The internal features of these new devices will see them having widespread use in the electrical appliance application area for products which require temperature control and voltage measurement, such as water heaters, wine cabinets, disinfectant dispensers, electric ovens, air conditioner controllers etc.
The complete device series includes Holtek’s new Timer Modules which offer five different operating modes. These operating modes are Input Capture, Compare Match Output, Timer/Event Counter, Single Pulse Output and PWM output. All devices contain an internal 12-bit high speed analog to digital converter.
The HT66F0172 includes three oscillator options, a high frequency crystal oscillator, a fully internal low frequency 32kHz RC oscillator and a fully integrated high frequency RC oscillator. The HT66F0174 provides four oscillator options; in addition to the three oscillators of the HT66F0172, it also provides a low frequency 32.76832kHz crystal oscillator. The HT66F0174 also has a 64-byte area of EEPROM which can be used to store non-volatile data such as production process parameters or product parameters and data. Both devices are supplied in 20-pin DIP, SOP and SSOP package types.
Holtek also fully supports these devices with its comprehensive hardware and software development tools. One of these tools is the e-Link, which is a new generation OCDS structure in-circuit debug adapter. When used together with the HT-IDE3000 software development system, users are provided with a suite of development tools to directly debug their application boards which includes trace analysis features. Holtek’s e-WriterPro is a writer which supports ICP to provide a means of easy program updates and development. Holtek also offers a range of application guides to ensure developers have their designs up and running in the shortest time possible.
