MOS INTEGRATED CIRCUIT
µPD70433
V55PI^TM
16-BIT MICROPROCESSOR
DESCRIPTION
The µPD70433 (V55PI) is a microprocessor in which a 16-bit CPU, RAM, serial interface, parallel interface, A/D
converter, timers, DMA controller, interrupt controller, etc., are integrated in a single chip.
The V55PI is software-compatible with the µPD70320 and 70330 (V25^TM and V35^TM) single-chip microcontrollers. The
V55PI provides a migration path from the V25. It offers higher-level functions and higher performance, and is particularly
suitable for control of data processing systems associated with mechanical control, including printer and facsimile.
Detailed functions are described in the following user’s manuals, which should be read when carrying out
design work.
• V55PI User’s Manual Hardware
: U10514E
• V55PI User’s Manual Instruction
: U10231E
FEATURES
• Internal 16-bit architecture, selectable external data bus width (16/8 bits)
• Software compatible with V20^TM and V30^TM (native mode) and V25 and V35 (includes additional instructions)
• Minimum instruction cycle: 160 ns/12.5 MHz (external 25 MHz)
125 ns/16 MHz (external 32 MHz)
• Address space: 16M bytes:
1-Mbyte basic memory space

• DMA controller (DMAC): Max. 4-channel configuration possible
• Four DMA transfer modes (single transfer, demand release, single step, burst)
• Intelligent DMA modes 1 and 2
• Serial interface: 2 channels
• Asynchronous mode (UART) or clocked mode (CSI) selectable
• Parallel interface: 8 bits
• Centronics data input/output and general-purpose data input/output
• A/D converter (8 bits): 4 channels
• Real-time output port: 4 bits × 2 channels or 8 bits × 1 channel
• PMW (Pulse Width Modulation) output function : 8 bits
