MC9S12DP256B Device User Guide — V02.15 Section 1 Introduction 1.1 Overview The MC9S12DP256 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip peripherals including a 16-bit central processing unit (HCS12 CPU), 256K bytes of Flash EEPROM, 12K bytes of RAM, 4K bytes of EEPROM, two asynchronous serial communications interfaces (SCI), three serial peripheral interfaces (SPI), an 8-channel IC/OC enhanced capture timer, two 8-channel, 10-bit analog-to-digital converters (ADC), an 8-channel pulse-width modulator (PWM), a digital Byte Data Link Controller (BDLC), 29 discrete digital I/O channels (Port A, Port B, Port K and Port E), 20 discrete digital I/O lines with interrupt and wakeup capability, five CAN 2.0 A, B software compatible modules (MSCAN12), and an Inter-IC Bus. The MC9S12DP256 has full 16-bit data paths throughout. However, the external bus can operate in an 8-bit narrow mode so single 8-bit wide memory can be interfaced for lower cost systems. The inclusion of a PLL circuit allows power consumption and performance to be adjusted to suit operational requirements.

Every supply pair must be decoupled by a ceramic capacitor connected as near as possible to the corresponding pins(C1 - C6). Central point of the ground star should be the VSSR pin. Use low ohmic low inductance connections between VSS1, VSS2 and VSSR. VSSPLL must be directly connected to VSSR. Keep traces of VSSPLL, EXTAL and XTAL as short as possible and occupied board area for C7, C8, C11 and Q1 as small as possible. Do not place other signals or supplies underneath area occupied by C7, C8, C10 and Q1 and the connection area to the MCU. Central power input should be fed in at the VDDA/VSSA pins.

C: Those parameters are achieved by the design characterization by measuring a statistically relevant sample size across process variations. T: Those parameters are achieved by design characterization on a small sample size from typical devices under typical conditions unless otherwise noted. All values shown in the typical column are within this category. D: Those parameters are derived mainly from simulations. A.1.2 Power Supply The MC9S12DP256B utilizes several pins to supply power to the I/O ports, A/D converter, oscillator and PLL as well as the digital core. The VDDA, VSSA pair supplies the A/D converter and the resistor ladder of the internal voltage regulator. 87 For More Information On This Product, Go to: www.freescale.com Freescale MC9S12DP256B Device User Guide — V02.15 Semiconductor, Inc. The VDDX, VSSX, VDDR and VSSR pairs supply the I/O pins, VDDR supplies also the internal voltage regulator. VDD1, VSS1, VDD2 and VSS2 are the supply pins for the digital logic, VDDPLL, VSSPLL supply the oscillator and the PLL. VSS1 and VSS2 are internally connected by metal. VDDA, VDDX, VDDR as well as VSSA, VSSX, VSSR are connected by anti-parallel diodes for ESD protection. NOTE: Freescale Semiconductor, Inc... In the following context VDD5 is used for either VDDA, VDDR and VDDX; VSS5 is used for either VSSA, VSSR and VSSX unless otherwise noted. IDD5 denotes the sum of the currents flowing into the VDDA, VDDX and VDDR pins. VDD is used for VDD1, VDD2 and VDDPLL, VSS is used for VSS1, VSS2 and VSSPLL. IDD is used for the sum of the currents flowing into VDD1 and VDD2. A.1.3 Pins There are four groups of functional pins. A.1.3.1 5V I/O pins Those I/O pins have a nominal level of 5V. This class of pins is comprised of all port I/O pins, the analog inputs, BKGD and the RESET pins.The internal structure of all those pins is identical, however some of the functionality may be disabled. E.g. for the analog inputs the output drivers, pull-up and pull-down resistors are disabled permanently. A.1.3.2 Analog Reference This group is made up by the VRH and VRL pins. A.1.3.3 Oscillator The pins XFC, EXTAL, XTAL dedicated to the oscillator have a nominal 2.5V level. They are supplied by VDDPLL. A.1.3.4 TEST This pin is used for production testing only. A.1.3.5 VREGEN This pin is used to enable the on chip voltage regulator. 88 For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. MC9S12DP256B Device User Guide — A.1.4 Current Injection V02.15 Power supply must maintain regulation within operating VDD5 or VDD range during instantaneous and operating maximum current conditions. If positive injection current (Vin > VDD5) is greater than IDD5, the injection current may flow out of VDD5 and could result in external power supply going out of regulation. Ensure external VDD5 load will shunt current greater than maximum injection current. This will be the greatest risk when the MCU is not consuming power; e.g. if no system clock is present, or if clock rate is very low which would reduce overall power consumption. A.1.5 Absolute Maximum Ratings Absolute maximum ratings are stress ratings only. A functional operation under or outside those maxima is not guaranteed. Stress beyond those limits may affect the reliability or cause permanent damage of 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 VSS5 or VDD5).

The following constraints exist to obtain full-scale, full range results: VSSA ≤ VRL ≤ VIN ≤ VRH ≤ VDDA.

A.2.2 Factors influencing accuracy Three factors - source resistance, source capacitance and current injection - have an influence on the accuracy of the ATD. A.2.2.1 Source Resistance: Due to the input pin leakage current as specified in Table A-6 in conjunction with the source resistance there will be a voltage drop from the signal source to the ATD input. The maximum source resistance RS 97 For More Information On This Product, Go to: www.freescale.com Freescale MC9S12DP256B Device User Guide — V02.15 Semiconductor, Inc. specifies results in an error of less than 1/2 LSB (2.5mV) at the maximum leakage current. If device or operating conditions are less than worst case or leakage-induced error is acceptable, larger values of source resistance is allowed. A.2.2.2 Source Capacitance When sampling an additional internal capacitor is switched to the input. This can cause a voltage drop due to charge sharing with the external and the pin capacitance. For a maximum sampling error of the input voltage ≤ 1LSB, then the external filter capacitor, Cf ≥ 1024 * (CINS- CINN). A.2.2.3 Current Injection There are two cases to consider. Freescale Semiconductor, Inc... 1. A current is injected into the channel being converted. The channel being stressed has conversion values of $3FF ($FF in 8-bit mode) for analog inputs greater than VRH and $000 for values less than VRL unless the current is higher than specified as disruptive condition. 2. Current is injected into pins in the neighborhood of the channel being converted. A portion of this current is picked up by the channel (coupling ratio K), This additional current impacts the accuracy of the conversion depending on the source resistance. The additional input voltage error on the converted channel can be calculated as VERR = K * RS * IINJ, with IINJ being the sum of the currents injected into the two pins adjacent to the converted channel.

Detailed description of the startup behavior can be found in the Clock and Reset Generator (CRG) Block User Guide. Table A-14 Startup Characteristics Freescale Semiconductor, Inc...

They are also valid if the device is powered externally. After releasing the POR reset the oscillator and the clock quality check are started. If after a time tCQOUT no valid oscillation is detected, the MCU will start using the internal self clock. The fastest startup time possible is given by nuposc. A.5.1.2 SRAM Data Retention Provided an appropriate external reset signal is applied to the MCU, preventing the CPU from executing code when VDD5 is out of specification limits, the SRAM contents integrity is guaranteed if after the reset the PORF bit in the CRG Flags Register has not been set. A.5.1.3 External Reset When external reset is asserted for a time greater than PWRSTL the CRG module generates an internal reset, and the CPU starts fetching the reset vector without doing a clock quality check, if there was an oscillation before reset. 107 For More Information On This Product, Go to: www.freescale.com Freescale MC9S12DP256B Device User Guide — V02.15 A.5.1.4 Stop Recovery Semiconductor, Inc. Out of STOP the controller can be woken up by an external interrupt. A clock quality check as after POR is performed before releasing the clocks to the system. A.5.1.5 Pseudo Stop and Wait Recovery The recovery from Pseudo STOP and Wait are essentially the same since the oscillator was not stopped in both modes. The controller can be woken up by internal or external interrupts. After twrs the CPU starts fetching the interrupt vector. A.5.2 Oscillator Freescale Semiconductor, Inc... The device features an internal Colpitts oscillator. By asserting the XCLKS input during reset this oscillator can be bypassed allowing the input of a square wave. Before asserting the oscillator to the internal system clocks the quality of the oscillation is checked for each start from either power-on, STOP or oscillator fail. tCQOUT specifies the maximum time before switching to the internal self clock mode after POR or STOP if a proper oscillation is not detected. The quality check also determines the minimum oscillator start-up time tUPOSC. The device also features a clock monitor. A Clock Monitor Failure is asserted if the frequency of the incoming clock signal is below the Assert Frequency fCMFA.

A.5.3.2 Jitter Information The basic functionality of the PLL is shown in Figure A-2. With each transition of the clock fcmp, the deviation from the reference clock fref is measured and input voltage to the VCO is adjusted accordingly.The adjustment is done continuously with no abrupt changes in the clock output frequency. Noise, voltage, temperature and other factors cause slight variations in the control loop resulting in a clock jitter. This jitter affects the real minimum and maximum clock periods as illustrated in Figure A-3. 110 For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc.
