Product details
Overview
S9KEAZN64AMLC from NXP Semiconductors is an automotive-qualified Arm® Cortex-M0+ microcontroller with 64 KB flash, 4 KB RAM, and 256 B EEPROM, operating at up to 40 MHz core clock and -40°C to +125°C ambient temperature. It integrates dual FlexTimer/PWM modules, a 12-bit SAR ADC with Stop-mode operation, two analog comparators with 6-bit DACs, and supports UART, SPI, and I²C for motor control and body electronics applications.
For engineers reviewing the S9KEAZN64AMLC datasheet, S9KEAZN64AMLC pinout, S9KEAZN64AMLC application, or S9KEAZN64AMLC equivalent, this page delivers verified electrical specs, package mapping, thermal performance data, low-power mode current consumption (as low as 135 µA in Stop), and confirmed alternative parts for automotive-grade embedded design validation and sourcing.
Technical Context
The S9KEAZN64AMLC implements an Arm Cortex-M0+ core with single-cycle 32×32-bit multiplier and single-cycle I/O access, paired with an integrated Internal Clock Source (ICS) featuring FLL and factory-trimmed 31.25 kHz internal reference for stable 40 MHz system clock generation. Its power management includes Run, Wait, and Stop modes with LVD interrupt/reset and programmable trip points across high/low voltage ranges.
Peripherals include three UARTs, two SPIs, one I²C, six-channel and two dual-channel FlexTimer/PWM units, RTC, CRC engine, and SWD debug interface. Analog subsystem comprises a 16-channel 12-bit SAR ADC with hardware trigger support and two ACMPs each with 6-bit DAC and programmable reference input - all functional in Stop mode with sub-µA adders.

FAQ
What is the maximum operating frequency of the S9KEAZN64AMLC core?
The S9KEAZN64AMLC features an Arm Cortex-M0+ core rated for up to 40 MHz system and core clock frequency, with bus clock support up to 20 MHz. This performance level is achieved using the internal FLL with either external crystal (4–20 MHz) or factory-trimmed internal reference, enabling deterministic real-time execution for automotive control loops. The S9KEAZN64AMLC maintains this speed across its full -40°C to +125°C operating range.
Does the S9KEAZN64AMLC support debugging via SWD?
Yes, the S9KEAZN64AMLC includes a Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards, supporting full flash programming, real-time register inspection, and breakpoint debugging using standard tools like SEGGER J-Link or NXP LPC-Link2. SWD operates at up to 20 MHz and requires only two pins (SWD_DIO and SWD_CLK), preserving GPIO resources. The S9KEAZN64AMLC implements SWD electricals across its full 2.7–5.5 V supply range.
What are the low-power capabilities of the S9KEAZN64AMLC?
The S9KEAZN64AMLC supports three power modes: Run, Wait, and Stop. In Stop mode with only the 1 kHz LPO clock active, it draws just 135 µA (64-pin package) - and as low as 41 µA with ADC disabled. Critical analog modules (ADC, ACMP, LVD) remain operational in Stop mode with minimal current adders (e.g., 82 µA for ADC). The S9KEAZN64AMLC achieves this via clock gating, voltage regulator optimization, and selective peripheral retention - essential for battery-backed automotive modules.
Is the S9KEAZN64AMLC automotive-qualified?
Yes, the S9KEAZN64AMLC is automotive-qualified per AEC-Q100 Grade 1 (-40°C to +125°C) and manufactured in NXP's IATF 16949-certified facilities. Its part number prefix "S" confirms automotive qualification, and it includes features required for automotive use: extended temperature operation, enhanced ESD robustness (±6 kV HBM), latch-up immunity (±100 mA), and built-in diagnostics including CRC engine and programmable LVD. The S9KEAZN64AMLC is designed for deployment in engine, transmission, and chassis control systems.
What communication interfaces does the S9KEAZN64AMLC integrate?
The S9KEAZN64AMLC integrates two SPI modules, up to three UART modules (including LIN-capable UART0), and one I²C module - all accessible via multiplexed GPIO pins. These interfaces support daisy-chained sensor networks, diagnostic communication (ISO 9141/KWP2000), and inter-ECU messaging. UART0 supports automatic LIN break detection and sync field generation, while SPI supports master/slave modes with configurable frame format. The S9KEAZN64AMLC routes all interfaces to pins with configurable drive strength and programmable pullups for robust noise immunity.
