TSC2005IYZLR

TSC2005IYZLR is a Texas Instruments 4-wire resistive touch screen controller with an SPI host interface in a DSBGA-28 (YZL) chip-scale package. It offers programmable 10-bit or 12-bit resolution, an SPI clock up to 25 MHz, and a 1.6 V to 3.6 V supply range, drawing 800 uW at 1.8 V and 50 samples per second, 600 uW at 1.6 V, and as little as 75 uW at 1.6 V at an 8.2 kSPS rate. On-chip temperature and pressure measurement are included, and ESD protection is rated +/-6 kV HBM, +/-25 kV air-gap and +/-12 kV contact across -40 °C to +85 °C. The benefit is the family's smallest footprint, for high-density handheld layouts where board area, not assembly convenience, drives the choice. For buyers, two limits define this code: it is offered only in DSBGA-28, and its supply floor is 1.6 V, so a design that needs a true 1.2 V rail or a QFN package should take the TSC2006IRTJR instead. Evidence: TI lists TSC2005IYZLR as ACTIVE on the TSC2005 product page, with the parameters above documented in the device datasheet. Selection advice: confirm your assembly flow supports DSBGA before committing.
