MC9RS08KA4CWJ

Key features

• Simplified S08 instruction set with added high-performance instructions
• LDA, STA, and CLR instructions support the short addressing mode; address S0000 to S001F can be accessed via a single-byte instruction
• ADD, SUB, INC, and DEC instructions support the tiny addressing mode; address S0000 to S000F 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
• On-chip Flash EEPROM MC9RS08KA2: 2048 bytes, MC9RS08KA1: 1024 bytes
• 63 bytes on-chip RAM
• Wait and stop
• Wakeup from power-saving modes using real-time interrupt (RTI), KBI, or ACMP
• ICS — Trimmable 20-MHz internal clock source
• Up to 10-MHz internal bus operation
