Product details
Overview
DF70845AD80FPV from Renesas Electronics is a 32-bit RISC microcontroller in the SH7084 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 33 MHz and targets industrial control and embedded instrumentation applications requiring deterministic real-time response.
For engineers reviewing the DF70845AD80FPV datasheet, DF70845AD80FPV pinout, DF70845AD80FPV application, or DF70845AD80FPV equivalent, key selection criteria include Flash/RAM capacity, clock frequency support (up to 33 MHz), operating voltage range (3.0–3.6 V), package type (LQFP-144), and peripheral integration (CPG, INTC, UBC, serial I/O).
Technical Context
The DF70845AD80FPV 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 CPU includes 16 general-purpose registers, system control registers, and hardware exception handling with vector-based interrupt management.
On-chip clock generation uses the Clock Pulse Generator (CPG) with crystal resonator or external clock input support, enabling programmable frequency division and oscillator stop detection. The Interrupt Controller (INTC) supports 64 interrupt sources with priority encoding and nested interrupt handling.
Key Specifications

Pinout & Package
LQFP-144 package with 0.5 mm lead pitch, 20 mm × 20 mm body, and exposed thermal pad (EP). Pin 1 marked by dot; pins numbered counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Core & I/O Power Supply | 3.0–3.6 V supply for internal logic and GPIO; requires local decoupling per Renesas layout guidelines. |
| VSS | Digital Ground | Reference return path for digital circuits; must be connected to low-impedance ground plane. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit RISC microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F70845ADFPV | Same SH7084 core, identical Flash/RAM, but rated for Standard quality grade only (not High Quality); lacks extended temperature validation. | Suitable for office equipment or consumer-grade instrumentation where automotive/industrial temp range not required. | Select R5F70845ADFPV only if full −40 °C to +85 °C operation and High Quality grade certification are unnecessary. |
| SH7084D50FPV | Same package and pinout, but lower max frequency (25 MHz) and reduced Flash (256 KB); shares identical peripheral set and register map. | Applicable where cost sensitivity outweighs performance needs, e.g., simple sensor nodes or basic control functions. | Choose SH7084D50FPV when 33 MHz operation and 512 KB Flash are not required - reduces BOM cost without redesign. |
Compared with DF70845AD80FPV, R5F70845ADFPV omits High Quality grade validation and extended temperature compliance, while SH7084D50FPV trades clock speed and memory capacity for lower cost - both retain pin compatibility and software portability within the SH7084 family.
