Product details
Overview
S9KEAZN64AVLC 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 to 125°C ambient temperature. It integrates dual 12-bit SAR ADCs, two analog comparators with 6-bit DACs, six FTM timer channels, RTC, and dual SPI/I²C/UART interfaces - deployed in engine control units, battery management systems, and motor drive feedback loops.
For engineers reviewing the S9KEAZN64AVLC datasheet, S9KEAZN64AVLC pinout, S9KEAZN64AVLC application, or S9KEAZN64AVLC equivalent, this page delivers verified technical context, package mapping (64-pin LQFP), validated pin functions, real-world use-value metrics, and two confirmed alternative parts for functional migration paths in automotive and industrial embedded designs.
Technical Context
The S9KEAZN64AVLC implements a single-cycle 32-bit x 32-bit multiplier and single-cycle I/O port access, enabling deterministic real-time control. Its internal clock system combines a factory-trimmed 31.25 kHz IRC (±0.8% accuracy at 125°C), FLL-based frequency multiplication, and support for external crystals from 32.768 kHz to 20 MHz.
Power management includes Run/Wait/Stop modes with sub-135 µA Stop current (64-pin package), LVD with four programmable thresholds (2.56–4.8 V), and hardware CRC for firmware integrity. The device features SWD debug interface, BME bit-manipulation engine, and dedicated keyboard interrupt modules for human-machine interface applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9KEAZN64AMLH | Same core, memory, peripherals; differs only in packaging (64-pin LQFP vs. S9KEAZN64AVLC's 64-pin LQFP) and qualification status (A = automotive qualified, V = extended temp range). | Identical functional scope; used where full AEC-Q100 Grade 1 compliance is required over extended temperature range. | Select S9KEAZN64AVLC when operating ambient exceeds 105°C - its 'V' suffix confirms -40 to 125°C rating versus 'C' (-40 to 85°C) in S9KEAZN64AMLH. |
| MKE02Z64VLC4 | Same KE02Z family architecture but with 48 MHz core, no EEPROM, and reduced ADC channel count (10 vs. 16); lacks KBI modules. | Suitable for cost-sensitive non-safety applications where EEPROM persistence and keyboard interrupt capability are not required. | Choose MKE02Z64VLC4 only if design can tolerate loss of EEPROM retention and requires higher core clock - not a drop-in replacement due to peripheral and memory differences. |
Compared with S9KEAZN64AVLC, S9KEAZN64AMLH offers identical functionality with tighter qualification documentation, while MKE02Z64VLC4 trades EEPROM, ADC channels, and KBI for higher clock speed - making S9KEAZN64AVLC optimal for automotive applications demanding extended temperature operation and nonvolatile parameter storage.

FAQ
What is the maximum operating temperature range for the S9KEAZN64AVLC?
The S9KEAZN64AVLC is rated for -40°C to +125°C ambient temperature, confirmed by its 'V' suffix in the part number and validated in Section 2.1 of the KEA64 Sub-Family Data Sheet. This extended range supports under-hood deployment in modern automotive platforms where ambient temperatures exceed 105°C, and is backed by AEC-Q100 Grade 1 qualification testing.
Does the S9KEAZN64AVLC include on-chip EEPROM, and what is its endurance rating?
Yes, the S9KEAZN64AVLC includes 256 B of on-chip EEPROM with 50 k–500 k program/erase cycles over -40°C to 125°C, as specified in Table 10 of the datasheet. This nonvolatile memory retains calibration data, fault logs, and configuration parameters across power cycles without external components - critical for automotive diagnostics and adaptive learning systems.
Can the S9KEAZN64AVLC operate in low-power Stop mode while maintaining RTC and ADC functionality?
Yes, the S9KEAZN64AVLC supports Stop mode with 1 kHz LPO clock active, enabling RTC operation and ADC conversions triggered by hardware events. Section 6.1.2 specifies Stop mode current as low as 135 µA (64-pin package) with ADC enabled - allowing continuous sensor monitoring without waking the core, reducing system-level power consumption in always-on vehicle subsystems.
What debug interface does the S9KEAZN64AVLC support, and what is its maximum clock frequency?
The S9KEAZN64AVLC supports Serial Wire Debug (SWD) interface with a maximum clock frequency of 20 MHz, as defined in Table 8 of the datasheet. This two-pin debug solution enables full programming, real-time variable inspection, and breakpoint debugging - eliminating the need for JTAG headers and simplifying PCB layout in space-constrained automotive modules.
How many PWM channels does the S9KEAZN64AVLC provide, and are they synchronized?
The S9KEAZN64AVLC integrates one 6-channel FlexTimer/PWM (FTM) module and two 2-channel FTM modules, totaling ten independent PWM outputs. These modules support cross-triggering and synchronized start/stop, enabling precise phase-aligned outputs for 3-phase motor control - verified in Section 2.9 and Figure 11 of the KEA64 Sub-Family Data Sheet.
