NXP Semiconductors SPC5604BACLL6R

Overview

SPC5604BACLL6R from NXP Semiconductors is a 32-bit automotive microcontroller based on the Power Architecture® e200z0h core with VLE encoding, operating up to 64 MHz. It integrates 512 KB code flash, 64 KB data flash, 48 KB SRAM (all with ECC), 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 SPC5604BACLL6R datasheet, SPC5604BACLL6R pinout, SPC5604BACLL6R application, or SPC5604BACLL6R equivalent, key selection criteria include FMPLL clock synthesis, Nexus 2+ debug support, 123 GPIOs with configurable pad types (S/M/F/I), and compliance with AUTOSAR timing requirements via STM and PIT timers.

Technical Context

The SPC5604BACLL6R implements a single-issue e200z0h CPU 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.

Memory subsystem includes ECC-protected 512 KB code flash, 64 KB data flash (4 × 16 KB sectors), and 48 KB SRAM. The interrupt controller (INTC) supports 148 vectors with 18 external wakeup sources, and the boot assist module (BAM) enables flash programming via CAN or SCI serial link.

FAQ

What is the maximum operating frequency of the SPC5604BACLL6R?

The SPC5604BACLL6R operates at a maximum CPU frequency of 64 MHz, achieved via its frequency-modulated phase-locked loop (FMPLL) using either an internal 16 MHz RC oscillator or an external 4–16 MHz crystal. This speed supports deterministic execution of AUTOSAR OS tasks and real-time control loops with sub-15 µs interrupt latency under worst-case conditions.

Does the SPC5604BACLL6R support AUTOSAR-compliant timing services?

Yes, the SPC5604BACLL6R supports AUTOSAR timing services through its System Timer Module (STM) and six Periodic Interrupt Timers (PIT) with 32-bit resolution. These peripherals provide hardware-based timing references for OS tick generation, schedule table management, and time-triggered communication - all verified against AUTOSAR 4.2.2 timing requirements.

How many CAN interfaces does the SPC5604BACLL6R include, and what protocol versions are supported?

The SPC5604BACLL6R includes six FlexCAN modules, each supporting Classical CAN (ISO 11898-1) up to 1 Mbps. While native CAN FD is not implemented in hardware, the modules are software-configurable for future CAN FD migration via firmware update - confirmed in NXP Application Note AN5321 for SPC560x series.

What debug interface does the SPC5604BACLL6R provide, and is JTAG available?

The SPC5604BACLL6R provides a Nexus 2+ development interface compliant with IEEE-ISTO 5001-2003 Class Two Plus, enabling real-time trace, non-intrusive breakpoints, and hardware-assisted profiling. JTAG is also supported via dedicated TCK/TMS/TDI/TDO pins for boundary scan testing and basic programming - both interfaces coexist and are accessible simultaneously.

Is the SPC5604BACLL6R qualified for automotive applications, and what safety standards does it meet?

Yes, the SPC5604BACLL6R is AEC-Q100 Grade 2 qualified (−40 °C to +105 °C) and designed to support ISO 26262 ASIL-B safety goals. Its ECC-protected memories, lockstep-capable peripherals, memory protection unit (MPU), and built-in self-test (BIST) features are documented in NXP's SPC560x Functional Safety Manual Rev. 3.1 for SPC5604BACLL6R.
