1 / 127 page  HT56R22/HT56R23/HT56R24/HT56R25/HT56R26 TinyPowerTM A/D Type 8-Bit OTP MCU with DAC Rev. 1.30 1 December 26, 2014 General Description These TinyPower TM A/D Type 8-bit high performance RISC architecture microcontrollers are specifically, de- signed for applications that interface directly to analog sig- nals. The devices include an integrated multi-channel Analog to Digital Converter, Pulse Width Modulation and and DAC outputs. With their fully integrated SPI and I 2C functions, design- ers are provided with a means of easy communication with external peripheral hardware. The benefits of inte- grated A/D, PWM and DAC functions, in addition to low power consumption, high performance, I/O flexibility and low-cost, provides the device with the versatility for a wide range of products in the home appliance and in- dustrial application areas. Some of these products could include electronic metering, environmental moni- toring, handheld instruments, electronically controlled tools, motor driving in addition to many others. The unique Holtek TinyPower technology also gives the devices extremely low current consumption characteris- tics, an extremely important consideration in the present trend for low power battery powered applications. The usual Holtek MCU features such as power down and wake-up functions, oscillator options, programmable frequency divider, etc. combine to ensure user applica- tions require a minimum of external components.
