High-Performance RISC CPU:
• Only 33 single word instructions to learn
• All instructions are single cycle except for pro-
gram branches which are two-cycle
• Operating speed: DC - 40 MHz clock input
DC - 100 ns instruction cycle
12-bit wide instructions
• 8-bit wide data path
• Seven or eight special function hardware registers
• Two-level deep hardware stack
• Direct, indirect and relative addressing modes for
data and instructions
Peripheral Features:
• 8-bit real time clock/counter (TMR0) with 8-bit
programmable prescaler
• Power-on Reset (POR)
• Device Reset Timer (DRT)
• Watchdog Timer (WDT) with its own on-chip
RC oscillator for reliable operation
• Programmable Code Protection
• Power saving SLEEP mode
• Selectable oscillator options:
- RC: Low cost RC oscillator
- XT: Standard crystal/resonator
- HS: High speed crystal/resonator
- LP: Power saving, low frequency crystal
CMOS Technology:
• Low power, high speed CMOS EPROM/ROM tech-
nology
• Fully static design
• Wide operating voltage and temperature range:
- EPROM Commercial/Industrial 2.0V to 6.25V
