NXP Semiconductors SPC5604BAVLQ6R

Overview

SPC5604BAVLQ6R 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 SPC5604BAVLQ6R datasheet, SPC5604BAVLQ6R pinout, SPC5604BAVLQ6R application, or SPC5604BAVLQ6R equivalent, key selection considerations include its LQFP-100 package, FMPLL clock generation, Nexus 2+ debug interface, real-time counter with autonomous wakeup, and support for AUTOSAR-compliant timing via STM and PIT modules.

Technical Context

The SPC5604BAVLQ6R implements a single-issue e200z0h CPU core with Variable Length Encoding (VLE) for reduced code footprint and operates 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, DSPI, and FlexCAN.

It features an interrupt controller (INTC) supporting 148 vectors, memory protection unit (MPU) with eight region descriptors, boot assist module (BAM) for serial flash programming via CAN or SCI, and integrated voltage regulation with dedicated 1.2 V low-voltage supply domains.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the SPC5604BAVLQ6R?

The SPC5604BAVLQ6R 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 −40°C to +105°C temperature range and supports real-time execution of AUTOSAR OS tasks, LINFlex protocol stacks, and FlexCAN message handling without jitter.

Does the SPC5604BAVLQ6R support AUTOSAR-compliant timing services?

Yes, the SPC5604BAVLQ6R supports AUTOSAR timing services through its System Timer Module (STM) and six Periodic Interrupt Timers (PIT) with 32-bit resolution. These modules provide precise, deterministic timing for OS tick generation, schedule tables, and time-triggered communication - all accessible via standardized AUTOSAR BSW drivers.

What debug interface does the SPC5604BAVLQ6R provide?

The SPC5604BAVLQ6R includes a Nexus development interface (NDI) compliant with IEEE-ISTO 5001-2003 Class Two Plus, delivering real-time trace, hardware breakpoints, data watchpoints, and non-intrusive program flow analysis. It uses dedicated MDO[0–3], MCKO, and EVTO pins on the 100 LQFP package for full visibility during ECU development and validation.

How many CAN interfaces does the SPC5604BAVLQ6R integrate?

The SPC5604BAVLQ6R integrates six enhanced full CAN (FlexCAN) modules, each with configurable message buffers and support for CAN 2.0A/B protocols. All six modules are functional in the LQFP-100 variant and can operate simultaneously - enabling multi-domain networking such as body, chassis, and infotainment CAN buses within a single ECU.

Is the SPC5604BAVLQ6R pin-compatible with other members of the SPC5604B/C family?

No - the SPC5604BAVLQ6R is not universally pin-compatible across the SPC5604B/C family. While it shares the 100 LQFP footprint with variants like SPC5604CFVLQ6R and MPC5604BK0MLQ6R, pin functions differ due to peripheral mapping variations (e.g., CTU presence, eMIOS channel count, ADC channel allocation). Always verify signal assignments against the specific device's pinout table before board reuse.
