⢠32-Bit Version 1 ColdFire® Central Processor Unit (CPU)
â Up to 50.33-MHz ColdFire CPU from 3.6V to 2.1V, and
20-MHz CPU at 2.1V to 1.8V across temperature range
of -40°C to 85°C
â Provides 0.94 Dhrystone 2.1 MIPS per MHz
performance when running from internal RAM
(0.76 DMIPS/MHz from flash)
â Implements Instruction Set Revision C (ISA_C)
â Support for up to 30 peripheral interrupt requests and
seven software interrupts
⢠On-Chip Memory
â Flash read/program/erase over full operating voltage
and temperature
â Random-access memory (RAM)
â Security circuitry to prevent unauthorized access to
RAM and flash contents
⢠Power-Saving Modes
â Two low power stop modes; reduced power wait mode
â Peripheral clock enable register can disable clocks to
unused modules, reducing currents; allows clocks to
remain enabled to specific peripherals in stop3 mode
â Very low power external oscillator can be used in stop3
mode to provide accurate clock to active peripherals
â Very low power real time counter for use in run, wait,
and stop modes with internal and external clock sources
â 6 μs typical wake up time from stop modes
⢠Clock Source Options
â Oscillator (XOSC) â Loop-control Pierce oscillator;
Crystal or ceramic resonator range of 31.25 kHz to
38.4 kHz or 1 MHz to 16 MHz
â Internal Clock Source (ICS) â FLL controlled by
internal or external reference; precision trimming of
internal reference allows 0.2% resolution and 2%
deviation; supports CPU freq. from 2 to 50.33 MHz
⢠System Protection
â Watchdog computer operating properly (COP) reset
with option to run from dedicated 1-kHz internal clock
source or bus clock
â Low-voltage detection with reset or interrupt; selectable
trip points
â Illegal opcode and illegal address detection with
programmable reset or exception response
â Flash block protection

with programmable start/stop conditions
⢠ADC â 24-channel, 12-bit resolution; 2.5 μs conversion
time; automatic compare function; 1.7 mV/°C temperature
sensor; internal bandgap reference channel; operation in
stop3; fully functional from 3.6V to 1.8V
⢠ACMPx â Two analog comparators with selectable
interrupt on rising, falling, or either edge of comparator
output; compare option to fixed internal bandgap reference
voltage; outputs can be optionally routed to TPM module;
operation in stop3
⢠SCIx â Two SCIs with full duplex non-return to zero
(NRZ); LIN master extended break generation; LIN slave
extended break detection; wake up on active edge
⢠SPIxâ Two serial peripheral interfaces with Full-duplex or
single-wire bidirectional; Double-buffered transmit and
receive; MSB-first or LSB-first shifting
⢠IICx â Two IICs with; Up to 100 kbps with maximum bus
loading; Multi-master operation; Programmable slave
address; Interrupt driven byte-by-byte data transfer;
supports broadcast mode and 10 bit addressing
⢠TPMx â One 6-channel and two 3-channel; Selectable
input capture, output compare, or buffered edge- or
center-aligned PWMs on each channel
⢠RTC â 8-bit modulus counter with binary or decimal
based prescaler; External clock source for precise time
base, time-of-day, calendar or task scheduling functions;
Free running on-chip low power oscillator (1 kHz) for
cyclic wake-up without external components
⢠Input/Output
â 70 GPIOs and 1 input-only and 1 output-only pin
â 16 KBI interrupts with selectable polarity
â Hysteresis and configurable pull-up device on all input
pins; Configurable slew rate and drive strength on all
output pins.
â SET/CLR registers on 16 pins (PTC and PTE)
â 16 bits of Rapid GPIO connected to the CPUâs
high-speed local bus with set, clear, and toggle
functionality
