ATMEGA48PA-PU Description

Short technical summary and product information.

ATMEGA48PA-PU is an 8-bit AVR microcontroller from Microchip Technology (formerly Atmel). It is based on the enhanced RISC architecture and executes most instructions in a single clock cycle, delivering up to 20 MIPS at a 20MHz maximum clock frequency.

 

The device integrates 4KB of in-system self-programmable flash memory, 512B SRAM, and 256B EEPROM. On-board peripherals include two 8-bit timers/counters, one 16-bit timer/counter, six PWM channels, a six-channel 10-bit ADC, and a real-time counter with separate oscillator. Communication is supported through a programmable USART, master/slave SPI, and a byte-oriented 2-wire serial interface (I2C).

 

The microcontroller operates from 1.8V to 5.5V and is specified over a -40°C to +85°C temperature range. Power consumption is low, with typical active current of 0.2mA at 1MHz and 0.1µA in power-down mode, making it suitable for battery-powered applications. It is available in a 28-pin PDIP through-hole package.
