SST39VF3201C / SST39VF3202C
Preliminary Specifications
Ready/Busy# (RY/BY#)
The devices include a Ready/Busy# (RY/BY#) output signal. RY/BY# is an open drain output pin that
indicates whether an Erase or Program operation is in progress. Since RY/BY# is an open drain out-
put, it allows several devices to be tied in parallel to V DD via an external pull-up resistor. After the rising
edge of the final WE# pulse in the command sequence, the RY/BY# status is valid.
When RY/BY# is actively pulled low, it indicates that an Erase or Program operation is in progress.
When RY/BY# is high (Ready), the devices may be read or left in standby mode.
Data Protection
The SST39VF3201C/3202C provide both hardware and software features to protect nonvolatile data
from inadvertent writes.
Hardware Data Protection
Noise/Glitch Protection: A WE# or CE# pulse of less than 5 ns will not initiate a write cycle.
V DD Power Up/Down Detection: The Write operation is inhibited when V DD is less than 1.5V.
Write Inhibit Mode: Forcing OE# low, CE# high, or WE# high will inhibit the Write operation. This pre-
vents inadvertent writes during power-up or power-down.
Hardware Block Protection
The SST39VF3202C support top hardware block protection, which protects the top two 4-KWord
blocks of the device. The SST39VF3201C support bottom hardware block protection, which protects
the bottom two 4-KWord blocks of the device. The Boot Block address ranges are described in Table 4.
Program and Erase operations are prevented on the two 4-KWord blocks when WP# is low. If WP# is
left floating, it is internally held high via a pull-up resistor, and the Boot Block is unprotected, enabling
Program and Erase operations on that block.

Hardware Reset (RST#)
The RST# pin provides a hardware method of resetting the device to read array data. When the RST#
pin is held low for at least T RP, any in-progress operation will terminate and return to Read mode. When
no internal Program/Erase operation is in progress, a minimum period of T RHR is required after RST#
is driven high before a valid Read can take place. See Figure 17.
The Erase or Program operation that has been interrupted needs to be re-initiated after the device
resumes normal operation mode to ensure data integrity.
