Holtek HT68F60 and HT66F60 Enhanced Flash MCUs

11/16/2011

The present release of the new 12K Word Program Memory devices, the HT68F60 and HT66F60, expands yet further the HT68Fxx and HT66Fxx Enhanced Flash MCU device range. The complete series meets with the industrial specification requirements of -40℃ ~ 85℃ operating temperature and high noise immunity. By integrating Holtek’s In-Circuit Programming technology solution, users have a convenient means of upgrading their application programs. The devices also include an area of EEPROM which can be used to store related production process or product parameters and data, which can retain data even in the absence of the power supply, features which can improve production efficiency and product flexibility.

These new devices have a Program Memory capacity of 12K Words, an SRAM Data Memory capacity of 576 bytes and a 256 byte Data EEPROM. In addition to the Crystal and External RC oscillators, the devices also include an accurate internal high frequency RC Oscillator with a selectable frequency of 4, 8 and 12MHz and an additional low frequency internal 32kHz oscillator. Additional features include 4 software SCOM outputs which can directly drive small pixel count LCD panels and external communication interfaces which include SPI, I²C, UART and USB types, providing users with a wide range of communication possibilities.

Both the HT68F60 and HT66F60 devices include Holtek’s new Timer Modules, which have 5 different operating modes. These include Capture, Compare, Timer/Event, Single Pulse Output and PWM functions. A high speed 12-bit A/D converter is included within the HT66F60 device within which is also integrated a fully internal voltage reference source.

These new devices come supplied in a range of package types from 40 to 52 pins, which together with the abundant range of flexible hardware internal resources, provide MCU solutions for a huge range of products which include household appliances, industrial control, automotive products, medical products to name but a few.

In support of these new devices, Holtek supplies a suite of hardware and software tools. Known as the HT-IDE3000 (Windows®-based), 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 supporting tools ensure that designers have to hand all the resources required for rapid and efficient product development and debug.
