Semtech, a supplier of analogue and mixed-signal semiconductors, has introduced the SX1212 UHF transceiver and SX1213 UHF receiver, two new devices in the company’s RF products platform.
The SX1212 is a single-chip transceiver that operates in the 300MHz to 510MHz frequency range with a receive current of only 2.5mA. The SX1213 is a single-chip receiver for the same frequency range and with the same low receive current level. Both devices are designed for wireless alarm, security, sensors network in home automation and automated metre reading applications, the company said.
The new devices are said to complement the SX1211, a transceiver that operates in the 863-960MHz frequency range and features a receive current of less than 3.0mA. All of the products are pin compatible.
The new offerings reportedly deliver a consistent RF range as the battery voltage decreases over time. For outdoor applications in extreme conditions, both devices leverage the company’s technology to deliver stable RF performance across a -40ºC to +85ºC temperature range.
Both devices incorporate a baseband modem with data rates up to 200Kbit/s. Data handling features include a sixty-four byte FIFO, packet handling, automatic CRC generation and data whitening. All RF communication parameters are expected to be programmable and most of them may be set, the company stated.
Marc Pégulu, industrial analog product line manager at Semtech, said: “The low receive current of the SX1212 and SX1213 removes a limiting factor to innovation in the wireless control industry, which we think will lead to breakthrough systems that make use of a high receiver on time.
“For example, next generation energy harvesting solutions can leverage these devices in motion detectors and wireless remote controls to provide improved lighting smart controls that can optimise light levels for a perfect balance of energy consumption and productivity.”
In addition, with support for both frequency-shift keying (FSK) modulation and on-off keying (OOK) modulation, the new offerings can be used in new and legacy sensor network designs. The devices support FSK data rates from 1.56 to 200Kbit/s and OOK data rates up to 32Kbit/s.
