EM25LV010
1 Megabit (128K x 8) Serial Flash Memory
SPECIFICATION
General Description
The EM25LV010 is a 1 M bits Flash memory organized as 128K 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 EM25LV010 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. The
Hold pin, Write Protect pin, and Programmable Write Protect features provide flexible control.
The EM25LV010 is offered in 8-lead SO package and known good die (KGD). For KGD,
please contact ELAN Microelectronics or its representatives for detailed information (see
Appendix at the bottom of this specification for Ordering Information).
The EM25LV010 devices are suitable for applications that require memories with convenient
and economical updating of program, data or configurations, e.g., graphic cards, hard disk
drives, networking cards, digital camera printer, LCD monitors, cordless Phones, etc.
