AUGUST 2015 DSC 2939/14 I/O Control Address Decoder MEMORY ARRAY ARBITRATION SEMAPHORE LOGIC Address Decoder I/O Control R/WL BUSYL A13L A0L 2939 drw 01 UBL LBL CEL OEL I/O8L-I/O15L I/O0L-I/O7L CEL SEML M/ S R/WR BUSYR UBR LBR CER OER I/O8R-I/O15R I/O0R-I/O7R A13R A0R SEMR CER (1,2) (1,2) 14 14 HIGH-SPEED 16K X 16 DUAL-PORT STATIC RAM Features ◆ ◆ ◆ ◆ ◆ True Dual-Ported memory cells which allow simultaneous access of the same memory location ◆ ◆ ◆ ◆ ◆ High-speed access – Commercial: 15/20/25/35/55ns (max.) – Industrial: 20/25/35/55ns (max.) – Military: 20/25/35/55ns (max.) ◆ ◆ ◆ ◆ ◆ Low-power operation – IDT7026S Active: 750mW (typ.) Standby: 5mW (typ.) – IDT7026L Active: 750mW (typ.) Standby: 1mW (typ.) ◆ ◆ ◆ ◆ ◆ Separate upper-byte and lower-byte control for multi- plexed bus compatibility ◆ ◆ ◆ ◆ ◆ IDT7026 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 ◆ ◆ ◆ ◆ ◆ On-chip port arbitration logic ◆ ◆ ◆ ◆ ◆ Full on-chip hardware support of semaphore signaling between ports ◆ ◆ ◆ ◆ ◆ Fully asynchronous operation from either port ◆ ◆ ◆ ◆ ◆ TTL-compatible, single 5V (±10%) power supply ◆ ◆ ◆ ◆ ◆ Available in 84-pin PGA and 84-pin PLCC ◆ ◆ ◆ ◆ ◆ Industrial temperature range (-40°C to +85°C) is available for selected speeds ◆ ◆ ◆ ◆ ◆ Green parts available, see ordering information Functional Block Diagram IDT7026S/L NOTES: 1. (MASTER): BUSY is output; (SLAVE): BUSY is input. 2. BUSY outputs are non-tri-stated push-pull. |
