IDT7024S/L  
HIGH-SPEED  
4K x 16 DUAL-PORT  
STATIC RAM  
Integrated Device Technology, Inc.  
more than one device  
FEATURES:  
• M/S = H for BUSY output flag on Master  
M/S = L for BUSY input on Slave  
• Busy and Interrupt Flags  
• On-chip port arbitration logic  
• Full on-chip hardware support of semaphore signaling  
between ports  
• True Dual-Ported memory cells which allow simulta-  
neous access of the same memory location  
• High-speed access  
— Military: 20/25/35/55/70ns (max.)  
— Commercial: 15/17/20/25/35/55ns (max.)  
• Low-power operation  
• Devices are capable of withstanding greater than 2001V  
electrostatic discharge.  
— IDT7024S  
Active: 750mW (typ.)  
• Fully asynchronous operation from either port  
• Battery backup operation—2V data retention  
• TTL-compatible, single 5V (±10%) power supply  
• Available in 84-pin PGA, 84-pin quad flatpack, 84-pin  
PLCC, and 100-pin Thin Quad Plastic Flatpack  
• Industrial temperature range (–40°C to +85°C) is avail-  
able, tested to military electrical specifications  
Standby: 5mW (typ.)  
— IDT7024L  
Active: 750mW (typ.)  
Standby: 1mW (typ.)  
• Separate upper-byte and lower-byte control for  
multiplexed bus compatibility  
• IDT7024 easily expands data bus width to 32 bits or  
more using the Master/Slave select when cascading
