Toshiba has MCU for smart meter applications

Toshiba has added to its TX04 series of ARM Cortex-M4F core-based microcontrollers.

The TMPM411F20XBG facilitates electric power calculation and communication in smart meters, as well as sensing and communications in other measurement devices. By integrating multiple functionalities, the TMPM411F20XBG achieves independent control of the electric power calculation and communication control in a single chip, reducing the circuit board area within the smart meter. The device also implements tamper detection and failure detection, as well as key security functions suitable for secure network communication. These include Advanced Encryption Standard (AES), Secure Hash Algorithm (SHA) and Entropy Source Generator (ESG). The TMPM411F20XBG operates from 2.7 to 3.6V, with a maximum operating frequency of 80MHz. It has an internal memory of 2048 Kbytes Flash and 290 Kbytes total SRAM, 34-channel direct memory access (DMA), 9-channel 12bit A/D converter. It is available in a 14 x 14mm VFGBA193 package.
