2mb Eeprom With 25mhz Spi Bus Interface

The SA25C020 is a 2Mb (512K X 4) CMOS non-volatile serial EEPROM 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 EEPROM The memory CAN be written from 1 up to 256 bytes at a time via the Byte / Page Write (PW) instruction. The memory consists of 1024 pages or 262,144 bytes. 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 SA25C020 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 SA25C020 is available in a space-saving, 8-lead narrow SOIC package The SA25C020 is part of the SPI 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 , top 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 By Unkown
