OREANDA-NEWS. March 31, 2015. Toshiba Corporation (TOKYO: 6502) today announced the launch of a new microcontroller, “TMPM46BF10FG”, as the latest addition to its ARM® Cortex®-M4F-based TX04 series. The microcontroller is designed for secure communications control. Sample shipments start today with mass production scheduled to start in October 2015.

Users of secure communications control systems increasingly require mass memory data for firmware generation management, failure analysis and high-precision consecutive data storage, and such high-level security features as tamper detection and information concealment.

At the same time, they are also seeking to reduce the number of parts on system circuit board parts by using large capacity memory that incorporates multiple memory chips.

The new MCU incorporates a 514-KByte SRAM required for secure communications control, four types of security circuits for network communications, and an SLC NAND flash memory controller for memory expansion.

In addition, its clock independent watchdog timer operates to a built-in clock separate from the system clock, improving the safety of system function.

Toshiba is committed to developing new products that meet market demand and to expanding the new line-up of the TX04 series.
