MB85RSXX is a FeRAM (Ferroelectric Random Access Memory) chip, using the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile memory cells. MB85RSXX adopts the Serial Peripheral Interface (SPI). The MB85RSXX is able to retain data without using a back-up battery, as is needed for SRAM. The memory cells used in the MB85RSXX can be used for 10^10 read/write operations, which is a significant improvement over the number of read and write operations supported by Flash memory and E2PROM. MB85RSXX does not take long time to write data like Flash memories or E2PROM, and MB85RSXX takes no wait time.
LibDriver MB85RSXX is a full-featured driver for MB85RSXX, launched by LibDriver. It provides writing, reading and additional features. LibDriver is MISRA compliant.
/src includes LibDriver MB85RSXX source files.
/interface includes LibDriver MB85RSXX SPI platform independent template.
/test includes LibDriver MB85RSXX driver test code and this code can test the chip necessary function simply.
/example includes LibDriver MB85RSXX sample code.
/doc includes LibDriver MB85RSXX offline document.
/datasheet includes MB85RSXX datasheet.
/project includes the common Linux and MCU development board sample code. All projects use the shell script to debug the driver and the detail instruction can be found in each project's README.md.
/misra includes the LibDriver MISRA code scanning results.
Reference /interface SPI platform independent template and finish your platform SPI driver.
Add the /src directory, the interface driver for your platform, and your own drivers to your project, if you want to use the default example drivers, add the /example directory to your project.
You can refer to the examples in the /example directory to complete your own driver. If you want to use the default programming examples, here's how to use them.
