PRODUCT FAMILY OVERVIEW This datasheet contains the specifications for the two branches of products in the SmartVoltage 8-Mbit boot block flash memory family: the -BE/CE suffix products feature a low VCC operating range of 2.73.6V; the -BV/CV suffix products offer 3.03.6V operation. Both BE/CE and BV/CV products also operate at 5V for high-speed access times. Throughout this datasheet, the 28F800 refers to all x8/x16 8-Mbit products, while 28F008B refers to all x8 8-Mbit boot block products (but not to the 28F008SA FlashFileTM Memory). Also, the term "2.7V" generally means the full voltage range 2.73.6V. Section 1 provides an overview of the flash memory family including applications, pinouts and pin descriptions. Sections 2 and 3 describe the memory organization and operation for these products. Finally, Sections 4, 5 and 6 contain the family's operating specifications. 1.1 New Features in the SmartVoltage Products The new 8-Mbit SmartVoltage boot block flash memory family provides a convenient density upgrade path from the 2-Mbit and 4-Mbit boot block products. The 8-Mbit boot block functions similarly to lower density boot block products in both command sets and operation, providing similar pinouts to ease density upgrades.

To upgrade from lower density -BX/BLsuffix 12V program products, please note the following differences and guidelines:
·
WP# pin has replaced DU (Don't Use) pin #12 in the 40-lead TSOP package. In the 44-lead PSOP, DU pin #2 is replaced with A18 (see Figure 1 and Section 3.4 for details). Connect the WP# pin to control signal or to V C or C GND (in this case, a logic-level signal can be placed on DU pin #12 for 40lead TSOP). See Tables 2 and 9 to see how the WP# pin works. 5V program/erase operation has been added. If switching VPP for write protection, switch to GND (not 5V) for complete write protection. To take advantage of 5V write-capability, allow for connecting 5V to VPP and disconnecting 12V from VPP line.
·
Enhanced circuits optimize low V C C performance, allowing operation down to VCC = 2.7V (using the BE/CE products). To upgrade from lower density SmartVoltage boot block products, the similar pinouts in the 40-lead and 48-lead TSOP packages provide easy upgrades by adding extra address lines (see Figures1 and 3). In the 44-lead TSOP, the WP# pin on the 2-Mbit and 4-Mbit BV parts becomes A18, removing the capability to unlock the boot block with a logic-level signal in this package only. The boot block can still be unlocked with 12V on RP# (see Figure 2 and Section 3.4 for details).

1.2 Main Features Intel's SmartVoltage technology is the most flexible voltage solution in the flash industry, providing two discrete voltage supply pins: VCC for read operation, and VPP for program and erase operation. Discrete supply pins allow system designers to use the optimal voltage levels for their design. All products (28F800BV/CV, 28F008BV, 28F800CE and 28F008BE) provide program/erase capability at 5V or 12V. The 28F800BV/CV and 28F008BV allows reads with VCC at 3.3 ± 0.3V or 5V, while the 28F800CE and 28F008BE allows reads with VCC at 2.73.6V or 5V. Since many designs read from the flash memory a large percentage of the time, 2.7V VCC operation can provide great power savings. If read performance is an issue, however, 5V V C C provides faster read access times. For program and erase operations, 5V V P P operation eliminates the need for in system voltage converters, while 12V VPP operation provides faster program and erase for situations where 12V is available, such as manufacturing or designs where 12V is insystem. For design simplicity, however, just hook up VCC and VPP to the same 5V ± 10% source. The 28F800/28F008B boot block flash memory family is a high-performance, 8-Mbit (8,388,608 bit) flash memory family organized as either 512 Kwords of 16 bits each (28F800 only) or 1024 Kbytes of 8 bits each (28F800 and 28F008B). Separately erasable blocks, including a hardware-lockable boot block (16,384 bytes), two parameter blocks (8,192 bytes each) and main blocks (one block of 98,304 bytes and seven blocks of 131,072 bytes) define the boot block flash family

architecture. See Figures 4 and 5 for memory maps. Each block can be independently erased and programmed 100,000 times at commercial temperature or 10,000 times at extended temperature. The boot block is located at either the top (denoted by -T suffix) or the bottom (-B suffix) of the address map in order to accommodate different microprocessor protocols for boot code location. The hardware-lockable boot block provides complete code security for the kernel code required for system initialization. Locking and unlocking of the boot block is controlled by WP# and/or RP# (see Section 3.4 for details).
