0.9V low voltage standard flash MCUs incorporate PMIC functions

These new devices with the part numbers, HT66F016L and HT66F017L, provide a flexible range of integrated user functions. With their low pin count and versatile functions these new devices should find good use in single-cell battery applications such as electric toothbrushes, electric shavers, remote controls and other such consumer products.

The HT66F016L device has 1K of Flash Program Memory, 64 bytes of Data Memory and 64 bytes of Data EEPROM while the HT66F017L has .2K of Flash Program Memory, 128 bytes of Data Memory and also 64 bytes of Data EEPROM. Both devices have fully internal system oscillators and an 8 level stack. With regard to peripheral functions, all devices contain an internal 12-bit high speed analog to digital converter for the measurement of external analog signals, such as those from as temperature or voltage sensors etc. Both devices also include an internal comparator as well as Holtek’s new Timer Modules which provide multi-functional timer operation. These features combine to offer devices which can implement a complete low voltage MCU system with a minimum number of external components.

With regard to support for these new devices, Holtek supplies a suite of hardware and software tools. Known as the HT-IDE3000, this windows based system includes a real time hardware in-circuit emulator and has all the functions one would expect from a high performing development system, such as trace analysis, breakpoints etc. Along with application guides, these support facilities ensure that designers have to hand all the resources required for rapid and efficient product development and debug.
