Product details
Overview
DF70854AN80FPV from Renesas Electronics is a 32-bit RISC microcontroller in the SH7085 subgroup of the SH7080 family, featuring the SuperH™ CPU core, 512 KB on-chip Flash memory, 32 KB RAM, and integrated peripherals including CPG, INTC, UBC, and multiple serial interfaces. It operates at up to 40 MHz and targets industrial control and embedded instrumentation applications requiring deterministic real-time response.
For engineers reviewing the DF70854AN80FPV datasheet, DF70854AN80FPV pinout, DF70854AN80FPV application, or DF70854AN80FPV equivalent, key selection criteria include its 80-pin LQFP package, 3.3 V single-supply operation, Flash memory endurance (10,000 write/erase cycles), on-chip debug support via JTAG, and compliance with industrial temperature range (−40°C to +85°C).
Technical Context
The DF70854AN80FPV implements the SH-2 CPU architecture with 32-bit data path, 32 general-purpose registers, and a 16-bit instruction set for high code density. Its Clock Pulse Generator supports multiple clock sources - crystal resonator (1–20 MHz), external clock input, or internal oscillator - with programmable frequency division and oscillation stop detection.
The interrupt controller provides 128 vectorized interrupt sources with priority levels configurable per source, while the User Break Controller enables hardware breakpoints on address, data, and bus cycle conditions - critical for real-time debugging in safety-critical firmware development.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F70854MNEFP | Same SH-2 core and peripheral set, but in 100-pin PQFP package with additional I/O (76 pins) and extra timers | Suitable for designs requiring more GPIO or advanced timer functions (e.g., three-phase motor commutation) | Select when board layout allows larger footprint and higher I/O count is needed; not pin-compatible with DF70854AN80FPV |
| SH7085F20A | Legacy SH7085 variant with 20 MHz max frequency, 256 KB Flash, and no UBC hardware breakpoint support | Applicable only in cost-sensitive, lower-performance legacy upgrades where debug depth is secondary | Choose only for backward compatibility in maintenance-only projects; lacks modern debug and memory capacity |

FAQ
What is the maximum operating frequency of the DF70854AN80FPV?
The DF70854AN80FPV operates at a maximum frequency of 40 MHz under specified conditions (VCC = 3.3 V ±0.3 V, TA = −40°C to +85°C). This frequency is achieved using the on-chip Clock Pulse Generator with external crystal (up to 20 MHz) and internal PLL multiplication. Exceeding this limit may cause timing violations in peripheral modules or CPU instruction fetch stalls.
Does the DF70854AN80FPV support in-system programming (ISP) of its on-chip Flash memory?
Yes, the DF70854AN80FPV supports in-system programming via its on-chip Flash memory controller and JTAG interface. Firmware updates can be performed without removing the DF70854AN80FPV from the target board, using standard Renesas flash programming tools such as Flash Development Toolkit (FDT) and compatible debug probes.
What debug capabilities does the DF70854AN80FPV provide?
The DF70854AN80FPV integrates a full-featured User Break Controller (UBC) supporting hardware address and data breakpoints, plus IEEE 1149.1 JTAG boundary-scan. These features enable non-intrusive real-time debugging, memory access tracing, and structural testing - all without modifying application code or consuming CPU cycles.
Is the DF70854AN80FPV qualified for automotive applications?
No, the DF70854AN80FPV is classified by Renesas as a "Standard" quality grade product intended for industrial, office, and consumer equipment. It is not AEC-Q100 qualified and lacks the extended temperature range (−40°C to +125°C), enhanced ESD immunity, or failure-in-time (FIT) reporting required for automotive use.
What package type and pin count does the DF70854AN80FPV use?
The DF70854AN80FPV uses an 80-pin LQFP package (12 mm × 12 mm, 0.5 mm pitch) with exposed thermal pad. This package provides 64 user I/O pins, 8 power/ground pins, and dedicated JTAG/debug signals - optimized for compact industrial PCB layouts requiring thermal efficiency and manufacturability.
