HT82K75R Overview
Description
The device is an 8-bit high performance, RISC architecture microcontroller devices specifically designed for multiple I/O, mouse/keyboard appliances and SPI control product applications. The advantages of low power consumption, I/O flexibility, Timer functions, Watchdog timer, Power Down, wake-up functions together with the optional peripherals such as EEPROM Memory and RF transceiver provide the devices with versatility for industrial control, consumer products, subsystem controllers, RF module control, etc.
Key Features
- Operating voltage
- All I/O pins have falling and rising edge wake-up fSYS= 6MHz: 1.8V~3.3V
- Internal 6MHz RC oscillator for fSYS
- Power down and wake-up functions to reduce function
- Single 16-bit internal timer with overflow interrupt and timer input
- SPI interface shared with I/O lines
- Low voltage reset function (LVR) for DC_DC output power consumption
- Two bit to define microcontroller system clock (fSYS/1, fSYS/2, fSYS/4)
- All instructions executed in one or two machine controlled by configuration option
- Built-in DC/DC to provide stable 2.8V, 3.0V, 3.3V cycles
