8-bit General Purpose Ultra-Low-End Market KA MCUs
RS08KA microcontrollers (MCUs) are general-purpose 8-bit devices for the ultra-low-end market. Featuring RS08 architecture, RS08KA devices are specifically crafted to be more efficient and cost effective for small memory size microcontrollers. The MC9RS08KA MCU is a general-purpose device that can be used in a wide variety of applications, including high-brightness light-emitting diodes (LEDs), lighting system controls, small handheld devices, toys, AC line voltage monitoring and simple logic, analog drivers and ASIC replacements. It’s ideal for transitioning from solid-state relays and switching systems to a full electronic solution.

Features
8-bit RS08 Central Processor Unit (CPU)
- Up to 10 MHz (bus frequency) RS08 CPU at 1.8 volts for 100 ns minimum instruction time
- Subset of HC08 instruction set with added BGND instruction
- Supports tiny/short address mode
- Index addressing scheme through memory mapped registers X and D[X] within the tiny address range
- 14 byte code-efficient RAM
- X and D[X] mapped within code-efficient tiny address space
- 16 byte code-efficient peripheral register space
- Page window
- Simplified interrupt mechanism
- Subroutine call/return mechanism
Integrated Third-Generation Flash
- Fast, byte-writable programming— up to 20 µs/byte
- Offers 1 KB write/erase cycles minimum over temperature
Flexible Clock Options
- Internal clock source module containing a frequency-locked loop (FLL) controlled by internal or external reference
- Precision trimming of internal reference allows typical 0.2 percent resolution and +1 percent to -1 percent deviation over operating temperature and voltage
- Internal reference clock can be trimmed from 31.25 kHz to 39.065 kHz, allowing for maxim 10 MHz Bus frequency output
Timer
- 2 x 8-bit modulo timer with 8-bit prescaler
- 2-ch., 16-bit timer/PWM
- Allows external timer clock source
ADC
- 12-ch., 10-bit resolution
- 2.5 µs conversion time; automatic compare function
- Trigger conversion using RTI counter
Analog Comparator
- Option to compare to internal reference
- Option to route comparator output directly to pin
- Allows operation in MCU STOP mode
I2C
- Inter-integrated circuit bus module capable of operation up to 100 kbps with maximum bus loading
Real-Time Interrupt
- Real-time interrupt trigger with 3-bit prescaler
- Built-in low-power 1 kHz clock source
Up to 18 GPIOs
- Software selectable pull-ups on ports when used as input (internal pull-up on RESET)
- Software selectable slew rate control on ports when used on output
- 8-pin keyboard interrupt module with software selectable polarity on edge or edge/level modes
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 and illegal address detection with reset
- Security feature for flash
Background Debugging System
- On-chip BDM
Package
- Pin-compatible with SH, QG family
