MC9RS08KB2CSC

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
• Flash-block protection
• Single-wire background debug interface
• Breakpoint capability to allow single breakpoint setting during in-circuit debugging
• One 2-channel Timer/pulse-width modulator module
• One real-time clock with optional clock sources
• up to 8-port Keyboard interrupts
