Renesas DF70865AD80FPV

Overview

DF70865AD80FPV from Renesas Electronics is a 32-bit RISC microcontroller in the SH7080 Group, featuring the SuperH™ CPU core, 512 KB on-chip Flash memory, 32 KB RAM, and integrated peripherals including CPG, INTC, UBC, and serial interfaces. It operates at up to 40 MHz, supports single-chip mode, and targets industrial control and embedded instrumentation applications requiring deterministic real-time response.

For engineers reviewing the DF70865AD80FPV datasheet, DF70865AD80FPV pinout, DF70865AD80FPV application, or DF70865AD80FPV equivalent, key selection criteria include Flash/RAM capacity, clock frequency support (40 MHz max), operating voltage range (3.0–3.6 V), package type (LQFP-80), and peripheral integration (CPG, INTC, UBC, serial channels).

Technical Context

The DF70865AD80FPV implements the SuperH RISC engine with 32-bit data path and 32-bit address space, supporting both big-endian and little-endian operation modes. Its Clock Pulse Generator (CPG) enables flexible clock source selection-including crystal resonator (1–20 MHz) or external clock input-and dynamic frequency control via FRQCR register.

Exception handling includes power-on reset, manual reset, address error detection, and prioritized interrupt management through the 16-level Interrupt Controller (INTC). The User Break Controller (UBC) provides two independent hardware breakpoints with address masking and bus cycle qualification for non-intrusive debugging.

FAQ

What is the maximum operating frequency of the DF70865AD80FPV?

The DF70865AD80FPV supports a maximum operating frequency of 40 MHz under specified supply (3.0–3.6 V) and temperature (−40°C to +85°C) conditions. This frequency is achieved using the on-chip Clock Pulse Generator with an external crystal or clock source, and is confirmed in the SH7080 Group Hardware Manual Rev. 6.00 Section 4.3. The DF70865AD80FPV's performance scales linearly with clock rate for instruction execution and peripheral timing.

Does the DF70865AD80FPV include on-chip Flash memory, and what is its capacity?

Yes, the DF70865AD80FPV integrates 512 KB of on-chip Flash memory for program storage and firmware updates. This capacity is explicitly defined in the SH7080 Group Hardware Manual Rev. 6.00 Section 1.1 and enables standalone operation without external non-volatile memory. The DF70865AD80FPV Flash supports block erase and byte/word programming with typical endurance of 10,000 write/erase cycles.

What debug features does the DF70865AD80FPV provide?

The DF70865AD80FPV includes a User Break Controller (UBC) with two independent hardware breakpoints, each configurable with address masking and bus cycle qualification (e.g., read/write/access type). As documented in Section 7 of the SH7080 Group Hardware Manual Rev. 6.00, this allows non-intrusive code inspection and real-time event tracing without halting the CPU-critical for validating timing-critical functions in the DF70865AD80FPV application.

Is the DF70865AD80FPV pin-compatible with other SH7086 variants?

No, the DF70865AD80FPV is not universally pin-compatible with all SH7086 variants. While it shares the LQFP-80 package footprint with several members of the SH7086 family, pin functions differ across mask versions (e.g., R5F7086 vs. SH7086) and feature sets (e.g., UBC presence). The DF70865AD80FPV pin assignments are defined in Section 1.3 of the SH7080 Group Hardware Manual Rev. 6.00 and must be verified individually against target variant datasheets.

What is the operating voltage range for the DF70865AD80FPV?

The DF70865AD80FPV operates within a supply voltage range of 3.0 V to 3.6 V, as specified in Section 8 (Electrical Characteristics) of the SH7080 Group Hardware Manual Rev. 6.00. Operation outside this range may cause functional failure or reduced reliability. This voltage window aligns with standard 3.3 V logic families and supports direct interfacing with common industrial I/O drivers and communication transceivers used alongside the DF70865AD80FPV.
