B-series (ROM-less, new e-Flash Technology)
As a successor of A-series, most of the advantages of A-series can be found in this newly developed smart card chip family.
As the requirement of non-volatile-memory is increasing, advanced embedded FLASH technology is used in B-series to optimize the cost to memory size ratio. The write and erase time is also greatly improved compare with A-series products.
Similar to other Microtech Innovation’s ROM-less products, no ROM mask making is required for B-series. The card operating system (COS) can be loaded into the chip just before it is issued to the field. Memory Management Unit (MMU) with firewall technology and new security features allow multiple applications can be implemented on the same chip without compromise of security. Key features of B-series are highlighted below:
- New embedded FLASH technology for better performance
- Flexible – NVM can be partition into program or data by user with overwrite protection
- Short cycle time β no ROM mask is needed
- High speed operation to shorter the personalization time
- Long battery life β low power GSM mode
- Memory Management Unit with firewall – support supervisor mode and user mode for multiple application environment
- Security features to minimize the risks of unauthorized access to data inside the card
