NXP USA Inc. MC9RS08KA4CWG

MC9RS08KA4CWG Description
The ultra-low-end market's general-purpose 8-bit hardware is the MC9RS08KA4CWG microcontroller (MCU). RS08KA devices, which use the RS08 architecture, were created especially for tiny memory size microcontrollers to be more effective and affordable. High-brightness light-emitting diodes (LEDs), lighting system controllers, compact handheld devices, toys, AC line voltage monitoring, simple logic, analog drivers, and ASIC replacements are just a few of the uses for the multipurpose MC9RS08KA MCU. It is perfect for making the changeover to a complete electronic solution from solid-state relays and switching systems.

MC9RS08KA4CWG Features
Clock Source Options
– Oscillator (XOSC) — Loop-Control Pierce oscillator; crystal or ceramic resonator range of 31.25 kHz to 39.0625 kHz or 1 MHz to 5 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 up 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 detection with reset or interrupt – Illegal opcode detection with reset – 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 8-Bit RS08 Central Processor Unit (CPU)
– Up to 20 MHz CPU at 1.8 V to 5.5 V across temperature range of –40°C to 85°C – Subset of HC08 instruction set with added BGND instruction On-Chip Memory
– 8 KB flash read/program/erase over full operating voltage and temperature; KA4 has 4 KB flash – 254 byte random-access memory (RAM); KA4 has 126 byte RAM – Security circuitry to prevent unauthorized access to RAM and flash contents Power-Saving Modes
– Wait and stop – Wakeup from power-saving modes using real-time interrupt (RTI), KBI, or ACMP
