说明
SM28VLT32 是一款 32 兆位闪存存储器,此存储器设计用于存储程序代码和/或采集到的数据。 这个器件的宽温度
额定值使得它非常适合于需要在恶劣环境中可靠执行的应用。 SM28VLT32 借助于它的串行外设接口 (SPI) 提供低
引脚数量以实现额外的可靠性以及这些应用中的简便组装。
存储器被分区成扇区以提供每个 16 位的 2M 字寻址。 因此,存储器地址为 21 位宽。
SM28VLT32 支持串行外设接口以在闪存存储器中读取/写入/擦除数据。 此接口与模式 0 (CPOL = 0,CPHA = 0)
和 3 (CPOL = 1,CPHA = 1) 兼容。 将 CS# 置为有效将使器件进入通信模式。 在 CS# 被取消置位时,器件忽略
SPI 引脚上的所有活动。 如图 1中所示,为了在应用中实现较大存储器,可通过独立控制 CS# 引脚由一个单个主
控器件来控制多个 SM28VLT32 器件。 将 HOLD# 引脚置为有效(同时 CS# 也被置位)将使器件忽略其它 SPI 输
入引脚(SCK 和 SI)上的活动。

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

DETAILED DESCRIPTION
SERIAL COMMUNICATION
SM28VLT32 supports mode 0 and mode 3 SPI protocols. In mode 0, the inactive state of SCK is 0 whereas, in
mode 3, the state is 1. The input data on SI is always latched on rising edge of SCK and data on SO is output on
falling edge of SCK in both modes. CS# is brought low to start a new SPI data frame. The SPI data frame
consists of an 8-bit command byte followed by a variable number of bytes of input data as shown in Table 3. The
first 8 bits of SO always output the quick status bits. These bits define error conditions and status of the FLASH
(see Table 4). These bits should be evaluated after each command is executed to determine if the preceding
command completed successfully. This can be implemented as part of the SPI communication protocol with the
host device. For more information see the Application Information section. The output data on SO follows after
the complete data is provided to the device on SI pin. Invalid command bytes are ignored. Also, any additional
SCK clock cycles and additional data on SI beyond the depicted frame size are ignored. CS# going high
delineates the end of current data frame.

ZHCSAT2C –NOVEMBER 2012–REVISED MARCH 2013
APPLICATION INFORMATION
The quick status register is intended to be used as feedback of device and command status. The host should
evaluate the quick status results at each command execution to determine device status. Additionally, two of the
error fields in the quick status are sticky. They will need to be intentionally cleared by the host once detected.
The Command and Invalid Data error flags will not self clear. The command error bit indicates that a command
failed. This can be either an erase or program command. If this was a program attempt, then the data written
may not be valid. The host may decide to re-write this data or pursue some other error recovery path. The Invalid
data bit will get set if an attempt to write a bit to a logical 1 (erased state) in a word that has that bit already
programmed to a 0. This would likely be the first error seen when writing to an array that contains data. To clear
a Command error or Invalid Data error, the host must execute the following SPI command sequence: 1F 00 40
xx. xx is a dummy byte and values are don't care. This SPI command is a special command that is sent to the
internal flash controller to clear errors.
It is important to note that the quick status capture of the internal setting of the Command error and the Invalid
Data flags are delayed by one transaction. Similarly, the Device Busy flag does not get cleared until a second
transaction. For example, in the case of polling after a write. If this write generated an Invalid Data error, the
sequence would be as follows.
SPI WRITE
SPI READ
DESCRIPTION
Write to address 0 with erased value This will cause Invalid Data error if word has
been programmed.
0x17_0000_FFFF
00_xxxx_xxxx
0xFF
0xFF
08
04
Execute quick status. This result is Device Busy.
Execute quick status with Invalid Data error.
Similarly, if a write or program fails, then the Command error status will show on the second transaction after the
failed command. To effectively deal with this in a protocol, the best method is to poll the quick status twice to
validate no error occurred. For applications that this method is too costly for SPI bandwidth, the error can be
trapped on execution of the following commands with the knowledge that the error belonged to the command 2
transactions earlier.
The SPI Frame error and the Read error are errors that return correct status on the next quick status. These two
errors are not sticky and only apply to the prior transaction.
Provisions for Operating With fCLK Frequencies Less than 12 MHz
The SM28VLT32 uses a state machine and registers to implement the correct algorithms for programing, erasure
and validation. The register values define counters and loops that determine appropriate setup and hold times,
maximum attempts, pulse widths, and other critical parameters. The default values of these registers are defined
for fCLK operation in the 10 MHz to 12 MHz range. Operating below 10 MHhz requires changing key registers to
properly implement the algorithm. See Table 6 for register settings for specific fCLK ranges. Note, the 10 MHz to
12 MHz values are provided, but are not required to be written as they are the reset defaults. Additionally, the
SPI SCLK frequency must be 5/6ths of fCLK or slower for reliable operation.
The values below represent the address and value that should be written using the 1D command. Note that first
line is a write to F004. This must be first, as it unlocks the test control register and allows modification of the
memory mapped registers. Without this write, the contents of the register would not change. It is recommended
to follow the register writes with a read to verify that change was properly implemented. The last line is a write
back to the test control register to relock it preventing accidental modification of the registers.

(1) fCLK cannot be operated lower than 2 MHz.
Initialization of the register values must be repeated on power cycle or RST assertion.
Power Supply Sequencing
The ideal power supply sequence is VCORE coming up before VIO (VCORE > 1.65 V before VIO greater than
0.8 V).
For powerdown, the reverse is also true. VIO should be below 0.8 V before VCORE is < 1.65 V.
Alternatively, VIO can come up first or simultaneously with VCORE if RST is asserted low until both supplies are
within recommended operating range. Similarly if device is active, it is necessary to assert RST prior to powering
down to minimize chance of corrupting the flash array.
Power Saving Features
The device has power saving capabilities that allow it to be put into either standby or sleep states for the banks
and flash pump when periods of inactivity are detected. When an access is initiated during sleep or standby, the
pump and banks will transition to the active state automatically. Use of these features does not have protocol
impact on programming (other than additional time required to wake up), as the device will report Write Busy.
However, during read operations, the device will report Read error on next quick status read. This is due to the
fact that a read transaction is immediate, while a write is queued. The value read from an address that is in
standby or sleep will be 00 00. Reference Application Note: "Using the SM28VLT32-HT With Power Saving
Features" (SLVA550).
