Pass-through License for CRI Patented DPA Protection

Microchip has obtained a license from Cryptography Research, Inc. (CRI, now a division of Rambus) for the DPA patent portfolio, consisting of more than fifty patents. The pass-through licensing enables additional DPA-resistant high-speed cryptographic implementations in the FPGA fabric, if higher performance (or a different algorithm) is needed. Customers do not need to negotiate a separate license with Rambus if they need to incorporate DPA resistant functions in the PolarFire SoC FPGA MSS application or PolarFire FPGA fabric when purchasing “S” devices. For example, ordering code for a PolarFire MPF300T “S” device is MPF300TS-FSCG536I and for a non “S” device is MPF300T-FSCG536I. Ordering code for a PolarFire SoC FPGA MPFS250T “S” device is MPFS250TS-FCG1152 and for a non “S” device is MPFS250T-FCG1152.
