Signal Pins 2.2 Signal Pins After reset, each pin is configured for its primary function (listed first). In the 56F8122, after reset, each pin must be configured for the desired function. The initialization software will configure each pin for the function listed first for each pin, as shown in Table 2-2. Any alternate functionality must be programmed. Note: Signals in italics are not available in the 56F8122 device.
Table 2-2 Signal and Package Information for the 48-Pin LQFP Signal Name Pin No. Type State During Reset EXTAL 32 Input/ Input Signal Description External Crystal Oscillator Input — This input can be connected to an 8MHz external crystal. If an external clock is used, XTAL must be used as the input and EXTAL connected to VSS. The input clock can be selected to provide the clock directly to the core. This input clock can also be selected as the input clock for the on-chip PLL.

Part 3 On-Chip Clock Synthesis (OCCS) 3.1 Introduction Refer to the OCCS chapter of the 56F8300 Peripheral User Manual for a full description of the OCCS. The material contained here identifies the specific features of the OCCS design. 3.2 External Clock Operation The system clock can be derived from an external crystal, ceramic resonator or an external system clock signal.
External Clock Operation 3.2.2 Ceramic Resonator (Default) It is also possible to drive the internal oscillator with a ceramic resonator, assuming the overall system design can tolerate the reduced signal integrity. A typical ceramic resonator circuit is shown in Figure 3-2. Refer to the supplier’s recommendations when selecting a ceramic resonator and associated components. The resonator and components should be mounted as near as possible to the EXTAL and XTAL pins.
3.3 Use of On-Chip Relaxation Oscillator An internal relaxtion oscillator can supply the reference frequency when an external frequency source of crystal is not used. During a boot or reset sequence, the relaxation oscillator is enabled by default, and the PRECS bit in the PLLCR word is set to 0. If an external oscillator is connected, the relaxation oscillator can be deselected instead by setting the PRECS bit in the PLLCR to 1.

The maximum master clock frequency is 120MHz. Peripheral and system clocks are generated at half the master clock frequency and therefore at a maximum 60MHz.

Both put the CPU to sleep. For lowest power consumption in Stop mode, the PLL can be shut down. This must be done explicitly before entering Stop mode, since there is no automatic mechanism for this.
Operation with Security Enabled Part 7 Security Features The 56F8322/56F8122 offer security features intended to prevent unauthorized users from reading the contents of the Flash Memory (FM) array. The Flash security consists of several hardware interlocks that block the means by which an unauthorized user could gain access to the Flash array. However, part of the security must lie with the user’s code.
Proper implementation of Flash security requires that no access to the EOnCE port is provided when security is enabled. The 56800E core has an input which disables reading of internal memory via the JTAG/EOnCE. The FM sets this input at reset to a value determined by the contents of the FM security bytes. 7.2.3 Flash Lockout Recovery If a user inadvertently enables Flash security on the device, a built-in lockout recovery mechanism can be used to reenable access to the device.
Flash Access Blocking Mechanisms EXAMPLE 1: If the system clock is the 8MHz crystal frequency because the PLL has not been set up, the input clock will be below 12.8MHz, so PRDIV8=FM_CLKDIV[6]=0. Using the following equation yields a DIV value of 19 for a clock of 200kHz, and a DIV value of 20 for a clock of 190kHz. This translates into an FM_CLKDIV[6:0] value of $13 or $14, respectively.

Figure 10-20 ADC Absolute Error Over Processing and Temperature Extremes Before and After Calibration for VDCin = 0.60V and 2.70V Note: The absolute error data shown in the graphs above reflects the effects of both gain error and offset error. The data was taken on 15 parts: three each from four processing corner lots as well as three from one nominally processed lot, each at three temperatures: -40°C, 27°C, and 150°C (giving the 45 data points shown above), for two input DC voltages: 0.60V and 2.70V.
Equivalent Circuit for ADC Inputs 10.16 Equivalent Circuit for ADC Inputs Figure 10-21 illustrates the ADC input circuit during sample and hold. S1 and S2 are always open/closed at the same time that S3 is closed/open. When S1/S2 closed & S3 open, one input of the sample and hold circuit moves to (VREFH-VREFLO)/2, while the other charges to the analog input voltage.
B, the internal [state-dependent component], reflects the supply current required by certain on-chip resources only when those resources are in use. These include RAM, Flash memory and the ADCs. C, the internal [dynamic component], is classic C*V2*F CMOS power dissipation corresponding to the 56800E core and standard cell logic. D, the external [dynamic component], reflects power dissipated on-chip as a result of capacitive loading on the external pins of the chip.

Part 12 Design Considerations 12.1 Thermal Design Considerations An estimation of the chip junction temperature, TJ, can be obtained from the equation: TJ = TA + (RθJΑ x PD) where: TA = Ambient temperature for the package (oC) RθJΑ = Junction to ambient thermal resistance (oC/W) PD = Power dissipation in the package (W) The junction to ambient thermal resistance is an industry-standard value that provides a quick and easy estimation of thermal performance.
Electrical Design Considerations The thermal characterization parameter is measured per JESD51-2 specification using a 40-gauge type T thermocouple epoxied to the top center of the package case. The thermocouple should be positioned so that the thermocouple junction rests on the package. A small amount of epoxy is placed over the thermocouple junction and over about 1mm of wire extending from the junction.
• • 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 VSS circuits.
