Toshiba, Japanese technology company ,has announced the launch of 
new ARM Cortex-M4F based microcontroller for use in secure systems control.
The new TMPM46BF10FG incorporates a true random number generator (TRNG: SP800-90C standard) through a random entropy seed generation (ESG) circuit and Hash-DRGB created by the secure hash processor (SHA) and software program. It is intended for IoT devices, energy management systems, sensors 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, and such high-level security features as tamper detection high-level security features and information concealment.
“This meets the standards of security that are required in network communications. 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,” said Toshiba.
Maximum operating frequency is 120MHz and there is 1Mbyte of flash memory, 514kbyte of RAM and an SLC NAND flash controller and 4 and 8bit error correction that supports 1-4Gbit flash chips. There is a 16 channel interrupt input, clock-independent watchdog timer, 32 channel direct memory access, 12bit ADC (8 channel), 16bit timer (8 channel), SPP (3 channel), SIO/UART (4 channel) and full UART (2 channel) I2C (3 channel).
