ATMEGA48P-20AU Description

Short technical summary and product information.

The ATmega48P/V/88P/V/168P/V series microcontrollers from Microchip Technology (formerly Atmel) are based on the AVR enhanced RISC architecture. These low-power, CMOS devices execute instructions in a single clock cycle, achieving high CPU throughput.

 

Key features include up to 20 MIPS throughput at 20 MHz, 16KB of self-programmable Flash program memory, 512 Bytes of EEPROM, and 1KB of internal SRAM. The microcontrollers support advanced RISC architecture with 131 powerful instructions and an on-chip 2-cycle multiplier.

 

Peripheral features include multiple timer/counters, PWM channels, a 10-bit ADC, programmable serial USART, SPI, and I2C interfaces. They also offer various sleep modes for power optimization, including Idle, Power-save, and Power-down modes.

 

Available in packages such as 28-pin PDIP, 32-lead TQFP, and 28/32-pad QFN/MLF, these microcontrollers operate within a voltage range of 1.8V to 5.5V and a temperature range of -40°C to 85°C.
