• Manufacturer Part Number: lrs1383
• Description: Stacked Chip 32m Flash And 8m Sram
• Manufacturer: Sharp Microelectronics of the Americas

NOTE:
1. The burst wrap bit (RCR.3) determines whether 4- or 8-word burst-accesses wrap within the burst-length boundary or
whether they cross word-length boundaries to perform linear accesses.
In the no-wrap mode (RCR.3=1), the device operates similar to continuous linear burst mode but consumes less power
during 4- and 8-word bursts.
