Features
CMOS process
High speed, low power consumption
Upward software and pin compatible,
including interfacing with peripheral
controller
Measures taken to increase speed
• Dual data bus system
• Effective address generation circuit
• Multiplication/division by program-
mable shifter
• High speed processing by
dedicated register
Two operating modes
• 8080 emulation mode added
Standby function
V20/V30 compatible, high speed low
voltage operation
• Capable of operating at 16 MHz
(at 5 V)
• Capable of operating at 3 V
(at 8 MHz)
• Clock can be stopped
Performance is approximately 4 times
higher than V30
16M-byte address extension mode
Internal bus sizing function
1 bus cycle = 2 clocks
Internal floating point processor
(
µ
PD72291) interface function
V20/V30 + peripheral controllers
V20/V30 CPU plus the following
peripheral functions:
• 4-ch DMA controller
• 3-ch 16-bit timer/counter
• Interrupt controller
• Clock generator
• DRAM refresh controller
• Programmable wait generator
(Internal peripheral controllers are
subset functions of
µ
PD7105X series)
V40/V50 upper compatible, high
speed low voltage operation
• Capable of operating at 20 MHz
(at 5 V)
• Capable of operating at 3 V
(at 10 MHz)
• Selectable clock frequency
• Enhanced peripheral functions
V33A + enhanced peripheral
functions of V40/V50
• DMA capable of supporting 16MB
space
• Dedicated BRG for timer/counter
• Low power control
· Stop mode
· Halt mode
· Variable clock mode
• Capable of operating at 3 V and
10 MHz (only for V53A)
• Capable of operating at 4 V and 16
MHz (only for V53A)
