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 AVR® 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
• QTouch® library support
– Capacitive touch buttons, sliders and wheels
– QTouch and QMatrix® acquisition
– Up to 64 sense channels
• Peripheral Features
– Two 8-bit Timer/Counters (TC) with separate prescaler and compare mode
– 16-bit Timer/Counter with separate prescaler, compare mode, and capture mode
– Real Time Counter (RTC) with separate oscillator
– Six Pulse Width Modulation (PWM) channels
– 8-channel 10-bit Analog-to-Digital converter (ADC) with temperature measurement
– Programmable serial USART with start-of-frame detection
