HT48R01A -- Small Package I/O Type 8-Bit OTP MCU

General Description

The HT48R01A is 8-bit high performance, RISC architecture microcontroller specifically designed for a wide range of applications. The usual Holtek microcontroller features of low power consumption, I/O flexibility, timer functions, oscillator options, power down and wake-up functions, watchdog timer and low voltage reset, combine to provide devices with a huge range of functional options while still maintaining cost effectiveness. Their fully integrated system oscillator, with three frequency selections, and being supplied in an extremely small outline MSOP 10-pin package opens up a huge range of new application possibilities for these devices, some of which may include industrial control, consumer products,
household appliances subsystem controllers, etc.
