120 MHz Cortex-M4 with 1 MB Flash — memory headroom for complex firmware
The 32-bit single-core processor includes a single-precision FPU for math-heavy loops in motor control or sensor fusion. The 1 MB Flash is organized as 1M x 8 bits, and the 320 KB SRAM as 320K x 8 bits. This memory configuration supports dual-bank OTA updates or large display buffers when driving the integrated LCD controller.
Connectivity and peripheral set — USB OTG, CAN, and multiple serial buses
The EBI/EMI bus allows glueless connection to external parallel memory or FPGAs. For analog sensing, there are 16 channels of 12-bit ADC and two 12-bit DAC channels. The USB OTG peripheral supports host and device modes, making this part a candidate for USB-based data loggers or industrial HMI panels that connect to a keyboard or thumb drive.
Package and footprint — 48-LQFP (7x7 mm)
Housed in a 48-LQFP package with a 7x7 mm body, the STM32L4Q5CGT6 is a surface-mount device. The 48-pin LQFP footprint is common across the STM32L4 value-line, easing layout reuse if migrating between density options.
