provides decoded chip enables for SRAM. This leaves the 32 I/O port pins free for application use. The
DS5000FP uses ordinary SRAM and battery backs the memory contents with a user’s external lithium
cell. Data is maintained for over 10 years with a very small lithium cell. A DS5000FP also provides
crashproof operation in portable systems or systems with unreliable power. These features include the
ability to save the operating state, Power-fail Reset, Power-fail Interrupt, and Watchdog Timer.
A user loads programs into the DS5000FP via its on-chip Serial Bootstrap Loader. This function
supervises the loading of code into NV RAM, validates it, then becomes transparent to the user. Software
can be stored in an 8-kbyte or 32-kbyte CMOS SRAM. Using its internal Partitioning, the DS5000FP will
divide this common RAM into user programmable code and data segments.
This Partition can be
selected at program loading time, but can be modified anytime later. It will decode memory access to the
SRAM, communicate via its Byte-wide bus and write-protect the memory portion designated as ROM.
Combining program and data storage in one device saves board space and cost. The DS5000FP can also
access a second 32 kbytes of NV RAM but this area is restricted to data memory. For a user that wants a
pre-constructed module using the DS5000FP, RAM, lithium cell, and optional real time clock; the
DS2250(T) and DS5000(T) are available and described in separate data sheets. More details are also
contained in the User’s Guide section of the Secure Microcontroller Data Book.
