MCIMX257DJM4

The MCIMX257DJM4 is an i.MX25-series multimedia applications processor based on a single ARM926EJ-S core running at up to 400 MHz. Designed for embedded and industrial applications, the device combines processing performance with on-chip connectivity and advanced power management.

Its integration of memory controllers, Ethernet and USB PHYs, and display interfaces makes it suitable for compact, low-power embedded designs that require moderate CPU performance and multiple I/O options.

Key Features

• Core ARM926EJ-S 32-bit processor core running up to 400 MHz, providing deterministic embedded performance for control and user-interface tasks.
• Memory Controllers Integrated controllers for LPDDR, DDR and DDR2 memory types; datasheet support includes up to 133 MHz DDR2 operation for flexible memory subsystem choices.
• Connectivity Integrated 10/100 Mbps Ethernet MAC and two on-chip USB 2.0 controllers with PHYs, enabling wired networking and peripheral connectivity without external PHY components.
• Display and HMI Interfaces On-chip controllers for keypad, LCD and touchscreen interfaces to support human-machine interfaces and graphical remote controls.
• Power Management Advanced on-die power management features to minimize system power consumption across active and low-power modes, reducing overall energy use in battery or mains-powered designs.
• Package and Mounting Supplier device package: 400-LFBGA (17 × 17 mm) with 0.8 mm pitch; supplied in tray format and intended for surface-mount assembly.
• Qualification and Temperature Consumer qualification with an operating temperature range of −20°C to 70°C for general embedded and consumer product use.

Typical Applications

• Human-Machine Interfaces (HMI) Drives LCD and touchscreen-based HMIs for control panels and graphical remote controls using the on-chip display interfaces and touch support.
• Residential and Commercial Control Panels Integrates network connectivity and local HMI to support control and monitoring in residential or commercial systems.
• Gateways and Smart Metering Provides Ethernet and USB connectivity along with low-power operation suitable for residential gateway and smart metering applications.
• Point-of-Sale and Handheld Devices Supports handheld scanners, printers and point-of-sale terminals requiring moderate processing, display support and peripheral connectivity.
• Medical and Monitoring Equipment Applicable for patient-monitoring devices and similar consumer/industrial medical equipment that fit within the consumer qualification and temperature range.

Unique Advantages

• Highly integrated connectivity: Built-in 10/100 Ethernet MAC plus two USB 2.0 controllers with PHYs reduce external components and simplify board design.
• Flexible memory support: On-chip controllers for LPDDR, DDR and DDR2 (with support for up to 133 MHz DDR2) allow designers to choose memory types that match performance and cost targets.
• Optimized for low system power: Advanced power management features in the i.MX25 architecture minimize power consumption across active and low-power states.
• Compact BGA package: The 400-LFBGA (17 × 17 mm, 0.8 mm pitch) package enables high pin count in a compact, surface-mount form factor for space-constrained designs.
• Ready for embedded consumer products: Consumer qualification and common embedded interfaces make the device suitable for a wide range of industrial and general embedded applications.
