TSC2020EVM

The TSC2020EVM is an evaluation module for TSC2020 resistive multiple touch screen controller (TSC). The evaluation module allows direct evaluation of the TSC2020 performance and operating characteristics, in addition to rapid software development and system prototyping. The TSC2020 device works with a supply voltage as low as 1.6V that can be supplied by a single cell battery. The TSC2020 contains a complete, ultra low power, 12bit, analog to digital converter (ADC) including sensor drivers and the control logic to measure touch pressure. Unlike other resistive touch screen controllers, the TSC2020 is capable of detecting at least three touches simultaneously and delivers a very low power standby touch detection scheme. This flexibility allows for many new applications that require multiple touches but must remain at low power. The TSC2020 supports the I2C serial bus and data transmission protocol for all three defined modes standard, fast, and high speed.
