MCF5206EFT54

Microprocessors Overview

The MCF5206EFT54 is an integrated microprocessor featuring a Version 2 ColdFire core with a Multiply-Accumulate (MAC) module and hardware divide unit. It includes a 4 KByte instruction cache, 8 KByte on-chip SRAM, a DRAM controller supporting EDO and page modes, and a 2-channel DMA controller. The device operates at 54 MHz, delivering 50 Dhrystone 2.1 MIPS, and supports fully static 3.3V operation with 5V tolerant inputs.

Microprocessors Feature Summary

• Version 2 ColdFire core enhanced with MAC and hardware divide for complex arithmetic
• Integrated memory subsystem including 4 KB I-cache, 8 KB SRAM, and DRAM controller
• Dual UARTs, dual 16-bit timers, and I2C-compatible bus system interface
• Pin-compatible upgrade path from the standard MCF5206

Microprocessors Applications

• Embedded control applications requiring DSP-like performance
• System integration tasks leveraging glueless interfaces to memory and I/O devices
• Upgrading existing designs based on the MC68K family

Microprocessors Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging status. Confirm the operating temperature range requirements match the datasheet specifications for the 54MHz frequency variant. Ensure compatibility with 3.3V logic levels and 5V tolerant input requirements for your target system design.

Microprocessors Selection Notes

Select this component when a cost-effective solution is needed that bridges the gap between legacy 68K architectures and modern embedded needs. It is suitable for designs requiring moderate processing power with integrated peripherals, minimizing external component count. Consider the pin-compatible upgrade path if migrating from the base MCF5206 model.

Microprocessors Part Context

This device belongs to the Motorola/Freescale ColdFire family of microprocessors. It serves as an enhanced version of the MCF5206, offering increased performance through higher clock speeds and additional integrated features like the MAC unit. It targets developers seeking a transition path from older 68K processors while maintaining software and toolchain familiarity.

Microprocessors Replacement Considerations

The MCF5206 is a direct pin-compatible predecessor. Verify if the lower performance or lack of MAC/hardware divide in the base model meets your application requirements before substituting.
