Version:V1.1
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 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 HE80004H series 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 it suitable for battery-powered applications such as
translator, data bank, educational toy, digital voice recorder, etc.
