Accessory ASIC 
NY9T Series - Long Standby 4-bit MCU with Touch-Key & LED Controller

The NY9T series IC is a powerful 4-bit micro-controller based LED control processor with capacitive touch sensing function. The RISC MCU architecture is very easy to program and control, and various applications can be easily implemented. There are total 45 instructions, and most of them are executed in one cycle.
Through the accurate 400kHz internal oscillation of ±1% tolerance, an external resister is not required. Furthermore, a RC16K mode is designed to save power consumption and a HALT is to minimize the power.
There are maximum 8 channels of PWM-IO LED output. PWM-IO output can provide 4 kinds of analog output current cooperating with 256-level software digital current control to drive different brightness LED. The optional constant current is provided to protect LED, and it’s not necessary to add the external current-limit resistor. The interactive software-developing tool of “Q-Visio” is user-friendly and quick for LED pattern programming.
The Touch-Key function replaces the mechanical switch or button. Multiple Touch-Keys is from 1 touch key up to 16 touch keys. A built-in LDO regulator for touch sensor can provide a stable capacitive sensing design for touch application. The auto distinguishing methodology supports the diversity key pattern in a thickness range of non-conductive dielectric material, and time sharing Touch-Key scan also reduces the power consumption. An innovative software tool “Q-Touch” is provided to develop the different touch applications.
