HE84G770

HE84G770 is a member of 8-bit Micro-controller series developed by King Billion Electronics. External address and data buses are provided to access external memory. This HE84G770 chip has 6400 pixel, 16 gray-scale LCD driver built-in with 4 different configurations, and up to 36-bit general purpose I/O ports. The built-in OP comparator can be used with light, voice, temperature and humility sensor or used to detect the battery low. The 8-bit current-type D/A converter and PWM driver output provides the complete speech output solutions. The 1M bytes ROM and 6K bytes RAM can be used for the storage of large speech data, image and text, etc. An UART is included to provide the serial communication capability. IR output makes it suitable for remote control applications.

The instruction sets of HE84G770 is easy to learn and simple to use. There are only thirty-two instructions and four addressing modes. Most of instructions take only 3 oscillator clocks to complete.

The performance and low power consumption make HE84G770 suitable for battery-powered applications such as translator, data bank, educational toy, digital voice recorder, etc.
