SCIMX516AJM6CR2 - i.MX51 32-Bit ARM Cortex-A8 MPU | NXP
MPN： SCIMX516AJM6CR2 ✗ 停產SCIMX516AJM6CR2 概覽
An MPU is an application processor that executes an operating system or embedded control software and integrates a CPU core with memory and peripheral interfaces. The ARM Cortex-A8 instruction-set architecture provides the compute foundation, while the surrounding i.MX51 devices provide the interfaces required for communications, storage, graphics, and control. Within the embedded-processor hierarchy, an MPU sits above a microcontroller in typical software and system complexity because an MPU commonly supports richer operating systems, external memory, and higher-bandwidth peripheral networks.
The verified listing describes SCIMX516AJM6CR2 as an i.MX51 32-bit MPU with an ARM Cortex-A8 core. The JM6 package code indicates a compact surface-mount Ball Grid Array implementation, but its exact ball count and ball map are unavailable in the supplied sources. Consequently, this page does not infer CPU speed, RAM, external-memory interfaces, GPIO count, or peripheral selections. Legacy i.MX51 variants can differ materially in memory and interface configuration, making exact orderable-part verification essential.
Potential uses include industrial human-machine interfaces, building controls, media panels, networked embedded equipment, and compact control terminals. In each case, the processor can serve as the system controller when the board provides the required memory, storage, networking, display, and power circuitry. Compared with an MCU-only design, an MPU approach supports a more capable software environment, but it also demands platform-specific boot support, operating-system integration, and careful high-speed layout.
Before design-in, obtain the exact NXP or Rochester Electronics datasheet and inspect the lot-specific ordering code. Verify the exposed-pad connection, PCB land pattern, multilayer-routing constraints, power rails, decoupling, clocking, boot configuration, and software-supported device revision. Do not reuse an i.MX6, i.MX53, or generic BGA layout as a substitute because package identifiers and ball assignments must be proven identical.
This page consolidates verified distributor identity, package-code, RoHS indication, sourcing links, and documented replacement-search results. Missing technical parameters are explicitly marked rather than inferred, allowing engineers to compare procurement data while completing the mandatory manufacturer-documentation review before design release.

典型應用
SCIMX516AJM6CR2 適用於 6 應用s: Industrial Human-Machine Interface, Building Automation Controller, Networked Media Control Terminal, Embedded Equipment Control Panel, Compact Data Acquisition System, Legacy Software Maintenance Platform.
Industrial Human-Machine Interface
SCIMX516AJM6CR2 can serve as the application processor in a compact operator panel because the verified i.MX51 identity places it in the embedded MPU class and the ARM Cortex-A8 core supports a more capable software environment than a basic MCU. The processor would manage the graphical interface, input handling, communications, and application logic. The JM6 6 mm x 6 mm MAPBGA also allows a dense board layout, but power delivery, memory routing, thermal performance, and exact LCD or Ethernet interfaces must be confirmed from the ordering-code datasheet before schematic capture.
Building Automation Controller
An i.MX51 Cortex-A8 MPU can fit a building-control node that coordinates lighting, HVAC, access, and sensor data under a real-time operating system. SCIMX516AJM6CR2 is appropriate only if its verified configuration includes the required serial, Ethernet, storage, and control interfaces. A compact controller benefits from the 6 mm x 6 mm BGA footprint, while the design must provide multiple clean power rails, careful BGA escape routing, watchdogs, boot support, and firmware recovery because the provided data does not specify the exact power or I/O configuration.
Networked Media Control Terminal
SCIMX516AJM6CR2 is architecturally suitable for a networked media terminal that combines local control, protocol handling, storage access, and user-interface software. The ARM Cortex-A8 core is the verified architectural identifier, while the specific Ethernet, display, USB, storage, and memory interfaces remain unavailable and must be checked in the exact datasheet. Engineers should evaluate boot media, Ethernet PHY support, audio routing, ESD protection, and operating-system drivers. The package's fine BGA geometry requires constrained fanout and assembly-process planning.
Embedded Equipment Control Panel
The SCIMX516AJM6CR2 can serve as the central controller in equipment that needs a graphical interface and higher-level embedded application software rather than a small deterministic MCU loop. Its verified 32-bit ARM Cortex-A8 core and i.MX51 MPU classification suit supervisory tasks, while the exact real-time I/O requirements should remain on suitable companion controllers if deterministic timing is critical. Design work must confirm available GPIO, timers, communications, memory, and boot functions from the exact orderable part, then partition tasks to avoid overloading the application processor.
Compact Data Acquisition System
SCIMX516AJM6CR2 may be used in a compact acquisition system when the i.MX51 device has the required external interfaces for sensors, storage, and communications. The application processor can collect data, timestamp events, run local filtering, and forward results over a network. Because verified data provides no ADC specifications, memory size, CPU frequency, or I/O map, sensor interfaces and precision converters must be added externally and checked against voltage, bandwidth, and timing requirements. The 6 mm x 6 mm MAPBGA also demands careful power integrity and thermal design.
Legacy Software Maintenance Platform
SCIMX516AJM6CR2 is most compelling for maintenance of an existing i.MX51 platform whose board, boot process, drivers, and application software are already proven. Retaining the processor can avoid PCB redesign and extensive operating-system porting while preserving field behavior. Engineers should nevertheless verify procurement traceability, exact package revision, security exposure, memory endurance, and long-term availability. A newer MPU should be selected if the existing platform lacks required performance or cannot be supplied reliably; migration should be treated as a complete hardware and software engineering effort.

設計說明
Treat the JM6 device as a fine-pitch MAPBGA and begin layout only after obtaining the exact package drawing. Verify ball count, pitch, ball map, exposed-pad requirements, solder-mask and paste rules, via-in-pad policy, and assembly tolerances. High-speed memory routing must use short, length-controlled paths with continuous return planes; do not derive the footprint from another i.MX51 or i.MX6 package based only on a similar nominal body size.
Confirm every supply rail, sequencing rule, current limit, and decoupling value from the exact ordering-code documentation. The supplied evidence does not provide voltage or current specifications, so generic i.MX rail values must not be assumed. Validate the regulator loop at the BGA, place local bulk and high-frequency decoupling according to manufacturer guidance, and use stitching vias where the package design calls for them. Review startup and power-off behavior before connecting sensitive external circuits.
Do not interpret the i.MX51 family name or JM6 package code as a complete orderable-device specification. Legacy variants can differ in CPU rate, memory, pin multiplexing, boot support, and peripheral availability. Before schematic release, compare the exact SCIMX516AJM6CR2 ordering code against the manufacturer product record, pin table, errata, exposed-pad connection, and supported software. This prevents a mechanically similar but electrically or software-incompatible part from entering the BOM.
