Product details
Overview
MCF5270AB100 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microprocessor with integrated Ethernet MAC, 64 KB on-chip SRAM, 8 KB configurable cache, and SDRAM controller. It operates at 100 MHz, delivers 96 Dhrystone 2.1 MIPS, and targets cost-sensitive industrial networking and embedded control applications requiring deterministic real-time performance.
For engineers reviewing the MCF5270AB100 datasheet, MCF5270AB100 pinout, MCF5270AB100 application, or MCF5270AB100 equivalent, key selection criteria include its 160-pin QFP package, 10/100 Mbps FEC interface, dual interrupt controllers, and support for external SDRAM with synchronous DRAM clock enable (SD_CKE) and row/column address strobes (SD_SRAS/SD_SCAS).
Technical Context
The MCF5270AB100 implements the ColdFire V2 core with enhanced multiply-accumulate (eMAC) unit and hardware divide, enabling efficient signal processing in motor control and protocol stacks. Its memory subsystem includes a 32-bit SDR SDRAM controller supporting multiplexed address/data buses and configurable burst lengths.
It integrates dual interrupt controllers (INTC0/INTC1), four DMA channels, three UARTs (with RTS/CTS flow control), I²C, QSPI, and edge-port module for GPIO expansion. The Fast Ethernet Controller supports both MII (18-signal) and seven-wire serial PHY interfaces, with pin-muxed EMDC/EMDIO for IEEE 802.3 management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF5271CAB100 | Includes hardware encryption engine (SKHA/RNGA/MDHA); identical pinout and core specs | Required for AES-128/SHA-1 acceleration in secure boot or TLS offload | Select when cryptographic acceleration is mandatory; otherwise MCF5270AB100 offers lower cost and same footprint |
| MCF52259AGB | Lower speed (64 MHz), smaller SRAM (32 KB), no FEC; uses 128-pin LQFP package | Suitable for non-networked control where Ethernet is unnecessary | Choose for cost-constrained, non-connected applications; not pin-compatible or drop-in replacement |
Compared with MCF5271CAB100, the MCF5270AB100 omits hardware crypto but retains full Ethernet, memory, and peripheral functionality-making it optimal for deterministic industrial networking without security acceleration. Versus MCF52259AGB, it delivers 56% higher MIPS and integrated FEC, justifying its use in connected edge nodes.

FAQ
What is the maximum operating frequency of the MCF5270AB100?
The MCF5270AB100 operates at a maximum frequency of 100 MHz, delivering 96 Dhrystone 2.1 MIPS. This speed is guaranteed across the commercial temperature range (0°C to +70°C) with proper power supply sequencing and decoupling. The MCF5270AB100 does not support overclocking beyond this rated frequency, and system timing must adhere to AC specifications in the MCF5271EC datasheet Rev. 4.
Does the MCF5270AB100 include hardware encryption capabilities?
No, the MCF5270AB100 does not include hardware encryption modules. Unlike the MCF5271 variant, it lacks the SKHA, RNGA, and MDHA cryptographic accelerators. For applications requiring AES or SHA acceleration, the MCF5271CAB100 is the functionally equivalent alternative with identical pinout and core specifications-but MCF5270AB100 remains optimal for non-secure Ethernet-enabled designs.
Which package type is used for the MCF5270AB100?
The MCF5270AB100 uses a 160-pin Quad Flat Package (QFP) with 0.65 mm pitch and 28.0 mm × 28.0 mm body dimensions. It is lead-free and RoHS compliant. This package is distinct from the 196-ball MAPBGA used in MCF5270VM100 and shares pin compatibility with other 160-QFP ColdFire variants like MCF5271CAB100.
Can the MCF5270AB100 interface directly with standard SDRAM chips?
Yes, the MCF5270AB100 includes a fully integrated 32-bit SDR SDRAM controller with dedicated signals including SD_SRAS, SD_SCAS, SD_WE, SD_CKE, and SD_CS[1:0]. It supports JEDEC-standard SDRAM devices with 1M×16, 2M×16, or 4M×16 organization, enabling up to 128 MB of external memory. Proper termination and layout per Section 5.7.1 of the MCF5271EC datasheet is required for reliable operation.
What are the power supply requirements for the MCF5270AB100?
The MCF5270AB100 requires three independent supplies: core VDD (1.5 V), I/O OVDD (3.3 V), and PLL VDDPLL (2.5 V). Power-up sequencing must ensure VDD and OVDD/VDDPLL track to 0.9 V before separating, with rise times slower than 1 µs. Violating voltage differentials (>0.4 V) between supplies risks ESD diode conduction and potential latch-up. Decoupling requires 33 µF bulk plus 0.1 µF and 0.01 µF ceramics per supply pin.
