The electronic tamper detection smart meter reference

design is a 3-ph electricity meter with MEMS tilt sensing

functionality that is used for physical tamper detection

The tilt sensing functionality is provided by Freescale’s

MMA8491Q MEMS tilt sensor

The 3-ph electricity meter is implemented on a single chip –

the Kinetis K30 Cortex-M4 core-based microcontroller

Includes MC1322x 802.15.4 compliant wireless node

based on Freescale’s third-generation

ZigBee® platform

Physically secure all elements of the smart grid, e.g., smart

meter, data concentrator, intelligent electronic devices

(IEDs), secure gateway

Energy efficient with Freescale’s lowest power tilt sensor

(400 nA per Hz) and the Kinetis K30 MCU using10 low-power

modes (2.1 micro amps typical for very low leakage at stop

mode 1) room temp @ 3 V
