The AVR16EA28 is a microcontroller in the AVR® EA family featuring the AVR® CPU with hardware multiplier, running at up to 20 MHz and with 16 KB Flash with dedicated Read-While-Write (RWW) section, 2 KB SRAM and 512B of EEPROM available in 28-pin SPDIP, SSOP, and VQFN 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.
