NXP Semiconductors MCF5270VM100

Overview

MCF5270VM100 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 - operating at 100 MHz with 96 Dhrystone 2.1 MIPS, targeting cost-sensitive industrial networking and embedded control applications.

For engineers reviewing the MCF5270VM100 datasheet, MCF5270VM100 pinout, MCF5270VM100 application, or MCF5270VM100 equivalent, key selection criteria include its 196 MAPBGA package, dual interrupt controllers, hardware-accelerated eMAC unit, QSPI/I²C/UART interfaces, and absence of on-chip hardware encryption (distinguishing it from MCF5271).

Technical Context

The MCF5270VM100 implements the ColdFire V2 core with enhanced multiply-accumulate (eMAC) unit and hardware divide, supporting real-time deterministic execution in resource-constrained systems. It integrates a 32-bit SDR SDRAM controller with synchronous mode operation, configurable CS[3:0] and BS[3:0] signals, and SD_WE/SD_SCAS/SD_SRAS timing control.

Its external interface includes a 32-bit multiplexed data bus (D[31:0]), 24-bit address bus (A[23:0]), and dedicated FEC pins for MII or 7-wire serial PHY interfacing. Clock generation relies on an external crystal (EXTAL/XTAL) and internal PLL with CLKOUT buffer, while power domains separate VDD (core), OVDD (I/O), and VDDPLL (PLL) with strict sequencing requirements.

FAQ

What is the maximum operating frequency and performance rating of the MCF5270VM100?

The MCF5270VM100 operates at a maximum frequency of 100 MHz and delivers 96 Dhrystone 2.1 MIPS. This performance level is validated under industrial temperature conditions (0°C to +70°C) and assumes proper power supply sequencing and decoupling per Freescale's AN1259 layout guidelines. The ColdFire V2 core's eMAC unit further accelerates compute-intensive tasks beyond raw MIPS metrics.

Does the MCF5270VM100 include hardware encryption capabilities?

No, the MCF5270VM100 does not include hardware encryption modules. Unlike the MCF5271 variant, it lacks SKHA (Secure Key Hash Algorithm), RNGA (Random Number Generator), and MDHA (Message Digest Hash Algorithm) blocks. For applications requiring TLS/SSL acceleration or secure boot, the MCF5271CVM100 is the functionally equivalent alternative with identical pinout and memory architecture.

What package type and thermal characteristics apply to the MCF5270VM100?

The MCF5270VM100 uses a 196-ball MAPBGA package (case 1128A-01) with 15 mm × 15 mm footprint and exposed thermal pad. Its junction-to-ambient thermal resistance (θJMA) is 321°C/W under natural convection on a four-layer board, and maximum operating junction temperature is 104°C. Thermal design must ensure adequate copper pour under the thermal pad and follow Freescale's recommended via pattern per AN1259.

How does the MCF5270VM100 handle Ethernet PHY interfacing?

The MCF5270VM100 implements a full 10/100 Fast Ethernet MAC (FEC) supporting both MII (18-signal) and 7-wire serial modes. In MII mode, it drives ETXCLK, ETXEN, ETXD[3:0], ETXER, ERXCLK, ERXDV, ERXD[3:0], ERXER, ECOL, ECRS, EMDC, and EMDIO directly. Mode selection is controlled by R_CNTRL[MII_MODE]; no external PHY glue logic is required for standard MII-compliant transceivers.

What are the power supply requirements and sequencing constraints for the MCF5270VM100?

The MCF5270VM100 requires three independent supplies: VDD (1.5 V core), OVDD (3.3 V I/O), and VDDPLL (1.5 V PLL). During power-up, VDD and OVDD/VDDPLL must track to 0.9 V before separating; VDD must not exceed OVDD or VDDPLL by more than 0.4 V at any time. Rise times must be slower than 1 μs to prevent ESD diode conduction. Power-down follows the reverse sequence: VDD drops first, then OVDD/VDDPLL.
