Features

8-bit HCS08 CPU Core

  • Low-power technology
    • Multiple power management modes including 100 nA powerdown
    • Optional autowake-up from Stop 2 or Stop 3 modes with internal timer that typically requires only 300 nA additional current
    • 1.8V operation
  • High performance when needed
    • 125 µs minimum instruction cycle time down to 1.8V at 8 MHz bus
  • C-optimized architecture with multiply and divide instructions

On-Chip Debug Interface

  • Single-wire background debug module (BDM)
  • On-chip trace buffer with nine flexible trigger modes and multiple hardware breakpoints
  • Nonintrusive emulation

Integrated Third-Generation Flash Memory

  • In-application reprogrammable
    • Self-timed, fast programming
    • Fast Flash page erase: 20 µs (512B)
  • Can program 8 bits in 20 µs while in burst mode
  • 10K write/erase cycles minimum (100K typical)
  • 15-year minimum data retention; 100 years typical
  • Internal program/erase voltage generation
  • Flash granularity: 512B Flash erase/ 2B Flash program
  • Flexible block protection and security

Carrier Modulation Timer

  • Consists of a carrier generator, modulator and transmitter, which generate infrared pulses

Timer with Two Programmable Channels

  • Each channel programmable for
    • Input capture, output compare or buffered pulse-width modulation (PWM)
    • PWM can be edge- or center-aligned

Up to two Serial Communications Interfaces

  • One asynchronous serial communications interface (SCI)
    • Flexible 13-bit modulo-based baud rate generator
    • Double-buffered receive and transmit

Analog Comparator

  • Full rail-to-rail supply operation
  • Selectable interrupt on rising edge, falling edge, or either rising or falling edge of comparator output
  • Option to compare unknown input to a fixed internal bandgap reference voltage or external user-supplied reference

System Protection

  • Selectable low-voltage detect/reset at nominal 1.8V
  • Low-battery warning
  • Computer operating properly (COP) watchdog timer

Up to 39 Input/Output (I/O) Lines

  • Programmable pull-ups
  • High-current drivers
  • Eight keyboard interrupts

Part numbers include: MC9S08RE16FJE, MC9S08RG32CFJE, MC9S08RG32FGE.
