SPI/QSPI Serial Flash Memory, QSPI Serial Phase Change Memory Driver

Serial Memory

Overview

This driver (sample program) uses the clock-synchronous serial I/O functions of a Renesas microcontroller to control reading, writing, and erasing of data.

  • RX Family
    • Data can be read, written, and erased simply by calling user API functions.
    • Control is possible using the following serial interfaces of the microcontroller:
    • The clock-synchronous mode of the serial communication interface (SCI) and a single port are used for control.
    • Clock-synchronous operation (three-wire) of the serial peripheral interface (RSPI) and a single port are used for control.
    • The quad serial peripheral interface (QSPI) which is set to clock-synchronous operation and a single port are used for control.
  • RL78 Family
    • Data can be read, written, and erased simply by calling user API functions.
    • The SCI mode of the serial array unit (SAU) and a single port are used for control.

RX Family (FIT module)

The software components shown in the figure below are FIT modules based on the Renesas Firmware Integration Technology (FIT). You can easily embed sample code in user applications by combining the required FIT modules. For example, you can use the DMAC or DTC FIT module to handle transfer by the DMAC or DTC. (About FIT)

RL78 Family (SIS module)

The RL78 family serial NOR flash memory control modules shown in the figure below are SIS modules based on the Software Integration System (SIS) approach. You can easily embed sample code in user applications by using such SIS modules with the Code Generator included in the Smart Configurator. For example, you can use the Code Generator to produce code for handling transfer by the RL78 family data transfer controller.
