Product Descriptions

NY8A056A is an 8-bit microcontroller designed for I/O applications such as home appliances or measurement, using EPROM as memory. Adopting CMOS process while providing customers with significant advantages such as low cost, high performance, and high resistance to electromagnetic interference. The NY8A056A core is built on the RISC reduced instruction set architecture, making it easy to edit and control, with a total of 55 instructions. Except for a few instructions that require 2 timing sequences, most instructions can be completed in 1 timing sequence, allowing users to easily control different applications through programming. Therefore, it is very suitable for various complex applications with low to medium memory capacity.

In terms of I/O resources, NY8A056A has 16 flexible bidirectional I/O pins, each with a separate register to control as an input or output pin. And each I/O pin has additional program control functions such as pull-up or pull-down resistors or open drain outputs. In addition, for infrared remote control products, NY8A056A has a built-in high current output infrared carrier emission port with selectable frequency, and the current can reach 340mA when powered by 3V.

NY8A056A has three sets of timers, which can be used as general timing applications with system frequency or triggered by external signals to count. In addition, NY8A056A provides two sets of 8-bit resolution PWM outputs or buzzer outputs that can be used to drive motors LED、 Or buzzers, etc.
