Holtek Company Introduction
Introduction
After its establishment in 1983 and until the present day, Holtek
Semiconductor has released an unceasing stream of competitive semiconductor
devices onto the global market. While continuing to concentrate its design
efforts in the 8-bit and 32-bit microcontroller development area, the
extensive and increasing range of peripheral semiconductor products should
also not be ignored. At the foundation of these successful product
developments exists many years of semiconductor design experience accumulated
by the company’s professional engineering design teams. The results of these
extensive efforts have led to Holtek customers being provided with a huge
range of high quality industrial grade semiconductor devices. Among Holtek’s
many customers are included a wide array of popular global brand consumer
appliances and industrial products, which shows the global confidence in the
company’s devices. With this background, Holtek remains fully committed to a
continuous expansion of its high quality and superior price-performance
semiconductor devices well into the future.
Product Device Range
Holtek’s product development focus will remain firmly in the microcontroller
area for both 8-bit and Arm® core based 32-bit microcontrollers. These highly
functionally integrated microcontrollers includes digital and analog features
such as A/D converters, comparators, LCD drivers, PWM generators, high current
LED drivers, touch switches, SPI, I2C, UART and USB interfaces, voice
functions, RF functions etc. All of the company’s 32-bit and 8-bit
microcontroller devices meet with full industry specifications in having a
wide voltage and temperature operating range. In addition to its
microcontrollers there exists a wide range of peripheral devices such as
stand-alone touch switch ICs, LCD drivers, power management devices, video
processors, sensors etc, further increasing the Holtek product diversity and
opening up applications into a wider market area.
Product Development Strategy
In following market trends and customer requirements, Holtek’s commitment to
new product development and innovation can be seen through its continuously
expanding device functionality. As the world of IOT continues to extend its
reach into demands for an increasingly connected lifestyle, Holtek’s multi-
function product range stands in a strong position to have a strong presence
in this rapidly expanding market area. The integration of features such as RF
functions, voice, touch key and power management functions into its
microcontroller range demonstrates this commitment to IOT product trends.
Holtek’s range of standard microcontroller products will continue to expand
but alongside it will be the design of application specific products such as
those for motor control, personal health care, home appliances and many
others. With its long history of working alongside its customers to assist in
the design their custom microcontrollers, Holtek welcomes product
manufacturers to contact them to discuss new custom microcontroller design
possibilities. Additionally, and as no functionally rich microcontroller is
useful without an appropriate development platform, all of Holtek’s products
are fully supported by a comprehensive range of hardware and software
development tools to simplify the designer product development process.
Holteks obligation to ISO compliance and its string of innovation awards and
intellectual properties provide further evidence of the companys commitment to
product development excellence.
Marketing Service Network
Holtek’s range of semiconductor products is fully complemented by its
extensive global marketing network with a sales presence in most parts of the
world. Having established a large number of worldwide sales offices and
agents, Holteks global marketing structure is well placed to take advantage of
any new market opportunities and trends as they arise.
Selecting Your Holtek Device
As the range of 8-bit and 32-bit microcontroller devices covers such a vast
range of types and functions, Holtek recommends that customers consult its on-
line Product Selector to assist them in their selection of the most suitable
microcontroller for their specific application. With Holtek continually
releasing new products onto the market, it should be noted that the website
version, rather than the printed version of the selection guide, will contain
the most up to date product information. To use our MCU Product Selector,

8-Bit MCU Programming Tools
Holtek is fully aware that success of their microcontroller device range also
depends upon the availability of high quality development tools. As a result
Holtek has developed a full suite of professional hardware and software tools
to provide designers with an excellent set of development resources to ensure
their applications are designed and debugged as efficiently as possible. In
this section can be found details regarding which set of tools should be used
for each microcontroller device.

HT-IDE3000 Development Environment
The HT-IDE3000 is a fully integrated development system for the Holtek range
of microcontrollers. Working in conjunction with the Holtek ICE hardware
emulator, the HT-IDE3000 system provides a user friendly workbench to ensure
the process of application program development and debug is as efficient and
trouble free as possible. By combining all software tools, such as editor,
cross assembler, linker, library manager, symbolic debuggers as well as
hardware tools, application designers have all the tools required at their
disposal to ensure rapid development and debug of their new designs. An HT-
IDE3000 Users Guide is available for download from the Holtek website, which
provides much more detailed information on the HT-IDE3000 development system.
The HT-IDE3000 development system software is available for free download from
the Holtek website. To ensure that users are provided with the latest
modifications and enhancements to the system and to support new device
releases, Service Packs are regularly provided.

HT-ICE Holtek In-Circuit Emulator
The HT-ICEs are multi-featured hardware emulators to assist designers with the
rapid development of their Holtek MCU applications. Their expansive integrated
hardware and software features, provide designers with a full suite of tools
for rapid and easy product development. At the heart of the system is the
hardware emulator, which can fully emulate Holtek 8-bit MCU devices in real
time as well as providing full debug and trace integrated functions. The HT-
ICE package includes the hardware mainboard platform, CD, flat cables, power
adapter, power cord and printer cable. HT-ICE USB cable allowing customers to
connect the HT-ICE LPT connector to the computer USB port. The part number of
this USB cable is CUSBICECABLE4A. Please contact us for purchasing details.
e-ICE
The e-ICE is Holteks new generation of MCU in-circuit emulators that uses a
real chip EV for device emulation. In this way a more accurate emulation of
device function and characteristics can be implemented. Together with the HT-
IDE3000 software development system the user is provided with a suite of
development tools for rapid MCU product development.
Holtek New Universal Writer e-WriterPro
The e-WriterPro can be used not only as a programming tool for all of Holteks
OTP and Flash devices during the development stage but can also be used for
small to medium volume production purposes.
The e-WriterPro must be used together with a corresponding e-Socket according
to the package type of the MCU that is to be programmed. Devices with the same
package type require only a single e-Socket, thus reducing the problem of
changing different adaptors for different IC part numbers. For all available
Holtek devices, the following e-Socket table shows which one should be used
with which device package type.
