Product details
Overview
S9KEAZN64AMLH 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, 12-bit SAR ADC with Stop-mode operation, two analog comparators with 6-bit DACs, and supports UART, SPI, and I²C interfaces for embedded control in engine management and body electronics.
For engineers reviewing the S9KEAZN64AMLH datasheet, S9KEAZN64AMLH pinout, S9KEAZN64AMLH application, or S9KEAZN64AMLH equivalent, this page delivers verified technical context, package-specific electrical behavior, real-world use scenarios, and validated alternative options - all grounded in the official KEA64 Sub-Family Data Sheet Rev. 8 (July 2026).
Technical Context
The S9KEAZN64AMLH implements a single-cycle 32-bit x 32-bit multiplier and single-cycle I/O access port, enabling deterministic real-time control. Its internal clock system combines a factory-trimmed 31.25 kHz IRC (±0.8% at 125°C), FLL-based frequency synthesis, and support for external crystals from 32.768 kHz to 20 MHz with selectable low-power or high-gain oscillator modes.
Power management includes Run, Wait, and Stop modes with sub-135 µA Stop current (64-pin package), LVD with four programmable warning thresholds, and CRC and SWD debug support. The device features 57 GPIOs, two 8-bit keyboard interrupt modules, and a bit manipulation engine (BME) for efficient register-level control.

FAQ
What is the maximum operating frequency of the S9KEAZN64AMLH core and bus clocks?
The S9KEAZN64AMLH features an Arm® Cortex-M0+ core rated for up to 40 MHz system clock and up to 20 MHz bus clock. These frequencies are supported across the full -40°C to +125°C operating temperature range and 2.7 V to 5.5 V supply voltage, as confirmed in Section 2.2 of the KEA64 Sub-Family Data Sheet Rev. 8. The S9KEAZN64AMLH achieves this performance using its internal FLL with factory-trimmed IRC reference.
Does the S9KEAZN64AMLH support debugging during development?
Yes, the S9KEAZN64AMLH includes a Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards. It supports full programming, erasing, and real-time debugging at up to 20 MHz SWD_CLK frequency, with setup/hold timing validated down to 10 ns. This capability is documented in Section 7.1.1 of the KEA64 Sub-Family Data Sheet Rev. 8 and requires only two pins (SWD_DIO and SWD_CLK) for complete debug access to the S9KEAZN64AMLH.
What is the flash endurance specification for the S9KEAZN64AMLH?
The S9KEAZN64AMLH guarantees a minimum of 10,000 program/erase cycles for its 64 KB flash memory over the full -40°C to +125°C operating temperature range, with typical endurance reaching 100,000 cycles. This specification is explicitly stated in Table 10 of the KEA64 Sub-Family Data Sheet Rev. 8 and applies to both block and sector erase operations used during field firmware updates of the S9KEAZN64AMLH.
Can the S9KEAZN64AMLH operate in low-power Stop mode while retaining analog functionality?
Yes, the S9KEAZN64AMLH supports Stop mode with ADC, analog comparators (ACMP), and low-voltage detection (LVD) active. In this mode, typical current consumption is 135 µA for the 64-pin package at 3 V, as specified in Table 4 of the KEA64 Sub-Family Data Sheet Rev. 8. The ADC can be triggered by hardware events and operate without CPU intervention, making it ideal for continuous sensor monitoring in battery-powered vehicle subsystems using the S9KEAZN64AMLH.
What package type and pin count does the S9KEAZN64AMLH use?
The S9KEAZN64AMLH uses a 64-pin LQFP package measuring 10 mm × 10 mm, as confirmed in Section 2.11 and Section 4.3 of the KEA64 Sub-Family Data Sheet Rev. 8. The "LH" suffix in the part number explicitly denotes this 64-pin LQFP variant, distinguishing it from the 32-pin "LC" option. Thermal resistance is characterized at 53°C/W (junction-to-ambient) on a 4-layer PCB, ensuring predictable thermal performance in automotive applications using the S9KEAZN64AMLH.
