524,288-WORD BY 18-BIT SYNCHRONOUS NO-TURNAROUND STATIC RAM
DESCRIPTION
The TC55WD818FF is a synchronous static random access memory(SRAM) organized as 524,288 words by 18
bits. NtRAMTM(no-turnaround) SRAM offers high bandwidth by e1iminating_dead cycles during the
transition from a read to a write and vice versa. All inputs except Output Enable OE and the Snooze pin ZZ
are synchronized with the rising edge of the CLK input. A Read operation is initiated b the ADV Address
Advanced Input signal ; the input from the address Fins and all control pins except the E and ZZ pins are
loaded into the internal registers on the rising edge 0 CLK in the cycle in which ADV is asserted. The output
data is available two clock c cles later. Write operations are internally self-timed and are initiated bly the
rising edgesfCLK in the eye e in which ADV is asserted. The input from' the address pins and all contro pins
except the OE and ZZ pins are loaded into the internal registers on the rising edge of CLK in the cycle in which
ADV is asserted. In ut data is loaded in the third cycle after the cycle in which ADV is asserted. Byte Write
Enables(BW1 to BW2) allow from one to four Byte Write operations to be performed. A 2-bit burst address
counter and control logic are integrated into this SRAM. The TC55WD818FF uses a single power supply
(2.5V) and is available in a 100-pin low-profile plastic QFP(LQFP).

PIN DESCRIPTIONS
PIN NUMBER SYMBOL TYPE DESCRIPTION
89 CLK Input Clock Input
(NA) All synchronous input signals are registered on
the rising edge of CLK. When the chip is
enabled, address inputs and control pins except
for E and 22 must meet the specified setup
and hold times with respect to the CLK rising
37, 36, 35, 34, 33, 32, A0 to A18 Input Address Inputs
100, 99,82, 81, 44, 45, (synchronous) These address inputs are registered on the rising
46, 47, 48, 49, 50, 83, 80 edge of CLK. When the chip is enabled,
address inputs must meet the specified setup
and hold times with respect to the CLK rising
98 E Input Chip Enable Input
(synchronous) This active-Low signal controls the chip status
(enabled or disabled). It is sampled only when
a new external address is loaded.
92 m Input Chip Enable Input
(synchronous) This active-Low signal controls the chip status
(enabled or disabled). It is sampled only when
a new external address is loaded.
97 CE2 Input Chip Enable Input
(synchronous) This active-high signal controls the chip status
(enabled or disabled). It is sampled only when
a new external address is loaded.
86 a Input Output Enable Input
(asynchronous) This active-Low signal controls all 18 bits of the
" output buffer.
88 W Input Write Enable Input
(synchronous) This active-Low input controls Read/Write
operations.
93, 94 W to m Input Byte Write Enable
(synchronous) These active-Low inputs control Byte Write
operations when a Write cycle is active. A Byte
Write pin controls l/O pins as follows.
B)/j1:I/O1 to |/09
Wn/ow to |/O18
85 ADV Input Address Advance Input
(synchronous) This is used to load the internal registers with
the input from the address and control signals
when it is Low on the rising edge of CLK.
When it is High, the internal burst address
counter is incremented. The external address
inputs are ignored when this signal is High.
87 m Input Clock Enable
(synchronous) When High, CLK input is ignored and outputs
retain the same state.

64 22 Input Snooze Input
(asynchronous) This active-High signal is used to place the
device into Sleep Mode(Low-Power Standby
Mode). When Low, the device remains in the
Active state. When High, the device goes into
the Sleep state and memory data is retained.
After this signal has been de-asserted, the
device will wake up when a read or write
operation is initiated by ADV.

2. A Deselect Continue cycle can only be entered if a Deselect cycle is executed before it.
3. When the Ignore Clock Edge command is asserted during a Read operation, the out ut data
for the prev1ous cycle still appear on the I/O pins. When the command is asserted uring a
Write operation, the I/O pins remain at Hi-Z and the Write operation is not executed.
4. All synchronous Inputs must exhibit adequate setup and hold times either side of the rising

NOTE : 1. Do not apply opposite data polarity to the I/O pins when they are in the output state.
2. Output enable and output disable times are specified as follows using the output load
shown in Fig. 1.

I. Input states are defined in the Synchronous Input Truth Table.
2. If the device was previously deselected, when the device is selected, the
output remains in a high impedance state in the present clock cycle
regardless of CT? because of the output enable delay register.
Valid data appears in the second clock cycle when UE is low.
3. When the device is deselected, the output goes into a high impedance
state in the next clock cycle regardless of (TE.
