4 Mbit (x16) Multi-Purpose Flash
A Microchip Technology Company
SST39WF400B
Data Sheet
Product Description
The SST39WF400B is a 256K x16 CMOS Multi-Purpose Flash (MPF) manufactured with SST proprie-
tary, high-performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tun-
neling injector attain better reliability and manufacturability compared to alternate approaches. The
SST39WF400B writes (Program or Erase) with a 1.65-1.95V power supply. This device conforms to
JEDEC standard pin assignments for x16 memories.
The SST39WF400B features high-performance Word-Programming which provides a typical Word-
Program time of 28 μsec. It uses Toggle Bit or Data# Polling to detect the completion of the Program or
Erase operation. On-chip hardware and software data protection schemes protect against inadvertent
writes. Designed, manufactured, and tested for a wide spectrum of applications, the SST39WF400B is
offered with a guaranteed typical endurance of 100,000 cycles. Data retention is rated at greater than
100 years.
The SST39WF400B is suited for applications that require convenient and economical updating of pro-
gram, configuration, or data memory. For all system applications, this MPF significantly improves per-
formance and reliability, while lowering power consumption. It inherently uses less energy during Erase
and Program than alternative flash technologies. When programming a flash device, the total energy
consumed is a function of the applied voltage, current, and time of application. For any given voltage
range, SuperFlash technology uses less current to program and has a shorter erase time; therefore,
the total energy consumed during any Erase or Program operation is less than alternative flash tech-
nologies. These devices also improve flexibility while lowering the cost for program, data, and configu-
ration storage applications.
SuperFlash technology provides fixed Erase and Program times independent of the number of Erase/
Program cycles that have occurred. Consequently, 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/Program cycles.
To meet surface mount requirements, the SST39WF400B is offered in 48-ball TFBGA, 48-ball
WFBGA, and a 48-ball XFLGA packages. See Figures 2 and 3 for pin assignments and Table 1 for pin
descriptions.
