TC554161AFTI-70,-85,-10,-70L,-85L,-10L TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS 262,144-WORD BY 16-BIT STATIC RAM DESCRIPTION The TC554161AFTI is a 4,194,304-bit static random access memory (SRAM) organized as 262,144 words by 16bits. Fabricated using Toshiba's CMOS Silicon gate process technology, this device operates from a single 5V ± 10% power supply. Advanced circuit technology provides both high speed and low power at an operating current of 10 mA/MHz (typ) and a minimum cycle time of 70 ns. It is automatically placed in low-power mode at 2 mA standby current (typ) when chip enable ( CE ) is asserted high. There are two control inputs. CE is used to select the device and for data retention control, and output enable ( OE ) provides fast memory access. Data byte control pin ( LB , UB ) provides lower and upper byte access. This device is well suited to various microprocessor system applications where high speed, low power and battery backup are required. And, wi...
