Overview
Description
This driver controls Renesas serial EEPROM products that employ the latest memory technology to deliver low-voltage operation, low power consumption, high-speed operation, and high reliability. The driver is configured to work with the industry-standard bus of the serial EEPROM.
Features
- Data can be read and written simply by calling user API functions.
- The clock-synchronous serial I/O function of the microcontroller 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)
The RX Driver Package provides the set of FIT modules. Obtain the package, and you can then download the set of FIT modules you require. Furthermore, FIT modules work in combination with the Smart Configurator, which eases both downloading of the FIT modules and embedding them in user applications.
