London—Radiometrix has just
introduced the CTA88 remote control chip application board that provides simple
8-channel digital I/O implementations of
remote control functions, using either the company’s multichannel LMT/LMR (UHF
and VHF band) or single frequency BiM (FM band) wireless radio modules.
The CTA88 chip is an 8 bit address
encoder/decoder for use with license-exempt ISM/SRD band radio modules. It
allows a one-way wireless link set-up for remote control applications,
requiring minimum engineering effort. The TX and RX application boards are designed to easily evaluate the
CTA88 device in simple applications.
The boards consist of the following:
Two CTA88-000-DIL chips
CTA88 encoder board
CTA88 decoder board
¼ wavelength monopole or helical antennas
4 jumpers for mode configuration
DIP switches for address and frequency channel
8 opto-isolated digital inputs
8 relay outputs
The boards measure 115-mm x 86-mm x
20-mm with an operating temperature range of -20ºC
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
