Overview

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.

  • 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.
  • Application Examples：
    • Mobile phones/Cordless phones/Fax machine: Abbreviated dialing systems/Communication History Administration
    • TV/VCR/Remote Control; Channel, Mode setting
    • Measurement devices: Application Software, Log data storage
    • Home telephones: Fine adjustment setting, usage status history administration
    • LCD TV: Parameter settings
    • Camera modules: Adjustment settings
    • DVC: Adjustment settings

RX Family (FIT module)

The following software is a FIT module, i.e. within our FIT range, so it can easily be combined with other FIT modules. For example, transfer by a DMAC or DTC can easily be handled by combining this module with a DMAC or DTC module, both of which are currently available within our FIT range. (About FIT)
