Description
R8C CPU core
• Number of fundamental instructions: 89
• Minimum instruction execution time:
31.25 ns (CPU clock = 32 MHz, VCC = 2.7 V to 5.5 V)
• Multiplier: 16 bits × 16 bits  32 bits
• Multiply-accumulate instruction: 16 bits × 16 bits + 32 bits  32 bits
• Operating mode: Single-chip mode (address space: 1 Mbyte)
Refer to Table 1.10 R8C/54F Group Product List.
• Power-on reset
• Voltage detection with three check points (the detection levels for voltage
detection 0 and voltage detection 1 can be selected.)
• Input only: 1
• CMOS I/O: 43, selectable pull-up resistor
• Peripheral mapping controller (PMC) allows communication function priority
pin assignment selection.
• 4 circuits: XIN clock oscillation circuit,
high-speed on-chip oscillator (with frequency adjustment function),
low-speed on-chip oscillator,
PLL frequency synthesizer (up to 32 MHz), multiplied by 2, 4, 6, or 8
• Oscillation stop detection: XIN clock oscillation stop detection function
• Frequency divider circuit: Divided by 1, 2, 4, 8, or 16 can be selected
• Low-power mode: Standard operating mode (high-speed clock, high-speed
on-chip oscillator, low-speed on-chip oscillator, PLL
operating), wait mode, stop mode
• Number of interrupt vectors: 69
• External interrupt inputs: 9 (INT × 5, key input × 4)
• Priority levels: 7
• Events output from peripheral functions can be linked to events input to
different peripheral functions.
(22 sources × 7 types of event link operations)
• Events can be handled independently from interrupt requests.
• 14 bits × 1 (with prescaler)
• Selectable reset start function
• Selectable low-speed on-chip oscillator for the watchdog timer
• 1 channel
• Activation sources: 36
• Transfer modes: 2 (normal mode, repeat mode)
