GENERAL TOUCH SENSOR CONTROLLER
1. GENERAL DESCRIPTION
The GPT1001A, a general purpose touch sensor controller, equips
an 8-bit CMOS microprocessor, 8K-byte embedded flash, and
256-byte working SRAM. It allows the control of 24 IOs
configurable as capacitive sensing buttons or GPIOs. Moreover,
three PWMs are built-in to support hardware LED control with hold
and dimming function. The PWM can output to IOB or IOC
individually to produce fancy LED effect with simple program. To
communicate with host devices, the GPT1001A equips SPI or I2C
interfaces. The GPT1001A operates at a wide voltage range of
2.6V – 5.5V. The maximum CPU frequency runs up to 8MHz.
Sleep mode and halt mode are also provided to optimize system
performance and power consumption. The In-Circuit Emulation
(ICE) function is built-in with on-chip re-programmable non-volatile
memory.

GPT1001A
GPT1001A
This IC substrate should be connected to VSS or kept floating.
Note1: To ensure IC functions properly, bond all VDD and VSS pins.
Note2: The 0.1μF capacitor between VDD and VSS should be placed to IC as close as possible.
