Feature List
32-bit Version 1 ColdFire central processor unit (CPU)
— Up to 50.33 MHz at 2.7 V – 5.5 V
— Provide 0.94 Dhrystone 2.1 DMIPS per MHz performance when running from internal RAM
(0.76 DMIPS per MHz when running from flash)
— Implements instruction set revision C (ISA_C)
On-chip memory
— Up to 256 KB flash memory read/program/erase over full operating voltage and temperature
— Up to 32 KB static random access memory (SRAM)
— Security circuitry to prevent unauthorized access to SRAM and flash contents
Power-Saving Modes
— Three low-power stop plus wait modes
— Peripheral clock enable register can disable clocks to unused modules, reducing currents;
allows clocks to remain enabled to specific peripherals in stop3 mode
System protection features
— Watchdog computer operating properly (COP) reset
— Low-voltage detection with reset or interrupt
— Illegal opcode and illegal address detection with programmable reset or exception response
— Flash block protection
Debug support
— Single-wire background debug interface
— Real-time debug support, with 6 hardware breakpoints (4 PC, 1 address pair and 1 data) that
can be configured into a 1- or 2-level trigger
— On-chip trace buffer provides programmable start/stop recording conditions plus support for
continuous or PC-profiling modes
— Support for real-time program (and optional partial data) trace using the debug visibility bus
V1 ColdFire interrupt controller (CF1_INTC)
— Support of 40 peripheral I/O interrupt requests plus seven software (one per level) interrupt
requests
— Fixed association between interrupt request source and level plus priority, up to two requests
can be remapped to the highest maskable level + priority
— Unique vector number for each interrupt source
— Support for service routine interrupt acknowledge (software IACK) read cycles for improved
system performance
Multipurpose clock generator (MCG)
— Oscillator (XOSC); loop-control Pierce oscillator; crystal or ceramic resonator range of 31.25
kHz to 38.4 kHz or 1 MHz to 16 MHz
— FLL/PLL controlled by internal or external reference
— Trimmable internal reference allows 0.2% resolution and 2% deviation
Analog-to-digital converter (ADC)
