1 / 61 page  HT46R92 A/D Type 8-Bit MCU with 16´16 High Current LED Driver Rev. 1.10 1 November 5, 2008 General Description The HT46R92 is an 8-bit high performance RISC archi- tecture microcontroller, the device is designed espe- cially for applications that interface directly to analog signals, such as those from sensors. The devices in- clude an integrated multi-channel Analog to Digital Con- verter in addition to two Pulse Width Modulation outputs. An internal high current LED driver circuit also provides for easy interfacing to applications which con- tain LED displays. The usual Holtek MCU features such as power down and wake-up functions, oscillator options, etc. combine to ensure user applications require a minimum of exter- nal components. The benefits of integrated A/D and PWM functions, in addition to low power consumption, high performance, I/O flexibility and low-cost, provides the device with the versatility to suit a wide range of application possibilities such as sensor signal processing, motor driving, indus- trial control, consumer products, subsystem controllers, etc. As is the case with all Holtek microcontroller devices, the HT46R92 is fully supported by a full suite of professional hardware and software tools, containing comprehensive features to ensure user applications are designed and debugged in as short a time as possible.
