New Holtek HT68Fxx, HT66Fxx Enhanced Flash MCU Device Series

11/11/2009

Holtek is delighted to announce the release of its new Enhanced Flash series MCUs, in the form of its I/O type HT68Fxx series and the A/D type HT66Fxx series. All devices meet with full industrial specifications (-40℃~85℃) and have high noise immunity. Together with their In-System Programming capabilities, the devices permit program modifications to be easily implemented with the device still in-circuit. All of these devices include an area of non-volatile EEPROM memory which can be used to save data such as product parameters or manufacturing data all of which will be retained even when power is removed, a feature which greatly enhances product flexibility.

Both of these new Enhanced Flash MCU device series include 2~8K words of Program Memory, 96~384 bytes of SRAM Data Memory and 64~256 bytes of data EEPROM. In addition to their crystal and external RC oscillators, all devices also include a fully internal RC oscillator, which requires no external components and can provide fixed frequencies of 4MHz, 8MHz and 12MHz. Another internal RC oscillator can provide a fixed 32kHz frequency. There are also four software COM outputs to drive LCD panels as well as SPI, I²C, UART and USB interfaces for communication with the outside world. A huge range of other features also exist to enhance the flexibility of these new devices.

The HT68Fxx and HT66Fxx series devices also include Holtek’s new multi-function timer modules. These new timer modules are capable of providing functions such as Input Capture, Compare Match Output, Timer and Event Counting, Single Pulse Generation and PWM signal generation. All devices in the A/D type HT66Fxx series also contain a 12-bit high speed ADC and internal voltage reference function.

The series is supplied in a wide range of package types from 16~48 pins. With their exceptional hardware resources and application flexibility, these Enhanced Flash MCUs will find excellent use in a wide range of application areas such as household appliances, industrial control, automotive applications, medical care products to name but a few.

To support these new devices, Holtek supplies a full suite of hardware and software tools known as the HT-IDE3000 which includes an In-Circuit-Emulator, full trace analysis functions as well as many other functions to ensure that users have their designs up and running in the shortest time possible.
