USER'S GUIDE

The DS5001FP has several memory options. It can be connected to between one 8K byte SRAM and four 32K byte SRAMs. It will also support one 128K byte SRAM. In most cases the DS5001FP is used for its greater memory access so it will not be used with 8K RAMs. In the Partitionable mode (see Section 4), the DS5001FP can be connected to one or two SRAMs. Figure 5±3 illustrates the connection of two 32K x 8 SRAMs. Each RAM has its own chip enable, with a com- mon WE generated by the DS5001FP R/W signal. When using the DS5001FP with only one RAM, the se- cond chip enable will simply remain unconnected. This solution provides a total of 64K bytes of memory which the user can partitions into program and data segments. The Partition setting has no impact on the interconnect. Using the Partition, the microcontroller determines which memory blocks are program and write protects the ap- propriate addresses.

In the non±partitionable case, the DS5001FP can be connected to three or four 32K x 8 SRAMs. The four RAM case is shown in Figure 5±4. Each RAM has its own chip enable. To use three RAMs, simply omit the unused chip enable (CE2 or 4) as described in Section

4.In other ways, this hardware configuration is similar to the Partitionable mode discussed above. While this provides the full 128K bytes of memory, it requires more space and cost than the version shown in Figure 5±5. This uses the 128K byte SRAM. All program and data memory is contained within the single chip. The DS5001 manages the addressing and decoding. Note the MSEL signal is connected to ground to initiate this mode. The PM bit and Range must still be configured by the user during program loading.
