The devices include an integrated multi-channel Analog to Digital Converter, Pulse Width Modulation outputs and an LCD/LED driver. With their fully integrated SPI and I2C functions, designers are provided with a means of easy communication with external peripheral hardware. The benefits of integrated A/D, LCD, and PWM 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 industrial application areas. Some of these products could include electronic metering, environmental monitoring, 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 characteristics, 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 applications require a minimum of external components. Mask type devices, the HT56C668 and HT56C678, are also available for volume production products.
