With its ultra-low standby current, it is suitable for battery-powered and handheld products. In addition, due to its excellent anti-power interference features, the device is also suitable for mains supply applications such as dish dryers, wall switches, juice machines, electric pressure cookers, disinfection cabinets, 3C products etc to name but a few.

The BS83B04A-4 meets with the industrial specifications requirements of -40°C~85°C operating temperature and contains up to 4 touch keys, 4 I/O ports, Program Memory capacity of 2K words, Data Memory capacity of 128 bytes and EEPROM Memory capacity of 64 bytes.

By including an I2C interface, the device can be used as a master MCU device or work together with other MCUs to implement touch key detection. With its integrated high accuracy RC system oscillator, the device application circuit only requires a minimum of external components for its operation. The device is supplied in a 10-pin MSOP package and is pin is compatible with the BS83A04A-3/-4.

Holtek naturally supplies a full suite of excellent hardware and software development tools including its HT-IDE300 software as well as a hardware In-Circuit-Emulator. The hardware emulator is an e-Link which when used together with an OCDS structured MCU, can provide a full range of debug functions such as trace analysis features etc.

With regard to device programming, the Holtek provided e-WriterPro programmer is also capable of implementing full In-Circuit Programming to allow for fast program updates and product development. There are also a range of application guides to ensure developers have their designs up and running in the shortest time possible.
