Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power secure MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA2A2AD3CFP | Same RA2A2 family, identical 100-pin LQFP package, 7-channel SDADC24, but lacks integrated LCD controller | Preferred where LCD is driven externally or not required; higher I/O count (73 vs 67) and larger SLCDC segment support (45×4) | Select when LCD functionality is unnecessary and maximum GPIO flexibility is prioritized over display integration |
| R7FA6M2AF3CFP | RA6M2 series part: Cortex-M33 core, 100 MHz, 1 MB flash, no SDADC24, adds Ethernet MAC and USB FS | Targets connected industrial gateways requiring network stack offload and higher compute throughput, not precision analog acquisition | Choose only if network connectivity and >100 MHz performance outweigh need for 24-bit ADC and ultra-low-power RTC operation |
Compared with R7FA6T2BB3CNB#BA1, R7FA2A2AD3CFP offers identical analog precision and security but removes LCD driver overhead for pure control applications, while R7FA6M2AF3CFP trades SDADC24 capability for networking and higher-speed processing - making it unsuitable for metrology-critical roles.

The R7FA6T2BB3CNB#BA1 features an Arm Cortex-M23 core operating at up to 48 MHz, implementing the Armv8-M architecture with TrustZone support. It includes an 8-region Memory Protection Unit (MPU), DWT, FPB, and CoreSight™ MTB-M23 trace - all confirmed in the R01DS0418EJ0130 datasheet Rev.1.30. This architecture enables certified functional safety and secure software partitioning in the R7FA6T2BB3CNB#BA1.
Does the R7FA6T2BB3CNB#BA1 include hardware security features, and which ones are implemented?
Yes, the R7FA6T2BB3CNB#BA1 integrates AES-128/256 with ECB/CBC/CTR/GCM/CMAC/CCM cipher modes and a True Random Number Generator (TRNG). These are silicon-verified features documented in Section 1.11 of the R01DS0418EJ0130 datasheet. The R7FA6T2BB3CNB#BA1 uses these blocks for secure boot, encrypted firmware storage, and session key generation - not just software libraries.
What analog peripherals are included in the R7FA6T2BB3CNB#BA1, and how many input channels do they support?
The R7FA6T2BB3CNB#BA1 integrates a 24-bit Sigma-Delta ADC (SDADC24) with 7 differential or single-ended input channels (ANIP0–ANIP6 / ANIN0–ANIN6), plus a 12-bit successive-approximation ADC (ADC12) with 4 channels (AN000–AN003). Both converters share AVCC/AVSS supplies and support internal reference selection. This dual-ADC architecture is explicitly defined in Tables 1.7 and 1.8 of the R01DS0418EJ0130 datasheet for the R7FA6T2BB3CNB#BA1.
What package type and pin count does the R7FA6T2BB3CNB#BA1 use, and what are its I/O capabilities?
The R7FA6T2BB3CNB#BA1 uses a 100-pin LQFP package (PLQP0100KB-B, 14 mm × 14 mm, 0.5 mm pitch) with 67 general-purpose I/O pins, 3 input-only pins, and 1 output-only pin. It supports 5-V tolerant inputs on 3 pins (RTCIC0–RTCIC2) and includes 58 N-ch open-drain outputs. These mechanical and electrical I/O characteristics are specified in Table 1.11 and Figure 1.3 of the R01DS0418EJ0130 datasheet for the R7FA6T2BB3CNB#BA1.
Does the R7FA6T2BB3CNB#BA1 support independent power supply for the RTC, and what functionality does it enable?
Yes, the R7FA6T2BB3CNB#BA1 includes a dedicated VRTC pin for independent power supply to the RTC and sub-clock oscillator (SOSC). This allows calendar-mode operation (2000–2099), alarm generation, clock correction, and 1-Hz/64-Hz output - all maintained during main power loss. The VRTC domain is electrically isolated and monitored by RTCPOR circuitry, as detailed in Section 1.6 and Table 1.6 of the R01DS0418EJ0130 datasheet for the R7FA6T2BB3CNB#BA1.
