product page.
