THine Electronics, Inc. has unveiled two new serial transceivers that enable industrial machines, drones, electric vehicles, robots and consumer electronics systems to handle newly established sensing requirements. The THCS253 and THCS254 transceivers are called industry-first unique LSI products that can serialize different types of signals and allow users to add sensors functions by only changing the registers’ settings instead of extensive redesigns.

The transceivers enable systems with many peripheral sensors to simplify cabling for sensor and control functions, translating into system cost, size and weight savings. They also allow future expansion with additional features on the same platform systems with minimal redesign efforts or the use of FPGAs that require time-consuming redesigns, said THine.
As an example, the THCS253 can serialize sensing signals using 32 GPIO interfaces into two differential signals, reducing the number of cables and connectors by up to 88%. They not only lower noise emission inherent with the use of cables but also improve productivity in manufacturing processes by simplifying assemblies.
Given their ability to reshape waveforms in the receiving circuit, the transceivers can transmit data for long distances of 10 meters instead of approximately 1 meter for greater flexibility in the layout of manufacturing sites or warehouses, said the company.
Key features include support for up to 32-bit GPIOs, full duplex communications by two pairs of differential signals, support for up to 8-bit low-speed GPIO in standby mode with low power of 6 mA, an adaptive equalizer for high-loss transmission media, 8B10B encoding/decoding and error detection and notification. In addition, the transceivers feature I/O expansion via conversion from a two-wire serial interface to a parallel GPIO and digital noise filters that can be set for input and output.

Key specs include power supply operation from 1.7 V to 3.6 V, a wide IO voltage range from 1.7 V to 3.6 V and an external reference clock frequency of 9 MHz to 133.3 MHz. The operating ambient temperature range is -40°C to 85°C. The THCS253 and THCS254 are available in QFN64 (9 × 9 mm) and QFN48 (7 × 7 mm) packages, respectively.
