WriteNow! programmer expands the device list by adding many new Renesas devices (+100), part of the RH850 Family (Automotive target) of 32-bit single-chip microcontroller with a G3K core.

The RH850 is Renesas Electronics' latest automotive micro-controller family that offers high performance balanced with very low power consumption over a wide and scalable range of products. This family offers rich functional safety and embedded security features needed for new and advanced automotive applications.

As programming interface, WriteNow! uses the standard UART  protocol with a maximum Baudrate of 2000000 bits/s.

Algocraft provides support of Renesas RH850 family through all of its WriteNow! Series, single and parallel In-System Programmers. Our four WN programmers are: WN-PRG01A (programs 1 device by one), WN-PRG02A (programs 2 devices in parallel), WN-PRG04A (programs 4 devices in parallel), and WN-PRG08A (programs 8 devices in parallel).

In addition, we provide external Demultiplexer modules as accessories for the multiple-sites WriteNow! models, able to extend the programming channels up to 32 in a sequential way (8+8+8+8).

Thanks to the optimized WriteNow! architecture, the typical programming time for R7F701010 device - RH850/F1L Group (512KB Flash and 32KB Data) is about 8 seconds (program + verify). The complete programming cycle included the chip erase, blank check, program and verify with readout method of the whole memory (Code and Data) size is about 11s.

WriteNow! Technology allows to program up to 8 devices at once, drastically reducing programming times, costs, and system complexity. In addition, WriteNow! Technology’s performances allow to achieve the theoretical programming speed for any given device, thus shortening as much as possible the programming phase of the production process.
