Description

[Code Examples](https://mplab-discover.microchip.com/v2/category/com.microchip.code.examples?dsl=avr64ea48) The AVR32EA48 is a microcontroller in the AVR® EA family featuring the AVR® CPU with hardware multiplier, running at up to 20 MHz and with 32 KB Flash with dedicated Read-While-Write (RWW) section, 4 KB SRAM and 512B of EEPROM available in 48-pin VQFN and TQFP packages. The family uses the latest Core Independent Peripherals with low-power features including Event System, intelligent analog and advanced peripherals. The new 12-bit ADC offers true differential measuring capabilities with optional hardware accumulation of up to 1024 samples, which effectively gives up to 17-bits resolution. With sampling rates up to 375 ksps the analog data is available very rapidly. The Programmable Gain Amplifier (PGA) for the ADC can amplify single-ended and differential analog inputs to make it possible to measure even small amplitude signals efficiently. **Functional Safety** This product is suitable for [safety-critical applications](https://www.microchip.com/design-centers/8-bit/functional-safety) that target home appliances (IEC 60730), automotive (ISO 26262) and industrial (IEC 61508) products. We have important documentation and tools available to aid developers of safety applications—refer to the product feature list for links to the specific safety collateral. TÜV SÜD-certified MPLAB® X Integrated Development Environment (IDE) tools, such as the [MPLAB XC8 Functional Safety Compiler](https://www.microchip.com/developmenttools/ProductDetails/SW006021-FS), are also available for this product.
