WriteNow! programmer expands the device list by adding Cypress S6J32xx series of the Traveo Family of 32-bit ARM Cortex-R5F Automotive Microcontrollers.
S6J32xx series of the Traveo family delivers state-of-the-art 2D and 3D graphics, which Cypress has optimized to bring sophisticated and automotive specific graphics functions into the car without increased power and BOM requirements.
The Traveo family includes two types of flash memories: TCM flash (TCFLASH) and work flash (WorkFlash). TCFLASH is a flash memory to mainly store programs for Traveo family. WorkFLASH is rewritable, non-volatile data memory for Traveo Family. In particular the S6J32EELT device contains 4160KB/4MB of TCFLASH and 112KB of WorkFlash.
The S6J3200 series has JTAG ports to connect with a programmer or a debugging tool. The JTAG interface integrates a Security Checker module for device security.
The WriteNow! technology allows the programming of up to 8 devices at once, drastically reducing programming times, costs, and system complexity. In addition, the WriteNow! technology performances allow to reach the theoretical programming speed for any given device, thus shortening as much as possible the programming phase of the production process.
For Traveo devices, WriteNow! uses the standard JTAG protocol as programming interface.
The programming algorithm allows to enter the device 128-bit security keys in order to lock/unlock the device via JTAG interface.
Algocraft provides support of Cypress Traveo family to the whole WriteNow! Series, single and parallel in-system programmers. Four models are available: WN-PRG01A (programs 1 device at a time), WN-PRG02A (programs 2 devices in parallel), WN-PRG04A (programs 4 devices in parallel), and WN-PRG08A (programs 8 devices in parallel).
In addition, external demultiplexer modules are available as accessories for multiple-site WriteNow! models, giving the flexibility to program up to 32 devices in easy way.
The complete programming time for S6J32EEL device (4MB TCFLASH, JTAG @15MHz) included the program and verify of the whole memory size is about 45 seconds.
The chip erase time is about 30s.On device blank condition the chip erase time is less then 1s.
