高速16K ×8双端口静态RAM HIGH-SPEED 16K x 8 DUAL-PORT STATIC RAM
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 memory system applications results in full-speed, 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
— IDT7006S
Active: 750mW typ.
Standby: 5mW typ.
— IDT7006L
Active: 750mW typ.
Standby: 1mW typ.
• 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 operation—2V data retention
• TTL-compatible, single 5V ±10% power supply
• Available in a 68-pin PGA, a 68-pin quad flatpack, a 68-pin PLCC, and a 64-pin TQFP
• Industrial temperature range –40°C to +85°C is available, tested to military electrical specifications
