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 �A 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, ) 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°C, the TC554161AFTI can be used in environments exhibiting extreme
temperature conditions. The TC554161AFTI is available in a plastic 54-pin thin -small-outline package (TSOP).
FEATURES Low-power dissipation
Operating: 55 mW/MHz (typical) Single power supply voltage of 5 V � 10% Power down features using CE. Data retention supply voltage of 2 to 5.5 V Direct TTL compatibility for all inputs and outputs Wide operating temperature range of �40° to 85°C Standby Current (maximum):
