6.7 RAM Controller (RAMCTL)

MSP430x2xx MCUs do not have a RAM Controller. The RAM Controller allows reduction of the leakage current during LPM3 and LPM4. The RAM is partitioned in one to four sectors, depending on the device. See the device-specific data sheet for sector allocation and size. Each sector can be individually powered down in LPM3 and LMP4 to save leakage. Note that data is lost when sectors are powered down in LPM3 and LPM4.

The FR5962/4 and FR5992/4 MCUs have 8KB of SRAM. The SRAM is made up of three sectors. Sector 0 = 2KB, Sector 1 = 2KB, and Sector 2 = 4KB. The 4KB of Sector 2 is shared with the Low-Energy Accelerator (LEA) peripheral when the LEA module is activated. When the LEA module is not activated, Sector 2 SRAM can be used normally. See the device-specific data sheets for more information.
