It integrates 512 KB code flash, 64 KB data flash, 48 KB SRAM (all with ECC), and supports up to 6 FlexCAN modules, 4 LINFlex interfaces, and a 10-bit ADC with 36 channels - deployed in body control modules for vehicle lighting and door actuation.

For engineers reviewing the SPC5604BAVLQ6 datasheet, SPC5604BAVLQ6 pinout, SPC5604BAVLQ6 application, or SPC5604BAVLQ6 equivalent, key selection criteria include its LQFP-144 package, FMPLL clock generation, Nexus 2+ debug interface per IEEE-ISTO 5001-2003, and automotive-grade qualification per AEC-Q100 Grade 2 (–40°C to +105°C).

Technical Context

The SPC5604BAVLQ6 implements a single-issue e200z0h CPU core with Variable Length Encoding (VLE) for reduced code footprint and optimized low-power execution. Its crossbar switch architecture enables concurrent access to flash, SRAM, and peripherals by multiple bus masters including eMIOS, FlexCAN, and DSPI modules.

It features an integrated FMPLL for programmable frequency modulation, a memory protection unit (MPU) with 8 region descriptors, and boot assist via CAN/SCI serial link. The device includes a real-time counter (RTC) with autonomous wakeup at 1 ms resolution and a system timer module (STM) compliant with AUTOSAR timing requirements.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the SPC5604BAVLQ6?

The SPC5604BAVLQ6 operates at a maximum frequency of 64 MHz, achieved via its integrated FMPLL. This frequency is validated across the full AEC-Q100 Grade 2 temperature range (–40°C to +105°C) and supports deterministic real-time execution for automotive body control applications. The e200z0h core maintains consistent timing behavior at this speed, enabling reliable AUTOSAR OS scheduling.

Does the SPC5604BAVLQ6 support CAN FD or only classical CAN?

The SPC5604BAVLQ6 supports only classical CAN (ISO 11898-1) through its six FlexCAN modules - it does not implement CAN FD protocol features such as variable bit rate or extended data length. Each FlexCAN module is configurable for standard or extended identifiers and supports up to 64 message buffers, making it suitable for legacy and current-generation automotive networks.

What debug interface does the SPC5604BAVLQ6 provide?

The SPC5604BAVLQ6 provides a Nexus 2+ development interface compliant with IEEE-ISTO 5001-2003 Class Two Plus, including real-time trace, non-intrusive breakpoints, and data watchpoints. It uses dedicated pins (MDO0–MDO3, MCKO, EVTO, MSEO) and supports high-speed streaming of program flow and data access - essential for AUTOSAR stack validation and functional safety certification.

Is the SPC5604BAVLQ6 pin-compatible with other members of the SPC5604 family?

Yes, the SPC5604BAVLQ6 shares identical pinout and footprint with other SPC5604x variants in the 144-pin LQFP package (e.g., SPC5604PKLQ6, SPC5604BVLQ6), including matching signal assignments for power, reset, clocks, and all peripheral I/O. This allows direct substitution within the same hardware design when upgrading features like temperature grade or flash configuration.

What is the role of the Boot Assist Module (BAM) in the SPC5604BAVLQ6?

The Boot Assist Module (BAM) in the SPC5604BAVLQ6 is a ROM-resident bootloader that enables in-system programming of internal flash memory via CAN or SCI serial interfaces. It executes automatically on reset when configured for serial boot mode, allowing field firmware updates without JTAG hardware - a key requirement for secure OTA update architectures in modern vehicles.
