Chapter 31
Static RAM (SRAM)
31.1
Introduction
This device has as much as 80 KB of general-purpose static RAM (SRAM).
The SRAM provides the following features:
•
SRAM can be read/written from any bus master
•
Byte, halfword, and word addressable
•
ECC (error correction code) protected with single-bit correction and double-bit detection
31.2
Low power configuration
In order to reduce leakage a portion of the SRAM can be switched off/unpowered during standby mode.
31.3
Register memory map
The L2SRAM occupies 80 KB of memory starting at the base address as shown in
.
The internal SRAM has no registers. Registers for the SRAM ECC are located in the ECSM [see
Chapter 34, Error Correction Status Module (ECSM)

The entire SRAM is powered and operational.
STANDBY
Either 8 KB or 32 KB of the SRAM remains powered. This option is software-selectable.
