![]() Overall, the benefits of 1.2V Flash can optimise the system design and cost. ![]() By using a 1.2V Flash, the SoC can connect directly to the SPI Flash without a level shifter, reducing the BOM cost and PCB space. This results in additional costs and adds to the complexity of the system design. As the SoC process evolves to more advanced technology, the I/O voltage of new generation SoC is becoming lower than 1.8V and will require a level-shifter to connect to a traditional 1.8V/3V SPI Flash. Operating at 1.2V and drawing the same Read mode current of 4mA at 50MHz, the W25Q64NE’s power consumption is just 4.8mW, providing an instant 33% power saving by replacing 1.8V flash.Īpart from power saving, a new system design also offers additional benefits. In active Read mode at an operating frequency of 50MHz, a 1.8V SpiFlash part’s operating current of 4mA results in power consumption of 7.2mW. 【Download】 Optimizing SoC performance in-life with Embedded Analytics
