PRODUCT DESCRIPTION
The SST34HF1681 ComboMemory devices integrate a
1M x16 CMOS flash memory bank with a 512K x16 CMOS
SRAM memory bank in a Multi-Chip Package (MCP).
These devices are fabricated using SST’s proprietary, high-
performance CMOS SuperFlash technology incorporating
the split-gate cell design and thick oxide tunneling injector
to attain better reliability and manufacturability compared
with alternate approaches. The SST34HF1681 devices are
ideal for applications such as cellular phones, GPSs, PDAs
and other portable electronic devices in a low power and
small form factor system.
The SST34HF1681 features dual flash memory bank
architecture allowing for concurrent operations between the
two flash memory banks and the SRAM. The devices can
read data from either bank while an Erase or Program
operation is in progress in the opposite bank. The two flash
memory banks are partitioned into 4 Mbit and 12 Mbit with
top or bottom sector protection options for storing boot
code, program code, configuration/parameter data and
user data.
The SuperFlash technology provides fixed Erase and Pro-
gram times, independent of the number of Erase/Program
cycles that have occurred. Therefore, the system software
or hardware does not have to be modified or de-rated as is
necessary with alternative flash technologies, whose Erase
and Program times increase with accumulated Erase/Pro-
gram cycles. The SST34HF1681 devices offer a guaran-
teed endurance of 10,000 cycles. Data retention is rated at
greater than 100 years. With high performance Word-Pro-
gram, the flash memory banks provide a typical Word-Pro-
gram time of 14 μsec. The entire flash memory bank can
be erased and programmed word-by-word in typically 8
seconds for the SST34HF1681, when using interface fea-
tures such as Toggle Bit or Data# Polling to indicate the
completion of Program operation. To protect against inad-
vertent flash write, the SST34HF1681 devices contain on-
chip hardware and software data protection schemes.
The flash and SRAM operate as two independent memory
banks with respective bank enable signals. The memory
bank selection is done by two bank enable signals. The
