Product details

The STM32F778AIY6TR is a 32-bit ARM Cortex-M7 MCU running at 216 MHz with 2 MB of Flash and 512K x 8 of RAM. The 129 I/O and peripheral set include CAN, USB OTG, SPI, I²C, SAI, QSPI, and an LCD controller.

What the 2 MB Flash and 512K RAM mean for firmware

2 MB of Flash is enough for a full-featured RTOS, a TCP/IP stack, a graphics library, and application code — think a 7-inch HMI with 800x480 display or a multi-axis servo controller with EtherCAT slave firmware. The 512K x 8 RAM (512 KB) supports double-buffered frame buffers and moderate data logging. The internal oscillator and brown-out detect reduce external BOM count, but for a precision timing application the internal RC will drift; an external crystal is still the right call.

Frequently asked questions

Where can I buy STM32F778AIY6TR and get a price?

We source and quote this part to order against an RFQ through our independent distribution network. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm quote.

What is the closest pin-compatible alternative to STM32F778AIY6TR?

No official pin-compatible successor is listed. The WLCSP-180 footprint is unique to this density tier. A board respin to a BGA-176 package (e.g., STM32F769) would be required for a functional equivalent.

What is STM32F778AIY6TR's listed speed?

The core runs at 216 MHz on an ARM Cortex-M7.

What series is STM32F778AIY6TR from?

It belongs to the STM32F7 series.
