Product Description

SST25WF020A is a member of the Serial Flash 25

Series family and feature 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 manufac-

turability compared with alternate approaches.

• Superior Reliability

- Endurance: 100,000 Cycles

- Greater than 20 years Data Retention

• Ultra-Low Power Consumption:

- Active Read Current: 4 mA (typical)

- Standby Current: 10 µA (typical)

- Power-down Mode Standby Current: 4 µA (typical)

• Flexible Erase Capability

This Serial Flash significantly improve performance

and reliability, while lowering power consumption. The

device writes (Program or Erase) with a single power

supply of 1.65-1.95V. 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 con-

sumed during any Erase or Program operation is less

than alternative flash memory technologies.

- Uniform 4 KByte sectors

- Uniform 64 KByte overlay blocks

• Page Program Mode

- 256 Bytes/Page

• Fast Erase and Page-Program:

- Chip-Erase Time: 300 ms (typical)

- Sector-Erase Time: 40 ms (typical)

- Block-Erase Time: 80 ms (typical)

- Page-Program Time: 3 ms/ 256 bytes (typical)

• End-of-Write Detection

SST25WF020A is offered in 8-lead SOIC and 8-contact

USON packages. See Figure 2-1 for the pin assign-

ments.

- Software polling the BUSY bit in Status Register

• Hold Pin (HOLD#)

- Suspend a serial sequence without deselect-

ing 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
