Product details
Overview
MCF5270CAB100 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microprocessor with integrated 10/100 Fast Ethernet MAC, 64 KB on-chip SRAM, 8 KB configurable instruction/data cache, and SDR SDRAM controller. It operates at 100 MHz (100 MIPS Dhrystone 2.1), supports industrial temperature range (–40°C to +85°C), and is packaged in a 160-pin QFP for embedded networking and industrial control applications.
For engineers reviewing the MCF5270CAB100 datasheet, MCF5270CAB100 pinout, MCF5270CAB100 application, or MCF5270CAB100 equivalent, key selection criteria include Ethernet MAC integration, SDRAM interface timing compliance, cold-temperature operation, QFP package layout compatibility, and ColdFire V2 core software ecosystem support.
Technical Context
The MCF5270CAB100 implements the ColdFire V2 core with enhanced multiply-accumulate (eMAC) unit and hardware divide, enabling deterministic real-time signal processing. Its memory subsystem includes a 32-bit SDR SDRAM controller supporting synchronous mode with SD_SRAS/SD_SCAS/SD_WE signals and byte-enable mapping via BS[3:0] to SDRAM DQM lines.
It integrates dual interrupt controllers (INTC0/INTC1), four 32-bit DMA timers, three UARTs, I²C, QSPI, and edge-port GPIO - all synchronized to a PLL-generated system clock. The FEC module supports both MII (18-signal) and 7-wire serial PHY interfaces, with pin multiplexing managed via PADI logic and CLKMOD[1:0] boot configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | ColdFire V2 32-bit RISC CPU with eMAC and hardware divide - enables cycle-predictable DSP-like operations without external coprocessor. |
| Max Clock Frequency | 100 MHz - delivers 100 MIPS (Dhrystone 2.1), sufficient for real-time protocol stacks (TCP/IP, Modbus TCP) on single-core execution. |
| On-Chip Memory | 64 KB SRAM + 8 KB configurable cache - eliminates need for external SRAM in many control applications; cache reduces bus contention during burst transfers. |
| Ethernet Interface | Integrated 10/100 Fast Ethernet MAC (FEC) - supports MII or 7-wire serial PHY connection; no external MAC required for basic network connectivity. |
| SDRAM Controller | 32-bit SDR SDRAM controller with synchronous mode - drives standard PC100/PC133 SDRAM; supports row/column address multiplexing and auto-refresh. |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including factory automation, remote telemetry, and outdoor infrastructure. |
| Package | 160-pin QFP (Case 864A-03), 28.0 mm × 28.0 mm - compatible with standard surface-mount assembly processes and manual rework; no BGA soldering complexity. |
Pinout & Package
Package: 160-pin Plastic Quad Flat Pack (QFP), Case No. 864A-03, body size 28.0 mm × 28.0 mm, lead pitch 0.65 mm. Pin 1 located at top-left corner (marked by notch or dot).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET | Active-low reset input | Asynchronous global reset; must be held low ≥ 200 ns after power stabilization to ensure proper ColdFire core initialization. |
| EXTAL / XTAL | Oscillator input / output | Accepts 4–50 MHz crystal or external clock; XTAL output drives crystal; internal oscillator circuit requires 12–22 pF load capacitance. |
| A[23:0] / D[31:0] | Address / data bus | 24-bit multiplexed address bus and 32-bit data bus - interfaces directly to external memory or peripherals without glue logic in most configurations. |
| CS[3:0] / OE / R/W | Chip select / output enable / read-write | Four dedicated chip selects plus OE/R/W control - enables direct connection to up to four independent memory-mapped devices (e.g., Flash, SDRAM, FPGA). |
| ETXCLK / ERXCLK | Ethernet transmit/receive clock | 25 MHz MII clock inputs - sourced externally in MII mode; used to synchronize FEC data transfers with external PHY device timing. |
| ERXD[3:0] / ETXD[3:0] | Ethernet receive/transmit data | 4-bit nibble-wide MII data paths - reduce PCB trace count vs. full 16-bit MII; require precise length matching (<5 mm skew) for 100 Mbps operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated FEC with MII/serial PHY support | Reduces BOM cost by eliminating discrete Ethernet MAC; 7-wire mode enables low-pin-count PHYs like LAN83C185 for space-constrained designs. |
| 32-bit SDR SDRAM controller | Supports up to 256 MB external memory with programmable timing registers - enables Linux-capable memory footprint without external memory controller ASIC. |
| Dual INTC with 64-vector prioritization | Enables deterministic interrupt latency down to 6 cycles - critical for hard real-time tasks such as motor commutation or packet forwarding. |
| QSPI and I²C peripherals | Allows direct connection to serial Flash (QSPI) and sensors/power monitors (I²C) - eliminates need for parallel interface glue logic or level shifters. |
| Pin multiplexing with GPIO default | All alternate-function pins default to GPIO on reset - simplifies bring-up and debug; avoids unintended peripheral activation during initialization. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF5271CAB100 | Includes hardware encryption engine (SKHA/RNGA/MDHA); identical pinout and core spec; same 160-QFP package. | Required for TLS/SSL offload or secure boot; adds ~150 mW active power; not needed for basic Ethernet routing. | Select when cryptographic acceleration is mandatory; otherwise MCF5270CAB100 offers lower cost and power for non-secure applications. |
| MCF5270CVM100 | Same core and peripherals but in 196-MAPBGA package; supports identical 100 MHz speed and –40°C to +85°C range. | Enables higher-density PCB layouts; requires BGA reflow and X-ray inspection; less suitable for prototyping or repair. | Choose for production volume where board area is constrained and BGA assembly capability exists; avoid for low-volume or field-serviceable designs. |
Compared with MCF5271CAB100, the MCF5270CAB100 omits hardware crypto but retains full Ethernet, SDRAM, and peripheral functionality - making it optimal for cost-sensitive industrial controllers where security is handled in software or external ICs. Versus MCF5270CVM100, the QFP package simplifies layout, debugging, and rework without sacrificing performance or temperature range.

FAQ
What is the maximum operating frequency of the MCF5270CAB100?
The MCF5270CAB100 is rated for a maximum system clock frequency of 100 MHz, delivering 100 MIPS (Dhrystone 2.1). This speed is guaranteed across the full industrial temperature range (–40°C to +85°C) and under specified supply voltage conditions (VDD = 1.5 V ± 3%, OVDD = 3.3 V ± 5%). Operation above 100 MHz is not supported and may result in timing violations or data corruption.
Does the MCF5270CAB100 include an integrated Ethernet MAC?
Yes, the MCF5270CAB100 integrates a full 10/100 Fast Ethernet MAC (FEC) compliant with IEEE 802.3. It supports both MII (18-signal interface) and a 7-wire serial PHY interface. The FEC does not include a physical layer (PHY); an external PHY IC (e.g., DP83848) must be used for copper or fiber media attachment.
What memory interfaces does the MCF5270CAB100 support?
The MCF5270CAB100 supports a 32-bit SDR SDRAM controller (with SD_SRAS/SD_SCAS/SD_WE and BS[3:0] signals), a 24-bit external memory interface (EMI) with four chip selects (CS[3:0]), and on-chip 64 KB SRAM + 8 KB cache. It does not support DDR, LPDDR, or NAND Flash controllers - those require external logic or companion ICs.
Is the MCF5270CAB100 pin-compatible with the MCF5271CAB100?
Yes, the MCF5270CAB100 and MCF5271CAB100 share identical 160-QFP pinouts, electrical characteristics, and core specifications. The only functional difference is that the MCF5271CAB100 includes hardware encryption modules (SKHA/RNGA/MDHA); all other peripherals, memory maps, and register sets are binary-compatible.
What development tools are supported for the MCF5270CAB100?
The MCF5270CAB100 is supported by CodeWarrior Development Studio for ColdFire v6.3+, GDB-based toolchains (e.g., GNU ColdFire GCC), and the M5271EVB evaluation board. Freescale's MQX Real-Time Operating System and open-source uClinux port provide validated software stacks. Debugging uses standard BDM/JTAG (IEEE 1149.1) via the PSTCLK/DSCLK/TMS/TDO/TDI pins.
