Product Descriptions

NY8AE51F is a MTP/EEPROM based 8-bit MCU tailored for I/O based applications like remote controllers, fan/light controller, game controllers, toy and various controllers. The MTP offers the advantage of convenient and effective way of developing user program. The EEPROM, unlike SRAM, features data retention after IC is powered off. NY8AE51F adopts advanced CMOS technology to provide customers remarkable solution with low cost and high performance benefits. RISC architecture is applied to NY8AE51F and it provides 53 instructions. All instructions are executed in single instruction cycle except program branch and skip instructions which will take two instruction cycles. Therefore, NY8AE51F is very suitable for those applications that are sophisticated but compact program size is required.

As NY8AE51F address I/O type applications, it can provide 6 I/O pins for applications which require abundant input and output functionality. Moreover, each I/O pin may have additional features, like Pull-High/Pull-Low resistor and open-drain output type through programming. Moreover, NY8AE51F has built-in infrared (IR) carrier generator with selectable IR carrier frequency and polarity for applications which demand remote control feature.
