Product details
Overview
S9KEAZ128ACLHR from NXP Semiconductors is an automotive-qualified Arm® Cortex-M0+ microcontroller with 128 KB flash, 16 KB RAM, and operation up to 48 MHz - designed for real-time control in engine management, body electronics, and powertrain subsystems.
For engineers reviewing the S9KEAZ128ACLHR datasheet, S9KEAZ128ACLHR pinout, S9KEAZ128ACLHR application, or S9KEAZ128ACLHR equivalent, this page delivers verified electrical specs, package mapping (64-pin LQFP), validated peripheral timing, confirmed CAN interface support, and two documented alternative parts for functional substitution in industrial and automotive embedded designs.
Technical Context
The S9KEAZ128ACLHR integrates a factory-trimmed 37.5 kHz internal reference enabling 48 MHz system clock generation via its FLL-based ICS module, with selectable low-power or high-gain oscillator modes for external crystals (32.768 kHz or 4–24 MHz). Its MSCAN module implements ISO 11898-1 compliant CAN 2.0B protocol with programmable bit timing and automatic retransmission.
It supports Stop mode with sub-2 µA current (VDD = 3 V, –40 to 125 °C), retaining RTC, ADC, ACMP, and LVD functionality - enabled by dedicated 1 kHz LPO and configurable wake-up sources including KBI, IRQ, and analog comparators with 6-bit DAC references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm® Cortex-M0+, 48 MHz max - enables deterministic real-time response for motor control and sensor fusion tasks. |
| Flash / RAM | 128 KB flash (programmable at 2.7–5.5 V), 16 KB SRAM - sufficient for AUTOSAR-compliant bootloaders and safety-critical application code. |
| Operating Voltage | 2.7–5.5 V - compatible with 12 V automotive battery systems after regulation, supporting cold-crank (down to 2.7 V) and load-dump transients. |
| Temperature Range | –40 to 125 °C ambient - qualified per AEC-Q100 Grade 1, suitable for under-hood and transmission control units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9KEAZ128AMLHR | Same core, memory, and peripherals but rated for –40 to 105 °C (V-grade) instead of –40 to 125 °C (M-grade); no CAN module. | Suitable for cabin electronics or non-under-hood modules where extended temperature range and CAN are not required. | Select S9KEAZ128AMLHR only if M-grade thermal margin and MSCAN are unnecessary - reduces cost and qualification scope. |
| MKE02Z64VQH2 | Same Kinetis KE02 family, 64 KB flash, 8 KB RAM, 40 MHz max, no MSCAN, different pinout (64-pin QFP vs. LQFP). | Targeted at cost-sensitive entry-level automotive modules with simpler communication needs (UART/I²C only). | Choose MKE02Z64VQH2 when CAN is omitted and flash/RAM requirements are halved - verify PCB layout compatibility due to package variant. |
Compared with S9KEAZ128ACLHR, S9KEAZ128AMLHR removes CAN and reduces temperature rating - trading capability for cost in less demanding environments; MKE02Z64VQH2 offers lower integration and memory but requires board redesign due to incompatible footprint and missing CAN.

FAQ
What is the maximum operating frequency of the S9KEAZ128ACLHR?
The S9KEAZ128ACLHR operates at up to 48 MHz system clock frequency, derived from its internal FLL using either the factory-trimmed 37.5 kHz IRC or an external crystal/resonator. This frequency is fully supported across the full –40 to 125 °C temperature range and 2.7–5.5 V supply voltage, enabling deterministic real-time execution for automotive control loops.
Does the S9KEAZ128ACLHR include a CAN controller?
Yes, the S9KEAZ128ACLHR integrates an MSCAN module compliant with ISO 11898-1 (CAN 2.0B), supporting both standard and extended message formats, programmable bit timing, and automatic retransmission. The presence of CANH/CANL pins in its 64-pin LQFP package confirms native differential bus interface capability.
What is the temperature grade of the S9KEAZ128ACLHR?
The S9KEAZ128ACLHR is rated for –40 to 125 °C ambient operation and qualified to AEC-Q100 Grade 1. The 'M' in its part number (S9KEAZ128ACLHR → T-field = M) explicitly denotes the 125 °C maximum junction temperature rating, making it suitable for under-hood applications including engine and transmission control.
How much SRAM and flash memory does the S9KEAZ128ACLHR have?
The S9KEAZ128ACLHR contains 128 KB of on-chip flash memory and 16 KB of SRAM. Flash is rated for 100,000 program/erase cycles and supports in-application programming (IAP) at 2.7–5.5 V; SRAM includes bit-band aliasing for atomic peripheral bit manipulation - both resources are accessible across the full operating temperature and voltage range.
What low-power modes does the S9KEAZ128ACLHR support?
The S9KEAZ128ACLHR supports Run, Wait, and Stop modes. In Stop mode, it achieves ≤2 µA typical current (VDD = 3 V, –40 to 125 °C) while retaining RTC, ADC, ACMP, and LVD functionality via its 1 kHz LPO clock - enabling always-on monitoring without CPU intervention in battery-sensitive automotive subsystems.
