ATmega3209/4809 – 48-pin Data Sheet megaAVR® 0-series Introduction
The ATmega3208/3209/4808/4809 microcontrollers of the megaAVR® 0-series are using the AVR® processor with hardware multiplier, running at up to 20 MHz, with a wide range of Flash sizes up to 48 KB, up to 6 KB of SRAM, and 256 bytes of EEPROM in 28-, 32-, or 48-pin package. The series uses the latest technologies from Microchip with a flexible and low-power architecture including Event System and SleepWalking, accurate analog features and advanced peripherals. The devices described here offer Flash sizes from 32 KB to 48 KB in a 48-pin package.
Features
• AVR® CPU – Single-cycle I/O access – Two-level interrupt controller – Two-cycle hardware multiplier • Memories – Up to 48 KB In-system self-programmable Flash memory – 256B EEPROM – Up to 6 KB SRAM – Write/Erase endurance: • Flash 10,000 cycles • EEPROM 100,000 cycles – Data retention: 20 Years at 85°C • System – Power-on Reset (POR) circuit – Brown-out Detection (BOD) – Clock options: • 20 MHz low power internal oscillator with fuse-protected frequency setting • 32.768 kHz Ultra Low Power (ULP) internal oscillator • 32.768 kHz external crystal oscillator • External clock input – Single pin Unified Program Debug Interface (UPDI) – Three sleep modes: • Idle with all peripherals running and mode for immediate wake-up time • Standby – Configurable operation of selected peripherals © 2018 Microchip Technology Inc.
