产品概述

• 产品概述

  AVR64EA28-I/SS is a microcontroller of the AVR® EA Family using the AVR® CPU with hardware multiplier running at clock speeds up to 20MHz. It come with 64KB of flash, 6KB of SRAM, and 512bytes of EEPROM. The AVR® EA Family uses the latest technologies from Microchip with a flexible and low-power architecture, including event system, accurate analogue subsystems, and advanced digital peripherals.

  • AVR® CPU, running at up to 20MHz, single-cycle I/O register access
  • 64KB In-system-programmable flash memory with a true read-while-write operation
  • Power-on Reset (POR) circuit, brown-out detector (BOD) with user-programmable levels
  • High-precision internal oscillator with selectable frequency up to 20MHz (OSCHF)
  • Single pin unified program and debug interface (UPDI)
  • Three USARTs with fractional baud rate generator, auto-baud, and start-of-frame detection
  • Event system for CPU-independent and predictable inter-peripheral signalling
  • Watchdog timer (WDT) with window mode and separate on-chip oscillator
  • 28-SSOP package, 1.8 to 5.5V supply voltage
  • Temperature rating range from -40°C to +85°C
