NY8A/B Series

NY8A/B Series

8-bit OTP/MTP MCU for Home Appliance

NY8A/B series is an EPROM based 8-bit MCU tailored for I/O based applications like home appliances or meter equipment. NY8A/B series adopts advanced CMOS technology to provide customers remarkable solution with low cost, high performance and high noise immunity benefits. RISC architecture is applied to NY8A/B series and it provides 55 instructions. All instructions are executed in single instruction cycle except program branch and skip instructions which will take two instruction cycles. Therefore, NY8A/B series is very suitable for those applications that are sophisticated but compact program size is required.

NY8A/B series employs dual-clock oscillation mechanism, either high oscillation or low oscillation can be derived from internal resistor/capacitor oscillator or external crystal oscillator. Moreover, based on dual-clock mechanism, NY8A054A provides kinds of operation mode like Normal mode, Slow mode, Standby mode and Halt mode in order to save power consumption and lengthen battery operation life. Moreover, it is possible to use internal high-frequency oscillator as CPU operating clock source and external 32KHz crystal oscillator as timer clock input, so as to accurate count real-time and maintain CPU working power.
