Holtek HT86Axx New A/D type Voice Series MCUs

April 7, 2010

Holtek is pleased to announce the release of its new series of A/D type Voice microcontrollers. Within this new range are included the HT86A36, HT86A72, and HT86AR72 devices offering the users a wide range of voice capacities of 36 and 72 seconds as well as Voice ROM capacities of 96Kbyte and 192Kbyte. The HT86AR72 is an OTP type MCU which can be used as a development device for both the HT86A36 and HT86A72 during product design.

The HT86Axx series includes a Holtek 8-bit MCU core, a high resolution single channel audio 12-bit DAC, a 1.0W Power AMP for direct speaker driving as well as a 4-channel 12-bit Analog to Digital Converter and RTC function. The HT86Axx series is not only suitable for applications such as high level toys and voice broadcast equipment, but by having an internal RTC wake-up function will also find applications in products with low power consumption requirements. The inclusion of a fully integrated 1.0W Power amplifier ensures that the requirements on external components are kept to a bare minimum.

The special features of this new series of voice devices lie in their high sound quality, low power consumption, low cost etc. giving them superiority over anything else on the market. Their internal power amplifier’s direct speaker driving capability, the low demand on external components, excellent noise immunity and wide temperature range of -40°C~+85°C, render the devices extremely suitable for products such as exercising equipments, tire pressure gauges, smoke detectors, high-level toys, voice broadcast equipment etc. Using the HT86Axx in their product design series enables all of these product applications to easily implement voice functions.

In the area of development tools, the HT86Axx series of MCUs includes both assembler and C-language programming support, which together with Holtek’s comprehensive HT-ICE development environment, ensures that designers have a full suite of hardware and software tools at their disposal for rapid product development.
