General Description

The EM25LV512 is a 512K bits Flash memory organized as 64K x 8 bits and uses a single voltage of 2.7-3.6V for Program and Erase. It features a typical 2ms Page-Program time and a typical 40ms Block-Erase time. The device uses status register to detect the completion of the Program or Erase operation. To protect against inadvertent write, the device has on-chip hardware and software data protection schemes. The device offers typical 100,000 cycles endurance and a greater than 10 years data retention. The EM25LV512 conforms to SPI Bus compatible Serial Interface. It consisted of four pins (serial clock, chip select, serial data in, and serial data out) that support high-speed serial data transfers of up to 33MHz.
