HT46R54 General Description


The HT46R53/HT46R54 are 8-bit high performance, RISC architecture microcontroller devices specifically designed for A/D applications that interface directly to analog signals, such as those from sensors. The advantages of low power consumption, I/O flexibility, timer functions, oscillator options, multi-channel A/D converter, Pulse Width Modulation function, HALT and wake-up functions, watchdog timer, as well as low cost, enhance the versatility of these devices to suit a wide range of A/D application possibilities such as sensor signal processing, chargers, motor driving, industrial control, consumer products, subsystem controllers, etc.

HT46R54 Maximum Ratings

Supply Voltage ...........................VSS-0.3V to VSS+6.0V
Storage Temperature ............................-50C to 125C
Input Voltage..............................VSS-0.3V to VDD+0.3V
Operating Temperature...........................-40C to 85C

Note: These are stress ratings only. Stresses exceeding the range specified under Absolute Maximum Ratings may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.
