Description
The V850ES/SG3 and V850ES/SJ3 are 32-bit single-chip microcontrollers that includes the V850ES CPU core and peripheral functions such as ROM/RAM, a timer/counter, serial interfaces, an A/D converter, and a D/A converter. The V850ES/SG3 and V850ES/SJ3 includes an IEBus ® (Inter Equipment Bus ®) controller for the automotive LAN, and some of the models also include a CAN (Controller Area Network) controller.

- Application NoteAI-generated Summary: The document details the usage of LIN and UART controllers, covering device and IP-level mapping, base addresses, memory vectors, and device adaptation. It includes application examples such as serial and graphics monitor programs, LIN communication tables, and application layer functions. The FAQ section addresses interrupt handling, status information, data reception after errors, self-test failures, and LIN conformance with specification 2.2A. It also provides terminology and issue-solving indexes for quick reference.
- Application NoteAI-generated Summary: The document details the Renesas CAN Controller's usage, including compatibility, evaluation results, and principles of pretended networking. It covers sample software descriptions, CAN driver functionalities such as initialization, configuration, transmission, reception, and diagnostics. The text also explains mapping of lower CAN drivers, application examples, and frequently asked questions addressing CAN conformance, transceiver issues, bit timing, operation modes, power save modes, transmission, reception, message storage, peripheral bus access, and interrupt handling.

- Application NoteAI-generated Summary: The document explains how to use I²C bus communication to write and read data from an external EEPROM connected to the PC bus, using a V850ES/Jx3-L microcontroller. It details writing 4-byte blocks to the EEPROM, reading them back, and comparing the data to control LEDs indicating success or failure. The sample code supports EEPROM sizes from 2 to 512 Kb, verified on a 16 Kb EEPROM. Hardware configuration, pin usage, and development environment details are also provided.Related Files:

- Application NotePDF 1.41 MB R01AN1131EU0101 Rev.1.01 Mar 31, 2012AI-generated Summary: Flash memory protection in 78K0, 78K0R, RL78, and V850 devices involves multiple independent security features for different access modes: serial programming, debugging, self-programming, and normal operation. Protection flags control chip erase, block erase, programming, reading, and boot block reprogramming. These flags prevent unauthorized erasure, programming, or reading via external tools but do not restrict self-programming except for boot blocks. Debugging access requires password authentication, and some devices allow complete debug interface disablement. Security settings can be configured using dedicated programmers or self-programming, with various levels of protection to secure application code.

Security code overwritten in V850ES/SJ3 - μPD70F3358
I happened to overwrite the security code area (0x70 to 0x7A. By default 0xffff....ff) with my application code after wrongly modifying the linker directive file.If I try flashing again, my debugger ID850QB asks for the security code in this area, and I dont what is in there.So ...
