HT48F50E -- I/O Type 8-Bit Flash MCU With EEPROM

General Description

The HT48F50E is an 8-bit high-performance, RISC architecture microcontroller devices specifically designed for multiple I/O control product applications. Device flexibility is enhanced with their internal special features such as power-down and wake-up functions, oscillator options, buzzer driver, etc. These features combine to ensure applications require a minimum of external components and therefore reduce overall product costs.

Having the advantages of low-power consumption, high-performance, I/O flexibility as well as low-cost, these devices have the versatility to suit a wide range of application possibilities such as industrial control, consumer products, subsystem controllers, etc.

The device utilises a Flash type Program Memory, and therefore have multi-programmable capabilities offering the advantages of easy and efficient program updates. The non-volatile internal EEPROM also offers the capability of storing information such as product part numbers, calibration data and other specific product information. etc. The device is fully supported by the Holtek range of fully functional development and programming tools, providing a means for fast and efficient product development cycles.
