Figure 2-1 DSP56824ADM Functional Block Diagram
2.3.1
Fast Static RAM (FSRAM)
The DSP56824ADM uses two banks of 64K × 16-bit Fast Static RAM (Motorola
MCM6323A, labelled U6 and U7) for memory expansion. U6 provides program
memory, and U7 provides data memory. U6 is addressed for use in the DSP's program
memory space. The FSRAM U7 is addressed for use in the DSP's data memory space.
The on-board jumpers JG3 and JG13 allow configuration of the FSRAM and NVSRAM in
the program memory space. The on-board jumper JG4 allows configuration of the
FSRAM in the data memory space. Refer to Table 2-4 on page 2-10 and Table 2-5
on page 2-12 for setting these jumpers.
