MC9S08MP16VLF Description
The 8-bit microcontroller architecture is simpler and has an easy to understand programming model. It usually needs just a single supply. Despite marketing claims to the contrary, modern 8-bit architectures are lower power compared to 32-bit because the innards toggle fewer bus signals.
MC9S08MP16VLF Features
? 8-Bit HCS08 Central Processor Unit (CPU)
– Up to 51.34 MHz CPU at 2.7V to 5.5V across temperature
range of –40°C to 105°C
– Up to 40 MHz CPU at 2.7V to 5.5V across temperature range
of –40°C to 125°C
– HC08 instruction set with added BGND instruction and
additional addressing modes for LDHX and STHX
– Support for up to 48 interrupt/reset sources
? On-Chip Memory
– Up to 16 KB flash memory; read/program/erase over full
operating voltage and temperature
– Up to 1 KB random-access memory (RAM)
– Security circuitry to prevent unauthorized access to RAM and
flash memory contents
? Power-Saving Modes
– Two low power stop modes; reduced power wait mode
– Peripheral clock gating can disable clocks to unused modules
? Clock Source Options
– Oscillator (XOSC) — Loop-control Pierce oscillator; Crystal
or ceramic resonator range of 31.25–38.4 kHz or 1–16 MHz
– Internal Clock Source (ICS) — Containing a
frequency-locked-loop (FLL) controlled by internal or
external reference; precision trimming of internal reference
allows 0.2% resolutions and 2% deviation over temperature
and voltage; supports CPU frequencies up to 51.34 MHz
? System Protection
– Watchdog computer operating properly (COP) reset running
from dedicated 1-kHz internal clock source or bus clock
– Low-voltage detection with reset or interrupt; selectable trip
points
– Illegal opcode and illegal address detection with reset
– Flash memory block protection
? Development Support
– Single-wire background debug interface
– Breakpoint capability to allow single breakpoint setting during
in-circuit debugging (plus three more breakpoints in on-chip
debug module)
– On-chip in-circuit emulator (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
? Peripherals
– IPC — Interrupt Priority Controller with 4 programmable
interrupt priority levels
– ADC — 13-channel, 12-bit resolution; 2.5 ms conversion time;
automatic compare function; 1.7 mV/°C temperature sensor;
internal bandgap reference channel; operation in stop3
