Renesas DF71464AD80FPV#GZ

Overview

DF71464AD80FPV#GZ from Renesas Electronics is a 32-bit SuperH™ RISC microcontroller in the SH7146 Group, featuring a 32-bit CPU core, on-chip RAM and ROM, integrated CPG for clock generation, INTC for interrupt management, and UBC for real-time debugging. It operates at up to 80 MHz and targets embedded control applications requiring deterministic timing and peripheral integration.

For engineers reviewing the DF71464AD80FPV#GZ datasheet, DF71464AD80FPV#GZ pinout, DF71464AD80FPV#GZ application, or DF71464AD80FPV#GZ equivalent, key selection criteria include its 80 MHz max operating frequency, 32-bit SuperH RISC architecture, integrated clock pulse generator (CPG), interrupt controller (INTC), and user break controller (UBC) support - all confirmed in the SH7146 Group Hardware Manual Rev. 4.00.

Technical Context

The DF71464AD80FPV#GZ implements the SuperH RISC engine with 32-bit data and address buses, supporting MCU Extension Modes 0–3 and Single Chip Mode. Its Clock Pulse Generator (CPG) enables dynamic frequency control via FRQCR register and supports crystal resonator or external clock input with oscillator stop detection.

Interrupt handling uses a dedicated Interrupt Controller (INTC) with priority registers (IPRA, IPRD–IPRF, IPRH–IPRL) and vector-based dispatch. The User Break Controller (UBC) provides hardware breakpoints via BARA/BARB and BAMRA/BAMRB registers, enabling non-intrusive code execution monitoring without software instrumentation.

FAQ

What is the maximum operating frequency of the DF71464AD80FPV#GZ?

The DF71464AD80FPV#GZ operates at a maximum frequency of 80 MHz, as specified in the SH7146 Group Hardware Manual Rev. 4.00. This frequency is achieved using the on-chip Clock Pulse Generator (CPG) with an external crystal or clock source. System timing, peripheral operation, and interrupt latency are all rated under this condition, and exceeding it may result in undefined behavior or reduced reliability.

Does the DF71464AD80FPV#GZ include on-chip debug support?

Yes, the DF71464AD80FPV#GZ integrates a User Break Controller (UBC) with dual hardware breakpoint channels (BARA/BARB and associated mask registers). This enables non-intrusive code execution monitoring, conditional breakpoint triggering, and real-time trace without modifying firmware - a capability confirmed in Sections 7.1–7.3 of the SH7146 Group Hardware Manual Rev. 4.00.

What package type and pin count does the DF71464AD80FPV#GZ use?

The DF71464AD80FPV#GZ is packaged in a 144-pin LQFP (Low-Profile Quad Flat Package) with 0.5 mm pitch, as documented in Section 9 ("Product Type, Package Dimensions, etc.") of the SH7146 Group Hardware Manual Rev. 4.00. Pin assignments and functions are detailed in Sections 1.3 and 1.4 of the same manual.

Is the DF71464AD80FPV#GZ pin-compatible with other SH7146 Group members?

DF71464AD80FPV#GZ shares the same 144-pin LQFP package and pinout with other SH7146 Group variants such as R5F71464AD80FPV#GZ and SH7146R5F71464AD80FPV, as verified in the "Pin Assignments" section (1.3) of the SH7146 Group Hardware Manual Rev. 4.00. Functional differences between variants relate to memory size or feature enablement, not physical interface.

What development tools are supported for the DF71464AD80FPV#GZ?

The DF71464AD80FPV#GZ is supported by Renesas' High-Performance Embedded Workshop 3 IDE (REJ10B0025), SH-1/SH-2/SH-DSP Software Manual (REJ09B0171), and C/C++ Compiler Package V.9.00 (REJ10B0152). These tools provide full debug visibility via the UBC, register-level simulation, and optimized code generation aligned with the SuperH RISC architecture of the DF71464AD80FPV#GZ.
