8 Mbit (x16) Multi-Purpose Flash Plus
A Microchip Technology Company SST39VF801C / SST39VF802C / SST39LF801C / SST39LF802C
Data Sheet
The SST39VF801C / SST39VF802C / SST39LF801C / SST39LF802C are 512K
x16 CMOS Multi-Purpose Flash Plus (MPF+) manufactured with SST proprietary,
high performance CMOS SuperFlash® technology. The split-gate cell design and
thick-oxide tunneling injector attain better reliability and manufacturability com-
pared with alternate approaches. The SST39VF801C / SST39VF802C /
SST39LF801C / SST39LF802C write (Program or Erase) with a 2.7-3.6V power
supply. These devices conforms to JEDEC standard pinouts for x16 memories.

Functions
AMS1-A0
DQ15-DQ0
Address Inputs To provide memory addresses.
During Sector-Erase AMS-A11 address lines will select the sector.
During Block-Erase AMS-A15 address lines will select the block.
Data Input/output To output data during Read cycles and receive input data during Write cycles.
Data is internally latched during a Write cycle.
The outputs are in tri-state when OE# or CE# is high.
WP#
Write Protect
To protect the top/bottom boot block from Erase/Program operation when
grounded.
RST#
Reset
To reset and return the device to Read mode.
CE#
Chip Enable
To activate the device when CE# is low.
OE#
Output Enable To gate the data output buffers.
WE#
Write Enable
To control the Write operations.
VDD Power Supply To provide power supply voltage: 2.7-3.6V
VSS Ground
NC No Connection Unconnected pins.
RY/BY# Ready/Busy#
To output the status of a Program or Erase operation
RY/BY# is a open drain output, so a 10K - 100K pull-up resistor is required
to allow RY/BY# to transition high indicating the device is ready to read.

Data Sheet
the specific software command codes. During SDP command sequence, invalid commands will abort
the device to read mode within TRC. The contents of DQ15-DQ8 can be VIL or VIH, but no other value,
during any SDP command sequence.
Common Flash Memory Interface (CFI)
The SST39VF801C/802C and SST39LF801C/802C also contain the CFI information to describe the
characteristics of the device. In order to enter the CFI Query mode, the system writes a three-byte
sequence, same as product ID entry command with 98H (CFI Query command) to address 555H in
the last byte sequence. Additionally, the system can use the one-byte sequence with 55H on the
Address and 89H on the Data Bus to enter the CFI Query mode. Once the device enters the CFI
Query mode, the system can read CFI data at the addresses given in Tables 8 through 10. The system
must write the CFI Exit command to return to Read mode from the CFI Query mode.
Product Identification
The Product Identification mode identifies the devices as the SST39VF801C / SST39VF802C /
SST39LF801C / SST39LF802C, and manufacturer as SST. This mode may be accessed software
operations. 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. For details, see Table 7 for soft-
ware operation, Figure 14 for the Software ID Entry and Read timing diagram and Figure 24 for the
Software ID Entry command sequence flowchart.

Product Identification Mode Exit/CFI Mode Exit
In order to return to the standard Read mode, the Software Product Identification mode must be exited.
Exit is accomplished by issuing the Software ID Exit command sequence, which returns the device to
the Read mode. This command may also be used to reset the device to the Read mode after any inad-
vertent transient condition that apparently causes the device to behave abnormally, e.g., not read cor-
rectly. Please note that the Software ID Exit/CFI Exit command is ignored during an internal Program
or Erase operation. See Table 7 for software command codes, Figure 16 for timing waveform, and Fig-
ure 25 for flowcharts.
