STM32MP151CAD3T

Microprocessors Overview

The STM32MP151CAD3T is a microprocessor IC from the STM32MP1 series, manufactured by STMicroelectronics. It features a single 32-bit Arm Cortex-A7 core operating at up to 650 MHz and a 32-bit Arm Cortex-M4 real-time coprocessor running at up to 209 MHz. The device integrates 708 Kbytes of internal SRAM and supports external DDR memory up to 1 Gbyte via LPDDR2/LPDDR3 or DDR3/DDR3L interfaces. It is housed in a 257-TFBGA package measuring 10x10 mm with a 0.5 mm pitch.

Microprocessors Feature Summary

• Heterogeneous dual-core architecture combining an application processor (Cortex-A7) for Linux and a real-time coprocessor (Cortex-M4) for deterministic tasks.
• Integrated LCD-TFT display controller supporting parallel RGB interfaces for direct connection to TFT panels.
• Hardware security features including Arm TrustZone, secure boot capabilities, active tamper detection, and hardware cryptographic accelerators.
• Comprehensive peripheral set including Gigabit Ethernet MAC, USB Host/OTG controllers, SDMMC interfaces, and multiple communication buses.

Microprocessors Applications

• Industrial Human Machine Interfaces (HMI)
• Smart home gateways and thermostats
• Point of Sale (POS) terminals
• Medical patient monitoring devices

Microprocessors Procurement Notes

Verify the specific ordering suffix CAD3T against the manufacturer's official datasheet to confirm package type, temperature range, and mass packaging format. Ensure compatibility with required power management integrated circuits (PMICs) such as the STPMIC1A for proper voltage regulation and system startup sequences.

Microprocessors Selection Notes

Select this component when a single-core Cortex-A7 configuration is sufficient for the target application workload. Compare pin counts and I/O availability against larger packages like TFBGA361 if additional peripherals are required. Confirm that the 650 MHz processing speed meets the performance requirements for the intended Linux distribution and graphical user interface complexity.

Microprocessors Part Context

This part belongs to the STM32MP151 product line within the broader STM32MP1 microprocessor family. It shares the same core architecture and peripheral ecosystem as other variants in the series but differs in package options and clock speeds. It is designed to work alongside dedicated power management ICs to form a complete embedded computing solution.
