STMicroelectronics SPC560B40L3C6E0X

Overview

SPC560B40L3C6E0X 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 Code Flash with ECC, 64 KB Data Flash with ECC, and 48 KB SRAM with ECC, targeting body electronics control in vehicles requiring ASIL-B compliance support and -40 to 125 °C operation.

For engineers reviewing the SPC560B40L3C6E0X datasheet, SPC560B40L3C6E0X pinout, SPC560B40L3C6E0X application, or SPC560B40L3C6E0X equivalent, key selection considerations include its dual-supply capability (3.3 V or 5 V), six FlexCAN 2.0B interfaces, time-triggered I/O with up to 56 PWM/MC/IC/OC channels, and dedicated lighting diagnostic module with PWM-synchronized ADC measurements.

Technical Context

The device implements a deterministic real-time architecture with 16 priority-level interrupt controller, non-maskable interrupt (NMI), and up to 34 external interrupts including 18 wakeup lines. Its clock system combines four oscillators - 4–16 MHz FXOSC, 32 kHz SXOSC, 16 MHz FIRC, and 128 kHz SIRC - managed by software-controlled FMPLL and monitored by Clock Monitor Unit (CMU).

Peripheral integration includes three DSPI/I²C modules, four LINFlex/UART interfaces, six-channel periodic interrupt timers, four-channel system timer, RTC, and a cross-triggering unit (CTU) enabling ADC diagnostics and synchronized sampling across analog and timing domains.

FAQ

What is the maximum junction temperature specification for SPC560B40L3C6E0X?

The device is rated for operation up to 125 °C ambient temperature, with a maximum junction temperature of 150 °C under specified thermal conditions. This rating is validated per AEC-Q100 Grade 1 requirements and supported by thermal resistance data (θ_JA = 35 °C/W for LQFP100) in the official datasheet Section 3.14.

Does SPC560B40L3C6E0X support JTAG debugging in production units?

Yes - the device integrates a Nexus1 debug interface compliant with IEEE-ISTO 5001-2003, supporting full boundary scan, real-time trace, and non-intrusive breakpoints. JTAG pins (TCK, TMS, TDI, TDO, TRST) are accessible on the LQFP100 package and enabled in all operational modes except deep stop.

How many CAN message objects are available per FlexCAN interface?

Each of the six FlexCAN interfaces supports 64 independent message objects, configurable as transmit, receive, or FIFO buffers. This allows concurrent handling of multiple CAN IDs and data lengths without CPU intervention, essential for multi-domain communication in body control gateways.

Is the 10-bit ADC capable of simultaneous sampling across multiple channels?

No - the ADC performs sequential conversions, but the Cross Triggering Unit (CTU) enables hardware-synchronized start-of-conversion across up to 36 channels using external triggers such as PWM edges or timer events, achieving effective simultaneity within ±50 ns jitter for closed-loop control.
