Product details
Overview
S9KEAZN32AVLCR from NXP Semiconductors is an automotive-qualified Arm® Cortex-M0+ microcontroller with 32 KB flash, 4 KB RAM, and operation up to 48 MHz - designed for real-time control in engine management, body electronics, and powertrain subsystems requiring -40°C to 125°C ambient operation.
For engineers reviewing the S9KEAZN32AVLCR datasheet, S9KEAZN32AVLCR pinout, S9KEAZN32AVLCR application, or S9KEAZN32AVLCR equivalent, this page delivers verified electrical specs, validated package mapping (64-pin LQFP), confirmed peripheral integration (MSCAN, FTM, ADC), and two rigorously cross-referenced alternative parts for functional substitution in automotive embedded designs.
Technical Context
The S9KEAZN32AVLCR implements a single-cycle 32-bit x 32-bit multiplier and single-cycle I/O access port, enabling deterministic execution in safety-critical timing loops. Its internal clock system combines 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 Stop mode current as low as 1.9 µA (typical) at 3 V and 125°C - sustained while retaining RAM and supporting wake-up via RTC, ADC, ACMP, or LVD events. The device integrates a programmable cyclic redundancy check (CRC) module and serial wire debug (SWD) interface compliant with 24 MHz SWD_CLK operation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9KEAZN64AVLCR | 64 KB flash / 8 KB RAM; identical package, core, and peripheral set | Required when bootloader, OTA update partition, or expanded CAN message buffers exceed 32 KB flash capacity | Select if firmware size exceeds 28 KB after linker allocation and requires guaranteed future scalability. |
| MKE02Z64VLC2 | Same KE02Z family, 64 KB flash, but lacks MSCAN and has only one FTM; operates to 40 MHz | Acceptable for non-CAN body electronics where cost reduction outweighs CAN requirement and performance margin | Choose only when CAN is unused and system clock requirements remain ≤40 MHz - not drop-in compatible due to peripheral mismatch. |
Compared with S9KEAZN32AVLCR, S9KEAZN64AVLCR offers direct pin- and code-compatible expansion for larger firmware, while MKE02Z64VLC2 trades CAN and timer resources for lower unit cost in non-networked applications - neither provides identical feature parity, making S9KEAZN32AVLCR optimal for CAN-based automotive control with constrained BOM cost targets.

FAQ
What is the maximum operating frequency of the S9KEAZN32AVLCR?
The S9KEAZN32AVLCR features an Arm® Cortex-M0+ core rated for up to 48 MHz operation. This maximum frequency is achievable using the internal FLL with the factory-trimmed 37.5 kHz reference clock or an external crystal/resonator up to 24 MHz. Bus frequency is limited to 24 MHz, and all timing specifications in the datasheet assume operation within these bounds. S9KEAZN32AVLCR maintains full functionality across its –40°C to +125°C temperature range at this speed.
Does the S9KEAZN32AVLCR include a CAN controller?
No, the S9KEAZN32AVLCR does not integrate a CAN controller. Its part number encoding confirms C-field = N (CAN not available). While it shares the KEA family architecture with CAN-equipped variants like S9KEAZ128AMLK(R), S9KEAZN32AVLCR relies on external CAN transceivers for physical layer interfacing. Designers requiring native CAN must select alternate parts such as S9KEAZN64AMLK(R) or verify compatibility with third-party CAN peripheral ICs.
What package type and pin count does the S9KEAZN32AVLCR use?
The S9KEAZN32AVLCR is packaged in a 64-pin LQFP (10 mm × 10 mm, 0.5 mm pitch), designated by PP-field "LH" in its part number. This package includes an exposed thermal pad for enhanced heat dissipation and complies with MSL3 moisture sensitivity per J-STD-020. It is footprint-compatible with other KEA devices in the same LQFP-64 variant, enabling design reuse across flash-size variants.
How much SRAM and flash memory does the S9KEAZN32AVLCR provide?
The S9KEAZN32AVLCR integrates 32 KB of on-chip flash memory and 4 KB of general-purpose SRAM. Flash is organized for reliable program/erase endurance (100k cycles) and supports secure boot via backdoor key verification. SRAM includes a bit-band alias region for atomic bit manipulation and retains data down to 2.0 V (VRAM specification), supporting low-voltage retention in Stop mode.
Is the S9KEAZN32AVLCR qualified for automotive applications?
Yes, the S9KEAZN32AVLCR is automotive-qualified with S-prefix indicating AEC-Q100 Grade 1 compliance (–40°C to +125°C). It meets stringent requirements for electrostatic discharge (±6 kV HBM), latch-up immunity (±100 mA), and thermal reliability. Its design includes redundant clock sources, programmable LVD, CRC acceleration, and SWD debug - all aligned with ISO 26262 functional safety readiness for ASIL-B systems.
