•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.
Operating conditions and power consumption
Operating voltage: Core (VDD)1.8 V to 3.6 V
I/O (V
DDE)1.8 V to 5.5 V
Operating clock frequency: CPU operating clock frequency
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.
Operating temperature: -40 to 85°C
Power consumption: During SLEEP 3.5 µW typ. (3.3 V)
During HALT 100 mW typ. (3.3 V, 50 MHz)
During execution 200 mW typ. (3.3 V, 50 MHz)
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.
Supply form
