Functional Block Diagram
Features:
x
True Dual-Ported memory cells which allow simultaneous
access of the same memory location
x
High-speed clock to data access
– Commercial: 7.5/9/12ns (max.)
x
Low-power operation
– IDT70V9379L
Active: 500mW (typ.)
Standby: 1.5mW (typ.)
x
Flow-Through or Pipelined output mode on either port via
the
FT/PIPE pins
x
Counter enable and reset features
x
Dual chip enables allow for depth expansion without
additional logic
x
Full synchronous operation on both ports
– 4ns setup to clock and 0ns hold on all control, data, and
address inputs
– Data input, address, and control registers
– Fast 7.5ns clock to data out in the Pipelined output mode
– Self-timed write allows fast cycle time
– 12ns cycle time, 83MHz operation in Pipelined output mode
x
Separate upper-byte and lower-byte controls for
multiplexed bus and bus matching compatibility
x
LVTTL- compatible, single 3.3V (±0.3V) power supply
x
Industrial temperature range (–40°C to +85°C) is
available for selected speeds
x
Available in a 128-pin Thin Quad Flatpack (TQFP)
