MEMORY MAP DESCRIPTIONS
DEVICE IDENTIFIER
The device identifier (ID) is based on the manufacturer ID found in IEEE standard 1149.1 on Boundary Scan,
and the ID assigned by the Solid State Products Engineering Council (JEDEC). The serial format for this ID is
shown below:
The device identifier is not currently provided as a boundary scan message. However, the manufacturer ID and
part number are implemented with read-only capability for microprocessor read access. The manufacturer ID
given for all TranSwitch chips is 107 (06B hex.). The part number of the L4M device is 03456 (0D80 hex.) in
binary. In addition, the read-only segment is expanded to include a 4-bit mask level field and a 4-bit future
growth field as shown below:
