Product Descriptions

NY8A054E is an 8-bit microcontroller designed for multi group PWM applications, with EPROM as the memory. For example, light control and remote control car applications. Adopting CMOS process while providing customers with significant advantages such as low cost, high performance, and high cost-effectiveness. The NY8A054E 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 timings, most instructions can be completed in 1 timing, 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, NY8A054E has 14 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, NY8A054E has a built-in infrared carrier emission port with selectable frequencies.  

NY8A054E 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, NY8A054E provides 5 sets of 10 bit resolution PWM outputs, and 1 set of buzzer output can be used to drive motors LED、 Or buzzers, etc.
