STM32MP151CAB3T

The STM32MP151CAB3T is an STM32MP1-series microprocessor IC featuring an ARM® Cortex®-A7 application core (1 core, 32‑bit) designed for embedded systems. It integrates an ARM® Cortex®-M4 coprocessor for real-time tasks and provides a compact 354‑LFBGA (16×16) surface‑mount package for space‑constrained designs.

Engineered for embedded applications that require a combination of application processing, real‑time control and integrated I/O, the device offers on‑chip display controllers, graphics acceleration and a broad set of connectivity interfaces alongside support for multiple DRAM types.

Key Features

• Core & Coprocessor — ARM® Cortex®-A7 main processor (1 core, 32‑bit, 209 MHz) paired with an ARM® Cortex®-M4 coprocessor for offloading real‑time control and deterministic tasks.
• Memory Support — Integrated memory controllers for DDR3, DDR3L, LPDDR2 and LPDDR3 for flexible system memory configurations.
• Display & Graphics — Built‑in display interface controllers (HDMI‑CEC, LCD) and graphics acceleration to support graphical user interfaces and multimedia display functions.
• Connectivity — On‑chip networking and peripheral interfaces including 10/100 Mbps Ethernet, multiple USB 2.0 ports and USB 2.0 OTG with PHY, and CAN for vehicle and industrial bus applications.
• Security — ARM TZ (ARM TrustZone) security feature listed to enable hardware‑assisted trusted execution and partitioning.
• Package & Mounting — 354‑LFBGA (16×16) supplier device package in a surface‑mount format for compact PCB layouts.
• Operating Range & Compliance — Extended operating temperature range from −40 °C to 125 °C and RoHS compliance for environmental regulation adherence.

Typical Applications

• Industrial Control: Use the Cortex‑M4 coprocessor for deterministic motor control and sensor processing while the Cortex‑A7 handles system management and HMI tasks.
• Human‑Machine Interfaces (HMIs): On‑chip LCD and HDMI‑CEC support with graphics acceleration enables responsive graphical interfaces and display management.
• Embedded Networking Gateways: 10/100 Mbps Ethernet with multiple USB and CAN interfaces suits protocol bridging and edge‑gateway designs.
• Multimedia Devices: Graphics acceleration and display controllers support multimedia playback and user interface rendering in compact embedded products.

Unique Advantages

• Integrated Heterogeneous Processing: Combines an ARM® Cortex®-A7 application core with an ARM® Cortex®-M4 coprocessor to separate high‑level application workloads from real‑time control, simplifying system partitioning.
• Flexible Memory Options: Support for DDR3, DDR3L, LPDDR2 and LPDDR3 enables designers to select memory types that balance performance, power and cost.
• Rich Peripheral Set: Native support for Ethernet, multiple USB interfaces, CAN and display controllers reduces external component count and BOM complexity.
• Security Foundation: ARM TrustZone (ARM TZ) is included to facilitate hardware‑based security domains and trusted execution environments.
• Wide Thermal Range: Operation from −40 °C to 125 °C provides headroom for demanding environmental conditions.
• Compact Surface‑Mount Package: 354‑LFBGA (16×16) package supports dense PCB integration while retaining extensive I/O and functionality.
