8-bit Fact Sheet
Features
Benefits
Peripherals
• Analog-to-digital converter (ADC)—10-channel,
12-bit resolution; 2.5 µs conversion time; automatic
compare function; internal temperature sensor;
internal bandgap reference channel; operation
in stop mode
• Timer—two 3-channel (TPM1 and TPM2);
selectable input capture, output compare, or
buffered edge- or center-aligned PWM on each
channel
• Serial Communications Interface (SCI)—module
offering asynchronous communications,13-bit break
option, flexible baud rate generator, double buffered
transmit and receive and optional H/W parity
checking and generation
• Two analog comparators with option to compare
to an internal reference—output can be optionally
routed to timer/pulse width modulator (PWM) as
input capture trigger
• Serial Peripheral Interface (SPI)—one module
with full-duplex or single-wire bidirectional;
double-buffered transmit and receive; master
or slave mode; MSB-first or LSB-first shifting
• I²C 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
Input/Output
• Having 10 channels allows up to 10 analog
devices to be sampled at extremely high speeds
• Accuracy and full functionality guaranteed across
1.8V to 3.6V operating voltage of the MCU
• Two TPMs allow for two different time bases,
with a total of twelve timer channels
• Provides standard UART communications peripheral
• Allows full-duplex, asynchronous, NRZ serial
communication between MCU and remote devices
• Edge interrupt can wake up MCU from
low-power mode
• Requires only single pin for input signal, freeing
additional pins for other use
• Allows other components in system to see result
of comparator with minimal delay
• Can be used for single slope ADC and RC time
constant measurements
• Allows high speed (up to 5 Mbps) communications
to other MCUs or peripherals such as MC1319x
RF transceivers
• I²C port enables increased system memory by
using an additional I²C EEPROM. This also creates
an opportunity to add an additional I²C device.
• 27 General Purpose Input/Output (GPIO),
one input-only and one output-only pin
• Results in large number of flexible I/O pins that allow
developers to easily interface device into their
own designs
• 8 Keyboard Interrupts (KBI) pins with
selectable polarity
• Can be used for reading input from a keypad or
used as general pin interrupts
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
• Illegal op code and illegal address detection
with reset
• Flash block protection
Development Support
• Single-wire background debug interface
• Breakpoint capability
• ICE debug module containing three comparators
and nine trigger modes. Eight deep FIFO for
storing change-of-flow addresses and event-only
data—debug module supports both tag and
force breakpoints.
• Allows device to recognize runaway code
(infinite loops) and resets processor to avoid
lock-up states
• Alarms the developer of voltage drops outside
of the typical operating range
• Allows the device to recognize erroneous code
and resets the processor to avoid lock-up states
• Prevents unintentional programming of protected
flash memory, which greatly reduces the chance of
losing vital system code for vendor applications
• Allows developers to use the same hardware
cables between S08 and V1 ColdFire^® platforms
• Allows single breakpoint setting during in-circuit
debugging (plus three more breakpoints in on-chip
debug module)
• Provides built-in full emulation without expense of
traditional emulator
