The device can display up to 312 pixels, including an I2C interface and supports 1/4 duty or 1/8 duty display driving. As well as fully packaged devices, Holtek also provides a COG version device, the HT9B95G. The HT9B95’s features of high quality and low power consumption make it also suitable for applications such as electronic tags, bank cards, audio equipment, industrial metering, home appliances as well as other consumer product applications which have LCD panel display requirements.

The device has a wide operating voltage of 2.4V~5.5V and contains an 8x39 bits display memory among which some display data can be changed by direct addressing. Having an independent external VLCD voltage source input and an internal VLCD voltage adjustment circuit with a 32-level voltage selection, the device can provide the optimum VLCD voltage based on the LCD characteristics to achieve the best quality display. It also provides two selectable LCD inversion waveforms as well as four selectable power saving modes. Users can choose their most suitable mode according to their power consumption and display quality requirements.

This new device has an internal power on reset circuit and supports four frame frequencies of 80Hz, 71Hz, 64Hz and 50Hz. The highly integrated design allows for easy data transmission between the device and the system host MCU which requires only two signal lines thus greatly reducing the need for external components. This greatly simplifies routing and results in overall reduced system costs. The device is supplied in 48-pin TSSOP and 52-pin LQFP package types as well as a Gold Bump Dice version.
