Atmel ATMEGA48-20PU 8-Bit Microcontroller DIP28 4KB Flash

Atmel ATMEGA48-20PU 8-Bit Microcontroller DIP28 4KB Flash is an 8-bit AVR RISC-based microcontroller in a DIP28 package, offering a balance of processing power and energy efficiency with 4KB of in-system programmable flash memory.

It combines 4KB of in-system programmable (ISP) flash memory, 512B of SRAM, and 256B of EEPROM for reliable data storage. With a throughput of 20 MIPS at 20 MHz and an operating voltage range of 2.7V to 5.5V, it is designed for robust performance in demanding applications.

The advanced RISC architecture executes instructions in a single clock cycle, with throughput approaching 1 MIPS per MHz. The core provides 32 general-purpose working registers, all directly connected to the Arithmetic Logic Unit (ALU), which supports efficient code execution.
