MCF5271 Integrated Microprocessor Hardware Specification, Rev. 1.2
Features
Freescale Semiconductor
6
— 24 to 50 MHz oscillator reference frequency for 1:1 mode
— Separate clock output pin
— Interrupt Controllers (x2)
– Support for up to 41 interrupt sources organized as follows: 34 fully-programmable
interrupt sources and 7 fixed-level external interrupt sources
— Unique vector number for each interrupt source
— Ability to mask any individual interrupt source or all interrupt sources (global mask-all)
— Support for hardware and software interrupt acknowledge (IACK) cycles
— Combinatorial path to provide wake-up from low power modes
DMA Controller
— Four fully programmable channels
— Dual-address and single-address transfer support with 8-, 16- and 32-bit data capability along
with support for 16-byte (4 x 32-bit) burst transfers
— Source/destination address pointers that can increment or remain constant
— 24-bit byte transfer counter per channel
— Auto-alignment transfers supported for efficient block movement
— Bursting and cycle steal support
— Software-programmable connections between the 12 DMA requesters in the UARTs (3),
32-bit timers (4), plus external logic (4), and the four DMA channels (4)
External Bus Interface
— Glueless connections to external memory devices (e.g., SRAM, Flash, ROM, etc.)
— SDRAM controller supports 8-, 16-, and 32-bit wide memory devices
— Support for n-1-1-1 burst fetches from page mode Flash
— Glueless interface to SRAM devices with or without byte strobe inputs
— Programmable wait state generator
— 32-bit bidirectional data bus
— 24-bit address bus
— Up to eight chip selects available
— Byte/write enables (byte strobes)
— Ability to boot from external memories that are 8, 16, or 32 bits wide
Chip Configuration Module (CCM)
— System configuration during reset
— Selects one of four clock modes
— Sets boot device and its data port width
— Configures output pad drive strength
— Unique part identification number and part revision number
