SST25VF016B
16 Mbit SPI Serial Flash
Features
Product Description
• Single Voltage Read and Write Operations
- 2.7-3.6V
The 25 series Serial Flash family features a four-wire,
SPI-compatible interface that allows for a low pin-count
package which occupies less board space and ulti-
mately lowers total system costs. The SST25VF016B
devices are enhanced with improved operating fre-
quency and even lower power consumption than the
original SST25VFxxxA devices. SST25VF016B SPI
serial flash memories are manufactured with propri-
etary, high-performance CMOS SuperFlash technol-
ogy. The split-gate cell design and thick-oxide tunneling
injector attain better reliability and manufacturability
compared with alternate approaches.
• Serial Interface Architecture
- SPI Compatible: Mode 0 and Mode 3
• High Speed Clock Frequency
- Up to 50 MHz
• Superior Reliability
- Endurance: 100,000 Cycles (typical)
- Greater than 100 years Data Retention
• Low Power Consumption:
- Active Read Current: 10 mA (typical)
- Standby Current: 5 µA (typical)
SST25VF016B devices significantly improve perfor-
mance and reliability, while lowering power consump-
tion. The devices write (Program or Erase) with a single
power supply of 2.7-3.6V for SST25VF016B. The total
energy consumed is a function of the applied voltage,
current, and time of application. Since for any given
voltage range, the SuperFlash technology uses less
current to program and has a shorter erase time, the
total energy consumed during any Erase or Program
operation is less than alternative flash memory technol-
ogies.
• Flexible Erase Capability
- Uniform 4 KByte sectors
- Uniform 32 KByte overlay blocks
- Uniform 64 KByte overlay blocks
• Fast Erase and Byte-Program:
- Chip-Erase Time: 35 ms (typical)
- Sector-/Block-Erase Time: 18 ms (typical)
- Byte-Program Time: 7 µs (typical)
• Auto Address Increment (AAI) Programming
The SST25VF016B device is offered in both 8-lead
SOIC (200 mils) and 8-contact WSON (6mm x 5mm)
packages. See Figure 2-1 for pin assignments.
