The LM8500IMT9 from Texas Instruments is a 4-wire resistive touchscreen controller designed for efficient touch detection and coordinate sampling. It integrates a 10-bit Analog-to-Digital Converter (ADC) capable of up to 500 coordinate pairs per second (cpps), with data output via a UART interface at 38400 bps.
This controller operates within a voltage range of 2.7V to 5.5V and has a typical operating current of 11.5 mA. It features a power-saving mode that reduces current draw to less than 2 µA when no touch is detected, automatically waking upon touch or UART communication. The device also includes an internal non-volatile memory for storing configuration data like calibration points.
Packaged in a 48-TSSOP, the LM8500IMT9 is designed for surface mounting. It operates across a temperature range of 0°C to 70°C, making it suitable for various consumer electronics and embedded systems requiring touch input functionality.
The operating voltage range is 2.7V to 5.5V.
The operating temperature range is 0°C to 70°C.
It supports 4-wire resistive touch panels.
The ADC resolution is 10 bits.
It uses a UART interface.
The standby current is typically less than 2 µA.
