HIGH-SPEED 4K x 9 DUAL-PORT STATIC RAM Integrated Device Technology, Inc. IDT7014S FEATURES: • True Dual-Ported memory cells which allow simultaneous access of the same memory location • High-speed access — Military: 20/25/35ns (max.) — Commercial: 12/15/20/25ns (max.) • Low-power operation — IDT7014S Active: 900mW (typ.) • Fully asynchronous operation from either port • TTL-compatible; single 5V (± 10%) power supply • Available in 52-pin PLCC and a 64-pin TQFP • Industrial temperature range (–40°C to +85°C) is available, tested to military electrical specifications DESCRIPTION: The IDT7014 is an extremely high-speed 4K x 9 Dual-Port Static RAM designed to be used in systems where on-chip hardware port arbitration is not needed. This part lends itself to high-speed applications which do not need on-chip arbitration to manage simultaneous access. The IDT7014 provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. See functional description. The IDT7014 utilitizes a 9-bit wide data path to allow for parity at the user's option. This feature is especially useful in data communication applications where it is necessary to use a parity bit for transmission/reception error checking. Fabricated using IDT’s high-performance technology, the IDT7014 Dual-Ports typically operate on only 900mW of power at maximum access times as fast as 12ns. The IDT7014 is packaged in a 52-pin PLCC and a 64-pin thin plastic quad flatpack (TQFP).
