MAY 2000 DSC 3198/6 I/O Control Address Decoder 64Kx8 MEMORY ARRAY 7008 ARBITRATION INTERRUPT SEMAPHORE LOGIC CE0L OEL R/ W L A15L A0L I/O0-7L SEML INTL (2) BUSYL (1,2) R/ WL CE0L OEL I/O Control Address Decoder OER R/ WR CE0R A15R A0R I/O0-7R SEMR INTR (2) R BUSY (1,2) M/ S (1) CE1L R/ WR CE0R OER CE1R 3198 drw 01 1L CE 1R CE 16 16 Functional Block Diagram x IDT7008 easily expands data bus width to 16 bits or more using the Master/Slave select when cascading more than one device x M/ S = VIH for BUSY output flag on Master, M/ S = VIL 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 TTL-compatible, single 5V (±10%) power supply x Available in 84-pin PGA, 84-pin PLCC, and a 100-pin TQFP x Industrial temperature range (–40°C to +85°C) is available for selected speeds Features x True Dual-Ported memory cells which allow simultaneous reads of the same memory location x High-speed access – Military: 25/35/55ns (max.) – Industrial: 55ns (max.) – Commercial: 20/25/35/55ns (max.) x Low-power operation – IDT7008S Active: 750mW (typ.) Standby: 5mW (typ.) – IDT7008L Active: 750mW (typ.) Standby: 1mW (typ.) x Dual chip enables allow for depth expansion without external logic HIGH-SPEED 64K x 8 DUAL-PORT STATIC RAM IDT7008S/L NOTES: 1. BUSY is an input as a Slave (M/S = VIL) and an output when it is a Master (M/S = VIH). 2. BUSY and INT are non-tri-state totem-pole outputs (push-pull). |
