HT46RS03/HT46RS03P -- 2K 8-Bit OTP MCU with OPA & Comparator
General Description
The HT46RS03/HT46RS03P is an 8-bit, high performance,
RISC architecture microcontroller device specifically designed for operational amplifier applications
that can be used to interface directly to ultrasonic transducers.
The advantages of low power consumption, I/O flexibility,
programmable frequency divider, timer functions, oscillator options, internal comparator, internal operational
amplifiers, power-down and wake-up functions, enhance the versatility of these devices to suit a wide
range of application possibilities such as remote control appliances, car reversing systems, level meters, etc.
