New microcontroller enables enhanced communication security and supports standard encryption protocols
Toshiba Electronics Europe has announced a new ARM® Cortex®-M4F based microcontroller for use in secure systems control. The TMPM46BF10FG expands Toshiba’s existing TX04 range and adds a selection of enhanced security features, ideally suited to applications in Internet of Things (IoT) devices, energy management systems, sensor technology and industrial equipment.
Users of secure communications control systems increasingly require mass memory data for firmware generation management, failure analysis and high-precision consecutive data storage. These requirements for high-level security features, such as tamper detection and information concealment, are met by the TMPM46BF10FG. The IC also meets the need to reduce the number of parts on system circuit board parts by supporting large capacity memory.
Based around an ARM Cortex-M4F core, with a maximum operating frequency of 120 MHz, the TMPM46BF10FG incorporates 1024 Kbyte of flash memory and 514 Kbyte SRAM required for secure communications control, four types of security circuits for network communications. The MCU also integrates an SLC NAND flash memory controller and 4- and 8-bit error correction circuitry (BCH ECC) that supports memory expansion with 1Gbit to 4Gbit SLC NAND flash memory chips.
To provide additional levels of safety, the IC includes a 16 channel interrupt input and a clock-independent watchdog timer, which operates separately from the system clock, improving the safety of system functions. In the case of a system clock malfunction, the watchdog timer is still capable of detecting errors.
