Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum operating frequency of the R7FA6T2AB3CFL#AA1?
The R7FA6T2AB3CFL#AA1 operates at a maximum frequency of 48 MHz using its Arm Cortex-M23 core. This speed is achievable with the high-speed on-chip oscillator (HOCO) at 48 MHz or via PLL multiplication from the main or sub-clock oscillators. The core maintains full performance across the full industrial temperature range (−40°C to +105°C) and supply voltage (1.6 V to 5.5 V).
Does the R7FA6T2AB3CFL#AA1 support hardware-accelerated cryptography?
Yes, the R7FA6T2AB3CFL#AA1 integrates a dedicated AES engine supporting ECB, CBC, CTR, GCM, CMAC, and CCM modes with 128-bit and 256-bit key lengths. It also includes a True Random Number Generator (TRNG) compliant with NIST SP 800-90B for cryptographic key derivation. These features are accessible via Renesas' Secure Crypto Engine API and require no external co-processor.
How many analog input channels does the 24-bit SDADC24 support on the R7FA6T2AB3CFL#AA1?
The R7FA6T2AB3CFL#AA1's 24-bit Sigma-Delta ADC (SDADC24) supports up to 4 differential analog input channels (ANIP0–ANIP3 / ANIN0–ANIN3), as confirmed by Renesas documentation for the "B" variant of the RA2A2 group. This matches the "B" designation in the part number and distinguishes it from the 7-channel "A" variant.
What LCD configurations are supported by the R7FA6T2AB3CFL#AA1's SLCDC?
The R7FA6T2AB3CFL#AA1's Segment LCD Controller (SLCDC) supports two configurations: 45 segment outputs with 4 common outputs (when 8-com is not used), or 41 segment outputs with 8 common outputs (when 8-com is enabled). Voltage generation is configurable via internal boosting, capacitor split, or external resistor division methods - all controlled in hardware without CPU overhead.
Is the R7FA6T2AB3CFL#AA1 pin-compatible with other RA2A2 family members?
The R7FA6T2AB3CFL#AA1 uses the 100-pin LQFP package (PLQP0100KB-B) and shares identical pin assignments with other 100-pin RA2A2 variants like R7FA2A2AD3CFP and R7FA2A2BD3CFP. However, functional differences exist - notably the SDADC24 channel count (4 vs. 7) and I²C channel count (1 vs. 2) - so firmware and schematic review is required before substitution.
