NY9U Series

NY9U

4-bit MCU with Universal / Remote Controller

The NY9U series is a powerful 4-bit MCU with remote controller. It has 16 I/O ports and supports T-type key matrix. One large sink current IR port can fulfill transmitting and receiving function without any bipolar transistor. The RISC MCU architecture is very easy to use, and various applications can be easily implemented. Furthermore, it provides the HALT mode (sleep mode) to extend battery life.

Feature:

Operating voltage range: 2.0V to 3.6V.
HALT mode to save power, standby current <1uA @3V, battery-off current <0.1uA @1.3V.
Precisely embedded oscillator with build-in resistor, +/- 1.5% deviation in 2.0V~3.6V and -20°C~+70°C.
Low voltage reset (LVR=1.8V), watch-dog reset and I/O port reset are all supported to protect the system.
2.2V or 2.3V LVD flag for low battery detection.
M-Type, T-type or mixed type key wakeup supported.
Infrared port provides TX and RX application, optioned with large current IR carrier output for TX.
12-bit readable timer with selectable timer clock source for IR TX carrier frequency and RX learning counter.
Programmable code protection is provided. (When the Security-Bit is burnt down, data can’t be read.)
