ARM-Based MCU Reduces Encryption/Decryption Time For IC Card Terminals

Oki Semiconductor is now offering an application-specific ARM-based microcontroller that integrates all functions needed by IC card terminals into a single chip.

The ML675050 is a single-chip, 32-bit general-purpose microcontroller based on the ARM7TDMI core. It was developed with uPLAT-7D, Oki's system LSI integrated development platform.

The chip is equipped with a Modulo Calculation Accelerator, which natively supports encryption/decryption, and is geared toward applications with built-in network IC card reader/writers that require secure transactions. It also offer a USB 2.0 full-speed host controller and device controller. It features battery back-up RAM for storing crypto-key data, which contains a separate power supply terminal.

Samples are available now, with volume production scheduled for June 2006.
