with programmable polarity.
CAS
Output
Tri-Stated
Column Address Strobe— When the DSP is the bus master, CAS is an active-low
output used by DRAM to strobe the column address. Otherwise, if the bus mastership
enable (BME) bit in the DRAM control register is cleared, the signal is tri-stated.
RD
Output
Tri-Stated
Read Enable—When the DSP is the bus master, RD is an active-low output that is
asserted to read external memory on the data bus (D0-D23). Otherwise, RD is tri-stated.
WR
Output
Tri-Stated
Write Enable—When the DSP is the bus master, WR is an active-low output that is
asserted to write external memory on the data bus (D0-D23). Otherwise, WR is tri-stated.
TA
Input
Signal Description
Ignored Input Transfer Acknowledge—If the DSP is the bus master and there is no external bus
activity, or the DSP is not the bus master, the TA input is ignored. The TA input is a data
transfer acknowledge (DTACK) function that can extend an external bus cycle
indefinitely. Any number of wait states (1, 2. . .infinity) may be added to the wait states
inserted by the BCR by keeping TA deasserted. In typical operation, TA is deasserted
at the start of a bus cycle, is asserted to enable completion of the bus cycle, and is
deasserted before the next bus cycle. The current bus cycle completes one clock
period after TA is asserted synchronous to the internal system clock. The number of
wait states is determined by the TA input or by the bus control register (BCR),
whichever is longer. The BCR can be used to set the minimum number of wait states
in external bus cycles.
In order to use the TA functionality, the BCR must be programmed to at least one wait
state. A zero wait state access cannot be extended by TA deassertion, otherwise
improper operation may result. TA can operate synchronously or asynchronously,
depending on the setting of the TAS bit in the operating mode register (OMR).
TA functionality may not be used while performing DRAM type accesses, otherwise
improper operation may result.

BR
Output
Output
Bus Request—BR is an active-low output, never tri-stated. BR is asserted when the
(deasserted) DSP requests bus mastership. BR is deasserted when the DSP no longer needs the
bus. BR may be asserted or deasserted independent of whether the DSP56367 is a
bus master or a bus slave. Bus “parking” allows BR to be deasserted even though the
DSP56367 is the bus master. (See the description of bus “parking” in the BB signal
description.) The bus request hold (BRH) bit in the BCR allows BR to be asserted under
software control even though the DSP does not need the bus. BR is typically sent to an
external bus arbitrator that controls the priority, parking, and tenure of each master on
the same external bus. BR is only affected by DSP requests for the external bus, never
for the internal bus. During hardware reset, BR is deasserted and the arbitration is reset
to the bus slave state.
BG
Input
Ignored Input Bus Grant—BG is an active-low input. BG is asserted by an external bus arbitration
circuit when the DSP56367 becomes the next bus master. When BG is asserted, the
DSP56367 must wait until BB is deasserted before taking bus mastership. When BG is
deasserted, bus mastership is typically given up at the end of the current bus cycle.
This may occur in the middle of an instruction that requires more than one external bus
cycle for execution.
For proper BG operation, the asynchronous bus arbitration enable bit (ABE) in the
OMR register must be set.
BB
Input/
Output
Input
Bus Busy—BB is a bidirectional active-low input/output. BB indicates that the bus is
active. Only after BB is deasserted can the pending bus master become the bus master
(and then assert the signal again). The bus master may keep BB asserted after ceasing
bus activity regardless of whether BR is asserted or deasserted. This is called “bus
parking” and allows the current bus master to reuse the bus without rearbitration until
another device requires the bus. The deassertion of BB is done by an “active pull-up”
method (i.e., BB is driven high and then released and held high by an external pull-up
resistor).
For proper BB operation, the asynchronous bus arbitration enable bit (ABE) in the OMR
register must be set.
BB requires an external pull-up resistor.
2.9
Interrupt and Mode Control
The interrupt and mode control signals select the chip’s operating mode as it comes out of hardware reset.
After RESET is deasserted, these inputs are hardware interrupt request lines.

MODA/IRQA
Input
Input
Signal Description
Mode Select A/External Interrupt Request A—MODA/IRQA is an active-low
Schmitt-trigger input, internally synchronized to the DSP clock. MODA/IRQA selects
the initial chip operating mode during hardware reset and becomes a level-sensitive or
negative-edge-triggered, maskable interrupt request input during normal instruction
processing. MODA, MODB, MODC, and MODD select one of 16 initial chip operating
modes, latched into the OMR when the RESET signal is deasserted. If the processor
is in the stop standby state and the MODA/IRQA pin is pulled to GND, the processor
will exit the stop state.
This input is 3.3V tolerant.
MODB/IRQB
Input
Input
Mode Select B/External Interrupt Request B—MODB/IRQB is an active-low
Schmitt-trigger input, internally synchronized to the DSP clock. MODB/IRQB selects
the initial chip operating mode during hardware reset and becomes a level-sensitive or
negative-edge-triggered, maskable interrupt request input during normal instruction
processing. MODA, MODB, MODC, and MODD select one of 16 initial chip operating
modes, latched into OMR when the RESET signal is deasserted.
This input is 3.3V tolerant.
MODC/IRQC
Input
Input
Mode Select C/External Interrupt Request C—MODC/IRQC is an active-low
Schmitt-trigger input, internally synchronized to the DSP clock. MODC/IRQC selects
the initial chip operating mode during hardware reset and becomes a level-sensitive or
negative-edge-triggered, maskable interrupt request input during normal instruction
processing. MODA, MODB, MODC, and MODD select one of 16 initial chip operating

This input is 3.3V tolerant.
MODD/IRQD
Input
Input
Mode Select D/External Interrupt Request D—MODD/IRQD is an active-low
Schmitt-trigger input, internally synchronized to the DSP clock. MODD/IRQD selects
the initial chip operating mode during hardware reset and becomes a level-sensitive or
negative-edge-triggered, maskable interrupt request input during normal instruction
processing. MODA, MODB, MODC, and MODD select one of 16 initial chip operating
modes, latched into OMR when the RESET signal is deasserted.
This input is 3.3V tolerant.
RESET
Input
Input
Reset—RESET is an active-low, Schmitt-trigger input. When asserted, the chip is
placed in the Reset state and the internal phase generator is reset. The Schmitt-trigger
input allows a slowly rising input (such as a capacitor charging) to reset the chip reliably.
When the RESET signal is deasserted, the initial chip operating mode is latched from
the MODA, MODB, MODC, and MODD inputs. The RESET signal must be asserted
during power up. A stable EXTAL signal must be supplied while RESET is being
asserted.
This input is 3.3V tolerant.

Signal Description
SPI Serial Clock—The SCK signal is an output when the SPI is configured as a
master and a Schmitt-trigger input when the SPI is configured as a slave. When the
SPI is configured as a master, the SCK signal is derived from the internal SHI clock
generator. When the SPI is configured as a slave, the SCK signal is an input, and
the clock signal from the external master synchronizes the data transfer. The SCK
signal is ignored by the SPI if it is defined as a slave and the slave select (SS) signal
is not asserted. In both the master and slave SPI devices, data is shifted on one
edge of the SCK signal and is sampled on the opposite edge where data is stable.
Edge polarity is determined by the SPI transfer protocol.
I2C Serial Clock—SCL carries the clock for I2C bus transactions in the I2C mode.
SCL is a Schmitt-trigger input when configured as a slave and an open-drain output
when configured as a master. SCL should be connected to VCC through a pull-up
resistor.
This signal is tri-stated during hardware, software, and individual reset. Thus, there
is no need for an external pull-up in this state.
This input is 3.3V tolerant.
MISO

Tri-Stated
SPI Master-In-Slave-Out—When the SPI is configured as a master, MISO is the
master data input line. The MISO signal is used in conjunction with the MOSI signal
for transmitting and receiving serial data. This signal is a Schmitt-trigger input when
configured for the SPI Master mode, an output when configured for the SPI Slave
mode, and tri-stated if configured for the SPI Slave mode when SS is deasserted.
An external pull-up resistor is not required for SPI operation.
I2C Data and Acknowledge—In I2C mode, SDA is a Schmitt-trigger input when
receiving and an open-drain output when transmitting. SDA should be connected to
VCC through a pull-up resistor. SDA carries the data for I2C transactions. The data
in SDA must be stable during the high period of SCL. The data in SDA is only
allowed to change when SCL is low. When the bus is free, SDA is high. The SDA
line is only allowed to change during the time SCL is high in the case of start and
stop events. A high-to-low transition of the SDA line while SCL is high is a unique
situation, and is defined as the start event. A low-to-high transition of SDA while
SCL is high is a unique situation defined as the stop event.
This signal is tri-stated during hardware, software, and individual reset. Thus, there
is no need for an external pull-up in this state.
This input is 3.3V tolerant.

signal for transmitting and receiving serial data. MOSI is the slave data input line
when the SPI is configured as a slave. This signal is a Schmitt-trigger input when
configured for the SPI Slave mode.
I2C Slave Address 0—This signal uses a Schmitt-trigger input when configured for
the I2C mode. When configured for I2C slave mode, the HA0 signal is used to form
the slave device address. HA0 is ignored when configured for the I2C master mode.
This signal is tri-stated during hardware, software, and individual reset. Thus, there
is no need for an external pull-up in this state.
This input is 3.3V tolerant.
SS
Input
HA2
Input
Tri-Stated
SPI Slave Select—This signal is an active low Schmitt-trigger input when
configured for the SPI mode. When configured for the SPI Slave mode, this signal
is used to enable the SPI slave for transfer. When configured for the SPI master
mode, this signal should be kept deasserted (pulled high). If it is asserted while
configured as SPI master, a bus error condition is flagged. If SS is deasserted, the
SHI ignores SCK clocks and keeps the MISO output signal in the high-impedance
state.
I2C Slave Address 2—This signal uses a Schmitt-trigger input when configured for
the I2C mode. When configured for the I2C Slave mode, the HA2 signal is used to
form the slave device address. HA2 is ignored in the I2C master mode.
This signal is tri-stated during hardware, software, and individual reset. Thus, there
is no need for an external pull-up in this state.
This input is 3.3V tolerant.
HREQ
Input or
Output
Tri-Stated
Host Request—This signal is an active low Schmitt-trigger input when configured
for the master mode but an active low output when configured for the slave mode.
When configured for the slave mode, HREQ is asserted to indicate that the SHI is
ready for the next data word transfer and deasserted at the first clock pulse of the
new data word transfer. When configured for the master mode, HREQ is an input.
When asserted by the external slave device, it will trigger the start of the data word
transfer by the master. After finishing the data word transfer, the master will await
the next assertion of HREQ to proceed to the next transfer.
This signal is tri-stated during hardware, software, personal reset, or when the
HREQ1–HREQ0 bits in the HCSR are cleared. There is no need for external pull-up
in this state.
This input is 3.3V tolerant.

Signal Description
Timer 0 Schmitt-Trigger Input/Output—When timer 0 functions as an
external event counter or in measurement mode, TIO0 is used as input. When
timer 0 functions in watchdog, timer, or pulse modulation mode, TIO0 is used
as output.
The default mode after reset is GPIO input. This can be changed to output or
configured as a timer input/output through the timer 0 control/status register
(TCSR0). If TIO0 is not being used, it is recommended to either define it as
GPIO output immediately at the beginning of operation or leave it defined as
GPIO input but connected to Vcc through a pull-up resistor in order to ensure
a stable logic level at this input.
This input is 3.3 V tolerant.

Specifications
Introduction
The DSP56367 is a high density CMOS device with Transistor-Transistor Logic (TTL) compatible inputs
and outputs.
NOTE
This document contains information on a new product. Specifications and
information herein are subject to change without notice.
Finalized specifications may be published after further characterization and device qualifications are
completed.
3.2
Maximum Ratings
CAUTION
This device contains circuitry protecting against damage due to high static
voltage or electrical fields. However, normal precautions should be taken to
avoid exceeding maximum voltage ratings. Reliability of operation is
enhanced if unused inputs are pulled to an appropriate logic voltage level
(for example, either GND or VCC). The suggested value for a pull-up or
pull-down resistor is 10 kΩ.
NOTE
In the calculation of timing requirements, adding a maximum value of one
specification to a minimum value of another specification does not yield a
reasonable sum. A maximum specification is calculated using a worst case
variation of process parameter values in one direction. The minimum
specification is calculated using the worst case for the same parameters in
the opposite direction. Therefore, a “maximum” value for a specification
will never occur in the same device that has a “minimum” value for another
specification; adding a maximum to a minimum represents a condition that
can never exist.

AC Electrical Characteristics
3
This characteristic does not apply to PCAP.
The Appendix A, "Power Consumption Benchmark" section provides a formula to compute the estimated current
requirements in Normal mode. In order to obtain these results, all inputs must be terminated (i.e., not allowed to float).
Measurements are based on synthetic intensive DSP benchmarks. The power consumption numbers in this specification are
90% of the measured results of this benchmark. This reflects typical DSP applications. Typical internal supply current is
measured with VCCQL = 1.8V, VCC(other) = 3.3V at TJ = 25°C. Maximum internal supply current is measured with VCCQL = 1.89V,
VCC(other) = 3.46V at TJ = 95°C.
5
In order to obtain these results, all inputs, which are not disconnected at Stop mode, must be terminated (i.e., not allowed to
float).

AC Electrical Characteristics
The timing waveforms shown in the AC electrical characteristics section are tested with a VIL maximum
of 0.4 V and a VIH minimum of 2.4 V for all pins except EXTAL. AC timing specifications, which are
referenced to a device input signal, are measured in production with respect to the 50% point of the
respective input signal’s transition. DSP56367 output levels are measured with the production test machine
VOL and VOH reference levels set at 0.4 V and 2.4 V, respectively.
NOTE
Although the minimum value for the frequency of EXTAL is 0 MHz, the
device AC test conditions are 15 MHz and rated speed.

The indicated duty cycle is for the specified maximum frequency for which a part is rated. The minimum clock high or low time
required for correct operation, however, remains the same at lower operating frequencies; therefore, when a lower clock
frequency is used, the signal symmetry may vary from the specified duty cycle as long as the minimum high time and low time
requirements are met.

VCCQH = 3.3 V ± 5%; VCC= 1.8V ± 5%; TJ = –40°C to + 95°C, CL = 50 pF
Periodically sampled and not 100% tested.
RESET duration is measured during the time in which RESET is asserted, VCC is valid, and the EXTAL input is active and
valid. When the VCC is valid, but the other “required RESET duration” conditions (as specified above) have not been yet met,
the device circuitry will not be in an initialized state that can result in significant power consumption and heat-up. Designs
should minimize this state to the shortest possible duration.
If PLL does not lose lock.
When using fast interrupts and IRQA, IRQB, IRQC, and IRQD are defined as level-sensitive, timings 19 through 21 apply to
prevent multiple interrupt service. To avoid these timing restrictions, the deasserted Edge-triggered mode is recommended
when using fast interrupts. Long interrupts are recommended when using Level-sensitive mode.
WS = number of wait states (measured in clock cycles, number of TC).
Use expression to compute maximum value.
This timing depends on several settings:
For PLL disable, using external clock (PCTL Bit 16 = 1), no stabilization delay is required and recovery time will be defined
by the PCTL Bit 17 and OMR Bit 6 settings.
For PLL enable, if PCTL Bit 17 is 0, the PLL is shutdown during Stop. Recovering from Stop requires the PLL to get locked.
The PLL lock procedure duration, PLL Lock Cycles (PLC), may be in the range of 0 to 1000 cycles. This procedure occurs
in parallel with the stop delay counter, and stop recovery will end when the last of these two events occurs: the stop delay
counter completes count or PLL lock procedure completion.
PLC value for PLL disable is 0.
The maximum value for ETC is 4096 (maximum MF) divided by the desired internal frequency (i.e., for 150 MHz it is
4096/150 MHz = 27.3 µs). During the stabilization period, TC, TH, and TL will not be constant, and their width may vary, so
timing may vary as well.

WS is the number of wait states specified in the BCR. The value is given for the minimum for a given category. (For example,
for a category of [2 ≤ WS ≤ 7] timing is specified for 2 wait states.) Two wait states is the minimum otherwise.
2 Timings 100, 107 are guaranteed by design, not tested.
3 In the case of TA negation: timing 118 is relative to the deassertion edge of RD or WR were TA to remain active.

DRAM Timing
The selection guides provided in Figure 3-11 and Figure 3-14 should be used for primary selection only.
Final selection should be based on the timing provided in the following tables. As an example, the selection
guide suggests that 4 wait states must be used for 100 MHz operation when using Page Mode DRAM.
However, by using the information in the appropriate table, a designer may choose to evaluate whether
fewer wait states might be used by determining which timing prevents operation at 100 MHz, running the
chip at a slightly lower frequency (e.g., 95 MHz), using faster DRAM (if it becomes available), and control
factors such as capacitive and resistive load to improve overall system performance.
Note: This figure should be use for primary selection. For
exact and detailed timings see the following tables.

The number of wait states for Page mode access is specified in the DCR.
The refresh period is specified in the DCR.
The asynchronous delays specified in the expressions are valid for DSP56367.
All the timings are calculated for the worst case. Some of the timings are better for specific cases (e.g., tPC equals 4 × TC for
read-after-read or write-after-write sequences).
BRW[1:0] (DRAM control register bits) defines the number of wait states that should be inserted in each DRAM out-of
page-access.
RD deassertion will always occur after CAS deassertion; therefore, the restricted timing is tOFF and not tGZ.

The number of wait states for Page mode access is specified in the DCR.
The refresh period is specified in the DCR.
The asynchronous delays specified in the expressions are valid for DSP56367.
All the timings are calculated for the worst case. Some of the timings are better for specific cases (for example, tPC equals
3 × TC for read-after-read or write-after-write sequences). An expressions is used to calculate the maximum or minimum
value listed, as appropriate.
BRW[1–0] (DRAM control register bits) defines the number of wait states that should be inserted in each DRAM out-of-page
access.
RD deassertion always occurs after CAS deassertion; therefore, the restricted timing is tOFF and not tGZ.

Bit 13 in the OMR register must be set to enter Asynchronous Arbitration mode.
If Asynchronous Arbitration mode is active, none of the timings in Table 3-14 is required.
3 In order to guarantee timings 250, and 251, it is recommended to assert BG inputs to different 56300 devices (on the same
bus) in a non overlap manner as shown in Figure 3-18.

Background explanation for Asynchronous Bus Arbitration:
The asynchronous bus arbitration is enabled by internal synchronization circuits on BG and BB inputs.
These synchronization circuits add delay from the external signal until it is exposed to internal logic. As a
result of this delay, a 56300 part may assume mastership and assert BB for some time after BG is negated.
This is the reason for timing 250.
Once BB is asserted, there is a synchronization delay from BB assertion to the time this assertion is
exposed to other 56300 components which are potential masters on the same bus. If BG input is asserted
before that time, a situation of BG asserted, and BB negated, may cause another 56300 component to
assume mastership at the same time. Therefore some non-overlap period between one BG input active to
another BG input active is required. Timing 251 ensures that such a situation is avoided.

See Host Port Usage Considerations in the DSP56367 User’s Manual.
In the timing diagrams below, the controls pins are drawn as active low. The pin polarity is programmable.
VCC = 1.8 V ± 5%; TJ = –40°C to +95°C, CL = 50 pF
The read data strobe is HRD in the dual data strobe mode and HDS in the single data strobe mode.
The “last data register” is the register at address $7, which is the last location to be read or written in data transfers.
This timing is applicable only if a read from the “last data register” is followed by a read from the RXL, RXM, or RXH registers
without first polling RXDF or HREQ bits, or waiting for the assertion of the HOREQ signal.
This timing is applicable only if two consecutive reads from one of these registers are executed.
The write data strobe is HWR in the dual data strobe mode and HDS in the single data strobe mode.

The data strobe is host read (HRD) or host write (HWR) in the dual data strobe mode and host data strobe (HDS) in the single
data strobe mode.
10
The host request is HOREQ in the single host request mode and HRRQ and HTRQ in the double host request mode.
11
In this calculation, the host request signal is pulled up by a 4.7 kΩ resistor in the open-drain mode.

3.13.1
Programming the Serial Clock
The programmed serial clock cycle, T I CCP, is specified by the value of the HDM[7:0] and HRS bits of the
HCKR (SHI clock control register).
2
The expression for T I CCP is
2
T
where
= [ T C × 2 × ( H DM [ 7 :0 ] + 1 ) × ( 7 × ( 1 – HRS ) + 1 ) ]
2
I CCP
HRS is the prescaler rate select bit. When HRS is cleared, the fixed divide-by-eight prescaler is
operational. When HRS is set, the prescaler is bypassed.
HDM[7:0] are the divider modulus select bits. A divide ratio from 1 to 256
(HDM[7:0] = $00 to $FF) may be selected.
In I2C mode, the user may select a value for the programmed serial clock cycle from
6 × TC ( if HDM [ 7 :0 ] = $02 and HRS = 1 )
to
4096 × T C ( if HDM [ 7 :0 ] = $FF and HRS = 0 )
The programmed serial clock cycle (TI CCP ), SCL rise time (TR), and the filters selected should be chosen
in order to achieve the desired SCL serial clock cycle (TSCL), as shown in Table 3-18.
2
Table 3-18 SCL Serial Clock Cycle (TSCL) Generated as Master
Filters bypassed
TI2CCP + 2.5 × TC + 45ns + TR
Narrow filters enabled
TI2CCP + 2.5 × TC + 135ns + TR
Wide filters enabled
TI2CCP + 2.5 × TC + 223ns + TR
EXAMPLE:
For DSP clock frequency of 100 MHz (i.e. TC = 10ns), operating in a standard mode I2C environment
(FSCL = 100 kHz (i.e. TSCL = 10µs), TR = 1000ns), with wide filters enabled:
T
2
I CCP
= 10µs – 2.5 × 10ns – 223ns – 1000ns = 8752ns
Choosing HRS = 0 gives
HDM [ 7 :0 ] = ( 8752ns ) ⁄ ( 2 × 10ns × 8 ) – 1 = 53.7
Thus the HDM[7:0] value should be programmed to $36 (=54).
The resulting TI CCP will be:
2
T
I CCP
= [ T C × 2 × ( H DM [ 7 :0 ] + 1 ) × ( 7 × ( 1 – 0 ) + 1 ) ]
T
= [ 10ns × 2 × ( 54 + 1 ) × ( 7 × ( 1 – 0 ) + 1 ) ]
2
2
I CCP
T
2
I CCP
= [ 10 ns × 2 × 54 × 8 ] = 8640ns

The timing values calculated are based on simulation data at 150MHz. Tester restrictions limit ESAI testing to lower clock
frequencies.
ESAI_1 specs match those of ESAI_0.
VCC = 1.8 V ± 5%; TJ = –40°C to +95°C, CL = 50 pF
i ck = internal clock
x ck = external clock
i ck a = internal clock, asynchronous mode (asynchronous implies that TXC and RXC are two different clocks)
i ck s = internal clock, synchronous mode (synchronous implies that TXC and RXC are the same clock)
bl = bit length
wl = word length
wr = word length relative
TXC(SCKT pin) = transmit clock
RXC(SCKR pin) = receive clock
FST(FST pin) = transmit frame sync
FSR(FSR pin) = receive frame sync
HCKT(HCKT pin) = transmit high frequency clock
HCKR(HCKR pin) = receive high frequency clock
For the internal clock, the external clock cycle is defined by Icyc and the ESAI control register.

The word-relative frame sync signal waveform relative to the clock operates in the same manner as the bit-length frame sync
signal waveform, but spreads from one serial clock before first bit clock (same as bit length frame sync signal), until the one
before last bit clock of the first word in frame.

In order to assure proper operation of the DAX, the ACI frequency should be less than 1/2 of the DSP56367 internal
clock frequency. For example, if the DSP56367 is running at 150 MHz internally, the ACI frequency should be less
than 75 MHz.

Design Considerations
Thermal Design Considerations
An estimation of the chip junction temperature, TJ, in °C can be obtained from the following equation:
TJ = T A + ( P D × R θJA )
Where:
TA
= ambient temperature °C
RqJA = package junction-to-ambient thermal resistance °C/W
PD
= power dissipation in package W
Historically, thermal resistance has been expressed as the sum of a junction-to-case thermal resistance and
a case-to-ambient thermal resistance.
R θJA = R θJC + R θCA
Where:
RθJA = package junction-to-ambient thermal resistance °C/W
RθJC = package junction-to-case thermal resistance °C/W
RθCA = package case-to-ambient thermal resistance °C/W
RθJC is device-related and cannot be influenced by the user. The user controls the thermal environment to
change the case-to-ambient thermal resistance, RθCA. For example, the user can change the air flow around
the device, add a heat sink, change the mounting arrangement on the printed circuit board (PCB), or
otherwise change the thermal dissipation capability of the area surrounding the device on a PCB. This
model is most useful for ceramic packages with heat sinks; some 90% of the heat flow is dissipated through
the case to the heat sink and out to the ambient environment. For ceramic packages, in situations where
the heat flow is split between a path to the case and an alternate path through the PCB, analysis of the
device thermal performance may need the additional modeling capability of a system level thermal
simulation tool.
The thermal performance of plastic packages is more dependent on the temperature of the PCB to which
the package is mounted. Again, if the estimations obtained from RθJA do not satisfactorily answer whether
the thermal performance is adequate, a system level model may be appropriate.
A complicating factor is the existence of three common ways for determining the junction-to-case thermal
resistance in plastic packages.

Electrical Design Considerations
•
•
•
To minimize temperature variation across the surface, the thermal resistance is measured from the
junction to the outside surface of the package (case) closest to the chip mounting area when that
surface has a proper heat sink.
To define a value approximately equal to a junction-to-board thermal resistance, the thermal
resistance is measured from the junction to where the leads are attached to the case.
If the temperature of the package case (TT) is determined by a thermocouple, the thermal resistance
is computed using the value obtained by the equation: (TJ – TT)/PD.
As noted above, the junction-to-case thermal resistances quoted in this data sheet are determined using the
first definition. From a practical standpoint, that value is also suitable for determining the junction
temperature from a case thermocouple reading in forced convection environments. In natural convection,
using the junction-to-case thermal resistance to estimate junction temperature from a thermocouple
reading on the case of the package will estimate a junction temperature slightly hotter than actual
temperature. Hence, the new thermal metric, thermal characterization parameter or ΨJT, has been defined
to be (TJ – TT)/PD. This value gives a better estimate of the junction temperature in natural convection
when using the surface temperature of the package. Remember that surface temperature readings of
packages are subject to significant errors caused by inadequate attachment of the sensor to the surface and
to errors caused by heat loss to the sensor. The recommended technique is to attach a 40-gauge
thermocouple wire and bead to the top center of the package with thermally conductive epoxy.
5.2
Electrical Design Considerations
CAUTION
This device contains circuitry protecting against damage due to high static
voltage or electrical fields. However, normal precautions should be taken to
avoid exceeding maximum voltage ratings. Reliability of operation is
enhanced if unused inputs are tied to an appropriate logic voltage level (e.g.,
either GND or VCC). The suggested value for a pull-up or pull-down resistor
is 10 k ohm.
Use the following list of recommendations to assure correct DSP operation:
• Provide a low-impedance path from the board power supply to each VCC pin on the DSP and from
the board ground to each GND pin.
• Use at least six 0.01–0.1 µF bypass capacitors positioned as close as possible to the four sides of
the package to connect the VCC power source to GND.
• Ensure that capacitor leads and associated printed circuit traces that connect to the chip VCC and
GND pins are less than 1.2 cm (0.5 inch) per capacitor lead.
• Use at least a four-layer PCB with two inner layers for VCC and GND.
• Because the DSP output signals have fast rise and fall times, PCB trace lengths should be minimal.
This recommendation particularly applies to the address and data buses as well as the IRQA,
IRQB, IRQD, and TA pins. Maximum PCB trace lengths on the order of 15 cm (6 inches) are
recommended.

Power Consumption Considerations
•
•
•
•
•
•
Consider all device loads as well as parasitic capacitance due to PCB traces when calculating
capacitance. This is especially critical in systems with higher capacitive loads that could create
higher transient currents in the VCC and GND circuits.
All inputs must be terminated (i.e., not allowed to float) using CMOS levels, except for the three
pins with internal pull-up resistors (TMS, TDI, TCK).
Take special care to minimize noise levels on the VCCP and GNDP pins.
If multiple DSP56367 devices are on the same board, check for cross-talk or excessive spikes on
the supplies due to synchronous operation of the devices.
RESET must be asserted when the chip is powered up. A stable EXTAL signal must be supplied
before deassertion of RESET.
At power-up, ensure that the voltage difference between the 3.3 V tolerant pins and the chip VCC
never exceeds a TBD voltage.
5.3
Power Consumption Considerations
Power dissipation is a key issue in portable DSP applications. Some of the factors which affect current
consumption are described in this section. Most of the current consumed by CMOS devices is alternating
current (ac), which is charging and discharging the capacitances of the pins and internal nodes.
Current consumption is described by the following formula:
I = C×V×f
where:
C
V
f
= node/pin capacitance
= voltage swing
= frequency of node/pin toggle
Example 1. Power Consumption
For a Port A address pin loaded with 50 pF capacitance, operating at 3.3 V, and with a 100 MHz clock,
toggling at its maximum possible rate (50 MHz), the current consumption is
I = 50 × 10
– 12
6
× 3.3 × 50 × 10 = 8.25mA
The maximum internal current (ICCImax) value reflects the typical possible switching of the internal buses
on best-case operation conditions, which is not necessarily a real application case. The typical internal
current (ICCItyp) value reflects the average switching of the internal buses on typical operating conditions.
For applications that require very low current consumption, do the following:
• Set the EBD bit when not accessing external memory.
• Minimize external memory accesses and use internal memory accesses.
• Minimize the number of pins that are switching.
• Minimize the capacitive load on the pins.
• Connect the unused inputs to pull-up or pull-down resistors.
• Disable unused peripherals.

5-3
PLL Performance Issues
One way to evaluate power consumption is to use a current per MIPS measurement methodology to
minimize specific board effects (i.e., to compensate for measured board current not caused by the DSP).
A benchmark power consumption test algorithm is listed in Appendix A, "Power Consumption
Benchmark". Use the test algorithm, specific test current measurements, and the following equation to
derive the current per MIPS value.
I ⁄ MIPS = I ⁄ MHz = ( I typF2 – I typF1 ) ⁄ ( F2 – F1 )
where:
ItypF2 = current at F2
ItypF1 = current at F1
F2
= high frequency (any specified operating frequency)
F1
= low frequency (any specified operating frequency lower than F2)
NOTE
F1 should be significantly less than F2. For example, F2 could be 66 MHz
and F1 could be 33 MHz. The degree of difference between F1 and F2
determines the amount of precision with which the current rating can be
determined for an application.
5.4
PLL Performance Issues
The following explanations should be considered as general observations on expected PLL behavior.
There is no testing that verifies these exact numbers. These observations were measured on a limited
number of parts and were not verified over the entire temperature and voltage ranges.
5.4.1
Input (EXTAL) Jitter Requirements
The allowed jitter on the frequency of EXTAL is 0.5%. If the rate of change of the frequency of EXTAL
is slow (i.e., it does not jump between the minimum and maximum values in one cycle) or the frequency
of the jitter is fast (i.e., it does not stay at an extreme value for a long time), then the allowed jitter can be
2%. The phase and frequency jitter performance results are only valid if the input jitter is less than the
prescribed values.

Appendix A Power Consumption Benchmark
The following benchmark program permits evaluation of DSP power usage in a test situation. It enables
the PLL, disables the external clock, and uses repeated multiply-accumulate instructions with a set of
synthetic DSP application data to emulate intensive sustained DSP operation.
