SPC574S64E3CEFAR

SPC574S64E3CEFAR is an automotive-grade 32‑bit microcontroller in NXP’s SPC5 family, designed for real‑time control tasks such as motor drives, powertrain electronics, and body electronics. It uses a Power Architecture core and provides a rich set of peripherals typical for automotive MCUs, including multiple CAN/CAN-FD channels, serial interfaces (UART/SPI/I2C), high‑speed PWM and timer/motor-control units, several 12‑bit ADCs, and other I/O. The part number encodes package, memory, and temperature grade; the “S64” portion hints at a specific RAM/flash configuration for this variant. It offers automotive-grade temperature range and safety features suitable for ASIL environments, and is supported by NXP development tools and software libraries. For exact specs (clock speed, memory size, peripheral count), consult the official SPC574S64E3CEFAR datasheet and product selector.
