Housed in a 143-ball WLCSP measuring 4.52 x 5.55 mm, this is a fine-pitch wafer-level chip-scale package intended for space-constrained designs where board real estate is at a premium. Any remaining stock in the independent distribution channel is finite and being consumed. For sustainment programs already using this MCU, the procurement path is the surplus and broker market. ## 114 I/Os and the WLCSP footprint — board-level considerations With 114 general-purpose I/Os brought out on a 143-ball WLCSP, every ball carries a signal — there are no NC balls to simplify routing. The 0.4 mm pitch (typical for this package class) requires a high-density PCB process with microvias and a controlled impedance stackup if the Ethernet or USB differential pairs are used. Brown-out detect and POR are integrated, so no external supervisor is needed for basic reset functionality. The internal oscillator means the part can run without an external crystal for non-timing-critical applications, though the Ethernet and USB PHY interfaces will require an external clock source.","metaTitle":"STM32F429ZIY6JTR STM32F4 MCU, 180MHz, 2MB Flash, 143-WLCSP","metaDescription":"STMicroelectronics STM32F429ZIY6JTR ARM Cortex-M4 MCU, 180MHz, 2MB Flash, 256KB RAM, 143-WLCSP.

The STM32F429 base family includes other package options (LQFP176, LQFP208, BGA176) that share the same core and memory but differ in footprint. For a WLCSP replacement, the STM32F439 line offers similar peripherals with additional cryptographic acceleration, but pin compatibility must be verified against the specific ball map. No drop-in replacement is guaranteed without a PCB respin."},{"question":"Is STM32F429ZIY6JTR compatible with STM32F429ZIY6?","answer":"The STM32F429ZIY6JTR and STM32F429ZIY6 share the same base product number STM32F429 and the same 2 MB Flash / 256 KB RAM memory configuration. The difference is the package suffix: Y6JTR indicates the 143-WLCSP variant on Tape & Reel, while Y6 typically refers to a different package option (often a BGA or LQFP). They are not pin-compatible — the ball/pin assignments differ. Do not assume a drop-in replacement without comparing the package drawings."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F429ZIY6JTR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F429ZIY6JTR when reusing this data.
