iCorp Group recently signed an agreement with Winbond for official distributorship in southern Africa. Winbond is a specialty memory IC company engaged in design, manufacturing and sales services, with major product lines including code storage Flash memory, specialty DRAM and mobile DRAM.
Winbond’s W25X and W25Q SpiFlash multi-I/O memories feature the popular serial peripheral interface (SPI), densities from 512 Kbit to 512 Mbit, small erasable sectors and high performance. The W25X family supports Dual-SPI, effectively doubling standard SPI clock rates. The W25Q family is a superset of the 25X family with Dual-I/O and Quad-I/O SPI for even higher performance.
Clock rates up to 104 MHz achieve an equivalent of 416 MHz (50 MBpS transfer rate) when using Quad-SPI. This is more than eight times the performance of ordinary serial Flash (50 MHz) and even surpasses asynchronous parallel Flash memories while using fewer pins and less space. Faster transfer rates mean controllers can execute code (XIP) directly from the SPI interface or further improve boot time when shadowing code to RAM. Additionally, some SpiFlash devices offer the new quad peripheral interface (QPI) supporting true quad commands for improved XIP performance and simpler controller circuitry. Additionally, new ultra-small form factor packages are ideal for space constrained mobile and handheld applications.
Winbond TS16949 certified AEC-Q100 qualified memories now support automotive applications. Digital displays in automotive dashboards provide more information about the car, and improve safety. Instant-on and real-time 2D/3D image rendering is achieved with fast processors and SpiFlash memories. ADAS (advanced driver assist systems), comfort, entertainment and navigation are now available in the centre console, and this is addressed with SpiFlash memories using small packages for space constrained systems and high density for advanced applications.
