HT46R48E - Economic A / D Type 8-Bit OTP MCU 

 Summary 

 HT46R48E eight high-performance RISC microcontroller, designed specifically for A / D converter products, such as sensor signal input. 

 Piece of HT46R48E package contains two chips: a HT46R48 microcontroller, and the other one as a general-purpose data memory, 128 × 8-bit EEPROM. The two chip bonding together the package for HT46R48E. 

 Low-power I / O using a flexible, programmable frequency divider, timer functions, oscillator options, multi-channel A / D conversion, pulse measurement capabilities, suspend and wake-up function, so that this single chip can be widely used sensors A / D conversion, motor control, industrial control, consumer products and other systems.
