THCS132_Rev.1.01_E THCS132 I/OSpreader General Description Features The THCS132 provides a function to serialize multiple parallel signals into single-ended serial line at least or to deserialize the data stream over single-ended serial line or single differential pair into multiple parallel signals. This small number of transmission line simplifies system configuration and reduces system cost including cable width, connector size and pins and PCB layout area. The THCS132 is offered in 8bit/16bit parallel IOs as host MPU interface. It can transfer 16bit independent parallel signals to remote side by only 1-line or 1-pair cable. Also, the THCS132 set as master device can control plural slave devices by transmitting and receiving data that is designated as a device address. Transmitter, receiver or transceiver function can be selected by pin options. - No External Clock Required. -8bit/16bit Parallel IOs to MPU. - Uni-directional/Bi-directional Mode Selectable - Single-ended/Differential Mode (noise tolerant) Selectable - AC Coupling Supported with Differential Mode - Transmission Status Error Indicator Supported (Line Cut Detection and Packet Error Detection) - Digital Filter Function. - Power supply : 3.0 to 5.5V - QFN 32-pin Package - EU RoHS Compliant Block Diagram THCS132 Copyright(c)2014 THine Electronics, Inc. 1/19 THine Electronics, Inc.

Pin Setup Pin Function Description SIG IOP ION L CMOS I/O * H Differential mode I/O Differential mode I/O CMOS I/O Differential mode I/O : Please keep pin being opened(No connection) Function of Transmission Status Error Indicator, FAULTN (Receiver mode) FAULTN is the output pin. When the protocol of received data is not correct or serial data more than 50usec (typ) is not received, FAULTN pin will be changed into low level. The received data is canceled when a FAULTN pin outputs Low. When normal serial data is received, a FAULTN pin outputs High in case of pulled up externally. Digital Filter Function When FILT pin is set to high level, the digital filter function is active. If the transmitter matches the 3 sampling frequency content with the deserialized parallel data, it is updated as the correct data. Writing and Reading of Parallel Data by Serial Communication The THCS132 is able to write and read data by 3-wire serial I/F on 16bit register.
