⢠IDT7006 easily expands data bus width to 16 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
⢠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
⢠Battery backup operationâ2V data retention

⢠Available in a 68-pin PGA, a 68-pin quad flatpack, a 68-
pin PLCC, and a 64-pin TQFP
⢠Industrial temperature range (â40°C to +85°C) is avail-
able, tested to military electrical specifications
DESCRIPTION:
The IDT7006 is a high-speed 16K x 8 Dual-Port Static
RAM. The IDT7006 is designed to be used as a stand-alone
Dual-Port RAM or as a combination MASTER/SLAVE Dual-
Port RAM for 16-bit-or-more word systems. Using the IDT
MASTER/SLAVE Dual-Port RAM approach in 16-bit or wider
