STMicroelectronics SPC560B40L3B3E0X

Overview

SPC560B40L3B3E0X 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 lighting diagnostic module for body electronics control in door modules and seat controllers.

For engineers reviewing the SPC560B40L3B3E0X datasheet, SPC560B40L3B3E0X pinout, SPC560B40L3B3E0X application, or SPC560B40L3B3E0X equivalent, key selection criteria include CAN interface count, -40 to 125 °C operation, integrated CTU for ADC synchronization, and LQFP100 package compatibility with automotive ECU layout constraints.

Technical Context

This MCU implements a dual-voltage architecture with separate VDD_HV (5 V or 3.3 V) and VDD_BV domains, supporting ultra-low-power standby with RTC, SRAM retention, and CAN bus monitoring. Its clock system combines FXOSC (4–16 MHz), SXOSC (32 kHz), FIRC (16 MHz), SIRC (128 kHz), and software-controlled FMPLL for flexible timing synthesis.

The peripheral set includes six 32-bit periodic interrupt timers, four 32-bit system timers, real-time clock, watchdog, and 16-bit counter time-triggered I/Os with up to 56 PWM/MC/IC/OC channels. The CTU enables ADC diagnostics by cross-triggering conversions with PWM edges-critical for closed-loop lighting control accuracy.

FAQ

What is the maximum operating frequency of the SPC560B40L3B3E0X e200z0h core?

The e200z0h CPU operates at a maximum frequency of 64 MHz, delivering 60 DMIPs performance. This speed is achieved using the FMPLL with input from the 4–16 MHz fast external crystal oscillator or 16 MHz internal RC oscillator, and is validated across the full -40 to 125 °C temperature range per AEC-Q100 Grade 1 specifications.

Does the SPC560B40L3B3E0X support CAN FD or only classical CAN 2.0B?

The SPC560B40L3B3E0X supports only Classical CAN 2.0B (ISO 11898-1) across all six FlexCAN interfaces. It does not implement CAN FD protocol features such as variable bit rate or extended data length. Each FlexCAN module supports up to 64 message objects and bit rates up to 1 Mbps, consistent with legacy automotive body network requirements.

How many GPIO pins are available in the LQFP100 package variant?

The SPC560B40L3B3E0X in LQFP100 provides 75 GPIO pins, as confirmed in Table 1 and Section 3.6 of the datasheet. These include dedicated analog inputs, PWM outputs, CAN transceiver lines, and configurable digital I/Os - all accessible on the 100-pin footprint with defined electrical characteristics per Tables 16–20.

Is the SPC560B40L3B3E0X qualified for automotive use per AEC-Q100?

Yes, the SPC560B40L3B3E0X is AEC-Q100 qualified for Grade 1 (-40 to 125 °C), with full qualification documentation referenced in ST's official product change notifications and datasheet revision history. It meets stress test requirements for HTOL, TCT, ESD, and latch-up, and supports functional safety development per ISO 26262 ASIL-B through its ECC memory, lockstep-capable peripherals, and diagnostic libraries.
