Hitachi mu-Chip : World’s Smallest Wireless RFID Chip
22
March
Hitachi created the world’s smallest RFID chip, the (µ-chip) mu-chip which measures 0.4mm² which is also wireless, batteryless uses an external antenna to receive and trasmit 128 bit signals to receivers nearby. Read more about the usage and how this chip would shape the world beyond tomorrow.
1. What is mu-chip (RFID: Radio Frequency IDentification)?
Hitachi’s super-mini wireless automatic recognition Integrated Circuit (IC) chip (mu-Chip) is only 0.4 mm squared. This downsizing was achieved through a change in approach by regarding the IC as a “point” instead of a “face”. As a result, it has become possible to attach our RFID tags (mu-Chips) to various materials and parts, including paper, in a manner unthinkable in the case of conventional RFID tags.
Mu-Chip Specifications:
- Dimensions of 0.4mm squared
- 128-bit ROM (Read Only Memory) capacity
- 2.45 GHz frequency
- Read range of up to 30 cm
- Passive tag (no battery required)
Conceptual drawing
The mu-chip is actually protected by synthetic resin on the back of the external antenna.
High security
The ID data of all mu-Chip is unique and cannot be rewritten, its security is ensured. Furthermore, custom codes can be installed. ID management can be geared to the characteristics of each product.
Micro size
Owing to the fact that the mu-chip is 0.4mm squared, it can be packaged into paper, parts, and other media and equipment in an approach previously considered difficult.
Secure ID management
Every level of unique ID, reader equipment, and applied systems is supported by the security management unique to mu-Chip.
Environmentally friendly
The management of recycled parts and materials by means of custom and unique codes will enable the efficient recovery and reuse of resources.
