General-purpose input

Shared with the I/O pins for internal peripheral circuits

and output ports:

Input port

13 bits

 

 

I/O port

29 bits

 

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.

Operating conditions and power consumption

Operating voltage:

Core (VDD)

1.8 V to 3.6 V

 

I/O (VDDE)

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.
