For engineers reviewing the SPC5747CK1VKU6R datasheet, SPC5747CK1VKU6R pinout, SPC5747CK1VKU6R application, or SPC5747CK1VKU6R equivalent, this page delivers verified technical context, validated pin mapping for the 176-pin LQFP-EP package, real-world use cases in automotive networking, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The SPC5747CK1VKU6R implements a triple-core architecture with two high-performance e200z4 CPUs (160 MHz, VLE-enabled, single-precision FPU, 8 KB I-cache/4 KB D-cache) and one e200z2 CPU (80 MHz, VLE-only), all sharing a 64-bit AHB bus with end-to-end SECDED ECC across flash, RAM, and interconnects. Memory subsystem includes 4 MB flash (with RWW capability), 512 KB SRAM distributed across three ports, and triple-port flash controller with three page buffers.
Peripheral integration centers on automotive communication: eight FlexCAN3 modules (all supporting CAN FD), 18 LINFlexD channels, four DSPI, six SPI, four I²C, dual ADC (10-bit + 12-bit), three analog comparators, and dual Ethernet interfaces (10/100 MII/RMII with AVB, IEEE 1588, multi-queue). Clocking uses FXOSC (8–40 MHz), SXOSC (32 kHz), FIRC (16 MHz), SIRC (128 kHz), and FMPLL with RTC and CMU.
