SST25WF040B

4-Mbit 1.8V SPI Serial Flash

Features

Packages

• Single Voltage Read and Write Operations:

• 8-Lead SOIC (150 mils) and 8-Contact USON

(2 mm x 3 mm)

- 1.65V-1.95V

• Serial Interface Architecture:

- SPI Compatible: Mode 0 and Mode 3

• High-Speed Clock Frequency:

- 40 MHz

Product Description

SST25WF040B is a member of the Serial Flash 25

Series family and features a four-wire, SPI-compatible

interface that allows for a low pin count package which

occupies less board space and ultimately lowers total

system costs. SPI Serial Flash memory is

manufactured with proprietary, high-performance

CMOS SuperFlash^®technology. The split-gate cell

design and thick-oxide tunneling injector attain better

reliability and manufacturability compared with

alternate approaches.

• Dual Input/Output Support:

- Fast Read Dual Output Instruction (3BH)

- Fast Read Dual I/O Instruction (BBH)

• Superior Reliability:

- Endurance: 100,000 cycles

- Greater than 20 years data retention

• Ultra-Low Power Consumption:

- Active Read current: 4 mA (typical)

- Standby current: 7 µA (typical)

- Power-Down mode Standby current: 2 µA (typical)

• Flexible Erase Capability:

- Uniform 4-Kbyte sectors

This Serial Flash significantly improves performance

and reliability, while lowering power consumption. The

device writes (Program or Erase) with a single power

supply of 1.65V-1.95V. The total energy consumed is a

function of the applied voltage, current and time of

application. For any given voltage range, the

SuperFlash technology uses less current to program

and has a shorter erase time. As a result, the total

energy consumed during any Erase or Program

operation is less than alternative Flash memory

technologies.

- Uniform 64-Kbyte overlay blocks

• Page Program Mode:

- 256 bytes/page

• Fast Erase and Page Program:

- Chip Erase time: 400 ms (typical)

- Sector Erase time: 40 ms (typical)

- Block Erase time: 80 ms (typical)

- Page Program time: 0.8 ms/256 bytes (typical)

• End-of-Write Detection:

See Figure 2-1 for the pin assignments.

- Software polling the BUSY bit in STATUS

• Hold Pin (HOLD#):

- Suspend a serial sequence without deselecting the

device

• Write Protection (WP#):

- Enables/Disables the Lock-Down function of the

STATUS register

• Software Write Protection:

- Write protection through Block Protection bits in

STATUS register

• Temperature Range:

- Industrial: -40°C to +85°C

- Extended: -40°C to +125°C

• All devices are RoHS compliant
