The Pm25LV512/010 are 512 Kbit/1 Mbits 3.0 Volt-only serial Flash memories. These devices are designed to use a single low voltage, range from 2.7 Volt to 3.6 Volt, power supply to perform read, erase and program operations. The devices can be programmed in standard EPROM programmers as well. The device is optimized for use in many commercial applications where low-power and low-voltage operation are essential. The Pm25LV512/010 is enabled through the Chip Enable pin (CE#) and accessed via a 3-wire interface consisting of Serial Data Input (Sl), Serial Data Output (SO), and Serial Clock (SCK). All write cycles are completely self-timed. Block Write protection for top 1/4, top 1/2 or the entire memory array (1M) or entire memory array (512K) is enabled by programming the status register. Separate write enable and write disable instructions are provided for additional data protection. Hardware data protection is provided via the WP pin to protect against inadvertent write attempts to the status register. The HOLD pin may be used to suspend any serial communication without resetting the serial sequence. The Pm25LV512/010 are manufactured on PMC's advanced nonvolatile CMOS technology, P-FLASHTM. The devices are offered in 8-pin JEDEC SOIC and 8-contact WSON packages with operation frequency to 25 MHz.
