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.
2.3.2 Non-Volatile Static RAM (NVSRAM) The DSP56824ADM provides two 32K × 8-bit NVSRAM memory devices, installed as U9 and U10, to give a total of 32K × 16-bit NVSRAM memory. External Program RAM must be configured for operation in the lower program memory address space ($0000–$7FFF).
LED Indicators Two on-board Light-Emitting Diodes (LEDs) are provided. LED1 is a power indicator that shows when power is applied to the DSP56824ADM board. LED2 is a debugging indicator. See PB14 Indicator LED Configuration on page 2-15 for more information on LED2.
10 MHz user oscillator clock (default) 1–2 External clock CLOCK_IN on J2 pin 1 3–4 Note: The DSP56824ADM is factory configured to use the on-board 10 MHz clock oscillator (U12). 2.6.2 User Clock Oscillator V Setting Jumper group JG9 is used to select the power source (3.3 V or 5.0 V) for the Clock Oscillator (U12).
Normal Expanded P:$E000 (default) No jumpers Development P:$0000 Note: The DSP56824ADM is factory configured to exit from reset in Mode 2. 2.6.4 Program Memory Configuration Jumper group JG3 selects the external program static RAM memory configuration. For fastest operation with the installed 10 ns FSRAM, jumper pins JG3 1–2 and 3–4, and configure the Bus Control Register (BCR) for zero wait states.
P:$0000–$7FFF, zero wait states P:$8000–$FFFF Shadow of P:$0000–$7FFF 1–2 NVSRAM: P:$8000–$FFFF Note: The DSP56824ADM is factory configured for in the range program memory P:$0000–$7FFF (FSRAM) and P:$8000–$FFFF (NVSRAM). To load a program into the SIMTEK non-volatile portion of the NVSRAM, perform the following steps.
