The IDT7025 is a high-speed 8K x 16 Dual-Port Static RAM. The IDT7025 is designed to be used as a stand-alone 128K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit or more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 32-bit or wider memory system applications results in fullspeed, error-free operation without the need for additional discrete logic.
FEATURES:
• True Dual-Ported memory cells which allow simultaneous access of the same memory location
• High-speed access
— Military: 20/25/35/55/70ns (max.)
— Commercial: 15/17/20/25/35/55ns (max.)
• Low-power operation
— IDT7025S
Active: 750mW (typ.)
Standby: 5mW (typ.)
— IDT7025L
Active: 750mW (typ.)
Standby: 1mW (typ.)
• Separate upper-byte and lower-byte control for
multiplexed bus compatibility
• IDT7025 easily expands data bus width to 32 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
• Devices are capable of withstanding greater than 2001V
electrostatic discharge
• Fully asynchronous operation from either port
• Battery backup operation—2V data retention
• TTL-compatible, single 5V (±10%) power supply
• Available in 84-pin PGA, 84-pin quad flatpack, 84-pin
PLCC, and 100-pin Thin Quad Plastic Flatpack
• Industrial temperature range (–40°C to +85°C) is available,
tested to military electrical specifications
