HT48R50A-1/HT48C50-1 -- I/O Type 8-Bit MCU

General Description

The HT48R50A-1/HT48C50-1 are 8-bit high performance, RISC architecture microcontroller devices specifically designed for multiple I/O control product applications. The mask version HT48C50-1 is fully pin and functionally compatible with the OTP version HT48R50A-1 device.

The advantages of low power consumption, I/O flexibility, timer functions, oscillator 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.
