GENERAL
The µPD784938 Subseries consists of 78K/IV Series products that combine a 78K/IV Series CPU core enabling mounting large-capacity memory and a IEBusTM (Inter Equipment BusTM) controller. The 78K/IV Series consists of 16-bit single-chip microcontrollers, and comes with a high-performance CPU that has various functions including a function to access 1-Mbyte memory spaces.
Features
• 78K/IV Series
• High-speed instruction execution
• Minimum instruction execution time: 320 ns (@ 6.29-MHz operation)
160 ns (@ 12.58-MHz operation)
• Instruction set suitable for control applications
• Data memory expansion function (1-Mbyte memory space: 2 bank specification pointers)
• Interrupt controller (4-level priority system)
• Vectored interrupt service/macro service/context switching
• Standby functions: HALT/STOP/IDLE modes
• Internal memory: • ROM
Mask ROM: 256 Kbytes (µPD784938)
192 Kbytes (µPD784937)
128 Kbytes (µPD784936)
96 Kbytes (µPD784935)
Flash memory: 256 Kbytes (µPD78F4938)
• RAM: 10,240 bytes (µPD784938, 78F4938)
8,192 bytes (µPD784937)
6,656 bytes (µPD784936)

• CSI (3-wire serial I/O): 2 channels
• Real-time output ports (combination with timer/counter allows independent control of 2-system stepping motors)
• A/D converter (8-bit resolution × 8 channels)
• PWM outputs (12-bit resolution × 2 channels)
• On-chip simple model with IEBus controller
• Watch timer (operation with main clock possible in the IDLE mode)
• Power-saving regulator
• High-performance timer/counter
• Timer/event counter (16 bits) × 3 units
• Timer (16 bits) × 1 unit
• Watchdog timer: 1 channel
• Clock output function: fCLK, fCLK/2, fCLK/4, fCLK/8, fCLK/16 can be selected
• On-chip ROM correction function
