WriteNow! supports the new Renesas RH850/U2A Cross-Domain MCUs
This month Algocraft‘s Technical Team decided to focus on a recently introduced development: it is the support on the WriteNow! platform of a new series of MCUs dedicated to new generations of automotive applications.
RH850/U2A MCU is the first member of Renesas’ cross-domain MCUs, a new generation of automotive-control devices; it is designed to to increase the integration of multiple applications on a single chip, enabling the realization of unified electronic control units (ECUs) for the evolving electrical/electronic architecture (E/E architecture).
Algocraft has developed a programming algorithm that manages various new functionalities, including programming of FLASH areas, User Boot, Data, Configuration & Security Settings, Block Protections, and the Authentication ID-Code.
The programming protocol used is the serial asynchronous SCI, which can reach speeds of up to 10MBits/s. For a 16MB memory cut, the overall programming time, including checksum verification, is approximately 35 seconds.
Algorithm’s characteristics:
CSI 3-wire protocol based on Renesas
specifications. Commands for ID authentication, configuration and security settings.
R7F702300 (16MB FLASH, CSI @10MHz) – erase + blank check + program + verify checksum: 35s
WriteNow! is ideal for multi-panel boards applications being able to handle up to 32 boards by using only one programming unit.
Algocraft’s staff and their selected worldwide distributor network are ready to analyse and discuss with you your specific programming application.
