The device includes 4K Words of Flash Program Memory, 256 bytes of RAM Data Memory, 64 bytes of Data EEPROM Memory and an 8-level stack. With regard to peripheral functions, the device includes multifunctional Timer Modules, external interrupts, I2C and UART interfaces, internal and external high accuracy oscillators etc.
In addition to operating independently, the device can use its 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 at hand a highly functional device with which to easily develop their small household appliance products.
Holtek naturally also fully supports this new device with its comprehensive hardware and software development tools. The hardware development tool is known as the e-Link which works together with an OCDS structured evaluation MCU, providing users with an actual device with which full emulation and debug can be implemented.
The software development tool is known as the HT-IDE3000, which includes features such as real time emulation, full memory and register access, hardware breakpoints complete with logical setups, trace analysis etc. This range of development tools ensure that designers have all the resources at hand to provide for rapid and efficient design and debug of their microcontroller based new product applications.
