NXP Semiconductors MCF5328CVM240

Overview

MCF5328CVM240 from Freescale Semiconductor is a 240 MHz ColdFire V3 RISC microprocessor in 256-pin MAPBGA (17 mm × 17 mm), featuring 16 KB unified write-back cache, 32 KB dual-ported SRAM, SDR/DDR SDRAM controller, USB 2.0 Host and OTG, Fast Ethernet Controller (FEC), and LCDC - deployed in industrial HMI and VoIP gateway systems.

For engineers reviewing the MCF5328CVM240 datasheet, MCF5328CVM240 pinout, MCF5328CVM240 application, or MCF5328CVM240 equivalent, key selection criteria include 256-MAPBGA package compatibility, 240 MHz core clock with ÷3 peripheral bus, EVDD/IVDD/SDVDD supply sequencing, and FlexCAN absence versus MCF5329CVM240.

Technical Context

The MCF5328CVM240 implements the ColdFire V3 core with EMAC, supports dynamic signal multiplexing across GPIO, FlexBus, SDRAM, FEC, LCDC, and USB interfaces, and uses dual voltage domains (EVDD for I/O, IVDD for core, SDVDD for memory) requiring controlled power-up ramp rates (<500 µs) to avoid ESD clamp conduction.

Its FlexBus operates at up to 80 MHz (core clock ÷3), SDRAM controller supports both SDR and DDR modes via DRAMSEL pin, and USB subsystem includes separate ULPI-capable OTG and Host PHYs with dedicated USB_VDD/USB_VSS rails and mandatory external RC filtering per Freescale's Figure 3.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MCF5328CVM240 core?

The MCF5328CVM240 core operates at a maximum frequency of 240 MHz, delivering up to 211 Dhrystone 2.1 MIPS. This speed is achieved using an internal Phase-Locked Loop (PLL) with configurable multiplication factors, and the peripheral bus runs at core clock ÷3 (up to 80 MHz). The MCF5328CVM240 datasheet specifies this rating over the full –40°C to +85°C industrial temperature range.

Does the MCF5328CVM240 support DDR SDRAM?

Yes, the MCF5328CVM240 supports both SDR and DDR SDRAM through its integrated SDRAM controller. Selection between modes is controlled by the DRAMSEL input pin (H12): asserted for SDR, negated for DDR. The controller generates all required DDR signals including SD_CKE, SD_CS0/1, SD_A[13:0], SD_D[31:0], and SD_DQS, with timing compliant to JEDEC standards per Section 5.7.2 of the MCF5329DS.

Is the MCF5328CVM240 pin-compatible with the MCF5329CVM240?

Yes, the MCF5328CVM240 is pin-compatible with the MCF5329CVM240 in the 256-MAPBGA package, sharing identical pinout (Figure 4), power domains, and mechanical dimensions. However, MCF5329CVM240 adds FlexCAN and UTMI+ ULPI functionality on shared pins (e.g., LCD_D16/D17 for CANRX/CANTX), so PCBs designed for MCF5328CVM240 can accept MCF5329CVM240 only if those functions remain unused or are software-configured.

What are the critical power supply sequencing requirements for the MCF5328CVM240?

The MCF5328CVM240 requires strict supply sequencing: IVDD must not lead EVDD or SDVDD by more than 0.4 V during power-up, and IVDD/PLLVDD must power down before EVDD/SDVDD. Rise/fall times must be slower than 500 µs to prevent conduction in internal ESD protection diodes. These constraints are defined in Section 3.3 of the MCF5329DS and apply identically to MCF5328CVM240.

Does the MCF5328CVM240 include a hardware cryptography accelerator?

No, the MCF5328CVM240 does not include hardware cryptography accelerators. That feature is exclusive to the MCF5329CVM240, as confirmed in Table 1 (MCF532x Family Configurations) of the MCF5329DS. The MCF5328CVM240 provides all other peripherals listed - including FEC, USB Host/OTG, LCDC, QSPI, and SDRAM controller - but relies on software-based cryptographic routines for security functions.
