528 MHz Cortex-M7 crossover processor
The NXP MIMXRT1052CVL5A557 is a 32-bit ARM Cortex-M7 crossover MCU from the RT1050 series, clocked at 528 MHz. It integrates 512 KB of on-chip SRAM and relies on external program memory, which keeps the BOM flexible for flash density choices. The 528 MHz core speed places it well above typical Cortex-M4 parts — this chip handles real-time control loops and lightweight GUI rendering without an external application processor.
Connectivity and I/O for system integration
This part carries Ethernet, USB OTG, CAN, and multiple serial interfaces (SPI, I²C, UART/USART, SAI, SPDIF) on a single die. The 127 GPIO lines and 20-channel 12-bit ADC reduce the need for external port expanders or analog front-ends in sensor-heavy designs. The 196-LFBGA (10x10 mm) package fits compact PCBs but requires careful fan-out routing for the BGA balls.
Industrial temperature grade and operating conditions
Rated for junction temperatures from -40°C to 105°C, this MCU suits factory automation, outdoor telecom cabinets, and under-hood automotive modules where ambient heat exceeds commercial-grade limits.
