For engineers reviewing the MCF53017CMJ240J datasheet, MCF53017CMJ240J pinout, MCF53017CMJ240J application, or MCF53017CMJ240J equivalent, key selection criteria include MAPBGA-256 package compatibility, 240 MHz real-time deterministic performance, dual-FEC Ethernet interface timing, SDRAM controller support for DDR/SDR, and integrated CAU for AES/SHA-1 acceleration in edge security applications.

Technical Context

The MCF53017CMJ240J implements a Version 3 ColdFire core with EMAC and crossbar switch architecture enabling concurrent access to peripherals and SRAM by multiple bus masters. It integrates two independent Fast Ethernet Controllers (FECs) supporting both MII and RMII physical layer interfaces with full-duplex operation and IEEE 802.3 compliance.

Its memory subsystem includes a 16 KB unified instruction/data cache, 128 KB internal SRAM with standby power supply support, and a flexible SDRAM controller supporting 16-bit SDR, 16-bit DDR, and mobile-DDR configurations. The eSDHC supports CE-ATA, SDIO, MMC, and SD Combo cards at up to 50 MHz clock rates.

FAQ

What is the maximum operating frequency of the MCF53017CMJ240J?

The MCF53017CMJ240J operates at a maximum core frequency of 240 MHz, delivering up to 211 Dhrystone 2.1 MIPS performance. This frequency is achieved using an internal PLL with external crystal reference (EXTAL/XTAL), and the device supports dynamic clock gating and multiple low-power modes including Stop, Wait, and Doze to optimize energy efficiency in battery-backed or thermally constrained deployments of the MCF53017CMJ240J.

Does the MCF53017CMJ240J support DDR SDRAM?

Yes, the MCF53017CMJ240J includes a dedicated SDRAM controller supporting 16-bit DDR SDRAM in addition to SDR and mobile-DDR configurations. The controller complies with JEDEC standards and provides programmable timing parameters for CAS latency, tRCD, tRP, and refresh intervals. Validated DDR operation requires proper PCB layout for signal integrity and adherence to voltage domain separation rules between SDVDD (1.8 V or 2.5 V) and IVDD (1.2 V) as specified in the MCF53017CMJ240J datasheet.

What interfaces does the MCF53017CMJ240J provide for audio applications?

The MCF53017CMJ240J integrates a complete voice-band audio codec with differential ADC and DAC channels, plus four dedicated analog amplifiers: speaker, microphone, headphone, and handset. It supports standard audio sampling rates (8–48 kHz) and includes internal biasing, filtering, and AGC circuitry - eliminating the need for external codec ICs or op-amp networks in VoIP endpoints, intercom systems, or IP phone designs based on the MCF53017CMJ240J.

How many Ethernet MACs does the MCF53017CMJ240J include, and what PHY interfaces are supported?

The MCF53017CMJ240J includes two independent 10/100 Fast Ethernet Controllers (FEC0 and FEC1), each supporting both MII and RMII physical layer interfaces. RMII mode reduces pin count and simplifies board layout by using a shared 50 MHz reference clock and 2-bit data paths, while MII provides full 4-bit nibble-wide interface for legacy PHY compatibility - enabling dual-port routing, redundancy, or protocol isolation in networking applications built around the MCF53017CMJ240J.

Is the MCF53017CMJ240J pin-compatible with other members of the MCF5301x family?

Yes, the MCF53017CMJ240J shares identical 256-pin MAPBGA mechanical footprint and pinout with MCF53014CMJ240J, MCF53015CMJ240J, and MCF53016CMJ240J. All four variants use the same package dimensions (17 mm × 17 mm), ball pitch (1.0 mm), and signal mapping per Freescale's MCF5301x Data Sheet Rev. 5, Figure 7 - allowing drop-in replacement in PCB designs targeting different feature subsets within the same family, including the MCF53017CMJ240J.
