Interrupt controller:
General-purpose input
and output ports:
External bus interface
BCU (bus control unit) built-in
• 24-bit address bus (internal 28-bit processing)
• 16-bit data bus
Data size is selectable from 8 bits and 16 bits in each area.
• Little-endian memory access; big-endian may be set in each area.
• Memory mapped I/O
• Chip enable and wait control circuits built-in
• DRAM direct interface function built-in
Supports fast page mode and EDO page mode.
Supports self-refresh and CAS-before RAS refresh.
• Supports SDRAM.
Supports SDRAM self-refresh.
• Supports burst ROM.

50 MHz max. (core voltage = 3.3 V ±0.3 V)
LCD controller operating clock frequency
25 MHz max. (core voltage = 3.3 V ±0.3 V)
* When the SDRAM controller is used
(core voltage = 3.3 V ±0.3 V and PLL is used),
In x1 speed mode: CPU = Bus = 25 MHz max.
In x2 speed mode: CPU = 35 MHz max., Bus = 17.5 MHz max.
-40 to 85°C
During SLEEP
During HALT
During execution
Note: The values of power consumption during execution were measured when a test
program that consisted of 55% load instructions, 23% arithmetic operation
instructions, 1% mac instruction, 12% branch instructions and 9% ext
instruction was being continuously executed.
