The 112 I/O lines, routed through a 144-LQFP package (20x20 mm footprint), provide ample GPIO for sensor arrays, display interfaces, and motor-control feedback.
1.4 MB RAM and 280 MHz — sizing the compute and data budget
The 280 MHz Cortex-M7 core handles DSP-style math and real-time control loops that would stall a 100 MHz MCU. With 1.4 MB of SRAM, this part can buffer multiple camera frames, hold a large audio sample pool, or run a TCP/IP stack with generous socket buffers — all on-chip. The 2 MB Flash supports a full-featured firmware image with a bootloader, application code, and a file system for configuration data. For designs that need more memory, the EBI/EMI interface (listed in the connectivity block) lets you attach external SDRAM or NOR Flash without a glue-logic CPLD.
Connectivity and peripherals — what the 112 I/O actually connects to
The peripheral set covers industrial and consumer interfaces: CANbus for automotive or machinery networks, USB OTG for device-to-host communication, multiple SPI and I²C buses for sensors and converters, SAI for I²S audio, and an LCD parallel interface for TFT displays. The 20-channel 16-bit ADC and three 12-bit DAC handle analog front-end tasks without an external converter. Brown-out detect and POR simplify power sequencing, while the DMA engine moves data without loading the core.
Package and supply — layout decisions for the 144-LQFP
The 144-LQFP (20x20 mm) is a standard QFP with 0.5 mm pitch — easier to route and rework than a BGA of equivalent I/O count. The supply range of 1.62 V to 3.6 V lets it run from a single 3.3 V rail or a 1.8 V low-power domain. Surface-mount assembly follows typical LQFP profiles; no special bake-out is required if the moisture-barrier bag is intact.
