Features
8-Bit HCS08 Central Processor Unit (CPU)
• 40-MHz HCS08 CPU (central processor unit)
• 20-MHz internal bus frequency
• HC08 instruction set with added BGND instruction
• Single-wire background debug mode interface
• Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two more breakpoints in on-chip debug module)
• On-chip real-time in-circuit emulation (ICE) with two comparators (plus one in BDM), nine trigger modes, and on-chip bus capture buffer. Typically shows approximately 50 instructions before or after the trigger point.
• Support for up to 32 interrupt/reset sources
Memory Options
• Up to 60 KB of on-chip in-circuit programmable FLASH memory with block protection and security options
• Up to 2 KB of on-chip RAM
Clock Source Options
• Clock source options include crystal, resonator, external clock, or internally generated clock with precision NVM trimming
System Protection
• Optional computer operating properly (COP) reset
• Low-voltage detection with reset or interrupt
• Illegal opcode detection with reset
• Illegal address detection with reset (some devices don’t have illegal addresses)
Power-Saving Modes
• Wait plus two stops
Peripherals
• ADC — Up to 16-channel, 10-bit analog-to-digital converter with automatic compare function
• SCI — Two serial communications interface modules with optional 13-bit break
• SPI — Serial peripheral interface module
• IIC — Inter-integrated circuit bus module to operate at up to 100 kbps with maximum bus loading; capable of higher baud rates with reduced loading
• Timers — One 2-channel and one 6-channel 16-bit timer/pulse-width modulator (TPM) module: Selectable input capture, output compare, and edge-aligned PWM capability on each channel. Each timer module may be configured for buffered, centered PWM (CPWM) on all channels
• KBI — Up to 8-pin keyboard interrupt module
Input/Output
• Up to 54 general-purpose input/output (I/O) pins
• Software-selectable pullups on ports when used as inputs
• Software-selectable slew rate control on ports when used as outputs
• Software-selectable drive strength on ports when used as outputs
• Master reset pin and power-on reset (POR)
• Internal pullup on RESET, IRQ, and BKGD/MS pins to reduce customer system cost
