NXP

eFuses are OTP (One-Time Programmable) memory and can be used for several purposes.

This Technical Note describes how to read or write eFuses on NXP S32S2xx Microcontroller Family using Python script. A Python script example is attached to this document.

 
Renesas RH850

This Technical Note describes how to program Security Setting Area (SSA) on RH850/U2x devices via Python scripts.

Please read the general topic on RH850/U2x: Hardware Property Area programming first.

 

Intelligent Cryptographic Unit Master (ICUM) is a RH850 HSM core that can run custom cryptographic operations. The ICUM core is disabled at device shipment.

This Technical note describes how to enable and disable ICUM core on RH850 devices using Python scripts. Python script examples are attached to this document.

Supported: F1KM, F1KH, P1HC, F1H

 

A debug access security level can be raised by using ID code authentication and Challenge-Response (C&R) authentication. When the security level is raised all cores are locked for debug.

This Technical note describes how to enable PE and ICUM debugging using Python scripts, when the Challenge & Response Authentication is enabled. Python Scripts are attached to this document.

Supported: F1KM, F1KH, P1HC, F1H
