HIGH-SPEED
8K x 18 DUAL-PORT
STATIC RAM
IDT7035S/L
Features
x True Dual-Ported memory cells which allow simultaneous
reads of the same memory location
x High-speed access
– Commercial: 15/20ns (max.)
x Low-power operation
– IDT7035S
Active: 800mW (typ.)
Standby: 5mW (typ.)
– IDT7035L
Active: 800mW (typ.)
Standby: 1mW (typ.)
x Separate upper-byte and lower-byte control for multiplexed
bus compatibility
x IDT7035 easily expands data bus width to 36 bits or more
using the Master/Slave select when cascading more than
one device
x M/S = H for BUSY output flag on Master
M/S = L for BUSY input on Slave
x Interrupt Flag
x On-chip port arbitration logic
x Full on-chip hardware support of semaphore signaling
between ports
x Fully asynchronous operation from either port
x Battery backup operation—2V data retention
x TTL-compatible, single 5V (±10%) power supply
x Available in 100-pin Thin Quad Flatpack
Industrial temperature range (–40°C to +85°C) is available
for selected speeds

1. 'X' in part numbers indicates power rating (S or L)
2. VCC = 5V, TA = +25°C, and are not production tested. Icc dc = 120mA (TYP)
3. At f = fMAX, address and I/O'S are cycling at the maximum frequency read cycle of 1/tRC, and using “AC Test Conditions” of input levels of
GND to 3V.
4. f = 0 means no address or control lines change.
5. Port "A" may be either left or right port. Port "B" is the opposite from port "A".
6. Industrial temperature: for specific speeds, packages and powers contact your sales office.
