General Description

NY8TM52D is a MTP 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. NY8TM52D adopts advanced CMOS technology to provide customers remarkable  solution with low cost and high performance benefits. RISC architecture is applied to NY8TM52D 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, NY8TM52D is very suitable for those applications that are  sophisticated but compact program size is required.

NY8TM52D provide on-chip debug (OCD) facilities as a low cost alternative to ICE. With OCD and a minimum of  extra hardware, NY8TM52D can do ICE tasks such as free running, single stepping, break point setting and internal  ram/register accessing.

As NY8TM52D 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, NY8TM52D has built-in infrared (IR) carrier generator with  selectable IR carrier frequency and polarity for applications which demand remote control feature. Multiple  Touch-Keys is from 1 touch key up to 4 touch keys configured by register option. A built-in LDO regulator for touch  sensor can provide a stable capacitive sensing design for touch application. An innovative software tool "Q-Touch" is  provided to develop the different touch applications

NY8TM52D also provides 2 sets of timers which can be used as regular timer based on system oscillation or event  counter with external trigger clock. Moreover, NY8TM52D provides 3 set of 10-bit resolution Pulse Width Modulation  (PWM1/2/3) output and 1 set buzzer output in order to drive motor/LED and buzzer.

NY8TM52D employs dual-clock oscillation mechanism, both high oscillation or low oscillation can be derived from  internal resistor/capacitor oscillator. Moreover, based on dual-clock mechanism, NY8TM52D 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.

While NY8TM52D operates in Standby mode and Halt mode, kinds of event will issue interrupt requests and can  wake-up NY8TM52D to enter Normal mode and Slow mode in order to process urgent events.
