NXP Semiconductors SPC5604CK0MLH6R

Overview

SPC5604CK0MLH6R 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 for body electronics control in vehicle door modules, lighting systems, and seat control units.

For engineers reviewing the SPC5604CK0MLH6R datasheet, SPC5604CK0MLH6R pinout, SPC5604CK0MLH6R application, or SPC5604CK0MLH6R equivalent, key selection criteria include FMPLL clock generation, Nexus 2+ debug support, 144-pin LQFP package compatibility, and automotive-grade AEC-Q100 qualification per Rev. 15 datasheet.

Technical Context

The SPC5604CK0MLH6R 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 an interrupt controller (INTC) supporting 148 vectors, memory protection unit (MPU) with eight region descriptors, and boot assist module (BAM) enabling flash programming via CAN or SCI. The device includes dedicated hardware blocks for real-time control: RTC with 1 ms wakeup resolution, six PIT timers, STM, and CTU for synchronized ADC triggering.

Key Specifications

Pinout & Package

SPC5604CK0MLH6R is housed in a 144-pin LQFP package (20 × 20 × 1.4 mm, 0.5 mm pitch) with exposed thermal pad for enhanced heat dissipation in automotive environments. Pin functions are multiplexed across GPIO, peripheral, and system roles, with dedicated voltage domains (VDD_HV/VSS_HV, VDD_LV/VSS_LV, VDD_BV, VDD_HV_ADC/VSS_HV_ADC) and reset-phase tristate behavior.

FAQ

What is the maximum operating temperature range for the SPC5604CK0MLH6R?

The SPC5604CK0MLH6R is qualified to AEC-Q100 Grade 2, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is validated per Rev. 15 datasheet and applies to the full 144-pin LQFP package, making it suitable for under-dash and cabin-mounted automotive applications where thermal margins are critical. The device includes on-chip thermal monitoring via the SSCM module.

Does the SPC5604CK0MLH6R support CAN FD or only classical CAN?

The SPC5604CK0MLH6R supports only classical CAN (ISO 11898-1) through its six FlexCAN modules - it does not implement CAN FD protocol features such as variable bit rates or extended data length. Each FlexCAN module is configurable for up to 64 message buffers and supports hardware acceptance filtering, but lacks the transceiver-independent FD arbitration and data phase handling found in later SPC56xx or S32K families.

How many ADC channels does the SPC5604CK0MLH6R support, and what is their resolution?

The SPC5604CK0MLH6R integrates a single 10-bit successive approximation register (SAR) ADC with up to 36 input channels, as confirmed in Table 1 of the Rev. 15 datasheet. Channel count depends on pin multiplexing configuration; the ADC supports simultaneous sampling via CTU synchronization and includes built-in offset/gain calibration registers accessible through the ECSM module.

Is the SPC5604CK0MLH6R pin-compatible with other members of the MPC5604B/C family?

Yes - the SPC5604CK0MLH6R shares identical 144-pin LQFP mechanical dimensions, pad layout, and signal mapping with all MPC5604B/C variants in the same package option (e.g., MPC5604BK0MLH6R, MPC5604CK0MLH6A). Pin-to-pin compatibility extends to power, ground, reset, clock, JTAG, Nexus, and peripheral signal assignments, enabling direct substitution where flash/RAM requirements align.

What debug interface does the SPC5604CK0MLH6R provide, and is external hardware required?

The SPC5604CK0MLH6R includes a Nexus 2+ development interface compliant with IEEE-ISTO 5001-2003 Class Two Plus, accessible via dedicated MDO/MCKO/EVTO pins. Debug requires an external Nexus-capable probe (e.g., Lauterbach TRACE32 or iSystem winIDEA); no on-chip debug ROM or SWD/JTAG-only fallback is provided - the interface supports real-time trace, hardware breakpoints, and memory access without halting CPU execution.
