Winbond Electronics maintains its competitiveness in the SPI NOR Flash field through a variety of innovative technologies, driving the development of storage technology. Its 1.2V SPI NOR Flash product, the W25Q64NE, operates at a voltage range of 1.14V to 1.6V. Compared to 1.8V products, it can reduce operating power consumption by about one-third, thereby significantly enhancing the battery life of devices. From the perspective of high-efficiency technology, Winbond supports a variety of SPI clock rates with a maximum speed of up to 166MHz. For example, the W25Q512NW supports high-speed reading at 166MHz SDR and 80MHz DDR, as well as QPI mode, which meets the needs of XIP and real-time booting. In terms of small-size packaging technology, Winbond offers mature KGD solutions, with 8Mb flash products featuring high read speeds and smaller form factors, enhancing the value of embedded systems. The high-reliability technology is reflected in the 46nm process of QspiNAND Flash, which has a data retention period of up to 10 years, and built-in error correction code circuits ensure data integrity. The SpiStack® technology enables different die combinations to be stacked within a standard package, improving integration and performance. In terms of security features, the secure flash product series includes hardware lock control functions and OTP security registers, enhancing data protection. Regarding product compatibility, the entire series of SPI NOR flash products are pin-compatible with each other. For example, the W25Q512NW allows customers to easily upgrade capacity without modifying the PCB design, saving development time and effort.
The W25Q256JVCIM is a 256M-bit (32M x 8) SPI NOR Flash memory, available in a 24-TFBGA (6x8) package. It operates at a voltage range of 2.7V to 3.6V and supports a standard SPI clock frequency of up to 133MHz. With dual/quadruple I/O, the equivalent frequency can reach up to 532MHz. It can reliably operate within a temperature range of -40°C to 85°C. It features 4KB sector partitioning, supporting flexible 4K/32K/64K byte sector/block erase operations, with a page write time of 3ms and a block erase time of 2s (64KB). The data retention period exceeds 20 years. It includes software and hardware write protection, three 256-byte OTP security registers, and supports standard SPI, dual SPI, quad SPI, and QPI interfaces. It is widely used in industrial control, automotive electronics, IoT, and consumer electronics, meeting the needs for high reliability, wide temperature range, and efficient data management.
In the automotive electronics field, the W25Q256JVCIM has a wide range of applications. It is suitable for in-vehicle infotainment systems (such as center console entertainment and navigation systems), smart cockpits (such as full digital instrument panels and HUD), driving assistance systems (such as ADAS and camera sensors), body control modules (such as ECU and micro-motor control), and electric vehicle power systems (such as BMS and motor control). Its 256M-bit large capacity, high-speed reading capability of up to 133MHz, wide voltage range of 2.7V to 3.6V, industrial-grade temperature range of -40°C to 85°C, page write time of 3ms, and block erase time of 2s ensure fast data loading and long-term stable storage. Additionally, it supports software and hardware write protection and three 256-byte OTP security registers, enhancing data security and preventing data tampering and unauthorized access. These features make the W25Q256JVCIM an ideal storage solution for automotive electronics.
