NXP Semiconductors S9KEAZN8AMTG

Overview

S9KEAZN8AMTG 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 real-time control in engine management, body electronics, and sensor interface modules requiring extended temperature support.

For engineers reviewing the S9KEAZN8AMTG datasheet, S9KEAZN8AMTG pinout, S9KEAZN8AMTG application, or S9KEAZN8AMTG equivalent, this page delivers verified package mapping (16-pin TSSOP), confirmed -40°C to +125°C ambient operation, validated low-power Stop mode current (≤110 µA at 5 V), and documented peripheral compatibility including UART, I²C, SPI, 12-bit ADC, and FlexTimer/PWM modules.

Technical Context

The S9KEAZN8AMTG implements a single-cycle 32-bit x 32-bit multiplier and single-cycle I/O access port for deterministic real-time execution. Its clock system integrates an internal 37.5 kHz factory-trimmed reference enabling 48 MHz system clock generation via FLL, plus external crystal support (32.768 kHz or 4–24 MHz) with selectable low-power/high-gain oscillator modes.

Power management includes three operational modes (Run, Wait, Stop), low-voltage detection with configurable trip points (2.56–4.4 V), and Stop-mode current adders quantified for ADC (86 µA), LVD (130 µA), and RTC (<1 µA). The device features aliased SRAM bitbanding and BME for atomic bit manipulation - critical for automotive fault-handling logic.

FAQ

What is the maximum operating frequency of the S9KEAZN8AMTG?

The S9KEAZN8AMTG operates at up to 48 MHz using its ARM Cortex-M0+ core. This frequency is achieved via the internal FLL locked to either the 37.5 kHz factory-trimmed internal reference or an external crystal/resonator (4–24 MHz). The bus frequency runs at half the core speed (24 MHz), and all timing specifications in the datasheet are validated at this maximum rate. The S9KEAZN8AMTG maintains full peripheral functionality and timing compliance at 48 MHz across its full –40°C to +125°C temperature range.

Does the S9KEAZN8AMTG support debugging during development?

Yes, the S9KEAZN8AMTG includes a Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards. It uses two dedicated pins (SWD_CLK and SWD_DIO) for full-featured debugging - including flash programming, real-time variable inspection, hardware breakpoints, and trace. The SWD interface operates across the full voltage range (2.7–5.5 V) and supports clock frequencies up to 24 MHz, enabling rapid firmware iteration. No additional debug probe is required beyond standard ARM-compliant tools such as LPC-Link2 or SEGGER J-Link.

What package type does the S9KEAZN8AMTG use?

The S9KEAZN8AMTG is packaged in a 16-pin TSSOP (Thin Shrink Small Outline Package) measuring 4.5 mm × 5 mm, with lead-free finish and moisture sensitivity level 3 (MSL3). This package is explicitly confirmed in the KEA8 Sub-Family Data Sheet (S9KEA8P44M48SF0, Rev. 5) for the "MTG" suffix variant. It offers a compact footprint ideal for space-constrained automotive modules and is compatible with standard surface-mount assembly processes including reflow up to 260°C.

Can the S9KEAZN8AMTG operate without an external crystal?

Yes, the S9KEAZN8AMTG can operate without an external crystal. Its Internal Clock Source (ICS) includes a factory-trimmed 37.5 kHz internal reference oscillator that feeds the FLL to generate a stable 48 MHz system clock. This configuration eliminates external timing components, reducing BOM cost and board area. Startup time is ≤50 µs, and frequency accuracy is ±0.8% over temperature - sufficient for non-precision timing applications. External crystals remain optional for higher accuracy or RTC calibration.

Is the S9KEAZN8AMTG qualified for automotive use?

Yes, the S9KEAZN8AMTG is automotive-qualified per AEC-Q100 Grade 1 (–40°C to +125°C ambient), as indicated by the "S" prefix and "M" temperature code in its part number. It meets automotive reliability requirements including thermal cycling, humidity testing, and ESD robustness (±6 kV HBM). The device includes functional safety features such as low-voltage detection with interrupt/reset, CRC hardware, watchdog timer with independent clock source, and programmable memory protection - making it suitable for ASIL-B–capable systems when implemented per ISO 26262 guidelines.
