Features: SpecificationsDescriptionThe HE83540 has the following features including 1624 bit Bi-directional I/O port. Mask Option can select PUSH-PULL or OPEN DRAIN output mode for each I/O pin;One built-in OP comparator;1024896 dots LCD driver (B TYPE selectable);One 7-bit current-type DAC output;PWM device;Built-in DTMF Generator;Two external interrupts and three internal timer interrupts;Three 16-bit timer.
HE83540 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd.Users can chose any one of combination among[1024 dots LCD Driver+16 Bit I/O Port].[896 dots LCD Driver+24 Bit I/O Port] etc. The built-in OP comparator can be used with (light,voice,temperature,humility) sensor and used as battery low detection. And the 7-bit current-type D/A converter and PWM device provide the complete speech output mechanism. The built-in DTMF generator can generate the PSTN dialing tone directly. The 512K ROM Size can be used in the storage of large speech data, graphic, text etc. It can be applicable to the medium systems such as Small-Scale Dictionary, Data Bank, Pocket Dialer, Automatic Dialer Machine, Medium Class Educational Toy, Lower Second Voice Recording System etc.The instruction set of HE83540 are quite easy to learn and simple to use. Only about thirty instructions with four-type addressing mode are provided. Most of instructions take only 3 oscillator clocks (machine cycles). The processing power is enough to most of battery operation system.
The information of HE83540 given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics. Before ordering, purchasers are advised to contact the Sensitron Semiconductor sales department for the latest version of the datasheet(s).In cases where extremely high reliability is required (such as use in nuclear power control, aerospace and aviation, traffic equipment,medical equipment, and safety equipment), safety should be ensured by using semiconductor devices that feature assured safety or by means of users' fail-safe precautions or other arrangement.
