STMicroelectronics SPC560B40L5B6E0X

Overview

SPC560B40L5B6E0X 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 extended temperature operation up to 125 °C.

For engineers reviewing the SPC560B40L5B6E0X datasheet, SPC560B40L5B6E0X pinout, SPC560B40L5B6E0X application, or SPC560B40L5B6E0X equivalent, key selection considerations include its dual-voltage supply (3.3 V/5 V), six FlexCAN 2.0B interfaces, time-triggered I/O with 56-channel PWM/MC/IC/OC capability, and dedicated lighting diagnostic module with PWM-synchronized ADC measurements.

Technical Context

The device implements a deterministic real-time architecture centered on the e200z0h CPU with hardware memory protection (8-entry MPU), non-maskable interrupt (NMI), and 34 external interrupt sources including 18 wakeup lines. Its clock system combines four oscillators (FXOSC, SXOSC, FIRC, SIRC) with software-controlled FMPLL and Clock Monitor Unit (CMU) for robust timing supervision.

Peripheral integration includes a cross-triggering unit (CTU) linking ADC conversions to PWM events, six FlexCAN controllers each supporting 64 message objects, four LINFlex/UART channels, three DSPI/I²C interfaces, and a real-time clock timer - all designed for coordinated, low-latency execution in automotive body domain controllers.

FAQ

What is the maximum junction temperature rating for SPC560B40L5B6E0X?

The device is qualified for operation up to +125 °C ambient temperature, with a maximum junction temperature of +150 °C under specified thermal conditions (θ_JA = 40 °C/W, T_A = 125 °C, P_D ≤ 1.25 W). Thermal derating curves and package-specific θ_JC values are provided in Section 3.14 of the datasheet.

Does SPC560B40L5B6E0X support JTAG debugging?

Yes, the device supports IEEE 1149.1 JTAG boundary scan for production testing and debug, with dedicated TDI, TMS, TDO, TCK, and TRST pins. JTAG characteristics including timing and voltage thresholds are fully specified in Table 49 and Figure 33 of the datasheet.

Can the internal 16 MHz FIRC oscillator be used as the main system clock source?

Yes, the Fast Internal RC Oscillator (FIRC) can serve as the primary clock source via the FMPLL or directly through the clock multiplexer. Its accuracy is ±2% over temperature and voltage, sufficient for non-timing-critical functions like LIN communication or background tasks, but not for CAN or RTC.

How many GPIO pins are available in the LQFP64 package variant?

The SPC560B40L5B6E0X in LQFP64 provides 45 GPIO-capable pins, as confirmed in the device summary table and pin configuration diagrams (Figure 2). All GPIOs support interrupt generation, programmable pull-up/down, and multiple alternate functions including CAN, LIN, SPI, and ADC inputs.
