Components

Microchip 256-Kbit (32K x 8) I2C non-volatile serial EEPROM IC with 400kHz Fast-mode I2C, 64-byte page write, and 1,000,000 write cycle endurance.

Microchip/Atmel 32-Kbit (4K x 8) I2C serial EEPROM IC operating from 1.7V to 5.5V, commonly integrated on DS3231 RTC breakout modules for persistent logging.

Generic MicroSD card breakout module featuring SPI communication, onboard 3.3V LDO regulator, and 5V-to-3.3V level shifter IC for datalogging with 5V or 3.3V microcontrollers.

Winbond 32-Mbit (4MB) SPI NOR serial flash memory IC featuring Dual/Quad SPI clock rates up to 104 MHz (208/416 MHz equivalent), 100,000 erase/program cycles, and 20-year data retention.
