1M Late Write HSTL

The MCM69R536/618 is a 1M–bit synchronous late write fast static RAM

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

Telecom, and other high speed memory applications. The MCM69R618

(organized as 64K words by 18 bits) and the MCM69R536 (organized as 32K

words by 36 bits wide) 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 driven on the rising edge of CK.

ZP PACKAGE

PBGA

CASE 999–02

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)

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 CMOS 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 mini-

mum or a maximum limit for each parameter. Input

requirementsare specified from the external system

point of view. Thus, address setup time is shown as

a minimum since the system must supply at least

that much time. On the other hand, responses from

the memory are specified from the device point of

view. Thus, the access time is shown as a maximum

since the device never provides data later than that

time.

be deselected as in a normal write cycle.

FUNCTIONAL OPERATION

READ AND WRITE OPERATIONS

LATE WRITE

All control signals except G are registered on the rising

edge of the CK clock. These signals must meet the setup

and hold times shown in the AC Characteristics table. On the

rising edge of the following clock, read data is clocked into

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 assure coherent

operation. This occurs in all cases, whether there is a byte

write or a full word is written.

the output register and available at the outputs at t

. Dur-

KHQV

ing this same cycle a new read address can be applied to the

address pins.

A deselect cycle (dead cycle) must occur prior to a write

cycle. Read cycles may follow write cycles immediately.

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

high on SS at the rising edge of the CK clock has its effect on

the output drivers after the next rising edge of the CK clock.

SW low deselects the output drivers immediately (as regis-

tered by CK). Output drive is also controlled directly by out-

put enable, G. No clock edges are required to generate

output disable with G. G asynchronously enables the output

drivers.

PROGRAMMABLE IMPEDANCE OPERATION

The designer can program the RAMs output buffer imped-

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 CK clock. Note that

if the CK 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

update method.

WRITE AND BYTE WRITE FUNCTIONS

The impedance update is not related to any particular type

of cycle because the impedance is updated continuously and

is based on the CK clock. Updates occur regardless of

whether the the device is performing a read, write, or a de-

select cycle and does not depend on the state of G.

At power up, the output impedance defaults to approx-

imately 50 Ω. 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.

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

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

parameters 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,

SS

The output buffers can also be programmed in a minimum

activated via a low on SW, and the rising edge of the CK

clock, write the entire RAM I/O width. This way the designer

is spared having to drive multiple write input buffer loads.

Byte writes are performed using the byte write enable in-

puts in conjunction with the SW. It is important to note that

writing any one byte will inhibit a read of all bytes at the cur-

rent address. The RAM can not simultaneously read one

byte and write another at the same address. A write cycle ini-

tiated with none of the byte write enable inputs active is nei-

impedance configuration by connecting ZQ to V

.

POWER UP AND INITIALIZATION

Once supplies have reached specification levels, a mini-

mum dwell of 1.0 ms with CK clock inputs cycling is required

before beginning normal operations. At power up the output

impedance will be set at approximately 50 Ω as stated

above.

SERIAL BOUNDARY SCAN TEST ACCESS PORT OPERATION

OVERVIEW

Standard 1149.1 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 Standard 1149.1–1990 (commonly referred to as

JTAG), but does not implement all of the functions required

for IEEE1149.1 compliance. Certain functions have been

modified or eliminated because their implementation places

extra delays in the RAMs critical speed path. Nevertheless,

the RAM supports the standard TAP controller architecture.

The TAP controller is the state machine that controls the

TAPs operation and can be expected to function in a manner

that does not conflict with the operation of devices with IEEE

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

mid–level inputs. TDI and TMS are designed so an undriven

input will produce a response identical to the application of a

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 1) reserved for density

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 device.

The boundary scan register, under the control of the TAP

controller, is loaded with the contents of the RAMs 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.

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

logic 1 input level.

TDI — TEST DATA IN (INPUT)

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.

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 (refer to Figure 6). An undriven TDI pin will produce

the same result as a logic 1 input level.

IDENTIFICATION (ID) REGISTER

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

device 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.

TDO — TEST DATA OUT (OUTPUT)

Output that is active depending on the state of the TAP

state machine (refer to Figure 6). Output changes in re-

sponse 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 re-

set circuitry is included internally. This type of reset does not

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

logic only.

OVERVIEW

data capture setup plus hold time (t

plus t ). The RAMs

CS

CH

clock inputs need not be 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 the IEEE

Standard 1149.1–1990; the standard (public) instructions,

and device specific (private) instructions. Some public

instructions, are mandatory for IEEE 1149.1 compliance. Op-

tional public instructions must be implemented in prescribed

ways.

Although the TAP controller in this device follows the IEEE

1149.1 conventions, it is not 1149.1 compliant because some

of the mandatory instructions are not fully implemented. The

TAP on this device may be used to monitor all input and I/O

pads, but can not 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 Standard 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

implemented 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 Standard

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 0s.

EXTEST is not implemented in this device. Therefore this

device is not IEEE 1149.1 compliant. Nevertheless, this

RAMs TAP does respond to an all 0s 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

DQ pins 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.

THE DEVICE SPECIFIC (PUBLIC) INSTRUCTION

SAMPLE–Z

SAMPLE/PRELOAD

If the SAMPLE–Z instruction is loaded in the instruction

register, all DQ pins 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 a Standard 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

RAMs 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 contents while the input buffers are in transition

(i.e., in a metastable state). Although allowing the TAP to

sample metastable inputs will not harm the device,
