Functional Description

[1]

The CY7C1381D/CY7C1383D/CY7C1381F/CY7C1383F is a

3.3V, 512K x 36 and 1M x 18 synchronous flow through
SRAMs, designed to interface with high-speed
microprocessors with minimum glue logic. Maximum access
delay from clock rise is 6.5 ns (133 MHz version). A 2-bit
on-chip counter captures the first address in a burst and
increments the address automatically for the rest of the burst
access. All synchronous inputs are gated by registers
controlled by a positive edge triggered clock input (CLK). The
synchronous inputs include all addresses, all data inputs,
address pipelining chip enable (CE
enables (CE2 and CE

[2]

), burst control inputs (ADSC, ADSP,

3

), depth-expansion chip

1

and ADV), write enables (BWx, and BWE), and global write

). Asynchronous inputs include the output enable (OE)

(GW
and the ZZ pin.

The CY7C1381D/CY7C1383D/CY7C1381F/CY7C1383F
allows interleaved or linear burst sequences, selected by the
MODE input pin. A HIGH selects an interleaved burst
sequence, while a LOW selects a linear burst sequence. Burst
accesses can be initiated with the processor address strobe

) or the cache controller address strobe (ADSC) inputs.

(ADSP
Address advancement is controlled by the address
advancement (ADV) input.

Addresses and chip enables are registered at rising edge of
clock when address strobe processor (ADSP) or address
strobe controller (ADSC) are active. Subsequent burst
addresses can be internally generated as controlled by the
advance pin (ADV

).

The CY7C1381D/CY7C1383D/CY7C1381F/CY7C1383F
operates from a +3.3V core power supply while all outputs
operate with a +2.5V or +3.3V supply. All inputs and outputs
are JEDEC-standard and JESD8-5-compatible.

The CY7C1381D/CY7C1383D/CY7C1381F/CY7C1383F
supports secondary cache in systems utilizing a linear or
interleaved burst sequence. The interleaved burst order
supports Pentium

®

and i486™ processors. The linear burst
sequence is suited for processors that utilize a linear burst
sequence. The burst order is user selectable, and is
determined by sampling the MODE input. Accesses can be
initiated with the processor address strobe (ADSP

) or the
controller address strobe (ADSC). Address advancement
through the burst sequence is controlled by the ADV input. A
two-bit on-chip wraparound burst counter captures the first
address in a burst sequence and automatically increments the
address for the rest of the burst access.

Byte write operations are qualified with the byte write enable

Burst Sequences

The CY7C1381D/CY7C1383D/CY7C1381F/CY7C1383F
provides an on-chip two-bit wraparound burst counter inside
the SRAM. The burst counter is fed by A

, and can follow

[1:0]

either a linear or interleaved burst order. The burst order is
determined by the state of the MODE input. A LOW on MODE
will select a linear burst sequence. A HIGH on MODE will
select an interleaved burst order. Leaving MODE unconnected
will cause the device to default to a interleaved burst
sequence.

Sleep Mode

The ZZ input pin is an asynchronous input. Asserting ZZ
places the SRAM in a power conservation sleep mode. Two
clock cycles are required to enter into or exit from this sleep
mode. While in this mode, data integrity is guaranteed.
Accesses pending when entering the sleep mode are not
considered valid nor is the completion of the operation

IEEE 1149.1 Serial Boundary Scan (JTAG)

The CY7C1381D/CY7C1383D/CY7C1381F/CY7C1383F
incorporates a serial boundary scan test access port
(TAP).This part is fully compliant with 1149.1. The TAP
operates using JEDEC-standard 3.3V or 2.5V IO logic levels.

The CY7C1381D/CY7C1383D/CY7C1381F/CY7C1383F
contains a TAP controller, instruction register, boundary scan
register, bypass register, and ID register.

Disabling the JTAG Feature

It is possible to operate the SRAM without using the JTAG
feature. To disable the TAP controller, TCK must be tied LOW
(V

) to prevent clocking of the device. TDI and TMS are

instruction that is loaded into the TAP instruction register. TDI
is internally pulled up and can be unconnected if the TAP is
unused in an application. TDI is connected to the most
significant bit (MSB) of any register. (See TAP Controller Block

Diagram.)

Test Data-Out (TDO)

The TDO output ball is used to serially clock data-out from the
registers. The output is active depending upon the current
state of the TAP state machine. The output changes on the
falling edge of TCK. TDO is connected to the least significant
bit (LSB) of any register. (See TAP Controller State Diagram.)

TAP Registers

Registers are connected between the TDI and TDO balls and
allow data to be scanned in and out of the SRAM test circuitry.
Only one register can be selected at a time through the
instruction registers. Data is serially loaded into the TDI ball on
the rising edge of TCK. Data is output on the TDO ball on the
falling edge of TCK.

Instruction Register

Three-bit instructions can be serially loaded into the instruction
register. This register is loaded when it is placed between the
TDI and TDO balls as shown in the TAP Controller Block

Diagram. Upon power up, the instruction register is loaded

with the IDCODE instruction. It is also loaded with the IDCODE
instruction if the controller is placed in a reset state as
described in the previous section.

When the TAP controller is in the Capture-IR state, the two
least significant bits are loaded with a binary ‘01’ pattern to
allow for fault isolation of the board level serial test path.

Bypass Register

To save time when serially shifting data through registers, it is
sometimes advantageous to skip certain chips. The bypass
register is a single-bit register that can be placed between the
TDI and TDO balls. This allows data to be shifted through the
SRAM with minimal delay. The bypass register is set LOW
(V

) when the BYPASS instruction is executed.

SS

Boundary Scan Register

The boundary scan register is connected to all the input and
bidirectional balls on the SRAM.

The boundary scan register is loaded with the contents of the
RAM input and output ring when the TAP controller is in the
Capture-DR state and is then placed between the TDI and
TDO balls when the controller is moved to the Shift-DR state.
The EXTEST, SAMPLE/PRELOAD, and SAMPLE Z
instructions can be used to capture the contents of the input
and output ring.

The boundary scan order tables show the order in which the
bits are connected. Each bit corresponds to one of the bumps
on the SRAM package. The MSB of the register is connected
to TDI, and the LSB is connected to TDO.

Identification (ID) Register

The ID register is loaded with a vendor-specific 32-bit code
during the Capture-DR state when the IDCODE command is
loaded in the instruction register. The IDCODE is hardwired
into the SRAM and can be shifted out when the TAP controller
is in the Shift-DR state. The ID register has a vendor code and
other information described in Identification Register

Definitions on page 15.

TAP Instruction Set

Overview

Eight different instructions are possible with the three bit
instruction register. All combinations are listed in Identification

Codes on page 15. Three of these instructions are listed as

RESERVED and must not be used. The other five instructions
are described in detail below.

Instructions are loaded into the TAP controller during the
Shift-IR state, when the instruction register is placed between
TDI and TDO. During this state, instructions are shifted
through the instruction register through the TDI and TDO balls.
To execute the instruction once it is shifted in, the TAP
controller needs to be moved into the Update-IR state.

EXTEST

The EXTEST instruction enables the preloaded data to be
driven out through the system output pins. This instruction also
selects the boundary scan register to be connected for serial
access between the TDI and TDO in the Shift-DR controller
state.

IDCODE

The IDCODE instruction causes a vendor-specific 32-bit code
to be loaded into the instruction register. It also places the
instruction register between the TDI and TDO balls and allows
the IDCODE to be shifted out of the device when the TAP
controller enters the Shift-DR state.

The IDCODE instruction is loaded into the instruction register
upon power up or whenever the TAP controller is given a test
logic reset state.

SAMPLE Z

The SAMPLE Z instruction causes the boundary scan register
to be connected between the TDI and TDO balls when the TAP
controller is in a Shift-DR state. The SAMPLE Z command
places all SRAM outputs into a High-Z state.

SAMPLE/PRELOAD

SAMPLE/PRELOAD is a 1149.1 mandatory instruction. When
the SAMPLE/PRELOAD instructions are loaded into the
instruction register and the TAP controller is in the Capture-DR
state, a snapshot of data on the inputs and output pins is
captured in the boundary scan register.

The user must be aware that the TAP controller clock can only
operate at a frequency up to 20 MHz, while the SRAM clock
operates more than an order of magnitude faster. Because
there is a large difference in the clock frequencies, it is
possible that during the Capture-DR state, an input or output
will undergo a transition. The TAP may then try to capture a
signal while in transition (metastable state). This will not harm
the device, but there is no guarantee as to the value that will
be captured. Repeatable results may not be possible.

To guarantee that the boundary scan register will capture the
correct value of a signal, the SRAM signal must be stabilized
long enough to meet the TAP controller's capture setup plus
hold times (t
captured correctly if there is no way in a design to stop (or
slow) the clock during a SAMPLE/PRELOAD instruction. If this
is an issue, it is still possible to capture all other signals and
simply ignore the value of the CK and CK
boundary scan register.

Once the data is captured, it is possible to shift out the data by
putting the TAP into the Shift-DR state. This places the
boundary scan register between the TDI and TDO pins.

PRELOAD allows an initial data pattern to be placed at the
latched parallel outputs of the boundary scan register cells
prior to the selection of another boundary scan test operation.

The shifting of data for the SAMPLE and PRELOAD phases
can occur concurrently when required; that is, while data
captured is shifted out, the preloaded data is shifted in.

BYPASS

When the BYPASS instruction is loaded in the instruction
register and the TAP is placed in a Shift-DR state, the bypass
register is placed between the TDI and TDO balls. The
advantage of the BYPASS instruction is that it shortens the
boundary scan path when multiple devices are connected
together on a board.

EXTEST Output Bus Tri-State

IEEE standard 1149.1 mandates that the TAP controller be
able to put the output bus into a tri-state mode.

The boundary scan register has a special bit located at bit #85
(for 119-BGA package) or bit #89 (for 165-fBGA package).
When this scan cell, called the “extest output bus tri-state,” is
latched into the preload register during the Update-DR state in
the TAP controller, it will directly control the state of the output

and tCH). The SRAM clock input might not be

instruction. When HIGH, it will enable the output buffers to
drive the output bus. When LOW, this bit will place the output
bus into a High-Z condition.

This bit can be set by entering the SAMPLE/PRELOAD or
EXTEST command, and then shifting the desired bit into that
cell, during the Shift-DR state. During Update-DR, the value
loaded into that shift-register cell will latch into the preload
register. When the EXTEST instruction is entered, this bit will
