LH75400/01/10/11
Static Random Access Memory Controller
of Static Random Access Memory (SRAM) organized
into two 16KB blocks:
• 16KB of TCM 0 Wait State SRAM is available to the
• 16KB of internal SRAM is available as an AHB slave
and internal SRAMs are 16KB each in size. Any access
beyond the first 16KB is mapped to the lower 16KB, but
does not cause a data or prefetch abort.
Static Memory Controller (SMC)
AHB slave peripheral that provides the interface
between the LH75400/01/10/11 microcontrollers and
external memory devices.
SMC FEATURES
