ATmega48PB/88PB/168PB
AVR Microcontroller with Core Independent Peripherals
and PicoPower technology
Introduction
ATmega48PB/88PB/168PB is a low-power CMOS 8-bit microcontroller based on the AVRВ® enhanced
RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega48PB/88PB/
168PB achieves throughputs approaching 1MIPS/MHz, allowing the system designer to optimize power
consumption versus processing speed. Features Advanced RISC architecture
– 131 instructions – most single clock cycle execution
– 32 x 8 general purpose working registers
– Fully static operation
– Up to 20MIPS throughput at 20MHz
– On-chip 2-cycle Multiplier
High endurance non-volatile memory segments
– 4/8/16KBytes of in-system self-programmable Flash program memory
– 256/512/512Bytes EEPROM
– 512/1K/1KBytes internal SRAM
– Write/Erase cycles: 10,000 Flash/100,000 EEPROM
– Data retention: 20 years at 85°C/100 years at 25°C
– Optional boot code section with independent lock bits In-system programming by on-chip boot program True Read-While-Write (RWW) operation
– Programming lock for software security
QTouchВ® library support
– Capacitive touch buttons, sliders and wheels …
