It operates from a single supply between 1.65 V and 3.6 V. The memory is non-volatile, formatted as FLASH, and rated for the industrial temperature range of -40°C to 85°C. ## Package and footprint Housed in an 8-UDFN with an exposed pad (supplier package 8-UDFN 5x6), the part is surface-mount and requires a thermal pad connection on the PCB for heat dissipation during sustained write cycles. The exposed pad also improves mechanical stability in vibration-prone environments.","metaTitle":"AT45DB021E-MHN2B-T 2Mbit SPI Flash, 70 MHz, 8-UDFN","metaDescription":"AT45DB021E-MHN2B-T 2Mbit SPI Flash from Microchip. 70 MHz clock, 1.65V-3.6V supply, -40°C to 85°C.
