BIRMINGHAM, England, May 25, 2011 -

- The industry's first ever ZigBee(R) Smart Energy compliant module to
combine three key features: lower power, faster deployment and trouble-free
compliance with wireless standards

ByteSnap Design Ltd, (www.bytesnap.co.uk), a specialist in
innovative embedded hardware and software design, announces the release of
the ZMM-01, the industry's first ever ZigBee Smart Energy module
(bytesnap.co.uk/products-zigbee-modules/) to combine the key features
of metering and control in a single, low power platform. The ZMM-01 also
provides a Real Time Clock, accurate up to 2ppm.

By implementing the ZigBee Smart Energy protocol, the ZMM-01 is able to
use the command-set specified by the standard to control energy equipment
within the home or office. Wirelessly connecting to other devices through the
ZigBee mesh network, the ZMM-01 forms a fundamental part of the smart home,
helping to lower power usage by implementing building management protocols.

The ZMM-01 is well suited to many types of distributed control and
monitoring systems, for example: wireless charging for electric vehicles,
street lighting control, data centre power monitoring and building
air-conditioning control.

The key to the ZMM-01's comprehensive capabilities is ByteSnap Design's
expertise in combining hardware and software design to develop low power
devices. The module is based on the market-leading Ember EM357; a ZigBee
radio-on-a-chip which integrates a fully compliant IEEE 802.15.4/ZigBee
wireless transceiver with the powerful ARM Cortex-M3 microcontroller, able to
run the ZigBee Smart Energy protocol and application code while still
consuming just 30mA to transmit.

Closely coupled to this is the Cirrus Logic CS5467 Analogue Front End
(AFE); developed specifically for energy measurement applications. The AFE
incorporates on-chip functions for measuring voltage and current to calculate
active, reactive and apparent power/energy with Energy Linearity: plus or
minus0.1% of Reading over 1000:1 Dynamic Range.

The ZMM-01 simplifies working with ZigBee Smart Energy - implementing a
complete ZigBee SE smart meter now only requires the addition of a shunt
resistor and current transformer (CT). The resulting device can form the
heart of a meter that meets IEC EN62053-21 class 1 or 62053-23 class 2.

The ZMM-01 offers a Smart Energy solution that is ready for system
integration. The ZDM-01 Development Kit complements the ZMM-01 Smart Energy
module, providing a complete platform for module evaluation and code

Dunstan Power, Director, ByteSnap Design, commented: "Energy management
is expected to help drive the M2M market into the mainstream over the next
two years. Legislation is being implemented across Europe and other regions,
creating demand for solutions in this emerging market. The ZMM-01 offers OEMs
and ODMs the opportunity to accelerate their entry in to this fast-moving
marketplace with a pre-certified and fully compliant turn-key solution."
