Minimum requirements

The Renesas RA4M3 series devices requires special handling for the TrustZone partition registers of the MCU. This requires certain HW support which is not provided by older J-Link models. The following table lists the minimum J-Link HW version needed to support this MCU.

  • J-Link-OB-S124
  • J-Link BASE V10
  • J-Link PLUS V10
  • J-Link ULTRA+ V4
  • J-Link PRO V4
  • J-Link WiFi V1
  • J-Trace PRO V2 Cortex-M
  • J-Trace PRO V2 Cortex

Later versions (e.g. V10 is listed and current HW is V11) will also work.

Note: Models which are not listed here do not support this MCU.


Internal option-setting memory

Option-settings memory is located at 0x0100A100 has a size of 512 Bytes.

Internal program flash

The size of the program flash is dependent on the device used.

Device Size (KiB) Memory region
R7FA4M3AD 512 0x00000000 - 0x0007FFFF
R7FA4M3AE 768 0x00000000 - 0x000CFFFF
R7FA4M3AF 1024 0x00000000 - 0x000FFFFF
Currently only single bank flash operations are supported. Dual bank mode is not supported.

Internal data flash

Internal data flash is located at 0x08000000 has a size of 8 KB.

External QSPI flash

External QSPI flash is located at 0x60000000.

Supported pin configurations

QSPI flash programming requires special handling compared to internal flash. For more information about this, please see the QSPI Flash Programming Support article.
