Driver + 24 Bit I/O Port銆慹tc. which is determined by mask options. The built-in OP comparator can be
used with light, voice, temperature and humility sensor or used to detect the battery low. The 7-bit
current-type D/A converter and PWM drive output provide the complete speech output mechanism. The
built-in DTMF generator can generate the PSTN dialing tone directly. The 512K bytes ROM size can be
used in the storage of large speech data, image and text etc. It can be applicable to the medium systems
such as small-scale dictionary, data bank, pocket dialer, automatic dialer machine, medium level
educational toy, lower second voice recording system or used with external command mode SRAM or
Flash RAM for higher second voice recording etc.
The instruction sets of HE80000 series 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 performance of HE83750S is enough for most of battery operation system.
