3 / 60 page  KING BILLION ELECTRONICS CO., LTD 駿 億 電 子 股 份 有 限 公 司 HE84G761B HE80004 Series April 25, 2005 3 V0.92 This specification is subject to change without notice. Please contact sales person for the latest version before use. 1. General Description HE84G762B 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 384K bytes ROM and 5K 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. 2. Features Operation Voltage: 2.4V ~ 3.6V Dual Clock System: Fast clock 32768 Hz ~ 8 MHz Slow clock 32768 Hz Four operation modes: Fast, Slow, Idle, Sleep modes. Internal Program ROM: 384K bytes Internal RAM: 5 K bytes External memory buses to interface external Mask ROM, EPROM, NOR FLASH memory, etc. 22 ~ 34 bi-directional general-purpose I/O ports with push-pull or Open-Drain output type selectable for each I/O pin by mask option. Up to 4096 pixels 16, 4 gray-scale or Black/White LCD driver. Segment extender interface with KD83 and KD80. 4 LCD configurations (COM X SEG): 32 COM x 96 SEG, 48 COM x 80 SEG, 64 COM x 64 SEG, 80 COM x 48 SEG. Built-in LCD power supply with regulator and 3, 4, and 5 times charge pump circuit. One 7/8-bit current-type D/A converter. One 7/8-bit PWM output. One built-in OP comparator. Built-in UART for serial communication. IR output. Low voltage reset: 2.2V Low voltage detection: 2.4V, 2.6V, 2.8V and 3.0V Two external interrupts, three internal timer interrupts and extension UART interrupt Watch dog timer to prevent deadlock condition. Two 16-bit timers and one time-base timer. Instruction set: 32 instructions, 4 addressing mode. |
