Renesas Part Number Reference

MPN Structure Overview

Renesas part numbers follow structured formats that vary by product family. The main MCU families are:

  • RL78: 8/16-bit low-power MCUs (R5F1xxxx)
  • RX: 32-bit general purpose MCUs (R5Fxxxxx)
  • RA: 32-bit Arm Cortex-M MCUs (R7FAxxxx)
  • RH850: 32-bit automotive MCUs (R7F7xxxx)
  • R8C: 16-bit compact MCUs (R5Fxxxx)

Handler Implementation Notes

Current RenesasHandler Issues

  1. HashSet Usage: Uses 
    new HashSet<>()
    instead of 
    Set.of()
    - mutable set returned
  2. Package Extraction Logic: Simple algorithm finds last digit and takes everything after it
    • Works for patterns like 
      R5F51303ADFN
      -> 
      DFN
    • May fail for complex suffixes with version numbers

Pattern Registration

The handler registers patterns for:

  • RX Series: 
    ^R5F[0-9]+.*
  • RL78 Series: 
    ^R5F1[0-9]+.*
  • RH850 Series: 
    ^R7F[0-9]+.*
  • RA Series: 
    ^R7FA[0-9]+.*
  • R8C/RE Series: 
    ^R8C[0-9]+.*
  • Memory: 
    ^R1EX[0-9]+.*
    , 
    ^R1LV[0-9]+.*

Overlapping Patterns Issue

Note: RL78 pattern 

^R5F1[0-9]+.*
is a subset of RX pattern 
^R5F[0-9]+.*
This means RL78 parts will match both patterns.

Supported ComponentTypes

ComponentType.MICROCONTROLLER
ComponentType.MICROCONTROLLER_RENESAS
ComponentType.MCU_RENESAS
ComponentType.MEMORY
ComponentType.MEMORY_RENESAS

Series Extraction Logic

Current implementation:

  • R5F1xxx
    -> "RL78"
  • R5Fxxx
    (not R5F1) -> "RX"
  • R7FA
    -> "RA"
  • R7F
    (not R7FA) -> "RH850"
  • R8C
    -> "R8C"
  • R1EX
    -> "Flash"
  • R1LV
    -> "Low Voltage"
