For engineers reviewing the DF71324AD80FPV#GZ datasheet, DF71324AD80FPV#GZ pinout, DF71324AD80FPV#GZ application, or DF71324AD80FPV#GZ equivalent, key selection criteria include clock frequency (40 MHz), memory configuration (128 KB ROM / 8 KB RAM), operating voltage (3.0–3.6 V), package type (100-pin LQFP), and peripheral integration (3-channel UART, 1-channel I²C, 8-channel 16-bit timers).

Technical Context

The DF71324AD80FPV#GZ implements the SuperH RISC engine SH-2 architecture with 32-bit data bus and 32-bit address space. It integrates a Clock Pulse Generator (CPG) supporting crystal/resonator input (4–20 MHz) and internal PLL for 40 MHz operation, alongside power-on reset, manual reset, and oscillation stop detection circuits.

Peripheral subsystems include three asynchronous serial interfaces (SCI), one I²C-compatible serial interface (IIC), eight 16-bit general-purpose timers (TPU), and a 10-bit ADC with 8 channels. All modules are memory-mapped and controlled via dedicated registers accessible in user or privileged mode.

FAQ

What is the maximum operating frequency of the DF71324AD80FPV#GZ?

The DF71324AD80FPV#GZ operates at a maximum system clock frequency of 40 MHz, achieved via its on-chip PLL that multiplies an external 8 MHz crystal input. This frequency is fully supported across all operating voltage ranges (3.0–3.6 V) and ambient temperatures (–40°C to +85°C), enabling tight timing control in motor drive and industrial communication applications. The DF71324AD80FPV#GZ maintains instruction throughput consistency without derating under specified conditions.

Does the DF71324AD80FPV#GZ include on-chip flash or ROM memory?

The DF71324AD80FPV#GZ integrates 128 KB of mask-programmed ROM for program storage and 8 KB of SRAM for runtime data - no flash memory is present. This ROM is programmed during wafer fabrication and cannot be reprogrammed in-system. The DF71324AD80FPV#GZ relies on this fixed-code execution model for deterministic boot and safety-critical applications where runtime code modification is prohibited.

What peripheral interfaces are available on the DF71324AD80FPV#GZ?

The DF71324AD80FPV#GZ provides three asynchronous serial communication interfaces (SCI), one I²C-compatible serial interface (IIC), eight 16-bit general-purpose timers (TPU), a 10-bit 8-channel ADC, and a watchdog timer. All peripherals are memory-mapped and accessible via dedicated control registers. No CAN, USB, or Ethernet interfaces are integrated - those require external companion ICs when needed in the DF71324AD80FPV#GZ-based system.

Is the DF71324AD80FPV#GZ pin-compatible with other SH7132 Group members?

Yes, the DF71324AD80FPV#GZ shares identical pin assignment and electrical characteristics with other 100-pin LQFP variants in the SH7132 Group, including SH7132R and SH7132S. Pin-to-pin compatibility extends to power, clock, reset, and all peripheral I/O signals - allowing board-level reuse across different memory configurations within the same package footprint. The DF71324AD80FPV#GZ maintains full mechanical and electrical interoperability in this family context.

What is the recommended power supply configuration for the DF71324AD80FPV#GZ?

The DF71324AD80FPV#GZ requires separate 3.3 V supplies for VCC (core/I/O), AVCC (analog), and VPLL (PLL circuit), each decoupled with ≥1 µF ceramic capacitors near respective pins. A clean 3.0–3.6 V rail must be maintained under all operating conditions; voltage drop below 2.7 V triggers power-on reset. The DF71324AD80FPV#GZ specifies strict sequencing: AVCC must be stable before VCC, and both must be present before applying clock or releasing reset - ensuring reliable ADC and PLL initialization.
