Overview of MCIMX257CJM4 – IC MPU I.MX25 400MHz 400-LFBGA
The MCIMX257CJM4 is an i.MX25-series applications processor featuring a single ARM926EJ-S 32-bit core running up to 400 MHz. It combines CPU performance with integrated peripherals and memory controller support to serve embedded and industrial designs.
Designed for human-machine interfaces and embedded control platforms, the device provides on-chip connectivity and power management features that reduce system complexity and support deployment in temperature-sensitive environments.
Key Features
- ARM926EJ-S 400 MHz core — Single 32-bit processor core operating up to 400 MHz for determinable embedded performance.
- Flexible memory controllers — On-chip controllers for LPDDR, DDR and DDR2; datasheet indicates support for DDR2 up to 133 MHz.
- Display and HMI interfaces — Integrated controllers for keypad, LCD and touchscreen connections to support user interfaces.
- Integrated connectivity — 10/100 Mbps Ethernet MAC and two USB 2.0 controllers with on-chip PHYs provide wired networking and host/device USB connectivity.
- Advanced power management — On-chip power management features enable reduced system power in active and various low-power modes (as described in the i.MX25 documentation).
- Compact BGA package — 400-LFBGA package (17 × 17 mm, 0.8 mm pitch) in a surface-mount tray format for space-constrained designs.
- Industrial-grade operation — Qualified for industrial use with an operating temperature range of −40 °C to 85 °C.
Typical Applications
- Graphical remote controls — Drives LCD and touchscreen interfaces while handling application logic and connectivity.
- Human machine interfaces (HMI) — Enables responsive display and keypad-driven interfaces in industrial and commercial panels.
- Residential and commercial control panels — Integrates processing, memory support, Ethernet and USB for connected control applications.
- Handheld scanners and printers — Provides embedded processing and peripheral interfaces suitable for portable data-capture devices.
- Point-of-sale and medical monitoring — Supports POS terminals and patient-monitoring devices with robust operating temperature range and integrated connectivity.
Unique Advantages
- Highly integrated connectivity: On-chip 10/100 Ethernet MAC plus two USB 2.0 controllers with PHYs reduce external component count and simplify board-level connectivity.
- Memory flexibility: Support for LPDDR, DDR and DDR2 (including DDR2 up to 133 MHz per datasheet) lets designers choose memory technologies to match performance and cost targets.
- Power-optimized operation: Documented power management features allow designers to minimize system power in both active and low-power modes.
- Industrial readiness: Industrial qualification and a −40 °C to 85 °C operating range make the device suitable for a wide range of embedded environments.
- Compact surface-mount package: The 400-LFBGA (17 × 17 mm, 0.8 mm pitch) package delivers a small-footprint solution for space-constrained systems.
