The MCF537x devices are a family of highly-integrated 32-bit microprocessors based on the Version 3 ColdFire microarchitecture. All MCF537x devices contain a 32-Kbyte internal SRAM, a Fast Ethernet controller, a 2-bank SDR/DDR SDRAM controller, a 16-channel DMA controller, up to three UARTs, a queued SPI, as well as other peripherals that enable the MCF537x family for use in general purpose industrial control applications. Optional peripherals include USB host and On-the-Go controllers and cryptography hardware accelerators.
