The RC oscillator and events includes many low-power modes. The resulting current management ensures fast start-up.

Therefore, a minimal constant inclusive buffer for current or voltage output current is delivered to the XE8000 even at maximum VDD • 120 segments (1-2-3-4 multiplex) LCD driver: voltage. A side advantage of the voltage regulator is that LCD lines can be used as additional I/O the maximal operation speed of the processor does not depend on the voltage supply. Therefore, the embedded CPU: software does not have to verify the voltage supply before ® The XE8000 series uses the CoolRISC processor core that going full speed. has a separate 22-bit instruction bus and 8-bit data bus. The reduced instruction set (35 generic instructions) includes Hibernating low-power mode: efficient multiplication instructions (8x8 bits in one cycle). Its The XE8000 can be completely halted. The oscillator and 3-stage pipeline allows execution of all instructions the Prescaler will still be running while in halt mode. In such (including conditional branches, multiplication, multiple a configuration, the CPU will awaken the XE8000 to perform position shifts, and set/test bit) in one clock cycle. housekeeping activities before going back to Halt mode. Data can be accessed through 8 powerful addressing Sleep mode: modes. Instructions are all on one single page (no need to When completely halted, and with disabled clocks, data swap pages). remain kept in the static RAM as long as the power supply voltage is sufficient, with nearly no current required (idle ® CoolRISC Instruction set: current near to 0.1 uA at 27 °C). Any reset condition will All instructions execute in one clock cycle wake up the CPU. JUMP, Jcondition, CALL, CALLS RET, RETS, RETI Events: PUSH, POP, MOVE In addition to the interrupts, the XE8000 also manages CMVD, CMVS events. The main advantage of the event over the interrupt SHL, SHLC, SHR, SHRC, SHRA is threefold: CPL1, CPL2, CPL2C • No stack-register saving is required INC, INCC, DEC, DECC • No latency as to interrupt routine AND, OR, XOR ADD, ADDC, SUBD, SUBDC, SUBS, SUBSC Low-power RAM: MUL, MULA, MSHL, MSHR, MSHRA Additional 8 bytes of ultra low-power RAM have been CMP, CMPA added in the peripherals.
