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 |
|---|---|---|---|
| R5F71374AD80FPV | Same silicon die and pinout; differs only in marking and packaging - no functional difference | Identical use cases; same qualification and reliability data | Select when sourcing from legacy Renesas distribution channels or requiring original factory marking |
| SH7266R | SH-2A core, 100 MHz, 1 MB flash, no on-chip ROM; requires external boot loader | Better suited for field-upgradable systems but lacks mask-ROM security and boot integrity | Choose for designs requiring firmware updates; avoid if mask-ROM tamper resistance is required |
Compared with R5F71374AD80FPV and SH7266R, DF71374AD80FPV#ZB offers guaranteed boot integrity via mask ROM, deterministic real-time latency from fixed-frequency PLL, and industrial temperature qualification without derating - critical for safety-monitored control loops.

FAQ
What is the maximum operating frequency of the DF71374AD80FPV#ZB?
The DF71374AD80FPV#ZB operates at a maximum system clock frequency of 80 MHz, achieved via its integrated Clock Pulse Generator with PLL. This frequency is fully supported across the specified industrial temperature range (–40°C to +85°C) and 3.3 V supply, enabling deterministic real-time execution for time-critical control tasks in the DF71374AD80FPV#ZB-based design.
Does the DF71374AD80FPV#ZB include on-chip flash or ROM memory?
The DF71374AD80FPV#ZB integrates 4 MB of on-chip mask ROM, not flash memory. This ROM is programmed during wafer fabrication and provides immutable, tamper-resistant storage for boot code and fixed application firmware. Unlike flash, it cannot be reprogrammed in-system, ensuring boot integrity and eliminating risk of accidental corruption in harsh industrial environments where the DF71374AD80FPV#ZB is deployed.
Is the DF71374AD80FPV#ZB pin-compatible with other SH7137 Group variants?
Yes, the DF71374AD80FPV#ZB shares identical pin assignment and electrical characteristics with other SH7137 Group members in the 144-pin LQFP package, including R5F71374AD80FPV and SH7137 derivatives. All share the same mechanical footprint, power pin layout, and peripheral pin mapping per the SH7137 Group Hardware Manual Rev. 3.00, allowing direct substitution within the same PCB design for the DF71374AD80FPV#ZB and its siblings.
What communication interfaces does the DF71374AD80FPV#ZB support?
The DF71374AD80FPV#ZB supports dual CAN 2.0B controllers, four asynchronous serial interfaces (SCI), and an I²C-compatible serial interface. These are implemented in hardware with dedicated registers and interrupt vectors. No USB, Ethernet, or SPI peripherals are integrated - external PHY or bridge ICs are required for those protocols in a DF71374AD80FPV#ZB-based system.
What debug capabilities are available on the DF71374AD80FPV#ZB?
The DF71374AD80FPV#ZB provides full on-chip debug support via IEEE 1149.1 (JTAG) interface, enabling real-time instruction trace, hardware breakpoints, register read/write, and memory inspection without halting system operation. This capability is built into the SuperH™ core and requires no additional debug firmware - all debug functions operate directly through the DF71374AD80FPV#ZB's dedicated TDI/TDO/TCK/TMS pins.
