TSC2008TRGVRQ1

TSC2008TRGVRQ1 is a Texas Instruments automotive-qualified 4-wire resistive touch screen controller with an SPI host interface in a VQFN-16 (RGV) 4x4 mm package. It shares the TSC2046-compatible command set of the TSC2008 family, with programmable 8-bit or 12-bit resolution, 20 kHz throughput at 8-bit and 10 kHz at 12-bit, an SPI clock up to 25 MHz, and a 1.2 V to 3.6 V supply and reference range drawing 30.4 uA at 1.2 V under the datasheet conditions. What sets this code apart is the automotive qualification itself: it is characterized from -40 °C to +105 °C, where the industrial TSC2008 stops at +85 °C, and its latch-up performance exceeds 100 mA per JESD78B Class I. The benefit is a Q1 touch controller for cabin and body electronics that keeps working at dashboard temperatures while reusing the family's command model. For buyers, do not substitute the industrial TSC2008IRGVR for this code in an automotive BOM; the Q1 suffix marks the qualification, not a packing variant. Evidence: TI's package option addendum lists TSC2008TRGVRQ1 in production, with the parameters above documented in the TSC2008-Q1 documentation. Selection advice: confirm the +105 °C requirement and the Q1 documentation your program needs at RFQ stage.
