IDT7132SA/LA  
IDT7142SA/LA  
HIGH-SPEED  
2K x 8 DUAL-PORT  
STATIC RAM  
Integrated Device Technology, Inc.  
FEATURES:  
DESCRIPTION:  
• High-speed access  
The IDT7132/IDT7142 are high-speed 2K x 8 Dual-Port  
Static RAMs. The IDT7132 is designed to be used as a stand-  
alone 8-bit Dual-Port RAM or as a “MASTER” Dual-Port RAM  
together with the IDT7142 “SLAVE” Dual-Port in 16-bit-or-  
more word width systems. Using the IDT MASTER/SLAVE  
Dual-Port RAM approach in 16-or-more-bit memory system  
applications results in full-speed, error-free operation without  
the need for additional discrete logic.  
— Military: 25/35/55/100ns (max.)  
— Commercial: 25/35/55/100ns (max.)  
— Commercial: 20ns only in PLCC for 7132  
• Low-power operation  
— IDT7132/42SA  
Active: 550mW (typ.)  
Standby: 5mW (typ.)  
— IDT7132/42LA  
Both devices provide two independent ports with separate  
control, address, and l/O pins that permit independent, asyn-  
chronousaccessforreadsorwritestoanylocationinmemory.  
An automatic power down feature, controlled by CE permits  
Active: 550mW (typ.)  
Standby: 1mW (typ.)  
• Fully asynchronous operation from either port  
• MASTER IDT7132 easily expands data bus width to 16-or- the on-chip circuitry of each port to enter a very low standby  
more bits using SLAVE IDT7142  
power mode.  
• On-chip port arbitration logic (IDT7132 only)  
• BUSY output flag on IDT7132; BUSY input on IDT7142  
• Battery backup operation —2V data retention  
• TTL-compatible, single 5V ±10% power supply  
• Available in popular hermetic and plastic packages  
• Military product compliant to MIL-STD, Class B  
• Standard Military Drawing # 5962-87002  
Fabricated using IDT’s CMOS high-performance technol-  
ogy, these devices typically operate on only 550mW of power.  
Low-power (LA) versions offer battery backup data retention  
capability, with each Dual-Port typically consuming 200µW  
from a 2V battery.  
The IDT7132/7142 devices are packaged in a 48-pin  
sidebraze or plastic DIPs, 48-pin LCCs, 52-pin PLCCs, and  
• Industrial temperature range (–40°C to +85°C) is available, 48-lead flatpacks. Military grade product is manufactured in  
tested to miliary electrical specifications  
compliance with the latest revision of MIL-STD-883, Class B,  
making it ideally suited to military temperature applications  
demanding the highest level of performance and reliability.
