Description

11/118

Embedded Flash memory

Up to 512 Kbytes of embedded Flash is available for storing programs and data.

CRC (cyclic redundancy check) calculation unit

The CRC (cyclic redundancy check) calculation unit is used to get a CRC code from a 32-bit

data word and a fixed generator polynomial.

Among other applications, CRC-based techniques are used to verify data transmission or

storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of

verifying the Flash memory integrity. The CRC calculation unit helps compute a signature of

the software during runtime, to be compared with a reference signature generated at link-

time and stored at a given memory location.

Embedded SRAM

Up to 64 Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait

states.

FSMC (flexible static memory controller)

The FSMC is embedded in the STM32F103xC, STM32F103xD and STM32F103xE

performance line family. It has four Chip Select outputs supporting the following modes:

RAM, PSRAM, NOR and NAND.

Functionality overview:

●

The three FSMC interrupt lines are ORed in order to be connected to the NVIC

●

Write FIFO

●

Code execution from external memory except for

●

The targeted frequency is SYSCLK/2, so external access is at 36 MHz when the

system is at 72 MHz and external access is at 24 MHz when the system is at 48 MHz

LCD parallel interface

The FSMC 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.
