Product details
Overview
R7FA6T2AB3CFL#BA1 from Renesas is an ultra-low-power 48 MHz Arm® Cortex®-M23 microcontroller with 512-KB dual-bank flash, 48-KB SRAM, 24-bit sigma-delta ADC (4-channel), 12-bit ADC, segment LCD controller, independent RTC, and AES-128/256 encryption. It targets battery-powered industrial HMI, portable medical sensors, and smart utility meters requiring high-precision analog measurement and secure firmware updates.
For engineers reviewing the R7FA6T2AB3CFL#BA1 datasheet, R7FA6T2AB3CFL#BA1 pinout, R7FA6T2AB3CFL#BA1 application, or R7FA6T2AB3CFL#BA1 equivalent, this page delivers verified specifications, package mapping to 100-pin LQFP, functional pin roles, real-world use cases, and two validated alternative parts for design flexibility.
Technical Context
The R7FA6T2AB3CFL#BA1 implements Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight™ MTB-M23 trace. Its dual-bank flash enables seamless firmware updates via Bank Swap, while ECC-protected SRAM and Flash area protection support functional safety requirements up to IEC 61508 SIL2.
Analog subsystem integrates a 24-bit sigma-delta ADC with programmable gain amplifier (PGA), differential input support across 4 channels, and internal clocking via PLL-multiplied 32.768 kHz SOSC - enabling high-resolution sensor signal acquisition without external precision clocks. The independent power supply RTC operates from VRTC with calendar mode (2000–2099) and alarm functions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA6T2AB3CFP#AA0 | Same RA2A2 group, identical 100-pin LQFP package and 512-KB flash, but uses tray packing (AA0) vs. tape-and-reel (BA1); no functional difference | Designed for manual prototyping or low-volume assembly where reel packaging is unnecessary | Select R7FA6T2AB3CFP#AA0 for evaluation or small-batch builds; R7FA6T2AB3CFL#BA1 is optimized for automated SMT lines |
| R7FA4M2AB3CFP#AA0 | RA4M2 series part: Cortex-M33 core, 200 MHz, 1 MB flash, no SDADC24, adds USB FS and CAN FD - lacks 24-bit ADC and independent RTC | Better suited for high-speed connectivity applications (USB/CAN) but cannot replace R7FA6T2AB3CFL#BA1 in precision analog or ultra-low-power RTC-critical designs | Choose R7FA4M2AB3CFP#AA0 only when USB/CAN FD is required and 24-bit SDADC24 is not needed; not a drop-in replacement |
Compared with R7FA6T2AB3CFL#BA1, R7FA6T2AB3CFP#AA0 offers identical functionality in tray format for prototyping, while R7FA4M2AB3CFP#AA0 trades 24-bit analog capability and independent RTC for higher performance and connectivity - making it unsuitable for precision metering or battery-backed timekeeping.

FAQ
What is the maximum operating frequency and core architecture of the R7FA6T2AB3CFL#BA1?
The R7FA6T2AB3CFL#BA1 features an Arm Cortex-M23 core operating at up to 48 MHz, compliant with the Armv8-M architecture. It includes an 8-region Memory Protection Unit (MPU), single-cycle integer multiplier, and CoreSight™ MTB-M23 trace - enabling deterministic real-time control and secure partitioning for functional safety applications.
Does the R7FA6T2AB3CFL#BA1 support firmware updates without interrupting system operation?
Yes, the R7FA6T2AB3CFL#BA1 supports seamless firmware updates via Bank Swap functionality across its dual-bank 512-KB flash memory. This allows one bank to execute while the other is reprogrammed, ensuring zero downtime - critical for unattended industrial and medical devices where rebooting is unacceptable.
What analog capabilities does the R7FA6T2AB3CFL#BA1 provide for precision sensor interfacing?
The R7FA6T2AB3CFL#BA1 integrates a 24-bit sigma-delta ADC (SDADC24) with 4 differential input channels, programmable gain amplifier, and internal PLL clocking from the 32.768 kHz sub-oscillator. It also includes a 12-bit ADC (4 channels) and on-chip temperature sensor - delivering high-resolution, low-noise acquisition for strain gauges, thermistors, and medical biosensors.
How does the independent power supply RTC in the R7FA6T2AB3CFL#BA1 function during main power loss?
The R7FA6T2AB3CFL#BA1 includes an independent power supply RTC powered by the VRTC pin, allowing continuous timekeeping from a backup battery or supercapacitor even when main VCC is disconnected. It supports calendar mode (2000–2099), alarm interrupts, and automatic leap-year correction - eliminating the need for external RTC ICs.
Is the R7FA6T2AB3CFL#BA1 pin-compatible with other RA2A2 family members?
The R7FA6T2AB3CFL#BA1 shares the same 100-pin LQFP package and pinout with other RA2A2 100-pin variants like R7FA2A2AD3CFP, but differs in SDADC24 channel count (4 vs. 7) and feature set. Pin compatibility is confirmed for shared peripherals (SCI, I2C, SPI, GPT), though SDADC24 and LCD pin allocations match only within the same variant group.
