CY7C036A集成電路（IC）的存儲(chǔ)器規(guī)格書(shū)PDF中文資料

Functional Description

The CY7C026A and CY7C036A are low-power CMOS 16K x 16/18 dual-port static RAMs. Various arbitration schemes are included on the devices to handle situations when multiple processors access the same piece of data. Two ports are provided, permitting independent, asynchronous access for reads and writes to any location in memory.

Features

? True dual-ported memory cells that allow simultaneous access of the same memory location

? 16K x 16 organization (CY7C026A)

? 16K x 18 organization (CY7C036A)

? 0.35-micron CMOS for optimum speed/power

? High-speed access: 12[1]/15/20 ns

? Low operating power

— Active: ICC = 180 mA (typical)

— Standby: ISB3 = 0.05 mA (typical)
