32180 Group User’s Manual (Rev.1.0)
1.1 Outline of the 32180 Group
1.1.5 Built-in Clock Frequency Multiplier
• The 32180 contains a clock frequency multiplier, which is schematically shown in Figure 1.1.1 below.
XIN pin
(8MHz-10MHz)
BCLK (peripheral clock)
(16MHz-20MHz)
CPUCLK (CPU clock)
(64MHz-80MHz)

Functional Block
Features
CPUCLK
• CPU clock: Defined as f(CPUCLK) when it indicates the operating clock frequency for
the M32R-FPU core, internal flash memory and internal RAM.
BCLK
• Peripheral clock: Defined as f(BCLK) when it indicates the operating clock frequency
for the internal peripheral I/O and external data bus.
Clock output (BCLK pin output)
• A clock with the same frequency as f(BCLK) is output from this pin.
1.1.6 Powerful Peripheral Functions Built-in
(1) Multijunction timer (MJT)
(2) 10-channel DMAC
(3) Two 16-channel A-D converters (ADC)
(4) 6-channel high-speed serial I/O (SIO)
(5) Real-time debugger (RTD)
(6) 8-level interrupt controller (ICU)
(7) Three operation modes
(8) Wait controller
(9) 2-channel Full-CAN
(10) M32R family’s common debug function (Scalable Debug Interface or SDI)
