Functional Block Diagram
M/
S = VIH for BUSY output flag on Master,
M/
S = VIL for BUSY input on Slave
Busy and Interrupt Flags
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
LVTTL-compatible, single 3.3V (±0.3V) power supply
Available in a 100-pin TQFP
Industrial temperature range (–40°C to +85°C) is available
for selected speeds
Features
True Dual-Ported memory cells which allow simultaneous
access of the same memory location
High-speed access
– Commercial: 15/20ns (max.)
– Industrial: 20ns (max.)
Low-power operation
– IDT70V28L
Active: 440mW (typ.)
Standby: 660µW (typ.)
Dual chip enables allow for depth expansion without
external logic
IDT70V28 easily expands data bus width to 32 bits or
more using the Master/Slave select when cascading more
than one device
HIGH-SPEED 3.3V
64K x 16 DUAL-PORT
STATIC RAM
IDT70V28L
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).
