AVR® EA MCUs
Microchip's AVR EA MCUs enable reliable sensor interfaces in harsh environments
Microchip's AVR EA family, with its powerful AVR CPU, integrated analog, and Core Independent Peripherals (CIPs), enables users to build compact designs with built-in flexibility and lower system cost.
Microchip equipped the AVR EA family of microcontrollers (MCUs) with high-speed integrated analog, hardware-based CIPs, and low-power performance for efficient real-time control, sensor node, and secondary safety monitoring applications.
For design flexibility and to optimize board layout, Microchip offers this family of 16 KB to 64 KB Flash devices in SPDIP, SSOP, TQFP, and VQFN packages ranging from 28 pins to 48 pins. These AVR EA MCUs are well suited for a wide range of industrial, consumer, appliance, automotive, sensor node, and other applications. The AVR EA family of MCUs is a great option for closed-loop control system designs and secondary monitoring devices for safety reasons.
- Up to 64 KB Flash with true read-while-write (RWW) operation
- Internal 20 MHz oscillator
- External high-frequency crystal oscillator (XOSCHF) with clock failure detection (CFD)
- 375 ksps 12-bit differential and single-ended analog-to-digital converter (ADC)
- Programmable gain amplifier (PGA) supporting up to 16x gain
- 10-bit digital-to-analog converter (DAC)
- Two analog comparators with window compare functions and scalable reference input
- Cyclic redundancy check (CRC) scan
- Six 16-bit timer/counters
- 16-bit real time clock (RTC) and periodic interrupt timer (PIT)
- Configurable custom logic (CCL) peripheral
- Six-channel peripheral event system
- Configurable, internally generated reference voltage
- Three USARTs, one SPI, one dual-mode TWI
