| IS62WV2568ALL IS62WV2568BLL 256K 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 - 9 W (typical) CMOS standby * TTL compatible interface levels * Single power supply - 1.65V--2.2V VCC (62WV2568ALL) - 2.5V--3.6V VCC (62WV2568BLL) * Fully static operation: no clock or refresh required * Three state outputs * Industrial temperature available * Lead-free available ISSI JUNE 2005 (R) DESCRIPTION The ISSI IS62WV2568ALL / IS62WV2568BLL are highspeed, 2M bit static RAMs organized as 256K 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 highperformance and low power consumption devices. When CS1 is HIGH (deselected) or when CS2 is LOW (deselected) or when CS1 is LOW, CS2 is HIGH, 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 IS62WV2568ALL and IS62WV2568BLL are packaged in the JEDEC standard 32-pin TSOP (TYPE I), sTSOP (TYPE I), and 36-pin mini BGA.

Test conditions assume signal transition times of 5 ns or less, timing reference levels of 0.9V, input pulse levels of 0.4V to 1.4V and output loading specified in Figure 1. 2. The internal write time is defined by the overlap of CS1 LOW, CS2 HIGH and WE LOW. All signals must be in valid states to initiate a Write, but any one can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced to the rising or falling edge of the signal that terminates the write. 3. Tested with the load in Figure 2.
