特性 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
