summary

  HT46R62 / HT46C62 is eight high performance reduced instruction set and single chip microcomputer, specifically for need A/D conversion and LCD display products and design. Their film version HT46C62 OTP with pins and function HT46R62 version of the same.

  Low power consumption and the I/O use agile, counter, oscillation type selection, multi-channel A/D transformation, pulse function, suspension and sensei function, and LCD display function, make this kind of single chip can be widely used in need A/D conversion and LCD display products, such as electronic measurement instruments, environment monitoring, portable measuring tools, motor control and other industrial and family system.
