Capacitive Touch Control
Nowadays, the touch sensing technology is getting more attention and have many applications. Comparing with traditional mechanical keys, capacitive touch sensing keys are not only beautiful and fashionable, but also waterproof, longer life, low power consumption, low cost, small size, and durability. It subverts the traditional mechanical button control. With a slight touch, it realizes the switch control of the button, quantitative adjustment and even a directional control. It has been used widely in desk light, air purifier, small home appliances, massage chair and other consumer electronics.

Production specification
GPT1001A
•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.
•Supporting the visual debugging tool, simplifying the process and shortening the time of finetune.
•Supporting 22 touch points maximum.
•Providing a standard code such as keys, slides, knobs to reduce the development lead-time.
•Offering dice, LQPF32 & SSOP20 package.
GPM8F3740A/50A
•GPM8F3750A/GPM8F3740A are highly integrated microcontroller with 2K byte XRAM, 256-byte IDM SRAM and 32K-byte / 16K-byte program FLASH. It supports up to 26 programmable multi-functional I/Os, Timer0/1, CCP0/1, Timer A/B, UART0/2, one SPI (master/slaver), one I2C (master/slaver), one real time counter, one Capacitive Touch Sensor, one 10-channle SAR ADC with 12-bit resolution for general-purpose application. It operates over a wide range of working voltage, from 2.2V through 5.5V, in different clock sources. It has one mode in power management unit. Moreover, there is one on-chip debug circuit with two pins to facilitate full speed in-system debug.
•Supporting the visual debugging tool, simplifying the process and shortening the time of finetune.
•Supporting 23 touch points maximum.
•Touch feature waterproof.
•Offering dice, LQPF32 & SSOP20 package.
