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
