This structure allows up to four bus masters to access different bus slaves simultaneously, while providing arbitration among the bus masters when they access the same slave. 2.1 System features The following sections describe the high-level system features. 6 NXP Semiconductors Kinetis KE1xF with up to 512 KB Flash, Rev. 4, 06/2019 Overview 2.1.1 ARM Cortex-M4 core The ARM Cortex-M4 is the member of the Cortex M Series of processors targeting microcontroller cores focused on very cost sensitive, deterministic, interrupt driven environments. The Cortex M4 processor is based on the ARMv7 Architecture and Thumb®-2 ISA and is upward compatible with the Cortex M3, Cortex M1, and Cortex M0 architectures. Cortex M4 improvements include an ARMv7 Thumb-2 DSP (ported from the ARMv7-A/R profile architectures) providing 32-bit instructions with SIMD (single instruction multiple data) DSP style multiply-accumulates and saturating arithmetic. 2.1.2 NVIC The Nested Vectored Interrupt Controller supports nested interrupts and 16 priority levels for interrupts. In the NVIC, each source in the IPR registers contains 4 bits. It also differs in number of interrupt sources and supports 240 interrupt vectors. The Cortex-M family uses a number of methods to improve interrupt latency . It also can be used to wake the MCU core from Wait and VLPW modes. 2.1.3 AWIC The asynchronous wake-up interrupt controller (AWIC) is used to detect asynchronous wake-up events in Stop mode and signal to clock control logic to resume system clocking. After clock restarts, the NVIC observes the pending interrupt and performs the normal interrupt or event processing. The AWIC can be used to wake MCU core from Partial Stop, Stop and VLPS modes. Wake-up sources for this SoC are listed as below: Table 2.

The flash memory is divided into equal size segments that provide protection to proprietary software libraries. The protection of these Kinetis KE1xF with up to 512 KB Flash, Rev. 4, 06/2019 11 NXP Semiconductors Overview segments is controlled as the FAC provides a cycle-by-cycle evaluation of the access rights for each transaction routed to the on-chip flash memory. Configurability allows an increasing number of protected segments while supporting two levels of vendors adding their proprietary software to a device. 2.1.7.2 Error-correcting code (ECC) The ECC detection is also supported on Flash and SRAM memories. It supports auto correction of one-bit error and reporting more than one-bit error. 2.1.8 Power management The Power Management Controller (PMC) expands upon ARM’s operational modes of Run, Sleep, and Deep Sleep, to provide multiple configurable modes. These modes can be used to optimize current consumption for a wide range of applications. The WFI or WFE instruction invokes a Wait or a Stop mode, depending on the current configuration. For more information on ARM’s operational modes, See the ARM® Cortex® User Guide. The PMC provides High Speed Run (HSRUN), Normal Run (RUN), and Very Low Power Run (VLPR) configurations in ARM’s Run operation mode. In these modes, the MCU core is active and can access all peripherals. The difference between the modes is the maximum clock frequency of the system and therefore the power consumption. The configuration that matches the power versus performance requirements of the application can be selected. The PMC provides Wait (Wait) and Very Low Power Wait (VLPW) configurations in ARM’s Sleep operation mode. In these modes, even though the MCU core is inactive, all of the peripherals can be enabled and operate as programmed. The difference between the modes is the maximum clock frequency of the system and therefore the power consumption. The PMC provides Stop (Stop), Very Low Power Stop (VLPS) configurations in ARM’s Deep Sleep operational mode. In these modes, the MCU core and most of the peripherals are disabled. Depending on the requirements of the application, different portions of the analog, logic, and memory can be retained or disabled to conserve power. 12 NXP Semiconductors Kinetis KE1xF with up to 512 KB Flash, Rev. 4, 06/2019 Overview The Nested Vectored Interrupt Controller (NVIC), the Asynchronous Wake-up Interrupt Controller (AWIC) are used to wake up the MCU from low power states. The NVIC is used to wake up the MCU core from WAIT and VLPW modes. The AWIC is used to wake up the MCU core from STOP and VLPS modes. For additional information regarding operational modes, power management, the NVIC, AWIC, please refer to the Reference Manual. The following table provides information about the state of the peripherals in the various operational modes and the modules that can wake MCU from low power modes. Table 5. Peripherals states in different operational modes Core mode Run mode Sleep mode Deep sleep Device mode Descriptions High Speed Run In HSRun mode, MCU is able to operate at a faster frequency, and all device modules are operational. Run In Run mode, all device modules are operational. Very Low Power Run In VLPR mode, all device modules are operational at a reduced frequency except the Low Voltage Detect (LVD) monitor, which is disabled. Wait In Wait mode, all peripheral modules are operational. The MCU core is placed into Sleep mode. Very Low Power Wait In VLPW mode, all peripheral modules are operational at a reduced frequency except the Low Voltage Detect (LVD) monitor, which is disabled. The MCU core is placed into Sleep mode. Stop In Stop mode, most peripheral clocks are disabled and placed in a static state. Stop mode retains all registers and SRAMs while maintaining Low Voltage Detection protection. In Stop mode, the ADC, DAC, CMP, LPTMR, RTC, and pin interrupts are operational. The NVIC is disabled, but the AWIC can be used to wake up from an interrupt. Very Low Power Stop In VLPS mode, the contents of the SRAM are retained. The CMP (low speed), ADC, OSC, RTC, LPTMR, LPIT, FlexIO, LPUART, LPI2C,LPSPI, and DMA are operational, LVD and NVIC are disabled, AWIC is used to wake up from interrupt. NOTE When the MCU is in HSRUN or VLP mode, user cannot write FlexRAM (EEPROM), and cannot launch an FTFE command including flash programming/erasing. 2.1.9 Debug controller This device has extensive debug capabilities including run control and tracing capabilities. The standard ARM debug port supports SWD/JTAG interface.

NOTE: The likelihood of permanent chip failure increases rapidly as soon as a characteristic begins to exceed one of its operating ratings. Operating requirement A specified value or range of values for a technical characteristic that you must guarantee during operation to avoid incorrect operation and possibly decreasing the useful life of the chip Operating behavior A specified value or range of values for a technical characteristic that are guaranteed during operation if you meet the operating requirements and any other specified conditions Typical value A specified value for a technical characteristic that: • Lies within the range of values specified by the operating behavior • Is representative of that characteristic during operation when you meet the typical-value conditions or other specified conditions NOTE: Typical values are provided as design guidelines and are neither tested nor guaranteed. 42 NXP Semiconductors Kinetis KE1xF with up to 512 KB Flash, Rev. 4, 06/2019 Electrical characteristics 5.1.2 Examples EX AM PL E Operating rating: EX AM PL E Operating requirement: EX AM PL E Operating behavior that includes a typical value: 5.1.3 Typical-value conditions Typical values assume you meet the following conditions (or other conditions as specified): Symbol Description Value Unit TA Ambient temperature 25 °C VDD Supply voltage 5.0 V Kinetis KE1xF with up to 512 KB Flash, Rev. 4, 06/2019 43 NXP Semiconductors Electrical characteristics 5.1.4 Relationship between ratings and operating requirements O a gr tin ra pe g tin ( ) in.

Thermal characterization parameter indicating the temperature difference between package top and the junction temperature per JEDEC JESD51-2. 5.3.3.2.4 General notes for specifications at maximum junction temperature An estimation of the chip junction temperature, TJ, can be obtained from this equation: TJ = TA + (RθJA × PD) where: • TA = ambient temperature for the package (°C) • RθJA = junction to ambient thermal resistance (°C/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. Unfortunately, there are two values in common usage: the value determined on a single layer board and the value obtained on a board with two planes. For packages such as the PBGA, these values can be different by a factor of two. Which value is closer to the application depends on the power dissipated by other components on the board. The value obtained on a single layer board is appropriate for the tightly packed printed circuit board. The value obtained on the board with the internal planes is usually appropriate if the board has low power dissipation and the components are well separated. 62 NXP Semiconductors Kinetis KE1xF with up to 512 KB Flash, Rev. 4, 06/2019 Electrical characteristics When a heat sink is used, the thermal resistance is expressed in the following equation as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance: RθJA = RθJC + RθCA where: • RθJA = junction to ambient thermal resistance (°C/W) • RθJC = junction to case thermal resistance (°C/W) • RθCA = case to ambient thermal resistance (°C/W) RθJC is device related and cannot be influenced by the user. The user controls the thermal environment to change the case to ambient thermal resistance, RθCA. For instance, the user can change the size of the heat sink, the air flow around the device, the interface material, the mounting arrangement on printed circuit board, or change the thermal dissipation on the printed circuit board surrounding the device. To determine the junction temperature of the device in the application when heat sinks are not used, the Thermal Characterization Parameter (ΨJT) can be used to determine the junction temperature with a measurement of the temperature at the top center of the package case using this equation: TJ = TT + (ΨJT × PD) where: • TT = thermocouple temperature on top of the package (°C) • ΨJT = thermal characterization parameter (°C/W) • PD = power dissipation in the package (W) 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.

However, take normal precautions to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. 90 NXP Semiconductors Kinetis KE1xF with up to 512 KB Flash, Rev. 4, 06/2019 Design considerations 6.1.1 Printed circuit board recommendations • Place connectors or cables on one edge of the board and do not place digital circuits between connectors. • Drivers and filters for I/O functions must be placed as close to the connectors as possible. Connect TVS devices at the connector to a good ground. Connect filter capacitors at the connector to a good ground. Consider to add ferrite bead or inductor to some sensitive lines. • Physically isolate analog circuits from digital circuits if possible. • Place input filter capacitors as close to the MCU as possible. • For best EMC performance, route signals as transmission lines; use a ground plane directly under LQFP packages; and solder the exposed pad (EP) to ground directly under QFN packages. 6.1.2 Power delivery system Consider the following items in the power delivery system: • Use a plane for ground. • Use a plane for MCU VDD supply if possible. • Always route ground first, as a plane or continuous surface, and never as sequential segments. • Always route the power net as star topology, and make each power trace loop as minimum as possible. • Route power next, as a plane or traces that are parallel to ground traces. • Place bulk capacitance, 10 μF or more, at the entrance of the power plane. • Place bypass capacitors for MCU power domain as close as possible to each VDD/VSS pair, including VDDA/VSSA and VREFH/VREFL. • The minimum bypass requirement is to place 0.1 μF capacitors positioned as near as possible to the package supply pins. 6.1.3 Analog design Each ADC input must have an RC filter as shown in the following figure. The maximum value of R must be RAS max if fast sampling and high resolution are required. The value of C must be chosen to ensure that the RC time constant is very small compared to the sample period.

This disables the digital input path to the MCU. 6.1.5 Crystal oscillator When using an external crystal or ceramic resonator as the frequency reference for the MCU clock system, refer to the following table and diagrams. The feedback resistor, RF, is incorporated internally with the low power oscillators. An external feedback is required when using high gain (HGO=1) mode. The series resistor, RS, is required in high gain (HGO=1) mode when the crystal or resonator frequency is below 2 MHz. Otherwise, the low power oscillator (HGO=0) must not have any series resistance; and the high frequency, high gain oscillator with a 4 3 frequency above 2 MHz does not require any series resistance.
