Advance Information

4M Late Write HSTL

The MCM69L736A/818A is a 4M synchronous late write fast static RAM

designed to provide high performance in secondary cache and ATM switch,

Telecom, and other high speed memory applications. The MCM69L818A

(organized as 256K words by 18 bits) and the MCM69L736A (organized as 128K

words by 36 bits) are fabricated in Motorola’s high performance silicon gate

BiCMOS technology.

The differential clock (CK) inputs control the timing of read/write operations of

theRAM. AttherisingedgeofCK, alladdresses, writeenables, andsynchronous

selects are registered. An internal buffer and special logic enable the memory to

accept write data on the rising edge of CK a cycle after address and control

signals. Read data is available at the falling edge of CK.

ZP PACKAGE

PBGA

CASE 999–01

The RAM uses HSTL inputs and outputs. The adjustable input trip–point (V

)

ref

and output voltage (V

) gives the system designer greater flexibility in

DDQ

optimizing system performance.

The synchronous write and byte enables allow writing to individual bytes or the

entire word.

The impedance of the output buffers is programmable, allowing the outputs to

match the impedance of the circuit traces which reduces signal reflections.

ABSOLUTE MAXIMUM RATINGS (Voltages Referenced to V , See Note 1)

SS

This device contains circuitry to protect the

inputs against damage due to high static volt-

ages or electric fields; however, it is advised

that normal precautions be taken to avoid

application of any voltage higher than maxi-

mum rated voltages to this high–impedance

circuit.

This BiCMOS memory circuit has been

designed to meet the dc and ac specifications

shown in the tables, after thermal equilibrium

has been established.

TIMING LIMITS

The table of timing values shows either a minimum or a

maximum limit for each parameter. Input requirements are

specified from the external system point of view. Thus, ad-

dress setup time is shown as a minimum since the system

must supply at least that much time. On the other hand, re-

sponses from the memory are specified from the device

pointofview.Thus,theaccesstimeisshownasamaximum

since the device never provides data later than that time.

FUNCTIONAL OPERATION

READ AND WRITE OPERATIONS

All control signals except G are registered on the rising

edge of CK. These signals must meet the setup and hold

times shown in the AC Characteristics table. On the falling

edge of the current cycle, the output latch becomes trans-

parent and data is available. The output data is latched on

the rising edge of the next clock. The output data is available

LATE WRITE

The write address is sampled on the first rising edge of

clock, and write data is sampled on the following rising edge.

The late write feature is implemented with single stage

write buffering. Write buffering is transparent to the user. A

comparator monitors the address bus and, when necessary,

routes buffer contents to the outputs to ensure coherent op-

eration. This occurs in all cases whether there is a byte write

or a full word is written.

The designer can program the RAMs output buffer imped-

G, SS, and SW control output drive. Chip deselect via a

immediately (on the same cycle). Output selecting via a low

on SS and high on SW at a rising CK has its effect on the

ance by terminating the ZQ pin to V

through a precision

SS

resistor (RQ). The value of RQ is five times the output imped-

ance desired. For example, 250 Ω resistor will give an output

impedance of 50 Ω.

Impedance updates occur continuously and the frequency

of the update is based on the subdivided K clock. Note that if

the K clock stops so does the impedance update.

The actual change in the impedance occurs in small incre-

ments and is monotonic. There are no significant distur-

bances that occur on the output because of this smooth

The impedance update is not related to any particular type

of cycle because the impedance is updated continuously and

is based on the K clock. Updates occur regardless of wheth-

er the the device is performing a read, write or a deselect

cycle and does not depend on the state of G.

At power up, the output impedance defaults to approxi-

mately 50 ohms. It will take 4,000 to 16,000 cycles for the im-

pedance to be completely updated if the programmed

impedance is much higher or lower than 50 Ω.

WRITE AND BYTE WRITE FUNCTIONS

Note that in the following discussion the term “byte” refers

to nine bits of the RAM I/O bus. In all cases, the timing pa-

rameters described for synchronous write input (SW) apply

to each of the byte write enable inputs (SBa, SBb, etc.).

Byte write enable inputs have no effect on read cycles.

This allows the system designer not interested in performing

byte writes to connect the byte enable inputs to active low

(V ). Reads of all bytes proceed normally and write cycles,

having to drive multiple write input buffer loads.

POWER UP AND INITIALIZATION

Byte writes are performed using the byte write enable in-

puts in conjunction with the synchronous write input (SW). It

is important to note that writing any one byte will inhibit a read

of all bytes at the current address. The RAM cannot simulta-

neously read one byte and write another at the same ad-

dress. A write cycle initiated with none of the byte write

Once supplies have reached specification levels, a

minimum dwell of 1.0 µs with CK inputs cycling is required

before beginning normal operations. At power up the output

impedance will be set at approximately 50 Ω, however, in

order to match the programmed impedance the part requires

deselect cycles to occur.

SERIAL BOUNDARY SCAN TEST ACCESS PORT OPERATION

OVERVIEW

compliant TAPs. The TAP operates using conventional

JEDEC Standard 8–1B low voltage (3.3 V) TTL/CMOS logic

level signaling.

The serial boundary scan test access port (TAP) on this

RAM is designed to operate in a manner consistent with

IEEE 1149.1–1990 (commonly referred to as JTAG), but

does not implement all of the functions required for 1149.1

compliance. Certain functions have been modified or elimi-

nated because their implementation places extra delays in

the RAMs critical speed path. Nevertheless, the RAM sup-

ports the standard TAP controller architecture. The TAP con-

troller is the state machine that controls the TAP operation

and can be expected to function in a manner that does not

conflict with the operation of devices with IEEE 1149.1

DISABLING THE TEST ACCESS PORT

It is possible to use this device without utilizing the TAP. To

disable the TAP controller without interfering with normal

operation of the device, TCK must be tied to V

to preclude

input will produce a response identical to the application of a

logic one, and may be left unconnected. But they may also

BOUNDARY SCAN REGISTER

TEST ACCESS PORT PINS

The boundary scan register is identical in length to the

number of active input and I/O connections on the RAM (not

counting the TAP pins). This also includes a number of place

holder locations (always set to a logic one) reserved for den-

sity upgrade address pins. There are a total of 70 bits in the

case of the x36 device and 51 bits in the case of the x18 de-

vice. The boundary scan register, under the control of the

TAP controller, is loaded with the contents of the RAM I/O

ring when the controller is in capture–DR state and then is

placed between the TDI and TDO pins when the controller is

moved to shift–DR state. Several TAP instructions can be

used to activate the boundary scan register.

The Bump/Bit Scan Order tables describe which device

bump connects to each boundary scan register location. The

first column defines the bit’s position in the boundary scan

register. The shift register bit nearest TDO (i.e., first to be

shifted out) is defined as bit 1. The second column is the

name of the input or I/O at the bump and the third column is

the bump number.

TCK — TEST CLOCK (INPUT)

Clocks all TAP events. All inputs are captured on the rising

edge of TCK and all outputs propagate from the falling edge

of TCK.

TMS — TEST MODE SELECT (INPUT)

The TMS input is sampled on the rising edge of TCK. This

is the command input for the TAP controller state machine.

An undriven TMS input will produce the same result as a log-

ic one input level.

TDI — TEST DATA IN (INPUT)

The TDI input is sampled on the rising edge of TCK. This is

the input side of the serial registers placed between TDI and

TDO. The register placed between TDI and TDO is deter-

mined by the state of the TAP controller state machine and

the instruction that is currently loaded in the TAP instruction

register (see Figure 6). An undriven TDI pin will produce the

same result as a logic one input level.

IDENTIFICATION (ID) REGISTER

TDO — TEST DATA OUT (OUTPUT)

The ID register is a 32–bit register that is loaded with a de-

vice and vendor specific 32–bit code when the controller is

put in capture–DR state with the IDCODE command loaded

in the instruction register. The code is loaded from a 32–bit

on–chip ROM. It describes various attributes of the RAM as

indicated below. The register is then placed between the TDI

and TDO pins when the controller is moved into shift–DR

state. Bit 0 in the register is the LSB and the first to reach

TDO when shifting begins.

Output that is active depending on the state of the TAP

state machine (see Figure 6). Output changes in response to

the falling edge of TCK. This is the output side of the serial

registers placed between TDI and TDO.

TRST — TAP RESET

This device does not have a TRST pin. TRST is optional in

IEEE 1149.1. The test–logic reset state is entered while TMS

is held high for five rising edges of TCK. Power on reset cir-

cuitry is included internally. This type of reset does not affect

the operation of the system logic. The reset affects test logic

only.

paused for any other TAP operation except capturing the I/O

ring contents into the boundary scan register.

There are two classes of instructions defined in IEEE Stan-

dard 1149.1–1990, the standard (public) instructions and de-

vice specific (private) instructions. Some public instructions

are mandatory for IEEE 1149.1 compliance. Optional public

instructions must be implemented in prescribed ways.

Although the TAP controller in this device follows the IEEE

1149.1 conventions, it is not IEEE 1194.1 compliant because

some of the mandatory instructions are not fully imple-

mented. The TAP on this device may be used to monitor all

input and I/O pads, but cannot be used to load address, data,

or control signals into the RAM or to preload the I/O buffers.

In other words, the device will not perform IEEE 1149.1

EXTEST, INTEST, or the preload portion of the SAMPLE/

PRELOAD command.

When the TAP controller is placed in capture–IR state, the

two least significant bits of the instruction register are loaded

with 01. When the controller is moved to the shift–IR state,

the instruction register is placed between TDI and TDO. In

this state, the desired instruction is serially loaded through

the TDI input (while the previous contents are shifted out at

TDO). For all instructions, the TAP executes newly loaded

instructions only when the controller is moved to update–IR

state. The TAP instruction sets for this device are listed in the

following tables.

Moving the controller to shift–DR state then places the

boundary scan register between the TDI and TDO pins.

Because the PRELOAD portion of the command is not im-

plemented in this device, moving the controller to the

update–DR state with the SAMPLE/PRELOAD instruction

loaded in the instruction register has the same effect as the

pause–DR command. This functionality is not IEEE 1149.1

compliant.

EXTEST

EXTEST is an IEEE 1149.1 mandatory public instruction. It

is to be executed whenever the instruction register, whatever

length it may be in the device, is loaded with all logic zeros.

EXTEST is not implemented in this device. Therefore, this

device is not IEEE 1149.1 compliant. Nevertheless, this RAM

TAP does respond to an all zeros instruction, as follows. With

the EXTEST (000) instruction loaded in the instruction

register, the RAM responds just as it does in response to the

SAMPLE/PRELOAD instruction described above, except the

RAM outputs are forced to High–Z any time the instruction is

loaded.

IDCODE

The IDCODE instruction causes the ID ROM to be loaded

into the ID register when the controller is in capture–DR

mode and places the ID register between the TDI and TDO

pins in shift–DR mode. The IDCODE instruction is the default

instruction loaded in at power up and any time the controller

is placed in the test–logic–reset state.

STANDARD (PUBLIC) INSTRUCTIONS

BYPASS

The BYPASS instruction is loaded in the instruction regis-

ter when the bypass register is placed between TDI and

TDO. This occurs when the TAP controller is moved to the

shift–DR state. This allows the board level scan path to be

shortened to facilitate testing of other devices in the scan

path.

DEVICE SPECIFIC (PUBLIC) INSTRUCTION

SAMPLE–Z

SAMPLE/PRELOAD

If the SAMPLE–Z instruction is loaded in the instruction

register, all RAM outputs are forced to an inactive drive state

(High–Z) and the boundary scan register is connected be-

tween TDI and TDO when the TAP controller is moved to the

shift–DR state.

SAMPLE/PRELOAD is an IEEE 1149.1 mandatory public

instruction. When the SAMPLE/PRELOAD instruction is

loaded in the instruction register, moving the TAP controller

into the capture–DR state loads the data in the RAM’s input

and I/O buffers into the boundary scan register. Because the

RAM clock(s) are independent from the TAP clock (TCK) it is

possible for the TAP to attempt to capture the I/O ring con-

tents while the input buffers are in transition (i.e., in a metast-

able state). Although allowing the TAP to sample metastable

inputs will not harm the device, repeatable results cannot be
