MCF5485CZP200

The NXP Semiconductors MCF5485CZP200 is a high-performance 32-bit microcontroller based on the ColdFire V4e core, capable of reaching peak internal frequencies of 200MHz. This device utilizes a Harvard architecture and includes a 32-Kbyte instruction cache and a 32-Kbyte data cache, along with a Memory Management Unit (MMU) and a Floating Point Unit (FPU) conforming to the IEEE-754 standard.

Key features include a 32-bit DDR SDRAM controller supporting 66–133 MHz operation, a Version 2.2 peripheral component interconnect (PCI) bus operating at 33–66 MHz, and a Flexible multi-function external bus (FlexBus) for glueless interfacing with memory and peripheral devices. The communications subsystem is robust, offering two 10/100 Mbps fast Ethernet controllers (FECs), a USB version 2.0 device controller, and up to four programmable serial controllers (PSCs) supporting various interfaces like UART, USART, and IrDA.

Additional integrated peripherals include two FlexCAN controllers, a DMA controller, and a system integration unit with an interrupt controller, watchdog timer, and multiple general-purpose timers. The MCF5485CZP200 is housed in a 388-PBGA (27x27 mm) package and is designed for surface mounting. It operates within a temperature range of -40°C to 85°C (TA) and requires operating voltages of 1.5V for internal logic, 2.5V for DDR SDRAM bus I/O, and 3.3V for PCI, FlexBus, and other I/O.
