MC9RS08KA2 Features
8-Bit RS08 Central Processor Unit (CPU)
⢠Simplified S08 instruction set with added
high-performance instructions
â LDA, STA, and CLR instructions
support the short addressing mode;
address $0000 to $001F can be
accessed via a single-byte instruction
â ADD, SUB, INC, and DEC instructions
support the tiny addressing mode;
address $0000 to $000F can be
accessed via a single-byte instruction
with reduced instruction cycle
â Shadow PC register instructions: SHA
and SLA
⢠Pending interrupt indication
⢠Index addressing via D[X] and X register
⢠Direct page access to the entire memory
map through paging window
Memory
⢠On-chip Flash EEPROM
â MC9RS08KA2: 2048 bytes
â MC9RS08KA1: 1024 bytes
⢠63 bytes on-chip RAM
Power-Saving Modes
⢠Wait and stop
⢠Wakeup from power-saving modes using
real-time interrupt (RTI), KBI, or ACMP
Clock Source
⢠ICS â Trimmable 20-MHz internal clock
source
â Up to 10-MHz internal bus operation
â 0.2% trimmable resolution, 2%
deviation over temperature and voltage
range
System Protection
⢠Computer operating properly (COP) reset
running off bus-independent clock source
⢠Low-voltage detection with reset or stop
wakeup
Peripherals
⢠MTIM â 8-bit modulo timer
⢠ACMP â Analog comparator
â Full rail-to-rail supply operation
â Option to compare to fixed internal
bandgap reference voltage
