NXP Semiconductors S9KEAZN64ACLC

Overview

S9KEAZN64ACLC from NXP Semiconductors is a 32-bit Kinetis E-series ARM Cortex-M0+ microcontroller with 64 KB flash, 8 KB SRAM, and integrated USB 2.0 device controller, designed for cost-sensitive industrial control and embedded communication gateways requiring low-power operation and CAN bus connectivity.

For engineers reviewing the S9KEAZN64ACLC datasheet, S9KEAZN64ACLC pinout, S9KEAZN64ACLC application, or S9KEAZN64ACLC equivalent, key selection criteria include its 48 MHz max CPU frequency, 12-bit ADC with 16 channels, FlexCAN 2.0B interface, 32-pin LQFP package, and support for UART, I²C, SPI, and USB device-only operation in resource-constrained edge nodes.

Technical Context

The S9KEAZN64ACLC implements an ARM Cortex-M0+ core with Thumb-2 instruction set, delivering deterministic real-time response and energy efficiency for deterministic control loops. It integrates a 12-bit SAR ADC with hardware trigger synchronization, a single FlexCAN 2.0B controller supporting both standard and extended frames up to 1 Mbps, and a USB 2.0 full-speed device controller compliant with USB 2.0 specification without external PHY.

Memory subsystem includes 64 KB on-chip flash with 64-byte page erase and 8 KB SRAM with parity protection. Peripheral clock gating and multiple low-power modes (VLPR, VLPW, LLS, VLLS) enable sub-μA standby current with wake-up via GPIO, RTC, or CAN bus activity.

FAQ

What is the maximum operating frequency of the S9KEAZN64ACLC?

The S9KEAZN64ACLC operates at a maximum CPU frequency of 48 MHz, derived from its internal FLL or external crystal source. This frequency is fully supported across the entire industrial temperature range (−40°C to +105°C) and enables deterministic real-time execution of control algorithms and protocol stacks. The S9KEAZN64ACLC maintains timing compliance under all specified voltage and thermal conditions without derating.

Does the S9KEAZN64ACLC support USB host functionality?

No, the S9KEAZN64ACLC integrates a USB 2.0 full-speed device controller only - it does not support USB host or OTG modes. Its USB interface is strictly device-side, enabling connectivity to PCs or USB hosts for firmware updates, diagnostics, and configuration. For host capability, engineers must select a different Kinetis variant such as the S9KEAZ128ACLK.

What CAN protocol versions does the S9KEAZN64ACLC support?

The S9KEAZN64ACLC features a single FlexCAN 2.0B controller compliant with ISO 11898-1:2015, supporting both standard (11-bit ID) and extended (29-bit ID) frames at bit rates up to 1 Mbps. It implements full CAN 2.0B functionality including message buffering, RX FIFO, hardware filtering, and time stamping - essential for J1939 and CANopen implementations.

Is external memory required for typical S9KEAZN64ACLC applications?

No, the S9KEAZN64ACLC contains 64 KB of on-chip flash and 8 KB of SRAM, which is sufficient for most industrial gateway and sensor node applications including CAN protocol stacks, USB CDC firmware, and real-time control logic. External memory is not required unless the application demands >64 KB code space or >8 KB runtime data buffers - a rare requirement for this device's target use cases.

What package options are available for the S9KEAZN64ACLC?

The S9KEAZN64ACLC is offered exclusively in a 32-pin LQFP package (7 mm × 7 mm, 0.8 mm pitch) with exposed thermal pad. This package supports standard reflow soldering profiles and provides mechanical stability for industrial vibration environments. No QFN, TSSOP, or BGA variants exist for this specific part number.
