Product details
Overview
SPC560P44L3CEABY from STMicroelectronics is a 32-bit Power Architecture® e200z0h-based automotive MCU with 576 KB on-chip Flash (ECC-protected), 40 KB SRAM (ECC-protected), and integrated FlexCAN 2.0B, FlexRay V2.1, LINFlex, DSPI, eTimer, FlexPWM, and dual 10-bit ADCs - designed for chassis control and safety-critical functions in airbag, brake, and steering ECUs.
For engineers reviewing the SPC560P44L3CEABY datasheet, SPC560P44L3CEABY pinout, SPC560P44L3CEABY application, or SPC560P44L3CEABY equivalent, key selection considerations include ECC-protected memory architecture, ASIL-B-capable fault collection unit (FCU), Nexus L2+ debug interface, dual-channel FlexRay up to 10 Mbit/s, and safety port configurable as secondary CAN at 7.5 Mbit/s.
Technical Context
The SPC560P44L3CEABY implements a single-issue, 64 MHz e200z0h CPU core compliant with Power Architecture® embedded category and supporting Variable Length Encoding (VLE) for code density optimization. Its memory subsystem includes 512 KB main Flash with ECC and erase/program controller, plus 64 KB data Flash (4 × 16 KB banks) for EEPROM emulation - both with error detection and correction logic.
Real-time determinism is enforced via a 16-channel eDMA controller, 16-level priority interrupt controller, and dual eTimer units (6 timers each, 16-bit cascadable, quadrature decode capable). Safety integrity is enhanced by non-maskable interrupt (NMI), programmable software watchdog timer (SWT), and dedicated Fault Collection Unit (FCU) that captures and reports system faults without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive chassis and safety applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC560P50L3CEABY | Same LQFP100 package; 576 KB Flash, but with full 512 KB main Flash + 64 KB data Flash enabled (vs. 448 KB + 64 KB in P44 variant) | Required where full Flash capacity needed for complex safety diagnostics or dual-application images | Select when >448 KB code space or certified bootloader partitioning is mandatory |
| MPC5604B | Freescale (now NXP) 64 MHz e200z0 core; 512 KB Flash, 40 KB SRAM, no FlexRay; supports JTAG/Nexus but lacks safety port FlexCAN | Legacy chassis designs without FlexRay or functional safety port requirements | Choose only for brownfield migration where FlexRay and ASIL-B safety port are not required |
Compared with SPC560P44L3CEABY, the P50L3 offers greater Flash headroom for safety-certified code partitions, while the MPC5604B provides legacy compatibility but omits FlexRay and the hardware-isolated safety port - making it unsuitable for new ASIL-B chassis designs requiring dual-bus redundancy.

FAQ
What is the maximum operating temperature range for SPC560P44L3CEABY?
The SPC560P44L3CEABY is qualified for automotive Grade 2 operation: –40 °C to +105 °C ambient temperature. This rating is validated per AEC-Q100 Rev G, including extended temperature life testing and thermal cycling over 1,000 cycles. Junction temperature must remain ≤125 °C under worst-case power dissipation conditions.
Does SPC560P44L3CEABY support AUTOSAR OS and MCAL drivers?
Yes - ST provides certified AUTOSAR 4.2.2 and 4.3.1 MCAL drivers (including CAN, LIN, FlexRay, ADC, PWM, and DIO) and supports integration with leading AUTOSAR OS vendors (ETAS, Vector, Elektrobit). The MCU's memory protection unit (MPU), ECC, and Nexus L2+ trace meet AUTOSAR BSW qualification requirements.
How is the safety port FlexCAN different from the standard FlexCAN interface?
The safety port FlexCAN uses physically separate message RAM, dedicated transmit/receive buffers, and independent clock domain - enabling hardware isolation from the primary FlexCAN. It supports up to 7.5 Mbit/s and can be configured either as a second CAN channel or as a fail-operational safety path with distinct error counters and status registers.
Can SPC560P44L3CEABY operate with a 3.3 V supply only, or does it require 5 V for certain peripherals?
The SPC560P44L3CEABY supports dual-supply operation: VDD_HV_IOx pins accept either 3.3 V ±10% or 5.0 V ±10%, while VDD_HV_REG (ADC reference) must match the selected I/O voltage. All digital I/Os are 5 V-tolerant regardless of supply mode, but ADC accuracy is optimized at the chosen supply voltage per datasheet Table 10/11.
