Product details
Overview
SPC560B40L3B6E0Y from STMicroelectronics is a 32-bit automotive MCU based on the Power Architecture® e200z0h core, operating at 64 MHz with 60 DMIPs performance and Variable Length Encoding (VLE). It integrates 256 KB ECC-protected Code Flash, 64 KB Data Flash, 48 KB SRAM, six FlexCAN 2.0B interfaces, and a dedicated diagnostic module for lighting control in body electronics systems.
For engineers reviewing the SPC560B40L3B6E0Y datasheet, SPC560B40L3B6E0Y pinout, SPC560B40L3B6E0Y application, or SPC560B40L3B6E0Y equivalent, key selection criteria include CAN interface count (6×), automotive-grade temperature range (−40 to +125 °C), LQFP100 package compatibility, and integrated time-triggered I/O with PWM-synchronized ADC for lighting diagnostics.
Technical Context
The device implements a dual-voltage architecture with separate VDD_HV (5 V) and VDD_BV (3.3 V) domains, supporting both supply options via internal voltage regulation. Its clock system combines FXOSC (4–16 MHz), SXOSC (32 kHz), FIRC (16 MHz), and SIRC (128 kHz), all managed by a software-controlled FMPLL and monitored by a Clock Monitor Unit (CMU).
Interrupt handling includes 16 priority levels, NMI support, and up to 34 external interrupts - 18 of which serve as wakeup lines. The memory protection unit (MPU) features 8 entries, while the Cross Triggering Unit (CTU) enables synchronized ADC sampling with PWM events for precise timing-critical diagnostics.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC560B50L3B6E0Y | 512 KB Code Flash (vs. 256 KB), same LQFP100 package and peripheral set. | Suitable for larger firmware images requiring bootloader, OTA update stack, or expanded diagnostic routines. | Select when future firmware growth or ASIL-D decomposition mandates additional flash space without changing hardware layout. |
| SPC560C40L3B6E0Y | Same flash/SRAM size but adds enhanced debug capability (Nexus2+ on LBGA208 only); not available in LQFP100. | Targeted at emulation and pre-production validation where advanced trace and profiling are required. | Not pin-compatible; choose only if migrating to LBGA208 package and requiring Nexus2+ for functional safety certification testing. |
Compared with SPC560B40L3B6E0Y, the B50 variant offers double flash capacity for complex firmware while maintaining identical I/O, timing, and CAN resources; the C40 variant trades package compatibility for deeper debug visibility - making B40 the optimal balance of production readiness, cost, and feature set for volume automotive body electronics.
