DESCRIPTION

· The ATmega48A/PA/88A/PA/168A/PA/328/P is a low-power, CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture.

· It achieves high CPU throughput by executing instructions in a single clock cycle, optimizing power consumption versus processing speed.

FEATURES

· High-performance, low-power AVR® 8-bit microcontroller family with advanced RISC architecture.

· 131 powerful instructions, most executing in a single clock cycle, with up to 20 MIPS throughput at 20MHz.

· 32 x 8 general-purpose working registers and fully static operation.

· On-chip 2-cycle multiplier and high-endurance non-volatile memory segments.

· In-system self-programmable Flash program memory, EEPROM, and internal SRAM with high write/erase cycles and data retention.

· Optional boot code section with independent lock bits and in-system programming by on-chip boot program.

· QTouch® library support for capacitive touch buttons, sliders, and wheels with up to 64 sense channels.

· Peripheral features include two 8-bit and one 16-bit Timer/Counters with separate prescaler, compare mode, and capture mode.

APPLICATIONS

· Suitable for applications requiring low power consumption and high processing speed.

· Ideal for systems needing in-system self-programmable memory and high-endurance non-volatile memory.

· Applications requiring capacitive touch sensing and advanced timer/counter functionalities.
