IDT70T3519/99/89S
DUAL-PORT STATIC RAM
WITH 3.3V OR 2.5V INTERFACE
Features:
◆ ◆
access of the same memory location
Separate byte controls for multiplexed bus and bus
High-speed data access
matching compatibility
– Commercial: 3.4 (200MHz)/3.6ns (166MHz)/
4.2ns (133MHz)(max.)
– Industrial: 3.6ns (166MHz)/4.2ns (133MHz) (max.)
Dual Cycle Deselect (DCD) for Pipelined Output Mode
2.5V (±100mV) power supply for core
LVTTL compatible, selectable 3.3V (±150mV) or 2.5V
Selectable Pipelined or Flow-Through output mode
Counter enable and repeat features
(±100mV) power supply for I/Os and control signals on
each port
Dual chip enables allow for depth expansion without
additional logic
Full synchronous operation on both ports
– 5ns cycle time, 200MHz operation (14Gbps bandwidth)
– Fast 3.4ns clock to data out
– 1.5ns setup to clock and 0.5ns hold on all control, data, and
address inputs @ 200MHz
– Data input, address, byte enable and control registers
– Self-timed write allows fast cycle time
Industrial temperature range (-40°C to +85°C) is
available at 166MHz and 133MHz
Available in a 256-pin Ball Grid Array (BGA), a 208-pin
Plastic Quad Flatpack (PQFP) and 208-pin fine pitch Ball
Grid Array (fpBGA)
Supports JTAG features compliant with IEEE 1149.1
Due to limited pin count JTAG is not supported on the 208-
pin PQFP package
Green parts available, see ordering information

1. Address A 17 is a NC for the IDT70T3599. Also, Addresses A 17 and A 16 are NC's for the IDT70T3589.
2. The sleep mode pin shuts off all dynamic inputs, except JTAG inputs, when asserted. All static inputs, i.e., PL/ FT x and OPTx
and the sleep mode pins themselves (ZZx) are not affected during sleep mode.
