RX63N Group, RX631 Group 1. Overview
1. Overview
1.1 Outline of Specifications
Table 1.1 lists the specifications in outline, and table 1.2 gives a comparison of the functions of products in different
packages.
Table 1.1 is for products with the greatest number of functions, so numbers of peripheral modules and channels will
differ in accord with the package. For details, see Table 1.2, Comparison of Functions for Different Packages in the
RX63N/RX631 Group.

Clock Clock generation
circuit
 Main clock oscillator, subclock oscillator, low-speed/high-speed on-chip oscillator, PLL
frequency synthesizer, and IWDT-dedicated on-chip oscillator
 Main-clock oscillation stoppage detection
 Separate frequency-division and multiplication settings for the system clock (ICLK),
peripheral module clock (PCLK), FlashIF clock (FCLK) and external bus clock (BCLK)
The CPU and other bus masters run in synchronization with the system clock (ICLK):
Up to 100 MHz
Peripheral modules run in synchronization with the peripheral module clock (PCLK):
Up to 50 MHz
Flash IF run in synchronization with the flashIF clock (FCLK): Up to 50 MHz
Devices connected to the external bus run in synchronization with the external bus clock
(BCLK): Up to 50 MHz
Reset RES# pin reset, power-on reset, voltage-monitoring reset, independent watchdog timer
reset, watchdog timer reset, deep software standby reset, and software reset
Voltage detection circuit When the voltage on VCC passes the voltage detection level (Vdet), an internal reset or
internal interrupt is generated.
