Secure MCU for financial terminals

8 July 2009 DSP, Micros & Memory

Maxim’s new MAXQ1850 is a high-performance 32-bit RISC microcontroller for the financial terminal market. It integrates security supervisory features, advanced encryption acceleration, and 8 KB of non-volatile memory (NV SRAM) around a 32-bit MAXQ microcontroller core. The device’s security mechanisms protect against both logical and physical attacks: encryption engines are resistant to side-channel attacks and cryptanalysis; environmental sensors protect against physical manipulation; and secure tamper triggers offer many options for application-specific tamper-detection circuits. The MAXQ1850 provides an excellent cost point for use as a coprocessor in complex point-of-sale terminals or as the main microcontroller in encrypting PIN pad applications. It is also well suited for government applications and digital rights management.
