Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power Arm Cortex-M23 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA2A2BD3CFM | Same RA2A2 family, identical 64-pin LQFP package, 4-channel SDADC24, but lacks security features (no AES/TRNG) and has reduced I/O count (39 vs 39 same, but fewer SCI channels: 4 vs 5). | Suitable for cost-sensitive industrial controls where cryptographic security is not mandated and UART-based communication suffices. | Select when security certification is unnecessary and BOM cost reduction is prioritized over future-proofing for secure firmware updates. |
| R7FA4M2AB3CFM | RA4M2 series; 48 MHz Cortex-M33 core, 512-KB flash, 128-KB SRAM, but no SDADC24 or SLCDC; includes USB FS, more advanced security (TrustZone, secure boot). | Better suited for USB-connected edge nodes requiring higher compute throughput and secure connectivity-but requires external LCD driver and precision ADC. | Choose when system architecture demands USB host/device capability and hardware-enforced TrustZone isolation, accepting added component count for analog/LCD functions. |
Compared with R7FA6T2AB3CFM#BA1, R7FA2A2BD3CFM offers identical packaging and analog capability at lower cost but omits essential security blocks, while R7FA4M2AB3CFM trades integrated analog/LCD for enhanced compute and USB-requiring external components to match the full feature set.

Combined with dual-bank flash memory, it enables authenticated, encrypted over-the-air (OTA) updates where one bank runs active firmware while the other validates and writes new code-ensuring zero-downtime and tamper resistance.
What analog peripherals are included in the R7FA6T2AB3CFM#BA1, and what are their key specifications?
The R7FA6T2AB3CFM#BA1 integrates two ADCs: a 24-bit sigma-delta converter (SDADC24) with 4 differential channels, 7.813 kHz max sampling rate, and programmable gain amplifier; and a 12-bit successive approximation ADC (ADC12) with 4 input channels and on-chip temperature sensor support. Both converters share dedicated analog supplies (AVCC/AVSS) and reference pins for noise-immune precision measurement.
How does the Segment LCD Controller (SLCDC) in the R7FA6T2AB3CFM#BA1 operate, and what display configurations does it support?
The R7FA6T2AB3CFM#BA1's SLCDC supports up to 41 segment × 8 common or 21 segment × 4 common LCDs using switchable internal voltage boosting, capacitor-split, or external resistor-divider bias methods. It provides configurable waveform A/B outputs, blink control, and independent VL1–VL4/CAPH/CAPL pins-eliminating need for external LCD bias ICs in compact, low-power HMI designs.
What low-power features does the R7FA6T2AB3CFM#BA1 offer for battery-operated applications?
The R7FA6T2AB3CFM#BA1 delivers ultra-low power operation via multiple autonomous peripherals: 32-bit AGTW timers maintain precise wake-up intervals in deep sleep (<1 μA), Event Link Controller (ELC) enables hardware-triggered data transfers without CPU, and Data Transfer Controller (DTC) handles ADC/DMA operations autonomously. Its 1.6–5.5 V operating range and -40°C to +105°C rating ensure robustness across diverse battery-powered environments.
