Secure Microcontroller Offers Low Pin Count and Small Footprint for Financial Terminal Applications
Maxim has introduced the MAXQ1850, a high-performance 32-bit RISC microcontroller for the financial terminal market. The MAXQ1850 integrates security supervisory features, advanced encryption acceleration, and 8KB of nonvolatile memory (NV SRAM) around a 32-bit MAXQ microcontroller core. The microcontroller also has the lowest pin count and smallest footprint available for applications that require a high level of physical and logical security.
It pThe MAXQ1850'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. Most important for secret key protection is the MAXQ1850's custom-designed, battery-backed nonvolatile NV SRAM--the best kind of memory for secret storage because it can be erased quickly in reaction to tampering.
The MAXQ1850's combination of NV SRAM for secret storage, tamper-detection technology, and hardware encryption accelerators make it the best choice for financial terminal applications and any other application requiring security certifications such as PCI, FIPS 140-2, or Common Criteria.
