Psram controller IP

This controller supports AP Memory’s UHS series of high speed PSRAM devices which can clock frequencies of upto 1066 MHz.
This controller enables smooth integration of APMemory’s UHS OPI PSRAM memory device chips into various new-gen devices made with mobile and wearable low power SoCs’.
This memory controller implementation is designed to give the user full flexibility for driving the memory control signals and timing adjustment for data sampling.

This controller supports AP Memory’s Xccela open standard Bus for digital interconnect and data communications, suitable for non-volatile and volatile memories such as PSRAM.

DFSPI – SPI FLASH Controller with Execute in place – XIP (SINGLE, DUAL and QUAD SPI Bus Controller with DDR / DTR support and optional AES Encryption) + … NOR & NAND Flash Memory Support

The Octal SPI Memory Controller IP core is a serial peripheral interface (SPI) master which controls an external serial device, usually an industry-standard FLASH or PSRAM memory device.
In Software Mode, an AHB Master may access the register interface of the Controller to implement a wide range of protocol variants and/or commands on the SPI bus.

The PHYIOs is used to transfer the Command/Address/Clk and Data between the memory controller PHY and the PSRAM device
The TX is designed to send information from PHY to PSRAM and RX is designed to receive information which is from PSRAM
there are bi-direction DQ IO, TX-only CK IO, filler cell with differrent size and VDDQ/VSS power clamp IO included in the PHYIOs.

The GMC (General Memory Controller) includes two memory controllers: The NOR/PSRAM memory controller, The Synchronous DRAM (SDRAM/Mobile LPSDR SDRAM) controller

The xSPI/PSRAM master IP is easy to use, simple to work with, quick to operate, and reliable under all conditions. It supports the xSPI JESD~251 standard from a standard AXI3 or AXI4 slave interface.
It also supports APMemory Octal/QSPI RAM, HyperRAM, HyperFlash, and features backwards compatibility support for Octal SPI, QSPI, DSPI, and SPI interfaces.

SLL’s unified xSPI Multiple Bus Memory Controller IP supports the widest range of JEDEC xSPI and xSPI-like NOR Flash and PSRAM memories (JEDEC xSPI Profile 1.0 and 2.0, HyperBus 1.0, 2.0 and 3.0, OctaBus and Xccela Bus) that are available now from many memory vendors.
JEDEC xSPI and xSPI-like memories offer good performance with lower hardware and power costs. Memory device variants offer up to 512 Mbit PSRAM, up to 2 Gigabit NOR Flash, up to 250 MHz DDR clock speeds, with x4, x8 and x16 data path widths, and a wide range of package options including 4mm x 4mm BGA49 and tiny WLCSP footprints. Some PRSAM devices are now also available with internal ECC.

The JESD251 Expanded Serial Peripheral Interface Slave controller is provides high data throughput, low signal count, and limited backward compatibility with legacy Serial Peripheral Interface(SPI) devices
It is used to connect xSPI Master devices in computing, automotive, Internet of Things, Embedded system and mobile system processor to non-volatile memories, graphics peripherals, networking peripherals,FPGAs, sensors devices
