SA25F020 General Description

The SA25F020 is a 2Mb (512K X 4) CMOS non-volatile serial Flash Memory. This device fully conforms to the SPI 4-wire
protocol, is enabled through the Chip Select (CSb) pin, and uses Clock (SCK), Data-in (SI) and Data-out (SO) pins to
synchronously control data transfer between the SPI microcontroller and the Serial FLASH memory.

The memory can be programmed from 1 up to 256 bytes at a time via the Page Program (PP) instruction.

The memory is organized into four sectors. Each sector contains 256 pages, with each page being 256 bytes wide. The entire memory can therefore be viewed as consisting of 1024 pages, or 262,144 bytes.

The memory can be erased in one of the following ways:
• 256 bytes at a time, using the Page Erase (PE) instruction
• 512 Kb at a time, using the Sector Erase (SE) instruction
• 2 Mb at a time, using the Bulk Erase (BE) instruction

Each device requires only a 3.0V power supply (2.7 V to 3.6 V) for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. The SA25F020 does not require a VPP supply.

The HOLDb pin may be used to suspend any serial communication without resetting the serial sequence. In addition, the serial interface allows a minimal-pin-count packaging designed to simplify PC board layout requirements and offers the designer a variety of low-voltage and low-power options.

The SA25F020 is available in a space-saving, 8-lead narrow SOIC package The SA25F020 is part of the SPI Flash and
EEPROM family. It is designed to work with any SPI-compatible, high-speed microcontroller, and offers both hardware
(WPb pin) and Software ("block protect") data protection. For example, programming a 2-bit code into the status register prevents program with top ¼, top ½ or entire array write protection and enables block write protection. Separate program enable and program disable instructions are provided for additional data protection. Hardware
data protection is provided via the WPb pin to protect against inadvertent write attempts to the status register.

Saifun's SPI Serial Flash products are designed and tested for applications requiring high endurance and low power
consumption for a continuously reliable non-volatile solution for all markets.
