It combines, on a single chip, the processing power of a Digital Signal Processor (DSP) and the functionality of a microcontroller with a flexible set of peripherals to create an extremely cost-effective solution. Because of its low cost, configuration flexibility, and compact program code, the 56852 is well-suited for many applications. The 56852 includes many peripherals especially useful for low-end Internet appliance applications and low-end client applications such as telephony; portable devices; Internet audio; and point-of-sale systems such as noise suppression; ID tag readers; sonic/subsonic detectors; security access devices; remote metering; and sonic alarms. The 56800E core is based on a Harvard-style architecture consisting of three execution units operating in parallel, allowing as many as six operations per instruction cycle. The microprocessor-style programming model and optimized instruction set allow straightforward generation of efficient, compact DSP and control code. The instruction set is also highly efficient for C-Compilers, enabling rapid development of optimized control applications. The 56852 supports program execution from either internal or external memories. Two data operands can be accessed from the on-chip Data RAM per instruction cycle. The 56852 also provides two external dedicated interrupt lines, and up to 11 General Purpose Input/Output (GPIO) lines, depending on peripheral configuration. The 56852 includes 6K words of Program RAM, 4K words of Data RAM and 1K of Boot RAM. It also supports program execution from external memory. This controller also provides a full set of standard programmable peripherals that include one improved Synchronous Serial Interface (SSI) or one Serial Peripheral Interface (SPI), one Serial Communications Interface (SCI), and one Quad Timer. The SSI, SPI, SCI I/O and three chip selects can be used as General Purpose Input/Outputs when its primary function is not required. The SSI and SPI share I/O, so, at most, one of these two peripherals can be in use at any time. 1.3 State of the Art Development Environment • • Processor ExpertTM (PE) provides a Rapid Application Design (RAD) tool that combines easy-to-use component-based software application creation with an expert knowledge system.

D0–D15 are tri-stated when the external bus is inactive. C8 D14 MODE B A9 D15 MODE C C3 Description Chip Select 1 (CS1) —When enabled, a CSx signal is asserted for external memory accesses that fall within a programmable address range. Port A GPIO (1) —A general purpose IO pin. Chip Select 2 (CS2)—When enabled, a CSx signal is asserted for external memory accesses that fall within a programmable address range. Mode Select—During the bootstrap process the MODE A, MODE B, and MODE C pins select one of the eight bootstrap modes. These pins are sampled at the end of reset. Note: Any time POR and EXTERNAL resets are active, the state of MODE A, B and C pins get asynchronously transferred to the SIM Control Register [14:12] ($1FFF08) respectively. These bits determine the mode in which the part will boot up. Note: Software and COP resets do not update the SIM Control Register. E2 RD Output Bus Control– Read Enable (RD)—is asserted during external memory read cycles. When RD is asserted low, pins D0–D15 become inputs and an external device is enabled onto the data bus. When RD is deasserted high, the external data is latched inside the controller.

If an external clock source other than a crystal oscillator is used, EXTAL must be tied off. A7 XTAL Input/Output Crystal Oscillator Output (XTAL)—This output connects the internal crystal oscillator output to an external crystal. If an external clock source other than a crystal oscillator is used, XTAL must be used as the input. 56852 Technical Data, Rev. 8 Freescale Semiconductor 13 Table 3-1. 56852 Signal and Package Information for the 81-pin MAPBGA (Continued) Pin No. Signal Name Type Description D5 RESET Input Reset (RESET)—This input is a direct hardware reset on the processor. When RESET is asserted low, the controller is initialized and placed in the Reset state. A Schmitt trigger input is used for noise immunity. When the RESET pin is deasserted, the initial Chip Operating mode is latched from the D[15:13] pins. The internal reset signal will be deasserted synchronous with the internal clocks, after a fixed number of internal clocks. To ensure complete hardware reset, RESET and TRST should be asserted together. The only exception occurs in a debugging environment when a hardware reset is required and it is necessary not to reset the JTAG/Enhanced OnCE module. In this case, assert RESET, but do not assert TRST. C6 TCK Input Test Clock Input (TCK)—This input pin provides a gated clock to synchronize the test logic and shift serial data to the JTAG/Enhanced OnCE port. The pin is connected internally to a pull-down resistor. B7 TDI Input Test Data Input (TDI)—This input pin provides a serial input data stream to the JTAG/Enhanced OnCE port. It is sampled on the rising edge of TCK and has an on-chip pull-up resistor. A8 TDO Output Test Data Output (TDO)—This tri-statable output pin provides a serial output data stream from the JTAG/Enhanced OnCE port. It is driven in the Shift-IR and Shift-DR controller states, and changes on the falling edge of TCK. C7 TMS Input Test Mode Select Input (TMS)—This input pin is used to sequence the JTAG TAP controller’s state machine. It is sampled on the rising edge of TCK and has an on-chip pull-up resistor. Note: D6 TRST Input Always tie the TMS pin to VDD through a 2.2K resistor. Test Reset (TRST)—As an input, a low signal on this pin provides a reset signal to the JTAG TAP controller. To ensure complete hardware reset, TRST should be asserted whenever RESET is asserted. The only exception occurs in a debugging environment, since the Enhanced OnCE/JTAG module is under the control of the debugger. In this case it is not necessary to assert TRST when asserting RESET. Outside of a debugging environment RESET should be permanently asserted by grounding the signal, thus disabling the Enhanced OnCE/JTAG module on the device. Note: For normal operation, connect TRST directly to VSS. If the design is to be used in a debugging environment, TRST may be tied to VSS through a 1K resistor. B8 DE Input/Output Debug Even (DE)— is an open-drain, bidirectional, active low signal. As an input, it is a means of entering Debug mode of operation from an external command controller. As an output, it is a means of acknowledging that the chip has entered Debug mode. 56852 Technical Data, Rev. 8 14 Freescale Semiconductor General Characteristics Part 4 Specifications 4.1 General Characteristics The 56852 is fabricated in high-density CMOS with 5-volt tolerant TTL-compatible digital inputs. The term “5-volt tolerant” refers to the capability of an I/O pin, built on a 3.3V compatible process technology, to withstand a voltage up to 5.5V without damaging the device. Many systems have a mixture of devices designed for 3.3V and 5V power supplies. In such systems, a bus may carry both 3.3V and 5V- compatible I/O voltage levels (a standard 3.3V I/O is designed to receive a maximum voltage of 3.3V ±10% during normal operation without causing damage). This 5V-tolerant capability therefore offers the power savings of 3.3V I/O levels while being able to receive 5V levels without being damaged. Absolute maximum ratings given in Table 4-1 are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond these ratings may affect device reliability or cause permanent damage to the device. The 56852 DC/AC electrical specifications are preliminary and are from design simulations. These specifications may not be fully tested or guaranteed at this early stage of the product life cycle. Finalized specifications will be published after complete characterization and device qualifications have been completed. 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 voltage level. 56852 Technical Data, Rev. 8 Freescale Semiconductor 15 Table 4-1 Absolute Maximum Ratings Characteristic Supply voltage, core Supply voltage, IO Supply voltage, analog Digital input voltages Analog input voltages (XTAL, EXTAL) Current drain per pin excluding VDD, VSS, VDDA, VSSA,VDDIO, VSSIO Junction temperature Storage temperature range Symbol Min Max Unit VDD1 VSS – 0.3 VSS + 2.0 V VDDIO2 VSSIO – 0.3 VSSA – 0.3 VSSIO + 4.0 VDDA + 4.0 V VDDIO2 VIN VINA VSSIO – 0.3 VSSA – 0.3 VSSIO + 5.5 VDDA + 0.3 V I — 10 mA TJ -40 120 °C TSTG -55 150 °C 1.

The internally regulated voltage is typically 100mV less than VDD during ramp up until 2.5V is reached, at which time it self-regulates. 56852 Technical Data, Rev. 8 18 Freescale Semiconductor Supply Voltage Sequencing and Separation Cautions 150 EMI Mode5 MAC Mode1 120 IDD (mA) 90 60 30 0 20 40 60 80 100 120 Figure 4-1 Maximum Run IDDTOTAL vs. Frequency (see Notes 1. and 5. in Table 4-4) 4.3 Supply Voltage Sequencing and Separation Cautions DC Power Supply Voltage Figure 4-2 shows two situations to avoid in sequencing the VDD and VDDIO, VDDA supplies. 3.3V VDDIO, VDDA 2 1.8V Supplies Stable VDD 1 Time 0 Note: 1. VDD rising before VDDIO, VDDA 2. VDDIO, VDDA rising much faster than VDD Figure 4-2 Supply Voltage Sequencing and Separation Cautions 56852 Technical Data, Rev. 8 Freescale Semiconductor 19 VDD should not be allowed to rise early (1). This is usually avoided by running the regulator for the VDD supply (1.8V) from the voltage generated by the 3.3V VDDIO supply, see Figure 4-3. This keeps VDD from rising faster than VDDIO. VDD should not rise so late that a large voltage difference is allowed between the two supplies (2). Typically this situation is avoided by using external discrete diodes in series between supplies, as shown in Figure 4-3. The series diodes forward bias when the difference between VDDIO and VDD reaches approximately 2.1, causing VDD to rise as VDDIO ramps up. When the VDD regulator begins proper operation, the difference between supplies will typically be 0.8V and conduction through the diode chain reduces to essentially leakage current. During supply sequencing, the following general relationship should be adhered to: VDDIO > VDD > (VDDIO - 2.1V) In practice, VDDA is typically connected directly to VDDIO with some filtering.

To generate a reference frequency using the internal oscillator, a reference crystal must be connected between the EXTAL and XTAL pins. 4.5.1 Crystal Oscillator for Use with PLL The internal oscillator is designed to interface with a parallel-resonant crystal resonator in the frequency range specified for the external crystal in Table 4-6. In Figure 4-6 a typical crystal oscillator circuit is shown. Follow the crystal supplier’s recommendations when selecting a crystal, because crystal parameters determine the component values required to provide maximum stability and reliable start-up. The crystal and associated components should be mounted as close as possible to the EXTAL and XTAL pins to minimize output distortion and start-up stabilization time.

An externally supplied reference clock should be as free as possible from any phase jitter for the PLL to work correctly. The PLL is optimized for 4MHz input crystal. 2. This is the minimum time required after the PLL setup is changed to ensure reliable operation. 4.6 External Memory Interface Timing The External Memory Interface is designed to access static memory and peripheral devices. Figure 4-10 shows sample timing and parameters that are detailed in Table 4-7. The timing of each parameter consists of both a fixed delay portion and a clock related portion; as well as user controlled wait states. The equation: t = D + P * (M + W) should be used to determine the actual time of each parameter. The terms in the above equation are defined as: t parameter delay time D fixed portion of the delay, due to on-chip path delays. P the period of the system clock, which determines the execution rate of the part (i.e. when the device is operating at 120 MHz, P = 8.33 ns). M Fixed portion of a clock period inherent in the design. This number is adjusted to account for possible clock duty cycle derating. W the sum of the applicable wait state controls. See the “Wait State Controls” column of Table 4-7 for the applicable controls for each parameter. See the EMI chapter of the 83x Peripheral Manual for details of what each wait state field controls. 56852 Technical Data, Rev. 8 Freescale Semiconductor 23 Some of the parameters contain two sets of numbers. These parameters have two different paths and clock edges that must be considered. Check both sets of numbers and use the smaller result. The appropriate entry may change if the operating frequency of the part changes. The timing of write cycles is different when WWS = 0 than when WWS > 0. Therefore, some parameters contain two sets of numbers to account for this difference. The “Wait States Configuration” column of Table 4-7 should be used to make the appropriate selection.

The part is then put into run mode and tclk assumes the period of the source clock, txtal, textal or tosc. 4. The minimum is specified for the duration of an edge-sensitive IRQA interrupt required to recover from the Stop state. This is not the minimum required so that the IRQA interrupt is accepted. 5. The interrupt instruction fetch is visible on the pins only in Mode 3. 6. Fast stop mode: Fast stop recovery applies when external clocking is in use (direct clocking to XTAL) or when fast stop mode recovery is requested (OMR bit 6 is set to 1). In both cases the PLL and the master clock are unaffected by stop mode entry. Recovery takes one less cycle and tclk will continue same value it had before stop mode was entered. 7. Normal stop mode: As a power saving feature, normal stop mode disables and bypasses the PLL. Stop mode will then shut down the master clock, recovery will take an extra cycle (to restart the clock), and tclk will resume at the input clock source rate. 8.

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 the 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 definitions for determining the junction-to-case thermal resistance in plastic packages: • • • Measure the thermal resistance 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. This is done to minimize temperature variation across the surface. Measure the thermal resistance from the junction to where the leads are attached to the case. This definition is approximately equal to a junction to board thermal resistance. Use the value obtained by the equation (TJ – TT)/PD where TT is the temperature of the package case determined by a thermocouple. 56852 Technical Data, Rev. 8 Freescale Semiconductor 43 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. 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. 6.2 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 voltage level. Use the following list of considerations to assure correct operation: • Provide a low-impedance path from the board power supply to each VDD pin on the device, and from the board ground to each VSS (GND) pin. • The minimum bypass requirement is to place six 0.01–0.1μF capacitors positioned as close as possible to the package supply pins. The recommended bypass configuration is to place one bypass capacitor on each of the ten VDD/VSS pairs, including VDDA/VSSA. • Ensure that capacitor leads and associated printed circuit traces that connect to the chip VDD and VSS (GND) pins are less than 0.5 inch per capacitor lead. Use at least a four-layer Printed Circuit Board (PCB) with two inner layers for VDD and GND. • • • • Bypass the VDD and GND layers of the PCB with approximately 100μF, preferably with a high-grade capacitor such as a tantalum capacitor. Because the device’s output signals have fast rise and fall times, PCB trace lengths should be minimal. 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 VDD and GND circuits. • All inputs must be terminated (i.e., not allowed to float) using CMOS levels. 56852 Technical Data, Rev. 8 44 Freescale Semiconductor Electrical Design Considerations • Take special care to minimize noise levels on the VDDA and VSSA pins. • • When using Wired-OR mode on the SPI or the IRQx pins, the user must provide an external pull-up device. Designs that utilize the TRST pin for JTAG port or Enhance OnCE module functionality (such as development or debugging systems) should allow a means to assert TRST whenever RESET is asserted, as well as a means to assert TRST independently of RESET. Designs that do not require debugging functionality, such as consumer products, should tie these pins together. The internal POR (Power on Reset) will reset the part at power on with reset asserted or pulled high but requires that TRST be asserted at power on. • 56852 Technical Data, Rev. 8 Freescale Semiconductor 45 Part 7 Ordering Information Table 7-1 lists the pertinent information needed to place an order.
