54SXxx - General Purpose SDRAM Controller

Download the 54SXxx datasheet PDF. This datasheet also covers the 54SX08 variant, as both devices belong to the same general purpose sdram controller family and are provided as variant models within a single manufacturer datasheet.

General Description

This is the system clock.

The controller can transfer data at this rate during bursts.

This is a reset signal.

v2.0 General-Purpose SDRAM Controller SD R A M Co n t r o l l er Fu nc t i o na l D es cr i p t i o n The general-purpose SDRAM controller is designed to provide simplified control of many different sizes of SDRAMs. The controller architecture provides control for data bursts by linearly incrementing the address. The user starts a burst at a specified address and the burst continues until the user terminates it.
