ML675050 - ARM-Based Microcontroller Reduces En-/Decryption
Time for IC Card Terminals

ARM®-based ML675050 microcontroller, an application specific LSI (ASSP) that integrates all functions necessary in IC card terminals into a single chip. The chip is equipped with a Modulo Calculation Accelerator necessary in RSA cryptography, and significantly reduces the encryption/decryption time compared to the conventional method using software.

Oki's ML675050 is a single chip 32-bit general-purpose microcontroller using ARM7TDMI® as a core, and was developed based on μPLAT®-7D, Oki's system LSI integrated development platform. By combing the chip with a 8KB cache memory, the ML675050 achieves a high performance. The chip can also be used in portable payment terminals that require battery drives because the chip includes abundant methods for power saving, effectively controlling power according to the usage.

With the following features listed below, designers can reduce their total cost using Oki's ML675050 MCU:

Equipped with Modulo Calculation Accelerator required for RSA encryption
- the accelerator enables high-speed encryption, reducing the RSA encryption time from 14ms to 0.6ms for a 1024bit key compared to Oki's software-based encryption using Oki's ARM9 MCU (120MHz) RSA decryption time is also reduced from 267ms to 20ms under the same conditions
- the ML675050 also includes battery back-up RAM for storing crypto-key data, which contains a separated power supply terminal. When the ML675050 is separated from PCB, the stored crypto-key date will disappear
A comprehensive set of peripherals integrates functions for IC card terminals into a single chip
- equipped with USB2.0 full-speed host controller and device controller, Oki's ML675050 is the only MCU product that achieves connectivity with host systems and connects with USB devices such as bar code readers
- it integrates all the functions necessary for IC card terminals into a single chip by combining peripheral functions including Monochrome QVGA LCD controllers and I²C controllers
