The economical A/D microcontroller HT46R48A is an 8-bit high-performance reduced instruction set MCU designed specifically for products that require A/D conversion, such as sensor signal input. All microcontrollers integrate multi-channel analog-to-digital converters and 1 or 2 channel PWM outputs. Pause and wake up functions, oscillation type selection, programmable frequency divider, and other functions make practical applications require fewer external devices.
With A/D and PWM, low power consumption, high performance, flexible input/output ports, and low cost, this microcontroller can be widely used in signal processing with sensors, motor drives, industrial control, consumer products, and subsystem controllers. All microcontrollers in this series have the same characteristics, with the main differences being the number of input/output pins, RAM and ROM capacity, A/D resolution, stack layers, and packaging type.
