Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F72011W100FPV | Same SH-7201 group, identical pinout and peripheral set, but with 1 MB Flash and 128 KB SRAM | Required when application firmware exceeds 512 KB or requires larger runtime data buffers | Select R5F72011W100FPV only if additional Flash/SRAM capacity is needed; otherwise DS72011RW100FPV offers optimal cost/performance balance |
| RA6M4GFP100A | Arm® Cortex®-M4F core, 200 MHz, 1 MB Flash, 384 KB SRAM, no native CAN FD support | Preferred for new designs requiring Arm ecosystem tooling, USB HS, or TrustZone security features | RA6M4GFP100A is not pin-compatible; requires PCB redesign but provides higher clock speed and modern peripheral set |
Compared with R5F72011W100FPV, DS72011RW100FPV reduces Flash overhead for legacy industrial firmware while maintaining full peripheral compatibility; versus RA6M4GFP100A, it offers drop-in replacement capability for existing SH-2A-based designs but lacks Arm-specific IP blocks and USB connectivity.

FAQ
What is the maximum operating frequency of the DS72011RW100FPV?
The DS72011RW100FPV operates at a maximum CPU frequency of 100 MHz, achieved using its on-chip PLL with programmable multiplication ratio. This frequency is fully supported across the full industrial temperature range (–40°C to +85°C) and requires a stable 4–20 MHz external clock source applied to the CLKIN pin. The DS72011RW100FPV maintains timing compliance under worst-case voltage and temperature conditions as specified in Renesas' Electrical Characteristics table (Section 8 of R01UH0026EJ0300).
Does the DS72011RW100FPV include a hardware floating-point unit?
Yes, the DS72011RW100FPV integrates a full IEEE 754-compliant single-precision floating-point unit (FPU) as part of its SH-2A CPU core. This FPU executes addition, multiplication, division, square root, and transcendental instructions in hardware, delivering up to 8× faster computation than software-emulated alternatives. The DS72011RW100FPV FPU is directly accessible via standard SH-2A instruction mnemonics and supports denormalized numbers and NaN handling per the manual's Section 3.
What package type and pin count does the DS72011RW100FPV use?
The DS72011RW100FPV uses a 100-pin LQFP package measuring 14 mm × 14 mm with 0.5 mm pin pitch and an exposed thermal pad. This package is explicitly documented in Renesas' Hardware User's Manual R01UH0026EJ0300 (Appendix: Product Type, Package Dimensions). The DS72011RW100FPV pinout includes dedicated power/ground distribution, dual CAN transceiver interfaces, and multiplexed I/O supporting UART, ADC, and PWM functions as defined in Section 1.4 of the manual.
Is the DS72011RW100FPV qualified for industrial temperature operation?
Yes, the DS72011RW100FPV is rated for industrial temperature operation from –40°C to +85°C, as confirmed in Renesas' official documentation and electrical characteristics tables. This qualification aligns with Renesas' "Standard" quality grade, making the DS72011RW100FPV suitable for factory automation, motor drives, and building control systems deployed in uncontrolled ambient environments. The DS72011RW100FPV undergoes screening and characterization across this full range for parameters including clock stability, ADC accuracy, and I/O drive strength.
How many CAN interfaces does the DS72011RW100FPV support?
The DS72011RW100FPV supports two independent CAN 2.0B controllers (CAN0 and CAN1), each with dedicated TX/RX pins, message buffers, and acceptance filtering logic. Both controllers comply with ISO 11898-1:2003 and support bit rates up to 1 Mbps. These interfaces are electrically isolated from each other and can operate simultaneously on separate networks - a capability confirmed in the DS72011RW100FPV's peripheral description (Section 6.2.11 of R01UH0026EJ0300) and used in applications like redundant fieldbus communication.
