NXP Semiconductors SPC5603BF2MLH6

Overview

SPC5603BF2MLH6 from NXP Semiconductors is a 32-bit automotive microcontroller based on the Power Architecture® e200z0h core, operating up to 64 MHz with 384 KB code flash, 64 KB data flash, and 32 KB SRAM - all featuring ECC protection. It integrates six FlexCAN modules, four LINFlex interfaces, three DSPI controllers, and a 10-bit 28-channel ADC for body control unit (BCU) and gateway applications.

For engineers reviewing the SPC5603BF2MLH6 datasheet, SPC5603BF2MLH6 pinout, SPC5603BF2MLH6 application, or SPC5603BF2MLH6 equivalent, key selection criteria include its LQFP-144 package, FMPLL clock generation, Nexus 2+ debug interface, and support for AUTOSAR-compliant real-time timers (PIT/STM/RTC).

Technical Context

The SPC5603BF2MLH6 implements the e200z0h CPU core with Variable Length Encoding (VLE) for reduced code footprint and executes at up to 64 MHz using a frequency-modulated PLL (FMPLL). Its crossbar switch enables concurrent access to flash, SRAM, and peripherals by multiple bus masters including eMIOS, FlexCAN, and DSPI.

Memory subsystem includes ECC-protected 384 KB on-chip code flash, 64 KB data flash (4 × 16 KB), and 32 KB SRAM. The MPU provides 8-region memory protection with 32-byte granularity, while the INTC supports 148 interrupt vectors including 18 wakeup-capable sources.

FAQ

What is the maximum operating frequency of the SPC5603BF2MLH6?

The SPC5603BF2MLH6 operates at a maximum system clock frequency of 64 MHz, achieved via its integrated frequency-modulated phase-locked loop (FMPLL). This speed is validated across the full industrial temperature range (−40°C to +105°C) and supports real-time deterministic execution for AUTOSAR-compliant software stacks running on the e200z0h core.

Does the SPC5603BF2MLH6 support CAN FD?

No, the SPC5603BF2MLH6 supports only classical CAN 2.0B protocol through its six FlexCAN modules. It does not implement CAN FD physical layer or protocol enhancements. For CAN FD capability, engineers should evaluate newer families such as S32K1 or S32K3 series microcontrollers from NXP.

What debug interface does the SPC5603BF2MLH6 provide?

The SPC5603BF2MLH6 features a Nexus 2+ development interface compliant with IEEE-ISTO 5001-2003 Class Two Plus standard. This enables real-time instruction trace, data watchpoints, non-intrusive profiling, and hardware-assisted breakpoints - essential for AUTOSAR stack validation and ISO 26262 tool qualification workflows.

How many ADC channels does the SPC5603BF2MLH6 have, and what is their resolution?

The SPC5603BF2MLH6 integrates a 10-bit analog-to-digital converter with 28 input channels. It supports configurable sample-and-hold timing, hardware triggering via CTU from eMIOS or PIT, and conversion results stored in dedicated result buffers - enabling synchronized multi-sensor acquisition for body electronics sensing.

Is the SPC5603BF2MLH6 pin-compatible with other MPC560xB/C devices?

Yes, the SPC5603BF2MLH6 in 144 LQFP package shares identical pinout with other MPC560xB/C variants in the same package option (e.g., MPC5604BF2MLH6, SPC5603BK0MLH6), allowing PCB reuse across memory or temperature grade variants. Signal mapping, power pin locations, and debug interface pins are fully aligned per NXP's MPC5604B/C datasheet Rev. 15.
