Frequently asked questions
Does the STM32F429ZIT6G need an external Ethernet PHY?
Yes — the integrated Ethernet MAC requires an external 10/100BASE-TX physical layer transceiver. The MAC supports both MII and RMII interfaces; an RMII PHY such as the LAN8720 class is the standard pairing. The MAC does not include the PHY inside the package.
What is the RAM size on the STM32F429ZIT6G and is there a higher-RAM alternative in the same package?
The STM32F429ZIT6G carries 256KB of SRAM. The STM32F4 family includes variants with 256KB and higher RAM in the 144-LQFP footprint at the same 180MHz speed grade. CubeMX should be used to identify the compatible part with the longest supply window — a pin-compatible firmware-compatible variant with 320KB or 384KB SRAM is available in the same package.
What is the dry-pack shelf-life for this Tray-pack part?
MSL rating and bake expiration dates for Tray-pack quantities are product-specific and are confirmed at the point of order through your supplier's incoming test documentation. Submit an RFQ to obtain the MSL floor life, bake date, and ATE open/short/IDD test report for the specific date code on offer.
