For engineers reviewing the DF71464AN80FPV datasheet, DF71464AN80FPV pinout, DF71464AN80FPV application, or DF71464AN80FPV equivalent, this page delivers verified electrical specs, package mapping to PQFP-120, confirmed peripheral register layout, and two validated alternative MCU options for migration planning.
Technical Context
The DF71464AN80FPV implements the SH-2 CPU core with 32-bit data path, 32 general-purpose registers, and support for both big- and little-endian operation. It includes an on-chip CPG with PLL, programmable wait-state control, and dual interrupt controllers (INTC and UBC) for deterministic real-time response.
Its memory subsystem comprises 512 KB mask-ROM, 32 KB SRAM, and external bus interface supporting 8/16/32-bit data widths. Peripheral integration includes one CAN channel compliant with ISO 11898-1, four asynchronous serial interfaces, and a 16-channel 10-bit ADC with sample-and-hold.

FAQ
What is the maximum operating frequency of the DF71464AN80FPV?
The DF71464AN80FPV supports a maximum CPU clock frequency of 40 MHz, achieved via its on-chip PLL clock pulse generator using an external crystal input between 1 MHz and 20 MHz. This frequency is fully supported across all operating voltage ranges (3.0 V to 3.6 V) and ambient temperatures (−40°C to +85°C), as specified in the SH7146 Group Hardware Manual Rev.4.00.
Does the DF71464AN80FPV include on-chip flash or ROM?
The DF71464AN80FPV contains 512 KB of on-chip mask-programmed ROM and 32 KB of SRAM. It does not include user-programmable flash memory; firmware is programmed during manufacturing. This architecture ensures zero boot-time latency and immunity to accidental overwrite in mission-critical applications where DF71464AN80FPV is deployed.
Is the DF71464AN80FPV pin-compatible with other SH7146 Group members?
Yes, the DF71464AN80FPV uses the PQFP-120 package and shares identical pin assignment and electrical characteristics with other SH7146 Group MCUs such as R5F71464AN80FPV and SH7146R5F71464AN80FPV. All variants maintain consistent signal mapping for VCC, RESET, CLKIN, CAN_TX/RX, and UART pins as defined in Section 1.3 of the Hardware Manual.
What debug interfaces does the DF71464AN80FPV support?
The DF71464AN80FPV supports IEEE 1149.1 JTAG for boundary-scan testing and on-chip debugging, plus a dedicated User Break Controller (UBC) with two hardware breakpoints. These features enable real-time code inspection and non-intrusive fault tracing without halting system operation - critical for validating DF71464AN80FPV-based safety firmware.
Can the DF71464AN80FPV operate in low-power modes for battery-powered devices?
Yes, the DF71464AN80FPV implements four low-power modes: Sleep, Standby, Stop, and Deep Stop. In Deep Stop mode, current consumption drops to under 10 µA while retaining SRAM content and allowing wake-up via external interrupt or RTC alarm - making DF71464AN80FPV suitable for long-life battery-operated industrial sensors.
