Description

The Spansion VG037CHXT is a flash non-volatile memory product that utilizes MirrorBit technology and Eclipse architecture. It is built on a 65 nm process lithography and is part of the S25FL family of devices. This model connects to a host system through a Serial Peripheral Interface (SPI) and supports single bit serial input/output (SIO), optional two-bit (DIO), and four-bit (QIO) serial commands. It also incorporates Double Data Rate (DDR) read commands for faster data transfer. The Eclipse architecture in the VG037CHXT features a Page Programming Buffer that allows for faster programming and erase operations. With its high density and fast performance, this model is ideal for code shadowing, Execute-In-Place (XIP), and data storage in various embedded applications.
