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 CS# is HIGH (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. A data byte allows Upper Byte (UB#) and Lower Byte (LB#) access. The device is packaged in the JEDEC standard 48-Pin TSOP (TYPE I) and 48-pin mini BGA (6mm x 8mm).

SRAM has three different modes supported. Each function is described below with Truth Table. STANDBY MODE Device enters standby mode when deselected (CS# HIGH). The input and output pins (I/O0-15) are placed in a high impedance state. CMOS input in this mode will maximize saving power. WRITE MODE Write operation issues with Chip selected (CS#) and Write Enable (WE#) input LOW. The input and output pins (I/O015) are in data input mode. Output buffers are closed during this time even if OE# is LOW. UB# and LB# enables a byte write feature. By enabling LB# LOW, data from I/O pins (I/O0 through I/O7) are written into the location specified on the address pins. And with UB# being LOW, data from I/O pins (I/O8 through I/O15) are written into the location. READ MODE Read operation issues with Chip selected (CS# LOW) and Write Enable (WE#) input HIGH. When OE# is LOW, output buffer turns on to make data output. Any input to I/O pins during READ mode is not permitted. UB# and LB# enables a byte read feature. By enabling LB# LOW, data from memory appears on I/O0-7. And with UB# being LOW, data from memory appears on I/O8-15. In the READ mode, output buffers can be turned off by pulling OE# HIGH. In this mode, internal device operates as READ but I/Os are in a high impedance state. Since device is in READ mode, active current is used. POWER UP INITIALIZATION The device includes on-chip voltage sensor used to launch POWER-UP initialization process. When VDD reaches stable level, the device requires 150us of tPU (Power-Up Time) to complete its self-initialization process. When initialization is complete, the device is ready for normal operation. tPU 150 us Stable VDD Device Initialization VDD Device for Normal Operation 0V TRUTH TABLE Mode Not Selected Output Disabled Read Write CS# WE# OE# LB# UB# I/O0-I/O7 I/O8-I/O15 VDD Current H L L L L L L L L X H H H H H L L L X H H L L L X X X X L H L H L L H L X L L H L L H L L High-Z High-Z High-Z DOUT High-Z DOUT DIN High-Z DIN High-Z High-Z High-Z High-Z DOUT DOUT High-Z DIN DIN ISB1, ISB2 Integrated Silicon Solution, Inc.- www.issi.com Rev.
