IS65WV12816BLL-55BLA3

IS65WV12816ALL IS65WV12816BLL NOVEMBER 2007 128K x 16 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC RAM FEATURES DESCRIPTION The ISSI IS65WV12816ALL/ IS65WV12816BLL are high- High-speed access time: 55ns, 70ns speed, 2M bit static RAMs organized as 128K words by 16 CMOS low power operation: bits. It is fabricated using ISSI s high-performance CMOS 36 mW (typical) operating technology. This highly reliable process coupled with innovative circuit design techniques, yields high- 9 W (typical) CMOS standby performance and low power consumption devices. TTL compatible interface levels When CS1 is HIGH (deselected) or when CS2 is LOW Single power supply: (deselected) or when CS1 is LOW, CS2 is HIGH and both 1.65V to 2.2V VDD (65WV12816ALL) LB and UB are HIGH, the device assumes a standby mode 2.5V to 3.6V VDD (65WV12816BLL) at which the power dissipation can be reduced down with CMOS input levels. Fully static operation: no clock or refresh required Easy memory expansion is provided by using Chip Enable and Output Enable inputs. The active LOW Write Enable Three state outputs (WE) controls both writing and reading of the memory. A Data control for upper and lower bytes data byte allows Upper Byte (UB) and Lower Byte (LB) 2CS Option Available access. Temperature Offerings: The IS65WV12816ALL and IS65WV12816BLL are packged o in the JEDEC standard 48-pin mini BGA (6mm x 8mm) and Option A: 0 to 70 C 44-Pin TSOP (TYPE II). o Option A1: 40 to +85 C o Option A2: 40 to +105 C o Option A3: 40 to +125 C Lead-free available FUNCTIONAL BLOCK DIAGRAM 128K x 16 A0-A16 DECODER MEMORY ARRAY VDD GND I/O0-I/O7 I/O Lower Byte COLUMN I/O DATA CIRCUIT I/O8-I/O15 Upper Byte CS2 CS1 OE CONTROL CIRCUIT WE UB LB Copyright 2006 Integrated Silicon Solution, Inc.
