STM32L496xx

Functional overview

without having any impact on the timing of “injected” conversions

–

“injected” conversions for precise timing and with high conversion priority

3.25

Random number generator (RNG)

All devices embed an RNG that delivers 32-bit random numbers generated by an integrated

analog circuit.

3.26

Digital camera interface (DCMI)

The devices embed a camera interface that can connect with camera modules and CMOS

sensors through an 8-bit to 14-bit parallel interface, to receive video data. The camera

interface can sustain a data transfer rate up to 54 Mbyte/s at 54 MHz. It features:

•

Programmable polarity for the input pixel clock and synchronization signals

•

Parallel data communication can be 8-, 10-, 12- or 14-bit

•

Supports 8-bit progressive video monochrome or raw bayer format, YCbCr 4:2:2

progressive video, RGB 565 progressive video or compressed data (like JPEG)

•

Supports continuous mode or snapshot (a single frame) mode

•

Capability to automatically crop the image

Timers and watchdogs

The STM32L496xx includes two advanced control timers, up to nine general-purpose

timers, two basic timers, two low-power timers, two watchdog timers and a SysTick timer.

The table below compares the features of the advanced control, general purpose and basic

timers.
