8-Bit CMOS Microcontrollers with USB
• High-performance RISC CPU
• Only 35 single word instructions
• All single cycle instructions except for program branches which are two cycle
• Interrupt capability (up to 12 internal/external interrupt sources)
• Eight level deep hardware stack
• Direct, indirect and relative addressing modes
• Power-on Reset (POR)
• Power-up Timer (PWRT) and Oscillator Start-up Timer (OST)
• Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation
• Brown-out detection circuitry for Brown-out Reset (BOR)
• Programmable code-protection
• Power saving SLEEP mode
• Selectable oscillator options
- EC - External clock (24 MHz)
- E4 - External clock with PLL (6 MHz)
- HS - Crystal/Resonator (24 MHz)
- H4 - Crystal/Resonator with PLL (6 MHz)
• Processor clock of 24 MHz derived from 6 MHz crystal or resonator
