  Differing from the traditional OTP and Mask type technology, Holtek is pleased to announce the release of a new HT83F02 Flash type Voice device. Although OTP technology devices are user programmable, after initial programming no further memory content modifications are possible. As this new HT83F02 device includes Flash type memory, its memory contents can be re-programmed as many times as the user likes. The in-circuit programmable interface also permits device programming even after the device is soldered onto its application PCB. The internal SPI interface can also be used to program the contents of externally connected voice Flash Memories. Voice functions are becoming an increasingly prominent feature in many home appliances, however the requirement to supply voice content in multiple languages can create logistical difficulties for product manufactures. However using Holtek’s new HT83F02 Flash device, the problems of multiple languages and stock management can be easily resolved. Using standard external SPI Flash Memory types, users are free to choose from a range of different memory sizes with flexibility according to different application requirements.

  In addition to an internal HOLTEK 8-bit embedded microcontroller, the HT83F02 also includes an integrated Flash Program Memory, high speed SPI and I²C interfaces, a monophonic 12-bit voltage type DAC and a PWM driver which can directly drive 8 or 16 ohm speakers. Requiring very few external components and having high noise immunity and a wide operating temperature of -40°C~+85°C, this new device ensures that users are provided with a range of simple and rapid solutions to their voice product application requirements.
