The filter shown in Figure 2 should be connected between the board VDD and the PLLVDD pins. The resistor and capacitors should be placed as close to the dedicated PLLVDD pin as possible. 10 Ω Board IVDD PLL VDD Pin 10 µF 0.1 µF GND Figure 2. System PLL VDD Power Filter 3.2 USB Power Filtering To minimize noise, external filters are required for each of the USB power pins. The filter shown in Figure 3 should be connected between the board EVDD and the USBVDD pin. The resistor and capacitors should be placed as close to the dedicated USBVDD pin as possible. 0Ω Board EVDD USB VDD Pin 10 µF 0.1 µF GND Figure 3. USB VDD Power Filter NOTE In addition to the above filter circuitry, a 0.01 F capacitor is also recommended in parallel with those shown. MCF5227x ColdFire® Microprocessor Data Sheet, Rev. 8 Freescale Semiconductor 5 Hardware Design Considerations 3.3 ADC Power Filtering To minimize noise, an external filters is required for the ADCVDD power pin. The filter shown in Figure 4 should be connected between the board EVDD and the ADCVDD pin. The resistor and capacitors should be placed as close to the dedicated ADCVDD pin as possible. 0Ω Board EVDD ADC VDD Pin 10 µF 0.1 µF GND Figure 4. ADC VDD Power Filter 3.4 Supply Voltage Sequencing The relationship between SDVDD and EVDD is non-critical during power-up and power-down sequences. Both SDVDD (2.5V or 3.3V) and EVDD are specified relative to IVDD. 3.4.1 Power Up Sequence If EVDD/SDVDD are powered up with IVDD at 0 V, then the sense circuits in the I/O pads will cause all pad output drivers connected to the EVDD/SDVDD to be in a high impedance state. There is no limit on how long after EVDD/SDVDD powers up before IVDD must powered up. IVDD should not lead the EVDD, SDVDD or PLLVDD by more than 0.4 V during power ramp-up, or there will be high current in the internal ESD protection diodes. The rise times on the power supplies should be slower than 500 us to avoid turning on the internal ESD protection clamp diodes. 3.4.2 Power Down Sequence If IVDD/PLLVDD are powered down first, then sense circuits in the I/O pads will cause all output drivers to be in a high impedance state. There is no limit on how long after IVDD and PLLVDD power down before EVDD or SDVDD must power down. IVDD should not lag EVDD, SDVDD, or PLLVDD going low by more than 0.4 V during power down or there will be undesired high current in the ESD protection diodes. There are no requirements for the fall times of the power supplies. The recommended power down sequence is as follows: 1. 2. Drop IVDD/PLLVDD to 0 V. Drop EVDD/SDVDD supplies.

The direction column is the direction for the primary function of the pin only. Refer to Section 4, “Pin Assignments and Reset States,” for package diagrams. For a more detailed discussion of the MCF5227x signals, consult the MCF52277 Reference Manual (MCF52277RM). NOTE In this table and throughout this document a single signal within a group is designated without square brackets (i.e., FB_A23), while designations for multiple signals within a group use brackets (i.e., FB_A[23:21]) and is meant to include all signals within the two bracketed numbers when these numbers are separated by a colon. NOTE The primary functionality of a pin is not necessarily its default functionality. Most pins that are muxed with GPIO will default to their GPIO functionality.

This section contains detailed information on DC/AC electrical characteristics and AC timing specifications. The electrical specifications are preliminary and are from previous designs or design simulations. These specifications may not be fully tested or guaranteed at this early stage of the product life cycle, however for production silicon these specifications will be met. Finalized specifications will be published after complete characterization and device qualifications have been completed.

Continued operation at these levels may affect device reliability or cause permanent damage to the device. This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, it is advised that normal precautions be taken 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 (e.g., either VSS or EVDD). Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate resistance values for positive and negative clamp voltages, then use the larger of the two values. All functional non-supply pins are internally clamped to VSS and EVDD. Power supply must maintain regulation within operating EVDD range during instantaneous and operating maximum current conditions. If positive injection current (Vin > EVDD) is greater than IDD, the injection current may flow out of EVDD and could result in external power supply going out of regulation. Insure external EVDD load will shunt current greater than maximum injection current. This will be the greatest risk when the MCU is not consuming power (ex; no clock). Power supply must maintain regulation within operating EVDD range during instantaneous and operating maximum current conditions.

Freescale recommends the use of θJmA and power dissipation specifications in the system design to prevent device junction temperatures from exceeding the rated specification. System designers should be aware that device junction temperatures can be significantly influenced by board layout and surrounding devices. Conformance to the device junction temperature specification can be verified by physical measurement in the customer’s system using the Ψjt parameter, the device power dissipation, and the method described in EIA/JESD Standard 51-2.

An approximate relationship between PD and TJ (if PI/O is neglected) is: K P D = --------------------------------( T J + 273 ° C ) Eqn. 2 Solving equations 1 and 2 for K gives: 2 K = P D × ( T A × 273°C ) + Q JMA × P D Eqn. 3 where K is a constant pertaining to the particular part. K can be determined from Equation 3 by measuring PD (at equilibrium) for a known TA. Using this value of K, the values of PD and TJ can be obtained by solving Equation 1 and Equation 2 iteratively for any value of TA.

When the PLL is enabled, the minimum system frequency (fsys) is 37.5 MHz. This parameter is guaranteed by characterization before qualification rather than 100% tested.

Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum fsys. Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise injected into the PLL circuitry via PLL VDD, EVDD, and VSS and variation in crystal oscillator frequency increase the Cjitter percentage for a given interval. 5.6 ASP Electrical Characteristics Table 12 lists the electrical specifications for the ASP module.

This unit of measure approximately relates the error voltage to the observed error in conversion (code error), and is useful for systemic errors such as differential non-linearity. A 2.56-V input on an ADC with ± 3 lsb of error could read between 0x1FD and 0x203. This unit is by far the most common terminology and will be the preferred unit used for error representation. A bit is a unit equal to the log (base2) of the error voltage normalized to the resolution of the ADC. An error of N bits corresponds to 2N lsb of error. This measure is easily confused with lsb and is hard to extrapolate between integer values. 5.7 5.7.1 External Interface Timing Specifications FlexBus A multi-function external bus interface called FlexBus is provided with basic functionality to interface to slave-only devices up to a maximum bus frequency of 66MHz. It can be directly connected to asynchronous or synchronous devices such as external boot ROMs, flash memories, gate-array logic, or other simple target (slave) devices with little or no additional circuitry. For asynchronous devices a simple chip-select based interface can be used. All processor bus timings are synchronous; that is, input setup/hold and output delay are given in respect to the rising edge of a reference clock, FB_CLK. The FB_CLK frequency may be the same as the internal system bus frequency or an integer divider of that frequency. The following timing numbers indicate when data will be latched or driven onto the external bus, relative to the Flexbus output clock, FB_CLK. All other timing relationships can be derived from these values. Table 13.

Please consult the device reference manual for more information. NOTE The processor drives the data lines during the first clock cycle of the transfer with the full 32-bit address. This may be ignored by standard connected devices using non-multiplexed address and data buses. However, some applications may find this feature beneficial. The address and data busses are muxed between the FlexBus and SDRAM controller. At the end of the read and write bus cycles the address signals are indeterminate.

Flexbus Write Timing 5.7.2 SDRAM Bus The SDRAM controller supports accesses to main SDRAM memory from any internal master. It supports either standard SDRAM or double data rate (DDR) SDRAM, but it does not support both at the same time. 126.96.36.199 SDR SDRAM AC Timing Specifications The following timing numbers indicate when data will be latched or driven onto the external bus, relative to the memory bus clock, when operating in SDR mode on write cycles and relative to SD_DQS on read cycles. The device’s SDRAM controller is a DDR controller that has an SDR mode. Because it is designed to support DDR, a DQS pulse must still be supplied to the device for each data beat of an SDR read. The processor accomplishes this by asserting a signal named SD_SDR_DQS during read cycles. Care must be taken during board design to adhere to the following guidelines and specs with regard to the SD_SDR_DQS signal and its usage. Table 14.

Notes 6 7 The device supports same frequency of operation for both FlexBus and SDRAM clock operates as that of the internal bus clock. Please see the PLL chapter of the device reference manual for more information on setting the SDRAM clock rate. SD_CLK is one SDRAM clock in ns. Pulse width high plus pulse width low cannot exceed min and max clock period. SD_SDR_DQS is designed to pulse 0.25 clock before the rising edge of the memory clock. This is a guideline only. Subtle variation from this guideline is expected. SD_SDR_DQS will only pulse during a read cycle and one pulse will occur for each data beat. SD_DQS is designed to pulse 0.25 clock before the rising edge of the memory clock. This spec is a guideline only. Subtle variation from this guideline is expected. SD_DQS will only pulse during a read cycle and one pulse will occur for each data beat. The SD_DQS pulse is designed to be 0.5 clock in width. The timing of the rising edge is most important. The falling edge does not affect the memory controller. Since a read cycle in SDR mode still uses the DQS circuit within the device, it is critical that the data valid window be centered 1/4 clk after the rising edge of DQS. Ensuring that this happens will result in successful SDR reads. The input setup spec is provided as guidance.

FlexBus and SDRAM clock operate at the same frequency as the internal bus clock. SD_CLK is one SDRAM clock in ns. Pulse-width high plus pulse-width low cannot exceed minimum or maximum clock period. Command output valid should be one-half the memory bus clock (SD_CLK) plus some minor adjustments for process, temperature, and voltage variations. This specification relates to the required input setup time of today’s DDR memories. The device’s output setup should be larger than the input setup of the DDR memories. If it is not larger, then the input setup on the memory will be in violation. MEM_DATA[31:24] is relative to MEM_DQS, MEM_DATA[23:16] is relative to MEM_DQS, MEM_DATA[15:8] is relative to MEM_DQS, and MEM_DATA[7:0] is relative MEM_DQS. The first data beat will be valid before the first rising edge of DQS and after the DQS write preamble. The remaining data beats will be valid for each subsequent DQS edge. This specification relates to the required hold time of today’s DDR memories. MEM_DATA[31:24] is relative to MEM_DQS, MEM_DATA[23:16] is relative to MEM_DQS, MEM_DATA[15:8] is relative to MEM_DQS, and MEM_DATA[7:0] is relative MEM_DQS. Data input skew is derived from each DQS clock edge. It begins with a DQS transition and ends when the last data line becomes valid. This input skew must include DDR memory output skew and system-level board skew (due to routing or other factors). Data input hold is derived from each DQS clock edge. It begins with a DQS transition and ends when the first data line becomes invalid.

The I2C interface is designed to scale the actual data transition time to move it to the middle of the SCL low period. The actual position is affected by the prescale and division values programmed into the IFDR; however, the numbers given in Table 29 are minimum values. 2 Because I2C_SCL and I2C_SDA are open-collector-type outputs, which the processor can only actively drive low, the time I2C_SCL or I2C_SDA take to reach a high level depends on external signal capacitance and pull-up resistor values. 3 Specified at a nominal 50-pF load.
