NXP Semiconductors MCF53016CMJ240J

Overview

MCF53016CMJ240J from NXP Semiconductors (formerly Freescale) is a ColdFire® v3 microprocessor with integrated EMAC, 240 MHz core clock, 128 KB on-chip SRAM with standby power support, dual 10/100 Ethernet MACs, and eSDHC controller supporting SD/SDIO/MMC/CE-ATA. It targets VoIP gateways, industrial communication controllers, and secure network edge devices requiring real-time processing and cryptographic acceleration.

For engineers reviewing the MCF53016CMJ240J datasheet, MCF53016CMJ240J pinout, MCF53016CMJ240J application, or MCF53016CMJ240J equivalent, key selection criteria include MAPBGA-256 package compatibility, 240 MHz performance at –40°C to +85°C, dual FEC timing alignment, eSDHC card interface voltage tolerance (1.8 V / 3.3 V), and CAU-accelerated AES/SHA-1 execution latency.

Technical Context

The MCF53016CMJ240J implements a Version 3 ColdFire core with EMAC unit and crossbar switch (XBS) enabling concurrent access to peripherals and SRAM by multiple bus masters. Its memory subsystem includes 16 KB unified instruction/data cache and a flexible SDR/DDR/mobile-DDR SDRAM controller supporting 16-bit or 32-bit data paths.

Peripherals include two ISO7816 smart card interfaces, voice-band audio codec with integrated amplifiers, USB 2.0 On-the-Go and Host controllers, 3 UARTs, I²C, DSPI, SSI, RTC with standby support, and a 16-channel DMA controller. The CAU coprocessor accelerates DES, 3DES, AES, MD5, and SHA-1 operations independently of the main CPU.

Key Specifications

Supply support for MCF53016CMJ240J includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

NXP Semiconductors acquired Freescale in 2015 and maintains the ColdFire portfolio for industrial and networking applications demanding long-term availability and deterministic real-time performance.

The MCF5301x family was designed specifically for cost-sensitive, high-integration embedded networking and voice applications-emphasizing dual Ethernet, cryptographic acceleration, and integrated analog audio in a single MAPBGA package.

FAQ

What is the operating temperature range for the MCF53016CMJ240J?

The MCF53016CMJ240J is rated for industrial operation from –40°C to +85°C ambient temperature. This range is validated per Freescale's preliminary datasheet Rev. 5 and applies to all electrical specifications including core frequency (240 MHz), SRAM retention, and FEC timing margins. Thermal derating is not required within this envelope.

Does the MCF53016CMJ240J include a USB host controller?

No, the MCF53016CMJ240J does not include a USB host controller. It integrates only a USB 2.0 On-the-Go (OTG) controller. The USB host function is present in the pin-compatible MCF53017CMJ240J variant but omitted in MCF53016CMJ240J to reduce silicon area and power consumption.

What SDRAM types are supported by the MCF53016CMJ240J memory controller?

The MCF53016CMJ240J supports 16-bit or 32-bit SDR SDRAM, 16-bit DDR SDRAM, and 16-bit mobile-DDR SDRAM. It does not support LPDDR2 or DDR3. Configuration is via mode registers and timing parameters programmed in the SDRAM controller registers, with AC timing compliant to JEDEC standards for each type.

How is cryptographic acceleration implemented in the MCF53016CMJ240J?

Cryptographic acceleration in the MCF53016CMJ240J is handled by a dedicated Cryptography Acceleration Unit (CAU) coprocessor. It executes DES, 3DES, AES (128/192/256-bit), MD5, and SHA-1 algorithms in hardware, accessible via memory-mapped registers. The CAU operates independently of the ColdFire core, allowing concurrent crypto and application processing.

What is the function of the VSTBY_SRAM and VSTBY_RTC pins on the MCF53016CMJ240J?

VSTBY_SRAM supplies standby power to retain the 128 KB on-chip SRAM during Stop(3) mode (typical current draw 0.65 mA), while VSTBY_RTC powers the real-time clock module to maintain time-of-day across full system power cycles. Both pins must be connected to a dedicated low-quiescent-current 1.2 V supply to enable these low-power features.
