MOS INTEGRATED CIRCUIT
µPD70325
V25+TM
16/8-BIT SINGLE-CHIP MICROCONTROLLER
The µPD70325 (V25+) is a single-chip microcontroller on which 16-bit CPU, RAM, serial interface, timer, DMA
controller, interrupt controller, etc. are all integrated. The µPD70325 is software compatible with the 16/8-bit single-
chip microcontroller µPD70320 (V25TM). The V25+ greatly improves the DMA responsivity and transfer rate compared

to the V25.
FEATURES
• Software compatible with V25
• Software compatible with µPD70108/70116 (in native mode) (some instructions added)
• Internal 16-bit architecture and external 8-bit data bus
• 3-stage pipeline method
• Minimum instruction cycle : 250 ns/8 MHz (external 16 MHz)
: 200 ns/10 MHz (external 20 MHz)
• Memory space 1 Mbyte
• On-chip RAM : 256 words × 8 bits
• Register bank (memory mapped method) : 8 banks
• Input port (port T) with comparator : 8 bits
• I/O lines (input port : 4 bits, input/output ports : 20 bits)
• Serial interface : 2 channels
• Internal dedicated baud rate generator
• Asynchronous mode and I/O interface mode
• Interrupt controller
• Programmable priority (8 levels)
• 3 types of interrupt response method
Vectored interrupt function, register bank switching function, macro service function
• DRAM and pseudo SRAM refreshing function
• DMA controller : 2 channels
• 4 types of DMA transfer mode
• Transfer rate Maximum 4 Mbytes/second (when stop control is not executed by DMARQ pin in demand release
mode)
Maximum 2 Mbytes/second (when stop control is executed by DMARQ pin in demand release
mode, or burst mode)
• Address pointer (linear) : 20 bits
• Terminal counter : 16 bits
• 16-bit timer : 2 channels
• Time base counter (20 bits) : 1 channel
• On-chip clock generator
• Programmable wait function
• Standby function (STOP, HALT)
