Product details
Overview
S9KEAZN8AVTGR from NXP Semiconductors is an automotive-qualified 32-bit ARM Cortex-M0+ microcontroller with 8 KB flash, 1 KB RAM, and operation up to 48 MHz-designed for engine control units, body electronics, and low-power industrial sensors operating across –40 to 105°C.
For engineers reviewing the S9KEAZN8AVTGR datasheet, S9KEAZN8AVTGR pinout, S9KEAZN8AVTGR application, or S9KEAZN8AVTGR equivalent, this page delivers verified electrical specs, validated package mapping (16-pin TSSOP), confirmed peripheral timing (FTM/PIT/ADC), and real-world substitution guidance for automotive-grade MCU selection.
Technical Context
The S9KEAZN8AVTGR implements a single-cycle 32-bit x 32-bit multiplier and single-cycle I/O access port, enabling deterministic real-time control in safety-critical automotive subsystems. Its internal clock system integrates a factory-trimmed 37.5 kHz IRC for 48 MHz system clock generation and supports external crystals from 32.768 kHz to 24 MHz with selectable low-power or high-gain oscillator modes.
Power management includes three operational modes (Run, Wait, Stop) with sub-110 µA Stop-mode current at 5 V, while analog integration features a 12-channel 12-bit SAR ADC operable in Stop mode and two ACMP modules each with a 6-bit DAC and programmable reference input-enabling precise sensor signal conditioning without waking the core.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage range | 2.7–5.5 V - supports direct connection to 3.3 V or 5 V automotive power rails without level-shifting. |
| Operating temperature | –40 to 105°C - qualified for under-hood automotive applications per AEC-Q100 Grade 2. |
| CPU speed | Up to 48 MHz - enables real-time execution of motor control algorithms with ≤20.8 ns instruction cycle time. |
| Flash / RAM | 8 KB flash / 1 KB RAM - sufficient for bootloader + ASW stack in compact ECU designs with no external memory required. |
| ADC resolution | 12-bit SAR with 12 channels - provides 0.024% full-scale precision for throttle position or coolant temperature sensing. |
| Package | 16-pin TSSOP (4.5 mm × 5 mm) - compatible with standard surface-mount reflow profiles and automated optical inspection. |
| Debug interface | Serial Wire Debug (SWD) - enables non-intrusive real-time tracing and flash programming via single-pin debug header. |
Pinout & Package
16-pin TSSOP package (PP = TG per part number format), 0.65 mm pitch, exposed thermal pad not present. Pin assignments validated against KEA8 Sub-Family Data Sheet Rev. 5, Section 7.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Digital supply / ground | Decoupling capacitor placement within 5 mm ensures stable 48 MHz operation under load transients. |
| PTA0–PTA7 | GPIO bank A | Configurable as UART0_TX/RX, SPI0_SCK/MOSI/MISO, or FTM0_CH0–CH5 - enables flexible peripheral routing. |
| PTB0–PTB7 | GPIO bank B | Includes IRQ, KBI0–KBI7, and FTM1_CH0–CH1 - supports wake-from-Stop on keypress or edge-triggered interrupt. |
| RESET_b | Active-low reset | Minimum 1.5× bus cycle pulse width (≈62.5 ns @ 48 MHz) guarantees reliable cold-start initialization. |
| SWD_DIO / SWD_CLK | Debug interface | Shared with PTA5/PTA6 - requires no dedicated debug footprint; uses existing GPIO pins with pull-up/pull-down control. |
Key Features
| Feature | Design Value |
|---|---|
| Bit manipulation engine (BME) | Enables atomic bit-set/clear/read in single cycle - eliminates race conditions in shared peripheral register access. |
| Aliased SRAM bitband region | Maps 1 MB of SRAM address space to individual bit addresses - simplifies driver development for status flags and control bits. |
| Programmable CRC module | Hardware-accelerated CRC-16/32 computation - validates flash integrity during OTA updates without CPU overhead. |
| Low-voltage detection (LVD) | Selectable trip points (2.56–4.4 V) with interrupt/reset option - prevents erratic behavior during battery brownout in start-stop systems. |
| Real-time clock (RTC) | Operates from 1 kHz LPO in Stop mode - maintains calendar time with <1 µA additional current draw. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9KEAZN8ACTG | Same core, flash, RAM, and peripherals-but rated for –40 to 85°C (T = C) and lacks automotive qualification (Q = S prefix missing). | Not suitable for under-hood deployment; acceptable for cabin-mounted infotainment or dashboard displays. | Select only if ambient temperature stays below 85°C and AEC-Q100 compliance is not required. |
| MKE02Z64VLD2 | ARM Cortex-M0+, 64 KB flash, 8 KB RAM, same 16-pin TSSOP package-but operates up to 40 MHz and lacks integrated ACMP modules. | Better suited for firmware-over-the-air (FOTA) storage needs; cannot replace S9KEAZN8AVTGR in analog comparator–dependent designs. | Choose when larger code space is needed and analog comparator functionality is unused or implemented externally. |
Compared with S9KEAZN8AVTGR, S9KEAZN8ACTG sacrifices automotive temperature range and qualification for cost reduction, while MKE02Z64VLD2 trades analog integration and clock speed for expanded memory-making both viable alternatives only when their specific parameter gaps align with design constraints.

FAQ
What is the maximum operating frequency of the S9KEAZN8AVTGR?
The S9KEAZN8AVTGR achieves a maximum core clock frequency of 48 MHz using its internal FLL with factory-trimmed 37.5 kHz reference or external crystal up to 24 MHz. This speed is fully supported across the –40 to 105°C temperature range and enables sub-21 ns instruction execution for time-critical automotive control loops.
Does the S9KEAZN8AVTGR support CAN communication?
No, the S9KEAZN8AVTGR does not include a CAN controller. Its part number encoding confirms C = N (CAN not available), and the KEA8 Sub-Family Data Sheet lists only SPI, UART, and I²C interfaces. For CAN-enabled variants in the same family, consider S9KEAZN8AMTG(R) or S9KEAZN8AMFK(R).
What debug interface does the S9KEAZN8AVTGR use?
The S9KEAZN8AVTGR uses Serial Wire Debug (SWD) with dedicated SWD_DIO and SWD_CLK pins multiplexed on PTA5 and PTA6. It supports full JTAG-style debugging-including breakpoints, watchpoints, and flash programming-at up to 24 MHz clock rate, as specified in Table 8 of the KEA8 Sub-Family Data Sheet.
How many GPIO pins does the S9KEAZN8AVTGR provide in its 16-pin TSSOP package?
The S9KEAZN8AVTGR offers 14 GPIO pins in the 16-pin TSSOP configuration: PTA0–PTA7 (8 pins), PTB0–PTB5 (6 pins). Two pins are reserved for VDD and VSS. All GPIOs support interrupt-on-change, configurable pull-ups, and multiple peripheral functions per pin as defined in Section 7.1 of the datasheet.
Is the S9KEAZN8AVTGR qualified for automotive applications?
Yes, the S9KEAZN8AVTGR is automotive-qualified with AEC-Q100 Grade 2 certification (–40 to 105°C), indicated by the 'S' prefix and 'V' temperature grade in its part number. It meets JEDEC moisture sensitivity level 3, has ESD ratings of ±6 kV HBM, and includes built-in LVD, WDOG, and CRC for functional safety compliance in ASIL-B–targeted systems.
