Please contact sales person for the latest version before use. King Billion Electronics Co., Ltd www.DataSheet4U.com HE84760 HE80000 SERIES 1. General Description HE84760 is a member of 8-bit Micro-controller series developed by King Billion Electronics. There are 3 LCD configurations: 32COM x 96SEG, 48 COM x 80 SEG and 64 COM x 64 SEG available by mask option. 24 LCD segment driver pins are multiplexed with I/O pins to provide flexibility of wide variety of combinations to suit the needs of applications. The built-in LCD power supply is equipped with voltage charge pump to generate the high voltage required by the high duty LCD driver, bias voltage generating circuit and input voltage regulator circuit to supply stable LCD display effect over the wide battery life. The built-in OP comparator can be used with (light, voice, temperature, humility) sensor or battery low detection. Built-in two-channel sinusoidal wave generator can be used to generate telecom tones such as DTMF tone dialing signal, Caller Alerting Signal (CAS) tone, FSK signal as well other tones with frequencies ranging from 1 ~ 4095 Hz. A 7-bit current type D/A converter and PWM device provide the complete speech output mechanism. The 512K byte ROM and 4K byte RAM can be used as the storage of large speech data, graphic, text, etc. It is ideal for applications such as Translator, Data Bank, Educational Toy, Digital Voice Recording System, Short Message Service phone, etc. The instruction set of HE80000 series is easy to learn and simple to use. Only 32 instructions with four addressing modes are provided. Most of instructions take only 3 oscillator clocks to execute. 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 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 Operation Voltage: Internal ROM: Internal RAM: Dual Clock System: 2.4V ~ 3.6V 512 KB (256K Program ROM+256K Data ROM) 4 KB Fast clock: 32768 ~ 8M Hz Slow clock: 32768 Hz 4 operation modes: Fast, Slow, Idle, and Sleep modes. 16 ~ 40 bit bi-directional general purpose I/O ports with push-pull or open-drain output type selectable for each I/O pin by mask option. Built-in 4x20 hardware keyboard scan circuit (multiplexed with LCD SEG pin) helps to reduce the pin counts as well as the firmware effort. Three LCD configurations: 32COM x 96SEG, 48 COM x 80 SEG and 64 COM x 64 SEG. Built-in LCD power supply with input voltage regulator, voltage charge pump and bias voltage generating circuit. LCD Segment Extender Interface to connect with.
