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

The ATMEL ATMEGA48-20PU is a high-performance, 8-bit AVR RISC-based microcontroller, offering an optimal balance of processing power and energy efficiency. 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 20MHz and an operating voltage range of 2.7V to 5.5V, it is designed for robust performance in demanding applications.

Its advanced RISC architecture executes powerful instructions in a single clock cycle, achieving throughputs approaching 1 MIPS per MHz. The core features 32 general-purpose working registers, all directly connected to the Arithmetic Logic Unit (ALU), enabling highly efficient code execution. This architecture delivers performance up to ten times faster than conventional CISC microcontrollers.
