NY9T Series

Feature:

• Wide operating voltage range: 2.0V to 6.0V.
• 400KHz instruction frequency.
• Precisely 400KHz oscillator with built-in resistor Rosc for operating mode. (+/- 1% tolerance)
• Very low standby current for Touch-Key scan to reduce the power consumption.
• Low Voltage Reset (1.8V), Watch-Dog Reset and I/O Port reset are all supported to protect the system.
• Maximum 24 flexible I/Os with optional function: General purpose I/O, PWM-IO output or Touch-Key input.
• Maximum 8-channel PWM-IO output of PE0~3 and PF0~3 shared with I/Os. Each output has other 3 kinds of output option: large sink current, constant sink current (CSC) or drive current.
• Programmable PWM-IO has maximum 256 levels LED brightness with software control. The LED frame rate can be selected from 128Hz, 4KHz and 66KHz.
• Maximum 16 Touch-Keys of PA0~3, PB0~3, PC0~3 and PD0~3 shared with I/Os.
• Touch-Key supports simultaneous multi-key or single-key touch function configured by option.
• Hardware Auto-Calibration function of Touch-Key is provided for touch accuracy to prevent the environment change
• 4 kinds of debounce time for Touch-Key press/release detection configured by option in order to keep away from the noise interference.
• 2 kinds of hysteresis level: Small Hysteresis Level and Large Hysteresis Level for all Touch-Keys configured by option.
• 8 kinds of sensitivity levels can be selected by software programming or external RADJ resistor.
