TSC2006IRTJR

TSC2006IRTJR is a Texas Instruments 4-wire resistive touch screen controller with an SPI host interface in a QFN-20 (RTJ) 4x4 mm package. It provides programmable 10-bit or 12-bit resolution with an SPI clock up to 25 MHz, runs from 1.2 V to 3.6 V, and draws 707 uW at 1.8 V and 50 samples per second, falling to 280 uW at 1.2 V and 43 uW at 1.2 V at an 8.2 kSPS rate. On-chip temperature and pressure measurement are included, with ESD ratings of +/-8 kV HBM, +/-25 kV air-gap and +/-12 kV contact across -40 °C to +85 °C. The benefit is the combination the rest of the family splits apart: a fast SPI link, a true 1.2 V minimum supply, and a solderable QFN that standard assembly and rework flows handle easily. For buyers, this is the SPI choice when the host rail can sit at 1.2 V; the TSC2005 offers the same interface family only in DSBGA and only down to 1.6 V. Evidence: TI lists TSC2006IRTJR as ACTIVE on the TSC2006 product page, with the parameters above documented in the device datasheet. Selection advice: match the full IRTJR code so the QFN-20 package is what ships.
