These new devices provide plentiful system resources and meet with industrial specification requirements of -40°C~85°C operating temperature as well as having excellent noise immunity. Their internal LED/LCD drivers support 4 segments with current output control which are able to drive LED/LCD displays directly without requiring additional external current-limiting resistors or transistors. With fewer external component requirements and the resulting cost reductions, the devices will find excellent use in products such as household appliances which require an LED/LCD display.

These new devices have a Flash Program Memory capacity of 2K/4K words, an SRAM Data Memory capacity of 128/256 bytes, an EEPROM of 64/128 bytes and 8 level stack. As for peripheral functions, these devices contain multifunctional Timer Modules, a 12-bit ADC, comparators, external interrupts, SPI, I2C and UART interfaces, internal and external high accuracy oscillators etc.

In addition to operating independently, the devices can use their communication interfaces to work together with other master devices as part of an overall system. With this wide range of integrated and versatile functions, users have a range of devices with which to easily develop their small household appliance products.

Holtek also fully supports these devices with its comprehensive hardware and software development tools. One of these tools is the e-Link, which is a new generation OCDS - On Chip Debug Support - structure in-circuit debug adapter. When used together with the HT-IDE3000 software development system, users are provided with a suite of development tools to directly debug their application boards.

Holtek’s e-WriterPro is a writer which supports ICP - In-Circuit Programming - to provide a way for easy program updates and program development. Holtek also offers a range of application guides to ensure developers have their designs up and running in the shortest time possible.
