HT49RA0 General Description
The HT49RA0/HT49CA0 are 8-bit high performance, RISC architecture microcontroller devices specifically designed for multiple I/O control product applications. The mask version HT49CA0 is fully pin and functionally compatible with the OTP version HT49RA0 device.
The advantages of low power consumption, I/O flexibility, timer functions, oscillator options, watchdog timer, HALT and wake-up functions, as well as low cost, enhance the versatility of this device to suit a wide range of application possibilities such as industrial control, consumer products, and particularly suitable for use in products such as infrared LCD remote controllers and various subsystem controllers.
The HT49CA0 is under development and will be available soon.
