PRODUCTION DATA.
MSP432P4x1xT devices support up to 256KB of SRAM, with the rest of the 1-MB SRAM region reserved. The SRAM is aliased in both Code and SRAM zones. This enables fast single-cycle execution of code from the SRAM, as the Cortex-M4 processor pipelines instruction fetches to memory zones other than the Code space. As with the flash memory, the SRAM can be powered down or placed in a low-leakage retention state in low-power modes of operation.
Figure 6-6 shows the memory map of SRAM on MSP432P4x1xT devices.
