Product details
Overview
MCIMX253DJM4 from NXP Semiconductors (formerly Freescale) is an ARM926EJ-S-based multimedia applications processor operating at up to 400 MHz, featuring 128 KB on-chip SRAM, integrated 10/100 Ethernet MAC, dual USB PHYs (HS OTG + FS Host), and LCD controller with alpha blending. It targets industrial HMI, residential gateways, and handheld scanners requiring deterministic real-time response and low-power operation.
For engineers reviewing the MCIMX253DJM4 datasheet, MCIMX253DJM4 pinout, MCIMX253DJM4 application, or MCIMX253DJM4 equivalent, this page delivers verified technical context, validated package mapping, confirmed peripheral integration (eSDHC, CSI, UART×5, I²C×3), and precise thermal/electrical operating conditions for production-grade embedded design validation.
Technical Context
The MCIMX253DJM4 implements a single ARM926EJ-S core with 16 KB L1 instruction and 16 KB L1 data cache, executing in Little Endian mode only. Its memory subsystem supports DDR2 at up to 133 MHz via a dedicated External Memory Interface (EMI) with NAND, NOR, PSRAM, and SDRAM controllers.
Peripherals include a Smart DMA (SDMA) engine with 32 channels, two eSDHC controllers supporting SD/SDIO/MMC (up to 4-bit), five UARTs with IrDA-1.0 and 4 MHz max baud rate, and security modules including DryIce RTC/tamper detection and IIM fusebox for cryptographic key storage - all operating under a centralized Clock Control Module (CCM) managing wait/stop/doze power states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM926EJ-S, 400 MHz max - enables deterministic real-time execution for industrial control and HMI rendering without external co-processor. |
| On-chip Memory | 128 KB SRAM - eliminates need for external RAM in RTOS-based systems and enables ultra-low-power LCD refresh cycles. |
| Memory Interface | DDR2 @ 133 MHz, Mobile DDR, NAND/NOR/PSRAM/SDRAM support - allows flexible, cost-optimized BOM with single-chip memory management. |
| USB Integration | HS USB 2.0 OTG PHY + FS USB Host PHY - provides native device/host capability without external transceivers for peripheral connectivity. |
| Ethernet | 10/100 Mbps FEC compliant with IEEE 802.3 - delivers wired network interface with minimal external components (requires external PHY). |
| Security | DryIce RTC + tamper detection + IIM fusebox - enables secure boot, encrypted software updates, and POS terminal-level key protection. |
| Temperature Range | –20 °C to +70 °C - qualified for commercial-industrial environments including residential gateways and control panels. |
| Package | MAPBGA-400, 17 × 17 mm, 0.8 mm pitch - standard footprint compatible with automated PCB assembly and thermal vias for industrial thermal dissipation. |
Pinout & Package
MCIMX253DJM4 uses a 400-ball MAPBGA package (Case 5284), 17 mm × 17 mm, 0.8 mm pitch. Ball map follows Table 103 in IMX25CEC Rev. 10, with dedicated power/ground banks, configurable I/O banks (NVDD_GPIO1/NVDD_GPIO2), and signal groups routed per functional domain (EMI, USB, LCD, CSI).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BAT_VDD | DryIce backup supply input | Must be powered by coin cell (1.15–1.55 V) to retain RTC and secure keys during main power loss. |
| CLK0 | Configurable clock output / GPIO | Exposes internal clock for debug; muxable to GPIO when not used for timing verification. |
| CLK_SEL | ARM clock source select | Grounded to select MPLL as ARM clock source; floating or pulled high selects external EXT_ARMCLK. |
| OSC32K_EXTAL / OSC32K_XTAL | 32.768 kHz crystal interface | Analog pins for external crystal; configuration depends on OSC_BYP state - required for RTC and low-power timer accuracy. |
| USBPHY1_RREF | USB PHY1 reference current set | Requires external 10 kΩ ±1% resistor to GND to calibrate HS USB PHY bias current. |
| TAMPER_A / TAMPER_B | DryIce external tamper detect | Active-high inputs; tied to NVCC_DRYICE to trigger secure key erasure on physical intrusion detection. |
Key Features
| Feature | Design Value |
|---|---|
| Advanced Power Management | CCM-controlled wait/stop/doze modes reduce system power consumption while preserving peripheral context - critical for battery-backed HMIs and portable scanners. |
| Multimedia Acceleration | LCDC with alpha blending + CMOS image sensor interface (CSI) + programmable SDMA - enables local video overlay and touch-enabled UI rendering without GPU offload. |
| Interface Flexibility | Supports DDR2, NAND, NOR, PSRAM, SDRAM, and SRAM in same EMI controller - simplifies memory selection across product variants and lifecycle stages. |
| Secure Boot & Key Storage | IIM fusebox stores immutable chip identifiers and cryptographic keys; DryIce provides tamper-evident RTC - meets requirements for DRM, e-commerce, and medical device data integrity. |
| Integrated Connectivity | HS USB OTG + FS USB Host + 10/100 FEC + eSDHC×2 + UART×5 + I²C×3 - reduces external IC count for compact, cost-sensitive industrial edge nodes. |

FAQ
What is the maximum DDR2 speed supported by MCIMX253DJM4?
The MCIMX253DJM4 supports DDR2 memory at up to 133 MHz, as specified in the Electrical Characteristics section of the IMX25CEC datasheet Rev. 10. This corresponds to a 266 MT/s data rate in double-data-rate mode. The External Memory Interface (EMI) handles timing calibration and command scheduling, enabling reliable operation with standard DDR2-266 components without external logic.
Does MCIMX253DJM4 include an integrated USB PHY?
Yes, MCIMX253DJM4 integrates both a high-speed USB 2.0 OTG PHY and a full-speed USB host PHY. These are silicon-embedded analog blocks requiring only external 33 Ω series resistors on USBPHY2_DM/DP and a 10 kΩ resistor on USBPHY1_RREF - no external transceiver IC is needed for basic USB device or host functionality.
What is the purpose of the BAT_VDD pin on MCIMX253DJM4?
The BAT_VDD pin supplies backup power to the DryIce security module in MCIMX253DJM4. When main power fails, BAT_VDD (1.15–1.55 V from a coin cell) preserves the Real-Time Clock and secure cryptographic keys. This pin must be connected to a dedicated battery; tying it to QVDD invalidates tamper-resilient security features.
Can MCIMX253DJM4 operate in Big Endian mode?
No, MCIMX253DJM4 supports Little Endian mode only, as explicitly stated in the Features section of the IMX25CEC datasheet Rev. 10. The ARM926EJ-S core is configured at silicon level for Little Endian operation, and no runtime switch or configuration register enables Big Endian mode - software must be compiled accordingly.
What peripheral interfaces are included in MCIMX253DJM4 for touchscreen support?
MCIMX253DJM4 includes a dedicated Touchscreen Controller (TSC) with integrated 12-bit ADC, supporting 4-wire resistive touch panels. It provides simultaneous touch coordinate acquisition and auxiliary analog measurements (e.g., battery voltage, temperature), with configurable sampling rates and built-in debouncing - all managed without CPU intervention via SDMA transfers.
