NXP Semiconductors SPC5604CAMLH6

Overview

SPC5604CAMLH6 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, a 10-bit ADC (36-channel), and real-time peripherals including RTC, PIT, and STM for body electronics control applications.

For engineers reviewing the SPC5604CAMLH6 datasheet, SPC5604CAMLH6 pinout, SPC5604CAMLH6 application, or SPC5604CAMLH6 equivalent, key selection criteria include its 144-pin LQFP (20 × 20 mm) package, FMPLL clock generation, crossbar switch architecture for concurrent bus access, Nexus 2+ debug interface per IEEE-ISTO 5001-2003, and automotive-grade functional safety support via MPU and memory ECC.

Technical Context

The SPC5604CAMLH6 implements the e200z0h CPU core with Variable Length Encoding (VLE) for reduced code footprint and executes at up to 64 MHz. Its FMPLL provides programmable frequency modulation and supports multiple clock sources including 4–16 MHz external crystal, 32 kHz oscillator, and internal 16 MHz/128 kHz RC oscillators.

Peripherals are interconnected via a 64-bit 2×3 crossbar switch enabling simultaneous access by CPU, DMA, and debug masters to flash, SRAM, and peripherals. The SIUL (System Integration Unit Lite) manages 123 configurable GPIOs with interrupt/wakeup capability across 18 external sources, while the INTC supports 148 vectors with priority-based preemption.

Key Specifications

Pinout & Package

SPC5604CAMLH6 is housed in a 144-pin LQFP (20 × 20 × 1.4 mm) package with exposed thermal pad. Pin assignments follow the MPC5604B/C family pinout defined in Figure 5 of the Rev. 15 datasheet, supporting dual-voltage operation (1.2 V core / 3.3 V I/O) and dedicated analog supply rails (VDD_HV_ADC/VSS_HV_ADC).

FAQ

What is the maximum operating temperature range for the SPC5604CAMLH6?

The SPC5604CAMLH6 is qualified for operation from −40 °C to +125 °C ambient temperature, meeting AEC-Q100 Grade 2 requirements for under-hood and cabin-mounted automotive ECUs. This rating is validated across all electrical parameters including flash endurance, ADC accuracy, and CAN timing margins per Rev. 15 datasheet Section 2.13.

Does the SPC5604CAMLH6 support CAN FD?

No, the SPC5604CAMLH6 integrates six FlexCAN modules compliant with ISO 11898-1 (Classical CAN only) and does not support CAN FD data rates or frame formats. For CAN FD capability, NXP recommends migrating to the SPC5605 or S32K series, as confirmed in the MPC5604B/C datasheet Table 1 and Section 2.27.4.

How many FlexCAN modules are implemented in the SPC5604CAMLH6?

The SPC5604CAMLH6 implements six FlexCAN modules (CAN0–CAN5), as specified in Table 1 of the MPC5604B/C datasheet Rev. 15. All six modules support configurable message buffers, loopback testing, and error counters - enabling full vehicle network participation in gateways or high-channel-count nodes.

Is the SPC5604CAMLH6 pin-compatible with other MPC5604 variants?

Yes, the SPC5604CAMLH6 shares identical 144-pin LQFP mechanical and electrical pinout with all MPC5604B/C devices in the same package option (e.g., MPC5604BAMLH6, MPC5604CAMLH6), including matching power, ground, reset, oscillator, and peripheral signal assignments per Figure 5 of the datasheet.

What debug interface does the SPC5604CAMLH6 provide?

The SPC5604CAMLH6 features a Nexus 2+ development interface compliant with IEEE-ISTO 5001-2003 Class Two Plus, supporting real-time trace, hardware breakpoints, and non-intrusive debugging. It also includes JTAG (IEEE 1149.1) for boundary scan and basic programming, as detailed in Sections 2.7 and 2.27.3 of the datasheet.
