Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA6T2AB3CFL#BA0 | Same RA2A2 family, identical package and pinout, but SDADC24 limited to 4 channels (vs. 7) | Suitable for cost-sensitive metering where fewer analog inputs are required | Select when 4-channel SDADC24 suffices and BOM cost optimization is prioritized |
| R7FA4M2AD3CFP#AA0 | RA4M2 series, 48 MHz Cortex-M33, 512-KB flash, 128-KB SRAM, no SDADC24, adds USB FS and CAN FD | Better suited for connectivity-heavy applications requiring USB/CAN rather than ultra-high-resolution analog | Choose when system-level communication bandwidth outweighs metrology precision requirements |
Compared with R7FA6T2BB3CFL#BA0, the R7FA6T2AB3CFL#BA0 reduces SDADC24 channel count while maintaining identical security and timing features, whereas the R7FA4M2AD3CFP#AA0 trades metrology capability for enhanced connectivity-making the R7FA6T2BB3CFL#BA0 optimal for analog-intensive, security-critical edge nodes.

FAQ
What is the maximum sampling rate of the 24-bit Sigma-Delta ADC in R7FA6T2BB3CFL#BA0?
The R7FA6T2BB3CFL#BA0's SDADC24 supports a maximum sampling rate of 7.813 kHz in differential mode with 12 MHz main oscillator clock and PLL multiplication. This rate is fixed per configuration and applies to all 7 input channels. The R7FA6T2BB3CFL#BA0 datasheet specifies this value under "Sampling Rate" in Section 1.8 (Analog). No software scaling or oversampling increases this base rate.
Does R7FA6T2BB3CFL#BA0 support hardware-accelerated AES encryption with Galois/Counter Mode (GCM)?
Yes, the R7FA6T2BB3CFL#BA0 includes a dedicated hardware AES engine supporting GCM mode with 128- and 256-bit keys, as confirmed in Section 1.11 (Security) of the R01DS0418EJ0130 datasheet. The R7FA6T2BB3CFL#BA0 implements full authenticated encryption with associated data (AEAD), enabling secure firmware updates and encrypted sensor telemetry without CPU overhead.
What is the RTC backup supply configuration for R7FA6T2BB3CFL#BA0?
The R7FA6T2BB3CFL#BA0 features an independent power supply RTC powered via the VRTC pin, supporting calendar mode (2000–2099), alarm, and clock correction functions. When main VCC drops, the RTC continues operating from a coin-cell or supercapacitor connected to VRTC, with low-voltage detection (4 interrupt levels) ensuring reliable timekeeping during brownout conditions.
How many general-purpose I/O pins does R7FA6T2BB3CFL#BA0 provide in its 100-pin LQFP package?
The R7FA6T2BB3CFL#BA0 provides 77 total I/O terminals in its 100-pin LQFP package: 67 bidirectional I/O pins, 3 input-only pins (P214, P215, P200), and 1 output-only pin (P600). This count excludes dedicated power, analog, clock, and debug pins, and is explicitly documented in Table 1.11 (I/O ports) of the R01DS0418EJ0130 datasheet.
Is R7FA6T2BB3CFL#BA0 pin-compatible with other RA2A2 group members like R7FA2A2AD3CFP?
Yes, R7FA6T2BB3CFL#BA0 is fully pin-compatible with R7FA2A2AD3CFP and other 100-pin LQFP variants in the RA2A2 group, sharing identical pin assignments, electrical characteristics, and mechanical footprint. This compatibility enables scalable design reuse across performance tiers while preserving PCB layout integrity-confirmed in Figure 1.3 (Pin assignment) and Section 1.3 (Part Numbering) of the datasheet.
