It supports up to 32 interrupt/reset sources and has on-chip memory including dual-array FLASH read/program/erase and random-access memory (RAM). The MC9S08LL16CGT also has power-saving modes, clock source options, system protection features, and development support. It offers 38 GPIOs, 2 output-only pins, and is available in different package options including 64-LQFP, 48-LQFP, and 48-QFN.

Specifications and features

• 8-bit HCS08 Central Processor Unit (CPU)
• Up to 20-MHz CPU at 3.6V to 1.8V across temperature range of -40°C to 85°C
• HC08 instruction set with added BGND instruction
• Support for up to 32 interrupt/reset sources
• Dual Array FLASH read/program/erase over full operating voltage and temperature
• Random-access memory (RAM)
• Security circuitry to prevent unauthorized access to RAM and FLASH contents
• Power-Saving Modes
• Two low power stop modes
• Reduced power wait mode
• Low power run and wait modes allow peripherals to run while voltage regulator is in standby
• Peripheral clock gating register can disable clocks to unused modules, thereby reducing currents
• Very low power external oscillator that can be used in stop2 or stop3 modes to provide accurate clock source to real time counter
• 6 usec typical wake up time from stop3 mode
• Clock Source Options
• Oscillator (XOSC) — Loop-control Pierce oscillator; Crystal or ceramic resonator range of 31.25 kHz to 38.4 kHz or 1 MHz to 16 MHz
• Internal Clock Source (ICS) — Internal clock source module containing a frequency-locked-loop (FLL) controlled by internal or external reference; precision trimming of internal reference allows 0.2% resolution and 2% deviation over temperature and voltage; supports bus frequencies from 1MHz to 10 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 Warning with interrupt
• Low-Voltage Detection with reset or interrupt
• Illegal opcode and illegal address detection with reset
• Flash block protection
• Development Support
• Single-wire background debug interface
• Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two more breakpoints in on-chip debug module)
• Input/Output
• 38 GPIOs, 2 output-only pins
• 8 KBI interrupts with selectable polarity
• Hysteresis and configurable pull up device on all input pins; Configurable slew rate and drive strength on all output pins
• Package Options
• 64-LQFP, 48-LQFP and 48-QFN
