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.
Flash
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.
