TC55VZM216AJJN/AFTN08,10,12
TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS
262,144-WORD BY 16-BIT CMOS STATIC RAM
DESCRIPTION
The TC55VZM216AJJN/AFTN is a 4,194,304-bit high-speed static random access memory (SRAM) organized as
262,144 words by 16 bits. Fabricated using CMOS technology and advanced circuit techniques to provide high
speed, it operates from a single 3.3 V power supply. Chip enable ( CE ) can be used to place the device in a
low-power mode, and output enable ( OE ) provides fast memory access. Data byte control signals ( LB , UB ) provide
lower and upper byte access. This device is well suited to cache memory applications where high-speed access and
high-speed storage are required. All inputs and outputs are directly LVTTL compatible. The
TC55VZM216AJJN/AFTN is available in plastic 44-pin SOJ and TSOP with 400mil width for high density surface
assembly.

TC55VZM216AJJN/AFTN08:8 ns
TC55VZM216AJJN/AFTN10:10 ns
TC55VZM216AJJN/AFTN12:12 ns
Low-power dissipation (IDDO2)
(the following are maximum values)
Cycle Time
8 10 12 ns
Operation (max) 140 130 120
