• 130 powerful instructions
• 32 × 8 general purpose working registers
• Fully static operation
• Up to 16MIPS throughput at 16MHz
• On chip 2 cycle multiplier
• High endurance non volatile memory segments
• 8Kbytes of in system self programmable flash program memory
• 512bytes EEPROM
• 1Kbyte internal SRAM
• Write/erase cycles: 10,000 flash/100,000 EEPROM
• Data retention: 20 years at 85°C/100 years at 25°C(1)
• Optional boot code section with independent lock bits
• In system programming by on chip boot program
• True read-while-write operation
• Programming lock for software security
• Two 8-bit timer/counters with separate prescaler, one compare mode
• One 16-bit timer/counter with separate prescaler, compare mode, and capture mode
• Real time counter with separate oscillator
• Three PWM Channels
• Byte oriented two-wire serial interface
• Programmable serial USART
• Serial peripheral interface (SPI)
• Programmable watchdog timer with separate on chip oscillator
