STATIC RAM  
IDT7028L  
LEAD FINISH (SnPb) ARE IN EOL PROCESS - LAST TIME BUY EXPIRES JUNE 15, 2018  
Features  
True Dual-Ported memory cells which allow simultaneous  
M/S = VIH for BUSY output flag on Master,  
M/S = VIL for BUSY input on Slave  
Interrupt Flag  
On-chip port arbitration logic  
Full on-chip hardware support of semaphore signaling  
between ports  
Fully asynchronous operation from either port  
Separate upper-byte and lower-byte controls for multi-  
plexed bus and bus matching compatibility  
TTL-compatible, single 5V ( 10%) power supply  
Available in a 100-pin TQFP  
Industrial temperature range (–40°C to +85°C) is available  
for selected speeds  
Green parts available, see ordering information  
reads of the same memory location  
High-speed access  
– Commercial: 15/20ns (max.)  
– Industrial: 20ns (max.)  
Low-power operation  
– IDT7028L  
Active: 1W (typ.)  
Standby: 1mW (typ.)  
Dual chip enables allow for depth expansion without  
external logic  
IDT7028 easily expands data bus width to 32 bits or  
more using the Master/Slave select when cascading more  
than one device

NOTES:  
1. BUSY is an input as a Slave (M/S = VIL) and an output when it is a Master (M/S = VIH).  
2. BUSY and INT are non-tri-state totem-pole outputs (push-pull).
