ATTINY1627-MF 8-bit ATtiny AVR-RISC microcontroller, 16 KB, 20 MHz, VQFN-24

ATTINY1627, tinyAVR® 2 Family

Description The ATtiny1627 is a microcontroller featuring the AVR® CPU with hardware multiplier, running at up to 20 MHz and with 16 KB Flash, 2 KB SRAM, and 256B EEPROM in a 24-pin VQFN 4 x 4 mm package. 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.
