LPRS, Europe's leading manufacturer of short-range
wireless devices, now offers Internet of Things (IoT) system
builders with a system-on-chip fully integrated wireless controller
suitable for remote, battery powered sensor systems, which can
offer current consumption as low as 32µA
The low cost, high security easyRadio Integrated Controller
(eRIC) offers designers seven power saving modes of operation to
ensure maximum battery life of remote sensors. The LPRS eRIC
transceiver power saving modes provide control of the duty cycle of
the receiver so that the 'ON' time can be set to 12.5%, 6.25%, 3.1%
, 1.56%, 0.78%, 0.39% & 0.2% with corresponding levels of power
saving from its "always on" current of 16mA. The transmitter
may then be independently set to the same duty cycle as the
receiver or longer as required for transfer of data. Up to 250Byte
data-packets are supported throughout all operating modes and up to
500Kbs over air data rates are available.
The LPRS eRIC (easyRadio Integrated Controller) module is now
available with operating frequencies for World Markets and provides
secure over-air transmission with the availability of an AES 128
bit data encryption option. Many other advanced features are
available as standard including; received signal strength indicator
(RSSI), carrier detect and group ID.
The advanced design of this transceiver uses system on chip
(SOC) technology removing the need for an external processor. The
on-board processor memory is partitioned giving half to the
easyRadio configurable settings and communication software and
leaving the rest available for design engineers to add their own
application code. Code can be written using industry standard tools
and a quick to learn API (application programming interface). This
partitioned memory design will often eliminate the need for any
additional microcontroller, saving cost, space and power.
eRIC is an exceptional value RF transceiver intended for
embedded high-volume applications in the "Smart" or "IoT" arena
including; building and lighting control, security, home monitoring
and medical products, vehicle and contents monitoring, renewable
energy control and remote sensor systems. eRIC has been designed to
simplify end product manufacture and is packaged for SMD assembly
and measures just 20x15x5mm
eRIC continues to use the popular and simple to use easyRadio
programming protocols, operates in the ISM frequency bands (Europe
433 and 868MHz, USA 915MHz), meets ETSI and FCC requirements, has
pin interface compatibility with existing easyRadio Advance (eRA)
products, has a simple to use and customer configurable and
programmable I/O interface and has a built-in temperature
sensor.
Barry Gillibrand, Managing Director of LPRS, comments, "Many
industrial monitoring systems and possible IoT applications will
employ sensors in remote and difficult to access locations.
Ensuring maximum operating life of battery powered devices is a key
criterion for design engineers and eRIC provides a flexible
solution with maximum convenience. Our many years of experience of
supplying easyRadio wireless modules has provided us with
real-world experience of our customer's requirements and eRIC
provides a complete solution for high-volume wireless control and
communication markets. Continuing to use our very successful
easyRadio interface ensures our existing customers a smooth
transition and gives new customers the ability to configure
operating frequency, bandwidth, output power, and data-rate
enabling a developer to avoid local interference from nearby
devices
In addition to designing and manufacturing the highly successful
eRIC and easyRadio Advanced (eRA) wireless modules in the UK, the
full LPRS product range now includes; Raspberry Pi and Arduino
Shield wireless platforms, antennas, wireless key fobs, a wide
range of sensor products and the IQRF range of wireless mesh
networking components for telemetry, industrial control and
building automation.
