AT25FF041A-UUN-T

Product Overview

The AT25FF041A-UUN-T is a Renesas Electronics Corporation non-volatile FLASH memory IC based on NOR technology. It provides 4Mbit of storage organized as 2M x 2 and uses an SPI - Quad I/O interface with a 104 MHz clock frequency. The device uses an 8-XFBGA, WLCSP package with 8-WLCSP (1.77x1.74) dimensions and surface-mount construction. It operates from a 1.65V to 3.6V supply and is specified for an operating temperature range of -40°C to 85°C (TC).

Key Features

• 4Mbit non-volatile FLASH memory using NOR technology
• 2M x 2 memory organization
• SPI - Quad I/O serial memory interface
• 104 MHz clock frequency
• 22µs word write cycle time and 2.6ms page write cycle time
• 1.65V to 3.6V supply voltage range
• -40°C to 85°C (TC) operating temperature range
• 8-XFBGA, WLCSP surface-mount package with 8-WLCSP (1.77x1.74) dimensions

Applications

• Embedded firmware or boot code storage in systems using an SPI host controller
• Non-volatile parameter and configuration retention in compact surface-mount assemblies
• Lookup table storage for embedded processing where NOR FLASH access and SPI - Quad I/O are compatible with the host interface

Design & Procurement Notes

When selecting this device, confirm that the host controller supports SPI - Quad I/O and is compatible with the 104 MHz clock frequency. The 1.65V to 3.6V supply range should be matched to the system rail, and the -40°C to 85°C (TC) temperature range should be checked against the intended thermal conditions. The 8-WLCSP (1.77x1.74) package requires surface-mount assembly and footprint planning. The 22µs word and 2.6ms page write cycle times should be considered for firmware update or configuration write timing. For procurement planning, confirm the exact part number AT25FF041A-UUN-T and package footprint.
