Product Summary

The LM8300IMT9 is a 4-wire resistive touch screen controller. The controller samples and drives the touch screen without the need of any external hardware. The LM8300IMT9 has a power-saving mode which causes the controller to self-power down when no touch is detected on the touch screen for a specified amount of time. The applications of the LM8300IMT9 are Personal Digital Assistants, Smart Hand-Held Devices, Touch Screen Monitors, Point-of-Sales Terminals, KIOSK, Pagers, Cell Phones.

Parametrics

LM8300IMT9 absolute maximum ratings: (1)Supply Voltage (VCC):7V; (2)Voltage at Any Pin:-0.3V to VCC +0.3V; (3)Total Current into VCC Pin (Source):200 mA; (4)Total Current out of GND Pin (Sink):200 mA; (5)Storage Temperature Range:-65℃ to +140℃; (6)ESD Protection Level:2 kV (Human Body Model).

Features

LM8300IMT9 features: (1)Supports 4 wire resistive touch panels; (2)Low power standby current typically less than 2 μA at 5.5V; (3)Maximum speed of 500 coordinate pairs per second; (4)Automatic wake up and return to standby; (5)10 bit A/D; (6)On-chip touch screen current drivers - no external driver required; (7)UART interface; (8)Controller configurations are stored in the internal non-volatile storage element; (9)Touch pressure can be measured.
