SYNCHRONOUS PIPELINED
DUAL-PORT STATIC RAM
Features
IDT709359/49L
True Dual-Ported memory cells which allow simultaneous
access of the same memory location
High-speed clock to data access
– Commercial: 6.5/7.5/9ns (max.)
– Industrial: 7.5ns (max.)
Low-power operation
– IDT709359/49L
Active: 925mW (typ.)
Standby: 2.5mW (typ.)
Flow-Through or Pipelined output mode on either Port via
the
FT/PIPE
pins
Counter enable and reset features
Dual chip enables allow for depth expansion without
additional logic
Full synchronous operation on both ports
– 3.5ns setup to clock and 0ns hold on all control, data, and
address inputs
– Data input, address, and control registers
– Fast 6.5ns clock to data out in the Pipelined output mode
– Self-timed write allows fast cycle time
– 10ns cycle time, 100MHz operation in Pipelined output mode
Separate upper-byte and lower-byte controls for
multiplexed bus and bus matching compatibility
TTL- compatible, single 5V (±10%) power supply
Industrial temperature range (–40°C to +85°C) is
available for 83 MHz
