HT48R0AA-1 -- Cost-Effective I/O Type 8-Bit OTP MCU
General Description
The HT48R0AA-1 is an 8-bit high performance, RISC
architecture microcontroller devices specifically designed for cost-effective multiple I/O control product applications.
The advantages of low power consumption, I/O flexibility,
timer functions, oscillator configuration options, HALT and wake-up functions, Watchdog Timer, buzzer
driver, as well as low cost, enhance the versatility of these devices to suit a wide range of application
possibilities such as industrial control, consumer products, subsystem controllers, etc.
