8-bit General Purpose Ultra-Low-End Market KA MCUs

RS08KA
正常供应

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
