NXP MC9RS08KA2CSC

RS0810 МГц2 КБ (2К x 8)

Overview

The MC9RS08KA2CSC is a 8-bit General-purpose Microcontroller based a very small and highly efficient RS08 CPU core with CISC architecture. The device is composed of standard on-chip modules including 63byte internal RAM, 2kB internal flash, an 8-bit modulo timer, five keyboard interrupt and analog comparator with full rail-to-rail supply operation.

Features

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

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

— MC9RS08KA2: 2048 bytes

• 63 bytes on-chip RAM

Applications

• Light sensing & controlling devices

• Temperature sensing and controlling devices

• Fire detection & safety devices

• Industrial instrumentation devices

• Process control devices
