IS63WV1288DALL/DALS IS63WV1288DBLL/DBLS IS64WV1288DBLL/DBLS JUNE 2021 128K x 8 HIGH-SPEED CMOS STATIC RAM FEATURES DESCRIPTION HIGH SPEED: (IS63/64WV1288DALL/DBLL) The ISSI IS63/64WV1288Dxxx is a very high-speed, low power, 131,072-word by 8-bit CMOS static RAM. High-speed access time: 8, 10, 12, 20 ns The IS63/64WV1288DBLL is fabricated using ISSI s Low Active Power: 135 mW (typical) high-performance CMOS technology. This highly reliable Low Standby Power: 12 W (typical) process coupled with innovative circuit design CMOS standby techniques, yields higher performance and low power LOW POWER: (IS63/64WV1288DALS/DBLS) consumption devices. High-speed access time: 25, 35 ns When CE is HIGH (deselected), the device assumes a Low Active Power: 55 mW (typical) standby mode at which the power dissipation can be re- duced down to 25 W (typical) with CMOS input levels. Low Standby Power: 12 W (typical) CMOS standby The IS63/64WV1288DBLL operates from a single Vdd Single power supply power supply. The IS63/64WV1288Dxxx is available in 32-pin TSOP (Type II), 32-pin sTSOP (Type I), 48-Ball Vdd 1.65V to 2.2V (IS63WV1288DAxx) miniBGA (6mm x 8mm) and 32-pin SOJ (300-mil) pack- Vdd 2.4V to 3.6V (IS63/64WV1288DBxx) ages. Multiple center power and ground pins for greater noise immunity Easy memory expansion with CE and OE options CE power-down Fully static operation: no clock or refresh required TTL compatible inputs and outputs Lead-free available FUNCTIONAL BLOCK DIAGRAM 128K X 8 A0-A16 DECODER MEMORY ARRAY VDD GND I/O COLUMN I/O I/O0-I/O7 DATA CIRCUIT CE CONTROL OE CIRCUIT WE Copyright 2021 Integrated Silicon Solution, Inc.
