Flexible static memory controller (FSMC)

RM0008

19.5

NOR Flash/PSRAM controller

The FSMC generates the appropriate signal timings to drive the following types of

memories:

●

Asynchronous SRAM and ROM

–

–

–

8-bit

16-bit

32-bit

●

PSRAM (Cellular RAM)

–

–

Asynchronous mode

Burst mode

●

NOR Flash

–

–

Asynchronous mode or burst mode

Multiplexed or nonmultiplexed

The FSMC outputs a unique chip select signal NE[4:1] per bank. All the other signals

(addresses, data and control) are shared.

For synchronous accesses, the FSMC issues the clock (CLK) to the selected external

device. This clock is a submultiple of the HCLK clock. The size of each bank is fixed and

equal to 64 Mbytes.

Each bank is configured by means of dedicated registers (see Section 19.6.7 ).

The programmable memory parameters include access timings (see Table 88 ) and support

for wrap and wait management (for PSRAM and NOR Flash accessed in burst mode).
