IS62WV10248BLL www.DataSheet4U.com ISSI MARCH 2006 ® 1M x 8 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC RAM FEATURES • High-speed access time: 55ns, 70ns • CMOS low power operation: 36 mW (typical) operating 12 µW (typical) CMOS standby • TTL compatible interface levels • Single power supply: 2.5V--3.6V VDD (IS62WV10248BLL) • Fully static operation: no clock or refresh required • Three state outputs • Industrial temperature available • Lead-free available DESCRIPTION The ISSI IS62WV10248BLL is a high-speed, 8M bit static RAMs organized as 1M words by 8 bits. It is fabricated using ISSI's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields high-performance and low power consumption devices. When CS1 is HIGH (deselected) or when CS2 is LOW (deselected), the device assumes a standby mode at which the power dissipation can be reduced down with CMOS input levels. Easy memory expansion is provided by using Chip Enable and Output Enable inputs. The active LOW Write Enable (WE) controls both writing and reading of the memory. The IS62WV10248BLL is packaged in the JEDEC standard 48-pin mini BGA (7.2mm x 8.7mm).
