ATTINY424-SSFR General Description

The ATtiny424 is a microcontroller featuring the AVR®  CPU with hardware multiplier, running at up to 20 MHz and with 4 KB Flash, 512B SRAM and 128B of EEPROM in 14-pin TSSOP and SOIC packages. The family uses the latest Core Independent Peripherals with low-power features, including an 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 are 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.
