NXP Semiconductors SPC5604CK0MLH6

Overview

SPC5604CK0MLH6 from NXP Semiconductors is a 32-bit automotive microcontroller based on the Power Architecture® e200z0h core, operating up to 64 MHz with 512 KB code flash, 64 KB data flash, and 48 KB SRAM - all featuring ECC protection. It integrates six FlexCAN modules, four LINFlex interfaces, three DSPI controllers, and a 10-bit ADC with 36 channels, targeting body control modules and gateway applications in 12 V automotive systems.

For engineers reviewing the SPC5604CK0MLH6 datasheet, SPC5604CK0MLH6 pinout, SPC5604CK0MLH6 application, or SPC5604CK0MLH6 equivalent, key selection criteria include its LQFP-144 package, FMPLL clock generation, Nexus 2+ debug interface, real-time counter with autonomous wakeup, and compliance with AUTOSAR timing requirements via STM and PIT timers.

Technical Context

The SPC5604CK0MLH6 implements a single-issue e200z0h CPU core with Variable Length Encoding (VLE) for reduced code footprint and operates at up to 64 MHz using its frequency-modulated PLL (FMPLL). Its crossbar switch enables concurrent access to flash, SRAM, and peripherals by multiple bus masters including eMIOS, FlexCAN, and DSPI.

It features a memory protection unit (MPU) with eight region descriptors, an interrupt controller (INTC) supporting 148 vectors, and boot assist via CAN or SCI. The device includes dedicated hardware blocks for AUTOSAR-compliant timing (STM, PIT), safety-critical monitoring (SWT, CMU), and system-level diagnostics (ECSM, WKPU with 18 wakeup sources).

Key Specifications

Pinout & Package

SPC5604CK0MLH6 is housed in a 144-pin LQFP package (20 × 20 × 1.4 mm) with exposed thermal pad.

FAQ

What is the maximum operating frequency of the SPC5604CK0MLH6?

The SPC5604CK0MLH6 operates at a maximum CPU frequency of 64 MHz, achieved via its integrated frequency-modulated phase-locked loop (FMPLL). This speed is specified under recommended operating conditions (ambient temperature up to 125 °C) and enables deterministic real-time execution for AUTOSAR-compliant body control applications. The FMPLL also supports spread-spectrum modulation to reduce electromagnetic interference in sensitive automotive environments.

Does the SPC5604CK0MLH6 support CAN FD?

No, the SPC5604CK0MLH6 does not support CAN FD. It integrates six FlexCAN modules compliant with ISO 11898-1 (Classical CAN 2.0B), supporting bit rates up to 1 Mbps. CAN FD capability was introduced in later-generation devices such as the SPC5605CK0MLH6. For SPC5604CK0MLH6, CAN message filtering, FIFO buffering, and mailbox-based transmission remain fully supported for legacy and mixed-network automotive architectures.

What debug interface does the SPC5604CK0MLH6 provide?

The SPC5604CK0MLH6 provides a Nexus 2+ development interface compliant with IEEE-ISTO 5001-2003 Class Two Plus standard. This interface supports real-time trace, non-intrusive breakpoints, data watchpoints, and calibrated timing - essential for ISO 26262 tool qualification and production calibration. It replaces JTAG as the primary debug path and is accessible via dedicated MDO/MCKO/EVTO pins in the 144 LQFP package.

How many ADC channels does the SPC5604CK0MLH6 have, and what is their resolution?

The SPC5604CK0MLH6 includes a 10-bit analog-to-digital converter with 36 input channels. This ADC supports programmable sample-and-hold timing, configurable conversion sequences, and cross-triggering with eMIOS or PIT timers via the CTU block. Its separate VDD_HV_ADC/VSS_HV_ADC supply domain ensures ±1 LSB integral nonlinearity (INL) performance across the full automotive temperature range (−40 °C to 125 °C).

Is the SPC5604CK0MLH6 pin-compatible with other MPC5604x variants?

Yes, the SPC5604CK0MLH6 is pin-compatible with all MPC5604B/C family members in the same 144 LQFP package, including MPC5604BK0MLH6 and MPC5604CK0MLQ. Pin assignments, supply domains, and peripheral multiplexing are identical across these variants. Differences lie solely in mask revision, flash content, and minor errata fixes - no PCB redesign is required when migrating between them.
