SRAM Keep-Alive Power Behavior
The IRAMSTBY pin provides keep-alive power to RAM when the main power supply is shut down. The
IRAMSTBY pin can be powered directly from a battery using an internal shunt regulator or via a small
battery for standby use. See
.
Figure 1-2. Recommended Connection Diagram for IRAMSTBY
While power is off, the IRAMSTBY supply powers the following:
•
32-Kbyte CALRAM
•
8-Kbyte DPTRAM module
•
2-Kbyte BBC DECRAM module
NOTE
IRAMSTBY must always be supplied with at least 50
µ
A for correct
operation.

MPC561/MPC563 Address Map
The internal memory map is organized as a single 4-Mbyte block. The user can assign this block to one of
eight locations by programming a register in the USIU (IMMR[ISB]). The eight possible locations are the
