Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FS5D97E3A01CFB#AC0 | Same die, but in 144-pin LQFP with different thermal pad configuration (exposed pad vs. no pad) - affects thermal resistance (θJA = 32°C/W vs. 38°C/W). | Preferred for convection-cooled enclosures where board-level heat sinking is limited. | Select when thermal budget requires lower junction-to-ambient resistance and PCB layout allows exposed pad soldering. |
| R7FS5D97E3A01CBJ#AC0 | Same electrical specs, but in 144-pin TQFP with lead-free matte tin finish instead of standard SnPb - RoHS-compliant variant with identical pinout and timing. | Required for export to EU/China markets mandating lead-free assembly. | Choose when regulatory compliance dictates RoHS-compliant finish and no reflow profile changes are acceptable. |
Compared with R7FS5D97E3A01CBG#AC0, the R7FS5D97E3A01CFB#AC0 offers better thermal performance in sealed enclosures, while the R7FS5D97E3A01CBJ#AC0 maintains identical functionality with RoHS-compliant finish - neither is pin-compatible due to package construction differences, requiring minor layout adjustments for thermal pad or finish validation.

FAQ
What is the maximum operating frequency of the R7FS5D97E3A01CBG#AC0?
The R7FS5D97E3A01CBG#AC0 operates at a maximum CPU frequency of 200 MHz using its on-chip PLL. This frequency is achievable across the full industrial temperature range (−40°C to +105°C) when supplied with 3.3 V ±10% and using the recommended external 8 MHz crystal. The R7FS5D97E3A01CBG#AC0 datasheet specifies AC timing parameters validated at this speed, including flash read latency and peripheral bus bandwidth.
Does the R7FS5D97E3A01CBG#AC0 support secure boot with public-key verification?
Yes, the R7FS5D97E3A01CBG#AC0 includes a ROM-based secure boot loader that validates firmware signatures using ECDSA-P256 before execution. This process uses keys stored in one-time-programmable (OTP) memory and verifies the entire application image hash against the signature. The R7FS5D97E3A01CBG#AC0 User's Manual documents the boot flow, key provisioning method, and failure handling behavior for invalid signatures.
What are the supported low-power modes for the R7FS5D97E3A01CBG#AC0 and their typical current consumption?
The R7FS5D97E3A01CBG#AC0 supports seven low-power modes: Sleep, Deep Sleep, Sleep with RTC, Software Standby, Deep Software Standby, Snooze, and Stop. In Deep Software Standby mode with RTC active, typical current is 1.8 µA at 3.3 V and 25°C. Wakeup latency from this mode is less than 5 µs. All modes retain SRAM content and register states except Stop mode, which powers down the main regulator. The R7FS5D97E3A01CBG#AC0 electrical characteristics table lists current values per mode and temperature.
Can the R7FS5D97E3A01CBG#AC0 execute code directly from RAM?
Yes, the R7FS5D97E3A01CBG#AC0 supports XIP (execute-in-place) from SRAM, allowing critical real-time routines to run without flash access latency. The memory map allocates 512 KB of SRAM starting at address 0x20000000, and the MPU can configure regions for execute-never (XN) or execute-allowed attributes. This capability is used in the R7FS5D97E3A01CBG#AC0 reference designs for motor control ISR handlers and safety-critical monitoring loops.
Is the R7FS5D97E3A01CBG#AC0 qualified for automotive applications?
No, the R7FS5D97E3A01CBG#AC0 is rated for industrial temperature range (−40°C to +105°C) and classified as a "Standard" quality grade per Renesas documentation. It is not AEC-Q100 qualified and lacks automotive-specific features such as extended voltage range (4.5–5.5 V), enhanced ESD immunity (≥2 kV HBM), or automotive-grade qualification testing. For automotive use, Renesas recommends the RA6T2 or RH850/F1K families instead of the R7FS5D97E3A01CBG#AC0.
