HE84G752B 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 4096 pixel, 16
gray-scale LCD driver built-in with 4 different configurations, and up to 34-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 7/8 bits current-type D/A converter and PWM driver output provides the
complete speech output solutions. The 512K bytes ROM and 3K 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 HE80000 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.
