HIGH-SPEED
16K x 9 DUAL-PORT
STATIC RAM
IDT7016S/L
FEATURES:
• True Dual-Ported memory cells which allow simulta-
neous access of the same memory location
• High-speed access
— Military: 20/25/35ns (max.)
— Commercial:12/15/20/25/35ns (max.)
• Low-power operation
— IDT7016S
Active: 750mW (typ.)
Standby: 5mW (typ.)
— IDT7016L
Active: 750mW (typ.)
Standby: 1mW (typ.)
• IDT7016 easily expands data bus width to 18 bits or
more using the Master/Slave select when cascading
more than one device
• M/S = H for BUSY output flag on Master
M/S = L for BUSY input on Slave
FUNCTIONAL BLOCK DIAGRAM
• 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
• Devices are capable of withstanding greater than
2001V electrostatic discharge
• TTL-compatible, single 5V (±10%) power supply
• Available in ceramic 68-pin PGA, 68-pin PLCC, and
an 80-pin TQFP
• Industrial temperature range (–40°C to +85°C) is
available, tested to military electrical specifications
DESCRIPTION:
The IDT7016 is a high-speed 16K x 9 Dual-Port Static
RAMs. The IDT7016 is designed to be used as stand-
alone Dual-Port RAM or as a combination MASTER/
SLAVE Dual-Port RAM for 18-bit-or-more wider systems.

NOTES:
1. In MASTER mode: BUSY is an output and is a push-pull driver
In SLAVE mode: BUSY is input.
2. BUSY outputs and INT outputs are non-tri-stated push-pull drivers.

NOTES:
1. "X" in part numbers indicates power rating (S or L).
2. VCC = 5V, TA = +25°C, and are not production tested. ICCDC = 120mA(typ.)
3. At f = fMAX, address and I/Os are cycling at the maximum frequency read cycle of 1/tRC.
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 of port "A".

1. CE = VIH for the duration of the above timing (both write and read cycle).
2. "DATAOUT VALID" represents all I/O's (I/O0-I/O8) equal to the semaphore value.

NOTES:
1. DOR = DOL =VIH, CER = CEL =VIH.
2. All timing is the same for left and right ports. Port“A” may be either left or right port. “B” is the opposite port from “A”.
3. This parameter is measured from R/WA or SEM"A" going high to WR/ "B" or SEM"B" going High.
4. If tSPS is not satisfied, there is no guarantee which side will be granted the semaphore flag.
