TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOSꢀ
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, 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).

Note:
(1)
R/W remains HIGH for the read cycle.
(2)
(3)
(4)
(5)
If CE goes LOW coincident with or after R/W goes LOW, the outputs will remain at high impedance.
If CE goes HIGH coincident with or before R/W goes HIGH, the outputs will remain at high impedance.
If OE is HIGH during the write cycle, the outputs will remain at high impedance.
Because I/O signals may be in the output state at this time, input signals of reverse polarity must not be
applied.
