STMicroelectronics provides a recommended PCB layout in the application note AN5563, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
The M95640-WBN6 has a thermal pad that must be connected to a thermal ground plane on the PCB to dissipate heat. A thermal interface material (TIM) can be used to improve heat transfer. Additionally, ensure good airflow around the device and avoid blocking the thermal pad with components or soldermask.
The M95640-WBN6 is rated for operation from -40°C to 125°C (junction temperature). However, the device's performance and reliability may degrade at extreme temperatures. It's essential to ensure the device operates within the recommended temperature range for optimal performance and longevity.
The M95640-WBN6 can be programmed using the STMicroelectronics Serial Flash Programmer (SFP) software and a compatible programmer hardware, such as the ST-LINK/V2. The programming interface is SPI, and the device supports various programming modes, including serial and page programming.
The M95640-WBN6 has a minimum data retention period of 20 years at 125°C, and 100 years at 85°C, based on the JEDEC standard JESD47. However, the actual data retention period may vary depending on the operating conditions and storage environment.
