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.
