An Energy-Efficient Solution from Freescale
32-Bit ColdFire V1 Central Processor Unit (CPU)
Up to 50.33-MHz ColdFire CPU above 2.4 V and 40 MHz CPU above
2.1 V and 20 MHz CPU above 1.8 V across temperature range of -40°C to
105°C.
ColdFire Instruction Set Revision C (ISA_C).
32-bit multiply and accumulate (MAC) supports signed or unsigned integer
or signed fractional inputs.
On-Chip Memory
256 K Flash comprised of two independent 128 K flash arrays;
read/program/erase over full operating voltage and temperature; allows
interrupt processing while programming.
32 Kbytes System Random-access memory (RAM).
Security circuitry to prevent unauthorized access to RAM and Flash
contents.
Power-Saving Modes
Two ultra-low power stop modes. Peripheral clock enable register can
disable clocks to unused modules to reduce currents.
Time of Day (TOD) — Ultra low-power 1/4 sec counter with up to 64s
timeout.
Ultra-low power external oscillator that can be used in stop modes to
provide accurate clock source to the TOD. 6 usec typical wake up time
from stop3 mode.
Clock Source Options
Oscillator (XOSC1) — Loop-control Pierce oscillator; 32.768 kHz crystal or
ceramic resonator dedicated for TOD operation.
Oscillator (XOSC2) for high frequency crystal input for MCG reference to
be used for system clock and USB operations.
Multipurpose Clock Generator (MCG) — PLL and FLL; precision trimming
of internal reference allows 0.2% resolution and 2% deviation over
temperature and voltage; supports CPU frequencies from 4 kHz to
50 MHz.
System Protection
Watchdog computer operating properly (COP) reset with option to run from
dedicated 1 kHz internal clock source or bus clock.
Low-voltage detection with reset or interrupt; selectable trip points;
separate low voltage warning with optional interrupt; selectable trip points.
Illegal opcode and illegal address detection with reset.
Flash block protection for each array to prevent accidental write/erasure.
Hardware CRC to support fast cyclic redundancy checks.
Development Support
Integrated ColdFire DEBUG_Rev_B+ interface with single wire BDM
connection supports same electrical interface used by the S08 family
debug modules.
Real-time debug with 6 hardware breakpoints (4 PC, 1 address and 1
data).
On-chip trace buffer provides programmable start/stop recording
conditions.
Peripherals
USB — Dual-role USB On-The-Go (OTG) device, supports USB in either
device, host or OTG configuration. On-chip transceiver and 3.3V regulator
help save system cost, fully compliant with USB Specification 2.0. Allows
control, bulk, interrupt and isochronous transfers.
SCIx — Two serial communications interfaces with optional 13-bit break;
option to connect Rx input to PRACMP output on SCI1 and SCI2; High
current drive on Tx on SCI1 and SCI2; wake-up from stop3 on Rx edge.
SPI1 — Serial peripheral interface with 64-bit FIFO buffer; 16-bit or 8-bit
data transfers; full-duplex or single-wire bidirectional; double-buffered
transmit and receive; master or slave mode; MSB-first or LSB-first shifting.
SPI2 — Serial peripheral interface with full-duplex or single-wire
bidirectional; Double-buffered transmit and receive; Master or Slave
mode; MSB-first or LSB-first shifting.
IIC — 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 11-bit addressing.
CMT — Carrier Modulator timer for remote control communications.
Carrier generator, modulator and driver for dedicated infrared out (IRO).
Can be used as an output compare timer.
TPMx — Two 4-channel Timer/PWM Module; Selectable input capture,
output compare, or buffered edge- or center-aligned PWM on each
channel; external clock input/pulse accumulator.
Mini-FlexBus — Multi-function external bus interface with user
programmable chip selects and the option to multiplex address and data
lines.
PRACMP — Analog comparator with selectable interrupt; compare option
to programmable internal reference voltage; operation in stop3.
ADC12 — 12-bit Successive approximation ADC with 4 differnential
channels and up to12 single-ended channels; internal bandgap reference
channel; operation in stop3; fully functional from 3.6V to 1.8V.
PDB — Programmable delay block with 16-bit counter and modulus and
prescale to set reference clock to bus divided by 1 to bus divided by 2048;
8 trigger outputs for ADC module provides periodic coordination of ADC
sampling sequence with sequence completion interrupt; Back-to-Back
mode and Timed mode.
DAC — 12-bit resolution; 16-word data buffers with configurable
watermark.
Input/Output
Up to 68 GPIOs and 1 output-only pin.
Voltage Reference output (VREFO).
Dedicated infrared output pinwith high current
sink capability.
Up to 16 KBI pins with selectable polarity.
Up to 16 pins of rapid general purpose I/O.
