TC554161AFTI-70L

Product Summary

The TC554161AFTI-70L is a 4,194,304-bit static random access memory. The TC554161AFTI-70L 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. The TC554161AFTI-70L is automatically placed in low-power mode at 2 μA 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, with a guaranteed operating extreme temperature range of -40℃ to 85℃, the TC554161AFTI-70L can be used in environments exhibiting extreme temperature conditions. The TC554161AFTI-70L is available in a plastic 54-pin thin -small-outline package (TSOP).
