8 / 70 page 3 Volt Intel® Advanced+ Boot Block Flash Memory Stacked-CSP Family 8 Datasheet program and erase operations, including verification, thereby unburdening the microprocessor or microcontroller. The flash’s status register indicates the status of the WSM by signifying block erase or word program completion and status. Flash program and erase automation allows program and erase operations to be executed using an industry-standard two-write command sequence to the CUI. Program operations are performed in word increments. Erase operations erase all locations within a block simultaneously. Both program and erase operations can be suspended by the system software in order to read from any other flash block. In addition, data can be programmed to another flash block during an erase suspend. The C3 Stacked-CSP memory device offers two low-power savings features: Automatic Power Savings (APS) for flash memory and standby mode for flash and SRAM. The device automatically enters APS mode following the completion of a read cycle from the flash memory. Standby mode is initiated when the system deselects the device by driving F-CE# and S-CS1# or S-CS2 inactive. Power savings features significantly reduce power consumption. The flash memory can be reset by lowering F-RP# to GND. This provides CPU-memory reset synchronization and additional protection against bus noise that may occur during system reset and power-up/-down sequences. 1.3 Package Ballout 72- NOTES: 1. Flash upgrade balls are shown up to A21 (64-Mbit flash) and A22 (128-Mbit flash). In all flash and SRAM combinations, 66 balls are populated on lower density devices. (Upper address balls are not populated). Ball location A10 is “NC” on 16/2 devices only.
