Overview
The Enhanced I/O MCUs are a series of 8-bit high performance, RISC architecture microcontrollers 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 main- taining a high level of cost effectiveness.
- Operating voltage: fSYS= 4MHz: 2.2V~5.5V fSYS= 8MHz: 3.0V~5.5V fSYS= 12MHz: 4.5V~5.5V
- Up to 0.33ms instruction cycle with 12MHz system clock at VDD= 5V
- Oscillator types: External high freuency Crystal -- HXT External RC -- ERC Internal high frequency RC -- HIRC External low frequency crystal -- LXT
- Three operational modes: Normal, Slow, Sleep
- Fully integrated internal 4MHz, 8MHz and 12MHz os- cillator requires no external components
- Watchdog Timer function
- LIRC oscillator function for watchdog timer
- All instructions executed in one or two instruction cycles
- 63 powerful instructions
- Up to 4-level subroutine nesting
