The MC9RS08KB2CSC is a 8-bit Microcontroller based a very small and highly efficient RS08 CPU core of version 2 which supports single global interrupt vector with CISC architecture operates at a maximum frequency of 20MHz. The device is composed of standard on-chip modules including 126byte internal RAM, 2kB internal flash, two 8-bit modulo timers, one 4-channel 10-bit A/D converter and an analog comparator. This device also features peripherals like one serial communications interface (SCI) module and one inter-integrated circuit bus module (IIC).
Subset of HC08 instruction set with added BGND instruction
Single global interrupt vector
Security circuitry to prevent unauthorized access to flash contents
Wait mode - CPU shuts down, system clocks continue to run, full voltage regulation
Stop mode - CPU shuts down, system clocks are stopped, voltage regulator in standby
Wakeup from power-saving modes using RTI, KBI, ADC, ACMP, SCI and LVD
Loop-control Pierce oscillator (XOSC)
Internal clock source (ICS)
Watchdog computer operating properly (COP) reset
Low-voltage detection with reset or interrupt
Illegal opcode detection with reset
Illegal address detection with reset
