NXP Semiconductors MCF5373LCVM240

Overview

MCF5373LCVM240 from Freescale Semiconductor is a ColdFire V3 RISC microprocessor with 240 MHz core clock, 32-Kbyte dual-ported SRAM, SDR/DDR SDRAM controller, USB 2.0 Host and OTG controllers, Fast Ethernet Controller (FEC), and cryptography hardware accelerators - deployed in embedded VoIP gateways requiring real-time packet processing, secure media transport, and multi-interface connectivity.

For engineers reviewing the MCF5373LCVM240 datasheet, MCF5373LCVM240 pinout, MCF5373LCVM240 application, or MCF5373LCVM240 equivalent, key selection criteria include MAPBGA-196 package compatibility, 240 MHz core performance, EVDD/SDVDD/IVDD voltage domain separation, FlexCAN absence (vs. MCF53721), and USB OTG + FEC coexistence in single-chip VoIP system solutions.

Technical Context

The MCF5373LCVM240 implements a ColdFire Version 3 core with EMAC unit, operating at up to 240 MHz core clock and 80 MHz peripheral bus clock (core ÷ 3). It integrates dual interrupt controllers (INTC0/INTC1), a 16-channel DMA controller, and a Phase-Locked Loop (PLL) with dedicated PLLVDD/PLLVSS power domains requiring external RC filtering per Figure 2 of the datasheet.

Its memory subsystem includes 16-Kbyte unified write-back cache and 32-Kbyte dual-ported SRAM accessible by CPU and bus masters (DMA, FEC, USB). The SDR/DDR SDRAM controller supports dynamic mode switching via DRAMSEL pin, while USB OTG and Host PHYs share dedicated USBVDD/USBVSS rails with mandatory external decoupling per Figure 3.

FAQ

What is the maximum operating frequency of the MCF5373LCVM240 core?

The MCF5373LCVM240 features a ColdFire V3 core rated for up to 240 MHz operation, delivering 211 Dhrystone 2.1 MIPS performance. This frequency is achieved using an internal PLL driven by an external crystal (25–50 MHz) applied to the EXTAL/XTAL pins, with IVDD regulated to 1.4–1.6 V. The MCF5373LCVM240 datasheet specifies this speed grade exclusively for the 196 MAPBGA package variant.

Does the MCF5373LCVM240 support DDR SDRAM memory?

Yes, the MCF5373LCVM240 includes an integrated SDR/DDR SDRAM controller capable of driving both SDR and DDR memory types. Mode selection is controlled by the DRAMSEL pin: asserted for SDR mode, negated for DDR mode. The controller supports standard DDR timing parameters and interfaces directly to SD_A[13:0], SD_D[31:0], SD_CKE, SD_CS0, and SD_CLK pins on the 196 MAPBGA package.

Is FlexCAN available on the MCF5373LCVM240?

No, FlexCAN 2.0B is not implemented in the MCF5373LCVM240. According to Table 1 of the MCF537x Family Configurations datasheet, FlexCAN is only present on the MCF53721 derivative. The MCF5373LCVM240 retains all other peripherals - including FEC, USB Host/OTG, SSI, I²C, QSPI, and three UARTs - but omits CAN functionality entirely.

What power supply sequencing is required for reliable startup of the MCF5373LCVM240?

The MCF5373LCVM240 requires strict supply sequencing: IVDD must not lead EVDD or SDVDD by more than 0.4 V during power-up, nor lag them by more than 0.4 V during power-down. Violation risks high current through internal ESD protection diodes. Recommended sequence is simultaneous ramp of EVDD/SDVDD followed by IVDD/PLLVDD within 0.4 V tolerance, with rise/fall times slower than 500 µs.

How many UART interfaces does the MCF5373LCVM240 provide, and what are their pin assignments?

The MCF5373LCVM240 provides three UART interfaces. UART0 uses pins U0RXD/U0TXD/U0RTS/U0CTS (balls P14/N14/M13/M14); UART1 uses U1RXD/U1TXD/U1RTS/U1CTS (balls B7/A7/D6/C6); UART2 signals are multiplexed onto QSPI and timer pins (e.g., QSPI_DIN/QSPI_DOUT for RX/TX). All UARTs operate at EVDD voltage domain and support programmable baud rates up to 3 Mbps.
