Figure 1. DSP56311 Block Diagram
The Freescale DSP56311, a member of the DSP56300 DSP family, supports network applications with general filtering
operations. The Enhanced Filter Coprocessor (EFCOP) executes filter algorithms in parallel with core operations enhancing
signal quality with no impact on channel throughput or total channels supported. The result is increased overall performance.
Like the other DSP56300 family members, the DSP56311 uses a high-performance, single-clock-cycle-per- instruction engine
(DSP56000 code-compatible), a barrel shifter, 24-bit addressing, an instruction cache, and a direct memory access (DMA)
controller (see Figure 1). The DSP56311 performs at up to 150 million multiply-accumulates per second (MMACS), attaining
up to 300 MMACS when the EFCOP is in use. It operates with an internal 150 MHz clock with a 1.8 volt core and
independent 3.3 volt input/output (I/O) power.

Port A signals define the external memory interface port, including the external address bus, data bus, and control signals.
Port B signals are the HI08 port signals multiplexed with the GPIO signals.
Port C and D signals are the two ESSI port signals multiplexed with the GPIO signals.
Port E signals are the SCI port signals multiplexed with the GPIO signals.
There are 5 signal connections that are not used. These are designated as no connect (NC) in the package description (see
Chapter 3).
Note: The Clock Output (CLKOUT), BCLK, BCLK, CAS, and RAS[0–3] signals used by other DSP56300 family members
are supported by the DSP56311 at operating frequencies up to 100 MHz. Therefore, above 100 MHz, you must
enable bus arbitration by setting the Asynchronous Bus Arbitration Enable Bit (ABE) in the operating mode register.
When set, the ABE bit eliminates the required set-up and hold times for BB and BG with respect to CLKOUT. In
addition, DRAM access is not supported above 100 MHz.

The HI08 port supports a non-multiplexed or a multiplexed bus, single or double Data Strobe (DS), and single or
double Host Request (HR) configurations. Since each of these modes is configured independently, any combination
of these modes is possible. These HI08 signals can also be configured alternatively as GPIO signals (PB[0–15]).
Signals with dual designations (for example, HAS/HAS) have configurable polarity.
The ESSI0, ESSI1, and SCI signals are multiplexed with the Port C GPIO signals (PC[0–5]), Port D GPIO signals
(PD[0–5]), and Port E GPIO signals (PE[0–2]), respectively.
TIO[0–2] can be configured as GPIO signals.
CLKOUT, BCLK, BCLK, CAS, and RAS[0–3] are valid only for operating frequencies ≤100 MHz.

Signal Description
Chip-driven
Clock Output—Provides an output clock synchronized to the internal core
clock phase.
If the PLL is enabled and both the multiplication and division factors equal one,
then CLKOUT is also synchronized to EXTAL.
If the PLL is disabled, the CLKOUT frequency is half the frequency of EXTAL.
Note: At operating frequencies above 100 MHz, this signal produces a lowamplitude waveform that is not usable externally by other devices. Above 100
MHz, you can use the asynchronous bus arbitration option that is enabled by
the Asynchronous Bus Arbitration Enable (ABE) bit in the Operating Mode
Register. When set, the DSP enters the Asynchronous Arbitration mode,
which eliminates the BB and BG set-up and hold time requirements with
respect to CLKOUT.
PCAP
Input
Input
PLL Capacitor—An input connecting an off-chip capacitor to the PLL filter.
Connect one capacitor terminal to PCAP and the other terminal to VCCP.
If the PLL is not used, PCAP can be tied to VCC, GND, or left floating.
PINIT
Input
NMI
Input
Input
PLL Initial—During assertion of RESET, the value of PINIT is written into the
PLL enable (PEN) bit of the PLL control (PCTL) register, determining whether
the PLL is enabled or disabled.
Nonmaskable Interrupt—After RESET deassertion and during normal
instruction processing, this Schmitt-trigger input is the negative-edge-triggered
NMI request internally synchronized to CLKOUT.
1.5 External Memory Expansion Port (Port A)
Note: When the DSP56311 enters a low-power standby mode (stop or wait), it releases bus mastership and tristates the relevant Port A signals: A[0–17], D[0–23], AA[0–3], RD, WR, BB.

Signal Description
Address Attribute—When defined as AA, these signals can be used as chip selects
or additional address lines. The default use defines a priority scheme under which
only one AA signal can be asserted at a time. Setting the AA priority disable (APD) bit
(Bit 14) of the Operating Mode Register, the priority mechanism is disabled and the
lines can be used together as four external lines that can be decoded externally into
16 chip select signals.
Row Address Strobe—When defined as RAS, these signals can be used as RAS for
DRAM interface. These signals are tri-statable outputs with programmable polarity.
Note: DRAM access is not supported above 100 MHz.
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 (D[0–23]). Otherwise, RD is tristated.
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 (D[0–23]). Otherwise, the signals
are tri-stated.
TA
Input
Ignored Input
Transfer Acknowledge—If the DSP56311 is the bus master and there is no external
bus activity, or the DSP56311 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) can be added to the
wait states inserted by the bus control register (BCR) by keeping TA deasserted. In
typical operation, TA is deasserted at the start of a bus cycle, asserted to enable
completion of the bus cycle, and deasserted before the next bus cycle. The current
bus cycle completes one clock period after TA is deasserted. The number of wait
states is determined by the TA input or by the BCR, whichever is longer. The BCR
sets 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.
At operating frequencies ≤100 MHz, TA can operate synchronously (with respect to
CLKOUT) or asynchronously depending on the setting of the TAS bit in the Operating
Mode Register (OMR). If synchronous mode is selected, the user is responsible for
ensuring that TA transitions occur synchronous to CLKOUT to ensure correct
operation. Synchronous operation is not supported above 100 MHz and the
OMR[TAS] bit must be set to synchronize the TA signal with the internal clock.

Signal Description
Bus Request—Asserted when the DSP requests bus mastership. BR is deasserted
when the DSP no longer needs the bus. BR may be asserted or deasserted
independently of whether the DSP56311 is a bus master or a bus slave. Bus
“parking” allows BR to be deasserted even though the DSP56311 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 affected only 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.
Bus Grant—Asserted by an external bus arbitration circuit when the DSP56311
becomes the next bus master. When BG is asserted, the DSP56311 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.
The default operation of this bit requires a set-up and hold time as specified in
Chapter 2. An alternate mode can be invoked: set the asynchronous bus arbitration
enable (ABE) bit (Bit 13) in the Operating Mode Register. When this bit is set, BG and
BB are synchronized internally. This eliminates the respective set-up and hold time
requirements but adds a required delay between the deassertion of an initial BG input
and the assertion of a subsequent BG input.
BB
Input/ Output Ignored Input
Bus Busy—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. Called “bus parking,” this allows the current bus master
to reuse the bus without rearbitration until another device requires the bus. BB is
deasserted by an “active pull-up” method (that is, BB is driven high and then released
and held high by an external pull-up resistor).
The default operation of this signal requires a set-up and hold time as specified in
Chapter 2. An alternative mode can be invoked by setting the ABE bit (Bit 13) in the
Operating Mode Register. When this bit is set, BG and BB are synchronized
internally. See BG for additional information.
Note: BB requires an external pull-up resistor.
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 tristated.
Note: DRAM access is not supported above 100 MHz.
BCLK

Bus Clock
When the DSP is the bus master, BCLK is active when the ATE bit in the Operating
Mode Register is set. When BCLK is active and synchronized to CLKOUT by the
internal PLL, BCLK precedes CLKOUT by one-fourth of a clock cycle.
Note: At operating frequencies above 100 MHz, this signal produces a low-amplitude
waveform that is not usable externally by other devices.

When the DSP is the bus master, BCLK is the inverse of the BCLK signal. Otherwise,

Reset—Places the chip in the Reset state and resets the internal phase
generator. 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 after
powerup.

1.7 Host Interface (HI08)
The HI08 provides a fast, 8-bit, parallel data port that connects directly to the host bus. The HI08 supports a variety
of standard buses and connects directly to a number of industry-standard microcomputers, microprocessors, DSPs,
and DMA hardware.
1.7.1
Host Port Usage Considerations
Careful synchronization is required when the system reads multiple-bit registers that are written by another
asynchronous system. This is a common problem when two asynchronous systems are connected (as they are in the
Host port). The considerations for proper operation are discussed in Table 1-10.
Table 1-10.
Host Port Usage Considerations
Action
Description
Asynchronous read of receive byte
registers
When reading the receive byte registers, Receive register High (RXH), Receive register Middle
(RXM), or Receive register Low (RXL), the host interface programmer should use interrupts or poll
the Receive register Data Full (RXDF) flag that indicates data is available. This assures that the data
in the receive byte registers is valid.
Asynchronous write to transmit byte
registers
The host interface programmer should not write to the transmit byte registers, Transmit register High
(TXH), Transmit register Middle (TXM), or Transmit register Low (TXL), unless the Transmit register
Data Empty (TXDE) bit is set indicating that the transmit byte registers are empty. This guarantees
that the transmit byte registers transfer valid data to the Host Receive (HRX) register.
Asynchronous write to host vector
The host interface programmer must change the Host Vector (HV) register only when the Host
Command bit (HC) is clear. This practice guarantees that the DSP interrupt control logic receives a
stable vector.
1.7.2

enter Debug mode, and wait for commands to be entered from the debug
serial input line. This signal is asserted as an output for three clock cycles
when the chip enters Debug mode as a result of a debug request or as a result
of meeting a breakpoint condition. The DE has an internal pull-up resistor.
DE
Signal Description
This signal is not a standard part of the JTAG TAP controller. The signal
connects directly to the OnCE module to initiate debug mode directly or to
provide a direct external indication that the chip has entered Debug mode. All
other interface with the OnCE module must occur through the JTAG port.

2.1 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 is enhanced if
unused inputs are tied to an appropriate logic
voltage level (for example, either GND or VCC).
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 never
occurs 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.

the maximum rating may affect device reliability or cause permanent damage to the device.
Power-up sequence: During power-up, and throughout the DSP56311 operation, VCCQH voltage must always be higher or
equal to VCC voltage.

Refers to MODA/IRQA, MODB/IRQB, MODC/IRQC, and MODD/IRQD pins.
Section 4.3 provides a formula to compute the estimated current requirements in Normal mode. To obtain these results, all
inputs must be terminated (that is, not allowed to float). Measurements are based on synthetic intensive DSP benchmarks (see
Appendix A). The power consumption numbers in this specification are 90 percent of the measured results of this benchmark.
This reflects typical DSP applications. Typical internal supply current is measured with VCCQP = 3.3 V,
V CC = 1.8 V at TJ = 100°C.
To obtain these results, all inputs must be terminated (that is, not allowed to float). PLL and XTAL signals are disabled during
Stop state.
DC current in Stop mode is evaluated based on measurements. To obtain these results, all inputs not disconnected at Stop
mode must be terminated (that is, not allowed to float).
Periodically sampled and not 100 percent tested.
V CCQH = 3.3 V ± 0.3 V, VCC = 1.8 V ± 0.1 V; TJ = –40°C to +100 °C, CL = 50 pF
This characteristic does not apply to XTAL and PCAP.
Driving EXTAL to the low VIHX or the high VILX value may cause additional power consumption (DC current). To minimize
power consumption, the minimum VIHX should be no lower than
0.9 × VCCQH and the maximum VILX should be no higher than 0.1 × VCCQH .

2.4 AC Electrical Characteristics
The timing waveforms shown in the AC electrical characteristics section are tested with a VIL maximum of 0.3 V
and a VIH minimum of 2.4 V for all pins except EXTAL, which is tested using the input levels shown in Note 6 of
Table 2-2. AC timing specifications, which are referenced to a device input signal, are measured in production with
respect to the 50 percent point of the respective input signal’s transition. DSP56311 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 correction operation, however, remains the same at lower operating frequencies; therefore, when a lower clock

When fast interrupts are used 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 fast interrupts are used. Long interrupts are recommended for Level-sensitive mode.
This timing depends on several settings:
• For PLL disable, using internal oscillator (PLL Control Register (PCTL) Bit 16 = 0) and oscillator disabled during Stop (PCTL
Bit 17 = 0), a stabilization delay is required to assure that the oscillator is stable before programs are executed. Resetting the
Stop delay (Operating Mode Register Bit 6 = 0) provides the proper delay. While Operating Mode Register Bit 6 = 1 can be set,
it is not recommended, and these specifications do not guarantee timings for that case.
• For PLL disable, using internal oscillator (PCTL Bit 16 = 0) and oscillator enabled during Stop (PCTL Bit 17=1), no
stabilization delay is required and recovery is minimal (Operating Mode Register Bit 6 setting is ignored).
• For PLL disable, using external clock (PCTL Bit 16 = 1), no stabilization delay is required and recovery time is defined by the
PCTL Bit 17 and Operating Mode Register 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 ends 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 (that is, for 66 MHz it is 4096/66
MHz = 62 µs). During the stabilization period, TC, TH, and TL is not constant, and their width may vary, so timing may vary as
well.
Periodically sampled and not 100 percent tested.
Value depends on clock source:
• For an external clock generator, RESET duration is measured while RESET is asserted, VCC is valid, and the EXTAL input is
active and valid.
• For an internal oscillator, RESET duration is measured while RESET is asserted and VCC is valid. The specified timing
reflects the crystal oscillator stabilization time after power-up. This number is affected both by the specifications of the crystal
and other components connected to the oscillator and reflects worst case conditions.
• When the VCC is valid, but the other “required RESET duration” conditions (as specified above) have not been yet met, the
device circuitry is in an uninitialized 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.
VCCQH = 3.3 V ± 0.3 V, V CC = 1.8 V ± 0.1 V; TJ = –40°C to +100°C, CL = 50 pF.

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.
Timings 100 and107 are guaranteed by design, not tested.
All timings for 150 MHz are measured from 0.5 × VCCQH to 0.5 × VCCQH.
The WS number applies to the access in which the deassertion of WR occurs and assumes the next access uses a minimal
number of wait states.
Timing 118 is relative to the deassertion edge of RD or WR even if TA remains asserted.

2.4.5.2 DRAM Timing
The selection guides in Figure 2-12 and Figure 2-15 are for primary selection only. Final selection should be based
on the timing in the following tables. For example, the selection guide suggests that four wait states must be used
for 100 MHz operation with Page Mode DRAM. However, consulting the appropriate table, a designer can evaluate
whether fewer wait states might suffice by determining which timing prevents operation at 100 MHz, running the
chip at a slightly lower frequency (for example, 95 MHz), using faster DRAM (if it becomes available), and
manipulating control factors such as capacitive and resistive load to improve overall system performance.

The number of wait states for Page mode access is specified in the DRAM Control Register.
The refresh period is specified in the DRAM Control Register.
The asynchronous delays specified in the expressions are valid for the DSP56311.
All the timings are calculated for the worst case. Some of the timings are better for specific cases (for example, tPC equals 4 ×
TC for read-after-read or write-after-write sequences). An expression is used to compute the number listed as the minimum or
maximum 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 pageaccess.
RD deassertion always occurs after CAS deassertion; therefore, the restricted timing is tOFF and not tGZ .

tGZ
The number of wait states for Page mode access is specified in the DRAM Control Register.
The refresh period is specified in the DRAM Control Register.
The asynchronous delays specified in the expressions are valid for the DSP56311.
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 .

The number of wait states for an out-of-page access is specified in the DRAM Control Register.
The refresh period is specified in the DRAM Control Register.
Use the expression to compute the maximum or minimum value listed (or both if the expression includes ±) .
Either tRCH or tRRH must be satisfied for read cycles.
RD deassertion always occurs after CAS deassertion; therefore, the restricted timing is tOFF and not tGZ .

Bit 13 in the Operating Mode Register must be set to enable Asynchronous Arbitration mode.
At 150 MHz, Asynchronous Arbitration mode is recommended.
To guarantee timings 250 and 251, it is recommended that you assert non-overlapping BG inputs to different DSP56300
devices (on the same bus), as shown in Figure 2-19, where BG1 is the BG signal for one DSP56300 device while BG2 is the
BG signal for a second DSP56300 device.

Figure 2-19.
Asynchronous Bus Arbitration Timing
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 DSP56300 part may assume mastership and assert BB, for some time after BG is deasserted. 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
DSP56300 components that are potential masters on the same bus. If BG input is asserted before that time, and BG
is asserted and BB is deasserted, another DSP56300 component may 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 overlaps are avoided.

Notes:
See the Programmer’s Model section in the chapter on the HI08 in the DSP56311 User’s Manual.
In the timing diagrams below, the controls pins are drawn as active low. The pin polarity is programmable.
This timing is applicable only if two consecutive reads from one of these registers are executed.
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.
5. The read data strobe is HRD in the Dual Data Strobe mode and HDS in the Single Data Strobe mode.
6. The write data strobe is HWR in the Dual Data Strobe mode and HDS in the Single Data Strobe mode.
7. The host request is HREQ in the Single Host Request mode and HRRQ and HTRQ in the Double Host Request mode.
8. The “Last Data Register” is the register at address $7, which is the last location to be read or written in data transfers. This is
RXL/TXL in the Big Endian mode (HLEND = 0; HLEND is the Interface Control Register bit 7—ICR[7]), or RXH/TXH in the
Little Endian mode (HLEND = 1).
9. In this calculation, the host request signal is pulled up by a 4.7 kΩ resistor in the Open-drain mode.
10. VCCQH = 3.3 V ± 0.3 V, VCC = 1.8 V ± 0.1 V; TJ = –40°C to +100 °C, C L = 50 pF
11. 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 HREQ signal.
12. After the external host writes a new value to the ICR, the HI08 is ready for operation after three DSP clock cycles (3 × Tc).

For the internal clock, the external clock cycle is defined by the instruction cycle time (timing 7 in Table 2-5 on page 2-6) and
the ESSI Control Register.
The word-length-relative frame sync signal waveform operates the same way as the bit-length frame sync signal waveform,
but spreads from one serial clock before the first bit clock (same as the Bit Length Frame Sync signal) until the one before last
bit clock of the first word in the frame.
Periodically sampled and not 100 percent tested
VCCQH = 3.3 V ± 0.3 V, VCC = 1.8 V ± 0.1 V; TJ = –40°C to +100 °C, C L = 50 pF.
TXC (SCK Pin) = transmit clock
RXC (SC0 or SCK pin) = receive clock
FST (SC2 pin) = transmit frame sync
FSR (SC1 or SC2 pin) receive frame sync
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

2.4.10.2 With an Operating Frequency above 100 MHz
The following considerations can be helpful when GPIO is used for output or input with an operating frequency
above 100 MHz (that is, when CLKOUT is not available).
•
GPIO as Output:
— The time from fetch of the instruction that changes the GPIO pin to the actual change is seven core
clock cycles. This is true, assuming that the instruction is a one-cycle instruction and that there are no
pipeline stalls or any other pipeline delays.
— The maximum rise or fall time of a GPIO pin is 13 ns (TTL levels, assuming that the maximum of 50
pF load limit is met).
•
GPIO as Input—GPIO inputs are not synchronized with the core clock. When only one GPIO bit is polled,
this lack of synchronization presents no problem, since the read value can be either the previous value or
the new value of the corresponding GPIO pin. However, there is the risk of reading an intermediate state if:
— Two or more GPIO bits are treated as a coupled group (for example, four possible status states encoded
in two bits).
— The read operation occurs during a simultaneous change of GPIO pins (for example, the change of 00
to 11 may happen through an intermediate state of 01 or 10).
Therefore, when GPIO bits are read, the recommended practice is to poll continuously until two
consecutive read operations have identical results.

Notes:

Signal names are based on configured functionality. Most connections supply a single signal. Some connections provide a
signal with dual functionality, such as the MODx/IRQx pins that select an operating mode after RESET is deasserted but act as
interrupt lines during operation. Some signals have configurable polarity; these names are shown with and without overbars,
such as HAS/HAS. Some connections have two or more configurable functions; names assigned to these connections indicate
the function for a specific configuration. For example, connection N2 is data line H7 in non-multiplexed bus mode,
data/address line HAD7 in multiplexed bus mode, or GPIO line PB7 when the GPIO function is enabled for this pin. Unlike in
the TQFP package, most of the GND pins are connected internally in the center of the connection array and act as heat sink
for the chip. Therefore, except for GNDP and GNDP1 that support the PLL, other GND signals do not support individual
subsystems in the chip.
CLKOUT, BCLK, and BCLK are available only if the operating frequency is ≤100 MHz.

Design Considerations
4
This section describes various areas to consider when incorporating the DSP56311 device into a system design.
4.1 Thermal Design Considerations
An estimate of the chip junction temperature, T J, in ° C can be obtained from this equation:
Equation 1: T J = T A + ( P D × R θJ A )
Where:
TA
RθJA
PD
=
=
=
ambient temperature °C
package junction-to-ambient thermal resistance °C/W
power dissipation in package
Historically, thermal resistance has been expressed as the sum of a junction-to-case thermal resistance and a caseto-ambient thermal resistance, as in this equation:
Equation 2: R θJA = R θJC + R θCA
Where:
RθJA
RθJC
RθCA
=
=
=
package junction-to-ambient thermal resistance °C/W
package junction-to-case thermal resistance °C/W
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 percent 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 estimates 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 to determine the junction-to-case thermal resistance
in plastic packages.

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 the point at which the leads attach to the case.
If the temperature of the package case (TT) is determined by a thermocouple, thermal resistance is
computed from the value obtained by the equation (TJ – TT)/PD.
As noted earlier, 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 to determine the junction temperature from a case
thermocouple reading in forced convection environments. In natural convection, the use of the junction-to-case
thermal resistance to estimate junction temperature from a thermocouple reading on the case of the package will
yield an estimate of a junction temperature slightly higher 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 the surface temperature of the package is used. 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.
4.2 Electrical Design Considerations
CAUTION
This device contains protective circuitry to
guard against damage due to high static
voltage or electrical fields. However, normal
precautions are advised to avoid application
of any voltages higher than maximum rated
voltages to this high-impedance circuit.
Reliability of operation is enhanced if unused
inputs are tied to an appropriate logic voltage
level (for example, either GND or VCC).
Use the following list of recommendations to ensure 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 four 0.01–0.1 µF bypass capacitors for the core and PLL power and six 0.01–0.1 µF bypass
capacitors for I/O power positioned as closely 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 0.5 inch per capacitor lead.
Use at least a four-layer PCB with two inner layers for VCC and GND.

Power Consumption Considerations
•
•
•
•
•
•
•
•
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, IRQC, IRQD,
TA, and BG pins. Maximum PCB trace lengths on the order of 6 inches are recommended.
Consider all device loads as well as parasitic capacitance due to PCB traces when you calculate
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 (that is, not allowed to float) by CMOS levels except for the three pins with
internal pull-up resistors (TRST, TMS, DE).
Take special care to minimize noise levels on the VCCP, GNDP, and GNDP1 pins.
The following pins must be asserted during power-up: RESET and TRST. A stable EXTAL signal should be
supplied before deassertion of RESET. If the VCC reaches the required level before EXTAL is stable or
other “required RESET duration” conditions are met (see Table 2-7), the device circuitry can be in an
uninitialized state that may result in significant power consumption and heat-up. Designs should minimize
this condition to the shortest possible duration.
Ensure that during power-up, and throughout the DSP56311 operation, VCCQH is always higher or equal to
the VCC voltage level.
If multiple DSP devices are on the same board, check for cross-talk or excessive spikes on the supplies due
to synchronous operation of the devices.
The Port A data bus (D[0–23]), HI08, ESSI0, ESSI1, SCI, and timers all use internal keepers to maintain the
last output value even when the internal signal is tri-stated. Typically, no pull-up or pull-down resistors
should be used with these signal lines. However, if the DSP is connected to a device that requires pull-up
resistors (such as an MPC8260), the recommended resistor value is 10 KΩ or less. If more than one DSP
must be connected in parallel to the other device, the pull-up resistor value requirement changes as
follows:
— 2 DSPs = 7 KΩ or less
— 3 DSPs = 4 KΩ or less
— 4 DSPs = 3 KΩ or less
— 5 DSPs = 2 KΩ or less
— 6 DSPs = 1.5 KΩ or less
4.3 Power Consumption Considerations
Power dissipation is a key issue in portable DSP applications. Some of the factors affecting 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 this
formula:
Equation 3: I = C × V × f
Where:
C
V
f
=
=
=
node/pin capacitance
voltage swing
frequency of node/pin toggle
Example 4-1. Current Consumption
For a Port A address pin loaded with 50 pF capacitance, operating at 3.3 V, with a 66 MHz clock, toggling at its maximum possible rate (33
MHz), the current consumption is expressed in Equation 4.
DSP56311 Technical Data, Rev. 8
Freescale Semiconductor
4-3
Design Considerations
Equation 4: I = 50 × 10 – 12 × 3.3 × 33 × 10 6 = 5.48 mA
The maximum internal current (ICCImax) value reflects the typical possible switching of the internal buses on bestcase operation conditions—not necessarily a real application case. The typical internal current (ICCItyp) value
reflects the average switching of the internal buses on typical operating conditions. Perform the following steps for
applications that require very low current consumption:
1.
2.
3.
4.
5.
6.
7.
Set the EBD bit when you are 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.
Disable unused pin activity (for example, CLKOUT, XTAL).
One way to evaluate power consumption is to use a current-per-MIPS measurement methodology to minimize
specific board effects (that is, to compensate for measured board current not caused by the DSP). A benchmark
power consumption test algorithm is listed in Appendix A. Use the test algorithm, specific test current
measurements, and the following equation to derive the current-per-MIPS value.
Equation 5: ⁄ MIPS = I ⁄ MHz = ( ItypF2 – I typF1 ) ⁄ ( F2 – F1
Where:
ItypF2
ItypF1
F2
F1
=
=
=
=
current at F2
current at F1
high frequency (any specified operating frequency)
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.
4.4 PLL Performance Issues
The following explanations should be considered as general observations on expected PLL behavior. There is no
test that replicates these exact numbers. These observations were measured on a limited number of parts and were
not verified over the entire temperature and voltage ranges.
4.4.1
Phase Skew Performance
The phase skew of the PLL is defined as the time difference between the falling edges of EXTAL and CLKOUT for a
given capacitive load on CLKOUT, over the entire process, temperature and voltage ranges. As defined in Figure 22, External Clock Timing, on page 2-5 for input frequencies greater than 15 MHz and the MF ≤4, this skew is
greater than or equal to 0.0 ns and less than 1.8 ns; otherwise, this skew is not guaranteed. However, for MF < 10
and input frequencies greater than 10 MHz, this skew is between −1.4 ns and +3.2 ns.

Freescale Semiconductor
PLL Performance Issues
4.4.2
Phase Jitter Performance
The phase jitter of the PLL is defined as the variations in the skew between the falling edges of EXTAL and CLKOUT
for a given device in specific temperature, voltage, input frequency, MF, and capacitive load on CLKOUT. These
variations are a result of the PLL locking mechanism. For input frequencies greater than 15 MHz and MF ≤4, this
jitter is less than ±0.6 ns; otherwise, this jitter is not guaranteed. However, for MF < 10 and input frequencies
greater than 10 MHz, this jitter is less than ±2 ns.
DSP56311 Technical Data, Rev. 8
Freescale Semiconductor
4-5
Design Considerations
4.4.3
Frequency Jitter Performance
The frequency jitter of the PLL is defined as the variation of the frequency of CLKOUT. For small MF (MF < 10)
this jitter is smaller than 0.5 percent. For mid-range MF (10 < MF < 500) this jitter is between 0.5 percent and
approximately 2 percent. For large MF (MF > 500), the frequency jitter is 2–3 percent.
4.5 Input (EXTAL) Jitter Requirements
The allowed jitter on the frequency of EXTAL is 0.5 percent. If the rate of change of the frequency of EXTAL is slow
(that is, it does not jump between the minimum and maximum values in one cycle) or the frequency of the jitter is
fast (that is, it does not stay at an extreme value for a long time), then the allowed jitter can be 2 percent. The phase
and frequency jitter performance results are valid only if the input jitter is less than the prescribed values.
