S1C33210 PRODUCT PART
General-purpose input
Shared with the I/O pins for internal peripheral circuits
and output ports:
Input port
7 bits
I/O port
27 bits
Mobile access interfaces
One PHS, PDC, and HDLC channel each
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 burst ROM.
Operating conditions and power consumption
Operating voltage:
V
DD
2.7 V to 3.6 V
Operating clock frequency: CPU
50 MHz max.
25 MHz max. (Mobile access interfaces)
Operating temperature:
-40 to 85
°
C
Power consumption:
During SLEEP
4
µ
W typ.
During HALT
122 mW typ.
(3.3 V, 50 MHz)
During execution
238 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
QFP15-128 pin plastic package.
