AT25QL128A-MHE-T

Product Overview

The AT25QL128A-MHE-T from Renesas Electronics Corporation is a non-volatile NOR flash memory IC with a 128Mbit capacity and a 16M x 8 memory organization. It uses an SPI interface with Quad I/O and QPI support, and is specified for a 104 MHz clock frequency. The device operates from a 1.7V to 2V supply and is offered in an 8-UDFN exposed-pad package with the 8-UDFN (5x6) device package designation for surface-mount assembly. Its temperature range is -40°C to 85°C (TA).

Design & Procurement Notes

When selecting this device, confirm that the host controller supports the SPI - Quad I/O, QPI interface and can operate at the specified 104 MHz clock frequency. The supply rail must remain within 1.7V to 2V across the intended operating conditions, and thermal design should consider the -40°C to 85°C (TA) range. Layout should accommodate the 8-UDFN exposed-pad package and its 5x6 device package designation, including pad connections for the exposed pad. Firmware timing should also account for the 150µs word and 5ms page write cycle times when planning write and configuration operations. For procurement documentation, specify the exact part number AT25QL128A-MHE-T and the 8-UDFN (5x6) package variant.
