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 (V25TM and V35TM)
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.
FEATURES
• Internal 16-bit architecture, selectable external data bus width (16/8 bits)
• Software compatible with V20TM and V30TM (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
16-Mbyte extended memory space
• Register file space (in on-chip RAM) : 512 bytes/16 register banks
• I/O space : 64K bytes
• Automatic wait control with memory space divided in variable sizes (max. 6
blocks)
• I/O line (input ports: 11 bits, input/output ports: 42 bits)
• 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
• Interrupt controller
• Programmable priority (4 levels)
• Three interrupt servicing methods
Vectored interrupt function, register bank switching function, macro service
function
• 16-bit timer: 4 channels
• Watchdog timer function
• Software interval timer (16 bits)
• Address field wait insertion function and RAS/CAS switchover timing
generation function
• DRAM and pseudo-SRAM refresh functions
• Standby functions (STOP mode, HALT mode)
• On-chip clock generator
APPLICATIONS
• Control of data processing systems using serial or parallel communication
(Data processing terminals, printer, G3 facsimile, etc.)
