The MC9S12DT256 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. 1.2 Features • HCS12 Core – 16-bit HCS12 CPU i.

The following rules must be observed: • • • • • • • 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. 83 MC9S12DT256 Device User Guide — V03.07 Figure 20-1 Recommended PCB Layout for 112LQFP Colpitts Oscillator VREGEN VDDX C6 VSSX VSSA C3 VDDA VDD1 C1 VSS1 VSS2 C2 VDD2 VSSR C4 VDDR C5 C9 R1 C10 C8 Q1 VSSPLL VDDPLL C7 C11 84 MC9S12DT256 Device User Guide — V03.07 Figure 20-2 Recommended PCB Layout for 80QFP Colpitts Oscillator VDDX C6 VREGEN VSSX VSSA C3 VDDA VDD1 VSS2 C1 C2 VSS1 VDD2 VSSR C4 C5 VDDR C11 C8 C7 Q1 C10 R1 C9 VSSPLL VDDPLL 85 MC9S12DT256 Device User Guide — V03.07 Figure 20-3 Recommended PCB Layout for 112LQFP Pierce Oscillator VREGEN VDDX C6 VSSX VSSA C3 VDDA VDD1 C1 VSS1 VSS2 C2 VDD2 VSSR R3 C5 R2 Q1 C9 C10 C8 C7 VSSPLL C4 VDDR VDDPLL R1 86 MC9S12DT256 Device User Guide — V03.07 Figure 20-4 Recommended PCB Layout for 80QFP Pierce Oscillator VDDX C6 VREGEN VSSX VSSA C3 VDDA VDD1 VSS2 C1 C2 VSS1 VDD2 VSSPLL VSSR C4 C5 VDDR R2 Q1 C8 C7 R3 C10 R1 C9 VSSPLL VDDPLL 87 MC9S12DT256 Device User Guide — V03.07 88 MC9S12DT256 Device User Guide — V03.07 Appendix A Electrical Characteristics A.1 General NOTE: The electrical characteristics given in this section are preliminary and should be used as a guide only.

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. This classification is shown in the column labeled “C” in the parameter tables where appropriate. A.1.2 Power Supply The MC9S12DT256 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. 89 MC9S12DT256 Device User Guide — V03.07 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: 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. 90 MC9S12DT256 Device User Guide — V03.07 A.1.4 Current Injection 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 device contains an internal voltage regulator to generate the logic and PLL supply out of the I/O supply. The absolute maximum ratings apply when the device is powered from an external source. 3. All digital I/O pins are internally clamped to VSSX and VDDX, VSSR and VDDR or VSSA and VDDA. 4. Those pins are internally clamped to VSSPLL and VDDPLL. 5. This pin is clamped low to VSSR, but not clamped high. This pin must be tied low in applications. A.1.6 ESD Protection and Latch-up Immunity All ESD testing is in conformity with CDF-AEC-Q100 Stress test qualification for Automotive Grade Integrated Circuits. During the device qualification ESD stresses were performed for the Human Body Model (HBM), the Machine Model (MM) and the Charge Device Model. A device will be defined as a failure if after exposure to ESD pulses the device no longer meets the device specification. Complete DC parametric and functional testing is performed per the applicable device specification at room temperature followed by hot temperature, unless specified otherwise in the device specification.

A.1.10.1 Measurement Conditions All measurements are without output loads. Unless otherwise noted the currents are measured in single chip mode, internal voltage regulator enabled and at 25MHz bus frequency using a 4MHz oscillator in Colpitts mode. Production testing is performed using a square wave signal at the EXTAL input. A.1.10.2 Additional Remarks In expanded modes the currents flowing in the system are highly dependent on the load at the address, data and control signals as well as on the duty cycle of those signals. No generally applicable numbers can be 97 MC9S12DT256 Device User Guide — V03.07 given. A very good estimate is to take the single chip currents and add the currents due to the external loads.

A.2.1 ATD Operating Characteristics The Table A-8 shows conditions under which the ATD operates. The following constraints exist to obtain full-scale, full range results: VSSA ≤ VRL ≤ VIN ≤ VRH ≤ VDDA. This constraint exists since the sample buffer amplifier can not drive beyond the power supply levels that it ties to. If the input level goes outside of this range it will effectively be clipped.

Full accuracy is not guaranteed when differential voltage is less than 4.50V 2. The minimum time assumes a final sample period of 2 ATD clocks cycles while the maximum time assumes a final sample period of 16 ATD clocks. 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 99 MC9S12DT256 Device User Guide — V03.07 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. 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.

A.3.1 NVM timing The time base for all NVM program or erase operations is derived from the oscillator. A minimum oscillator frequency fNVMOSC is required for performing program or erase operations. The NVM modules do not have any means to monitor the frequency and will not prevent program or erase operation at frequencies above or below the specified minimum. Attempting to program or erase the NVM modules at a lower frequency a full program or erase transition is not assured. The Flash and EEPROM program and erase operations are timed using a clock derived from the oscillator using the FCLKDIV and ECLKDIV registers respectively. The frequency of this clock must be set within the limits specified as fNVMOP. The minimum program and erase times shown in Table A-11 are calculated for maximum fNVMOP and maximum fbus. The maximum times are calculated for minimum fNVMOP and a fbus of 2MHz. A.3.1.1 Single Word Programming The programming time for single word programming is dependant on the bus frequency as a well as on the frequency fNVMOP and can be calculated according to the following formula. 1 1 t swpgm = 9 ⋅ --------------------- + 25 ⋅ ---------f NVMOP f bus A.3.1.2 Burst Programming This applies only to the Flash where up to 32 words in a row can be programmed consecutively using burst programming by keeping the command pipeline filled. The time to program a consecutive word can be calculated as: 1 1 t bwpgm = 4 ⋅ --------------------- + 9 ⋅ ---------f NVMOP f bus The time to program a whole row is: t brpgm = t swpgm + 31 ⋅ t bwpgm Burst programming is more than 2 times faster than single word programming. 103 MC9S12DT256 Device User Guide V03.07 A.3.1.3 Sector Erase Erasing a 512 byte Flash sector or a 4 byte EEPROM sector takes: 1 t era ≈ 4000 ⋅ --------------------f NVMOP The setup time can be ignored for this operation. A.3.1.4 Mass Erase Erasing a NVM block takes: 1 t mass ≈ 20000 ⋅ --------------------f NVMOP The setup time can be ignored for this operation. A.3.1.5 Blank Check The time it takes to perform a blank check on the Flash or EEPROM is dependant on the location of the first non-blank word starting at relative address zero.
