Toshiba launches one-chip microcontroller for electric energy calculation and communication used in smart meters

Toshiba Corporation (TOKYO: 6502) today announced the launch of a new one-chip microcontroller for a smart meter, "TMPM411F20XBG", as the latest addition to its line-up of TX04 series, the ARM® Cortex®-M4F core-based microcontrollers. Sample shipments start today.

A typical smart meter controller consists of an electricity calculation unit that measures current and voltage, a communication control unit that transmits and receives data with external equipment, and a display unit that outputs information to the display.

The new product incorporates two Cortex®-M4F cores to enable independent control of the measurement and communication units on one chip and reduce board space. In addition, security functions required for network communications—AES, SHA and ESG—are implemented. Tamper detection and interrupt detection at power failure are also implemented with super-low consumption power.

Toshiba is committed to developing microcontrollers that support and promote the widespread use of smart meters by electric utilities worldwide.
