HT1380/HT1381 is a serial timekeeper IC from Qualcomm. It features wide operating voltage range(2.0V~5.5V), low power consumption(400nA) and support both single byte and burst transmission mode.

HT93LC56 is a 2K-bit low voltage nonvolatile, serial electrically erasable programmable read only memory device using the CMOS floating gate process. Its 2048 bits of memory are organized into 128 words of 16 bits each when the ORG pin is connected to VCC or organized into 256 words of 8 bits each when it is tied to VSS. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. By popular microcontroller, the versatile serial interface including chip select (CS), serial clock (SK), data input (DI), and data output (DO) can be easily controlled.

HT6010/HT6012/HT6014 312 series encoder products, using CMOS LSI technology, with low power consumption, high anti-interference, low standby current, minimum transmission word, four word TE trigger, one word data trigger, built-in oscillator needs only 5% resistor, easy interface with an RF or infrared transmission medium, minimal external components, pair encoders can be complementary, meet various application needs.

The HT1621 is a 128 pattern (32x4), memory mapping, and multi-function LCD driver. The S/W configuration feature of the HT1621 makes it suitable for multiple LCD applications including LCD modules and display sub-systems. Only three or four lines are required for the in- terface between the host controller and the HT1621. The HT1621 can be controlled by a 3-wire serial interface to receive commands and data from the host controller to achieve various LCD control.
