Toshiba intros all-in-one smart meter MCU

Toshiba Electronics is targeting smart metering designs with a ARM Cortex-M4F core-based microcontroller for making electric power calculation in meters, but which will also manage comms and display functions.

The TMPM411F20XBG MCU also implements tamper detection and failure detection along with key security functions suitable for secure network communications. These include Advanced Encryption Standard (AES), Secure Hash Algorithm (SHA) and Entropy Source Generator (ESG).

The TMPM411F20XBG operates at 2.7 to 3.6V, with a maximum operating frequency of 80MHz.

It has an internal memory of 2048kbyte flash and 290kbyte total SRAM, 34-channel direct memory access (DMA), 9-channel 12-bit analogue-to-digital converter (ADC).

The product is available in 14x14mm VFGBA193 package.
