The TinyPowerTM A/D Type 8-bit high performance RISC architecture microcontroller is specifically designed for applications that interface directly to analog signals. The device includes analog features such as an integrated multi-channel Analog to Digital Converter, 12-bit Digital to Analog Converter, DC/DC Converter and LDO.\nWith their fully integrated SPI and I2C functions, designers are provided with a means of easy communication with external peripheral hardware. The benefits of integrated analog features such as A/D, D/A, etc., 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.\nThe UART module is contained in this device. It can support the applications such as data communication networks between microcontrollers, low-cost data links between PCs and peripheral devices, portable and battery operated device communication, etc. This device also includes a Smartcard Interface, which is compatible with and certified to ISO 7816 standards, to provide communication with various types of Smart Card.\nThe unique Holtek TinyPower technology also offers the advantages of 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.
