ESI-TRX401 wireless transceiver radio
IP for ISM band of 400-960 MHz
Ensphere Solutions has made available its new ESI-TRX401
wireless transceiver radio intellectual property (IP) for
ISM band (400-960 MHz). The core has been implemented using
TSMC's 180nm CMOS process and the IP is an ideal radio for
Application Specific Integrated Circuits (ASICs) and Application
Specific Standard Products (ASSPs) needing wireless connectivity.
Smart meters, building automation, remote keyless entry,
and sensor mesh networks are among key applications that
can be served well by this IP.
The following are some of the key performance parameters
of this core:
Sensitivity: -110 dBm
Output Power Range: -8.0 to +15 dBm
Ultra Low Power Consumption: 16 mA @ receive
13 mA @ 0 dBm transmit power
31 mA @ 13 dBm transmit power
Data Rate: 0.397 - 200 kbps
Modulation: FSK/GFSK
Ensphere will make this technology available to its customers
in one of two possible ways. Ensphere will offer this core
as a standalone IP for integration in devices being developed
by its customers. Alternatively, ESI offers design services
for developing custom chips based on ESI-TRX401. Ensphere
has access to an extensive library of internal and external
IPs that can be integrated alongside to this core.
"Supporting some type of wireless connectivity in
newer ASICs and ASSPs has become a hard requirement and
is no longer an optional nicety," said Hessam Mohajeri
Ensphere's Chief Executive Officer. "Introduction of
ESI-TRX401 is a significant milestone for Ensphere, our
goal is to offer a mature and conformant ISM radio core
allowing our customers to focus on other aspects of their
program."
"We have chosen a very mature and popular process
technology to implement this IP," said Al Gharakhanian,
Vice President of Marketing. "Our challenge has been
to strike a balance between process maturity, wafer pricing,
and non-recurring expenses associated with developing an
analog-intensive ASIC targeting high volume applications."
