Atmel ATmega48PA/ATmega88PA AVR Microcontroller Handbook
This handbook describes the ATmega48PA and ATmega88PA low‑power 8‑bit AVR microcontrollers. It outlines the core architecture, instruction set, and peripheral features such as timers, ADCs, USART, SPI, and watchdog timer. The document also includes a block diagram, pin‑out diagrams, and detailed pin descriptions.
Additional sections cover memory sizes (Flash, EEPROM, SRAM), operating voltage and temperature ranges, power‑consumption figures, and reliability data. Resources for development tools, code examples, and contact information for Atmel support are also provided.
