16 Mbit Multi-Purpose Flash Plus SST39VF1681 / SST39VF1682 A Microchip Technology Company Data Sheet Device Operation Commands are used to initiate the memory operation functions of the device. Commands are written to the device using standard microprocessor write sequences. A command is written by asserting WE# low while keeping CE# low. The address bus is latched on the falling edge of WE# or CE#, whichever occurs last. The data bus is latched on the rising edge of WE# or CE#, whichever occurs first.
16 Mbit Multi-Purpose Flash Plus SST39VF1681 / SST39VF1682 A Microchip Technology Company Data Sheet timing waveforms and Figure 24 for the flowchart. Any commands issued during the Sector- or BlockErase operation are ignored. When WP# is low, any attempt to Sector- (Block-) Erase the protected block will be ignored. During the command sequence, WP# should be statically held high or low.
16 Mbit Multi-Purpose Flash Plus SST39VF1681 / SST39VF1682 A Microchip Technology Company Data Sheet duce a ‘0’. Once the internal Erase operation is completed, DQ7 will produce a ‘1’. The Data# Polling is valid after the rising edge of fourth WE# (or CE#) pulse for Program operation. For Sector-, Block- or Chip-Erase, the Data# Polling is valid after the rising edge of sixth WE# (or CE#) pulse. See Figure 7 for Data# Polling timing diagram and Figure 21 for a flowchart.
16 Mbit Multi-Purpose Flash Plus SST39VF1681 / SST39VF1682 A Microchip Technology Company Data Sheet Hardware Block Protection The SST39VF1682 supports top hardware block protection, which protects the top 64 KByte block of the device. The SST39VF1681 supports bottom hardware block protection, which protects the bottom 64 KByte block of the device. The Boot Block address ranges are described in Table 3. Program and Erase operations are prevented on the 64 KByte when WP# is low.
16 Mbit Multi-Purpose Flash Plus SST39VF1681 / SST39VF1682 A Microchip Technology Company Data Sheet Product Identification The Product Identification mode identifies the devices as the SST39VF1681 and SST39VF1682, and manufacturer as SST. Users may use the software Product Identification operation to identify the part (i.e., using the device ID) when using multiple manufacturers in the same socket.
