SC9RS08KA2 Features
8-Bit RS08 Central Processor Unit (CPU)
Simplified S08 instruction set with added high-performance instructions — LDA, STA, and CLR instructions support the short addressing mode; address $0000 to $001F can be accessed via a single-byte instruction — 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 — 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 — SC9RS08KA2: 2048 bytes — SC9RS08KA1: 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 — Trimmable 20-MHz internal clock source — Up to 10-MHz internal bus operation — 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 — 8-bit modulo timer ACMP — Analog comparator
— Full rail-to-rail supply operation — Option to compare to fixed internal
bandgap reference voltage — Can operate in stop mode KBI — Keyboard interrupt ports ...
