Description
CPU CPU • Maximum operating frequency: 100 MHz
• 32-bit RX CPU
• Minimum instruction execution time: One instruction in one state (in one system clock
cycle)
• Address space: 4-Gbyte linear address
• Register set of the CPU
General purpose: Sixteen 32-bit registers
Control: Nine 32-bit registers
Accumulator: One 64-bit register

Memory Flash • Flash capacity: 2 Mbytes (max.)
• Three types of on-board programming modes
SCI boot mode, user program mode, and user boot mode
RAM RAM capacity: 128 Kbytes
Data flash
Data flash capacity: 32 Kbytes
MCU operating modes Single-chip mode, on-chip ROM enabled extended mode, and on-chip ROM disabled
extended mode
Clock Clock generation circuit • One main clock oscillation circuit
• Includes a PLL circuit and frequency divider, so the operating frequency is selectable
• System clock, peripheral module clock, and external bus clock are independently
specifiable.
The CPU, DMAC, DTC, ROM, and RAM run in synchronization with the system
clock (ICLK): 8 to 100 MHz
Peripheral modules run in synchronization with the peripheral module
clock (PCLK): 8 to 50 MHz
Devices connected to the external bus run in synchronization with the external bus
clock (BCLK): 8 to 25 MHz
Power down Power-down function • Module stop function
• Four power-down modes
Sleep mode, all-module clock stop mode, software standby mode, and deep software
standby mode
