STM32H562xx and STM32H563xx

Functional overview

•

256 x 16-bit local memory

•

Up to three areas can be defined in memory for data buffers (two input, one output),

defined by programmable base address pointers and associated size registers

•

Input and output buffers can be circular

•

Filter functions: FIR, IIR (direct form 1)

•

Vector functions: dot product, convolution, correlation

•

AHB slave interface

•

DMA read and write data channels

Flexible memory controller (FMC)

The FMC includes three memory controllers:

•

NOR/PSRAM memory controller

•

NAND memory controller

•

SDRAM memory controller

The main features of the FMC controller are the following:

•

Interface with static-memory mapped devices including:

–

Static random access memory (SRAM)

–

NOR flash memory/OneNAND flash memory

–

PSRAM (four memory banks)

–

NAND flash memory with ECC hardware to check up to 8 Kbytes of data

–

Ferroelectric RAM (FRAM, FeRAM)

•

Interface with synchronous DRAM (SDRAM/Mobile LPSDR SDRAM)

•

8-,16- bit data bus width

•

Independent chip select control for each memory bank

•

Independent configuration for each memory bank

•

Write FIFO

3.21.1

LCD parallel interface

The FMC can be configured to interface seamlessly with most graphic LCD controllers. It

supports the Intel® 8080 and Motorola® 6800 modes, and is flexible enough to adapt to

specific LCD interfaces.

This LCD parallel interface capability makes it easy to build cost effective graphic

applications using LCD modules with embedded controllers or high-performance solutions

using external controllers with dedicated acceleration.

3.21.2

FMC TrustZone security

When the TrustZone security is enabled, the whole FMC banks are secure after reset.

Nonsecure area can be configured using the TZSC MPCWMx controller.

•

The FMC NOR/PSRAM bank:

–

Up to two nonsecure area can be configured thought the TZSC MPCWM2

controller with a 64-Kbyte granularity

•

The FMC NAND bank:
