On-chip data converters include a 12-bit and a 16-bit ADC plus a 12-bit DAC.
There is no official STMicroelectronics replacement listed for this order code; the STM32F3 family has moved to newer process nodes, so any substitution requires a design review of pin compatibility and peripheral set.
48-LQFP footprint and supply rails
The 48-LQFP (7x7 mm) package with a 0.5 mm pitch is a common footprint shared across the STM32F3 value-line density options. The 36 I/Os are enough for a sensor hub or a CAN node with a local display, but the package does not expose all peripherals simultaneously — check the pin-mux table in the datasheet for your specific peripheral set.
