Pinout & Package
64-pin LQFP (PLQP0064KB-C), 10 mm × 10 mm, 0.5 mm pitch, with exposed thermal pad (not electrically connected). Pin functions include dedicated SDADC24 analog inputs (ANIP0–ANIP3, ANIN0–ANIN3), LCD segment/common drivers (SEG0–SEG21, COM0–COM7), and hardware security interfaces (SWDIO/SWCLK).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual-domain power: VCC powers digital core; AVCC/AVSS isolate analog circuits to minimize noise coupling into SDADC24. |
| ANIP0–ANIP3, ANIN0–ANIN3 | SDADC24 analog inputs | Four fully differential 24-bit input channels - enable high-accuracy current/voltage sensing without external signal conditioning. |
| SEG0–SEG21, COM0–COM7 | LCD driver outputs | Configurable for 21-seg × 4-com or 17-seg × 8-com drive - supports direct connection to segment-type displays in energy meters. |
| SWDIO / SWCLK | Debug interface | 2-pin Serial Wire Debug - allows full programming, trace, and real-time debugging without dedicated JTAG pins. |
| RTCIC0–RTCIC2, VRTC | RTC event capture & backup supply | Independent VRTC rail + three RTC input capture pins - enable tamper detection and battery-backed time stamping. |
Key Features
| Feature | Design Value |
|---|---|
| Bank Swap Flash | Enables seamless firmware updates by swapping active code banks - eliminates runtime interruption during field upgrades. |
| Memory Mirror Function (MMF) | Maps application image load address to fixed link address - simplifies bootloader development and reduces memory fragmentation. |
| ELC + DTC Co-processing | Permits autonomous peripheral chaining (e.g., SDADC24 → DTC → SRAM) - offloads CPU for continuous sensor logging at ultra-low power. |
| Independent Power Supply RTC | Maintains calendar time and alarm functions on separate VRTC rail - ensures accurate timekeeping during main power brownouts. |
| ECC-Protected SRAM | 16 KB of SRAM with error correction coding - prevents silent data corruption in safety-critical applications like industrial control. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 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 count, but fewer pull-up resistors: 37 vs 37). | Targeted at cost-sensitive industrial controls where cryptographic security is not required. | Select when security certification (e.g., FIPS, IEC 62443) is unnecessary and BOM cost reduction is prioritized. |
| R7FA4M2AD3CFM | RA4M2 series part in same 64-pin LQFP; features Arm Cortex-M33 core, 200 MHz, 512 KB flash, but no SDADC24 or segment LCD controller - replaces analog/HMI functionality with USB and higher-speed peripherals. | Suitable for gateway-class devices requiring USB host/device, Ethernet MAC, or enhanced connectivity over precision analog capability. | Choose when system requires USB/USB-CDC or advanced comms over high-resolution analog acquisition and integrated display driving. |
Compared with R7FA6T2BB3CFM#BA0, R7FA2A2BD3CFM offers identical packaging and analog capability but omits security IP, while R7FA4M2AD3CFM trades SDADC24 and SLCDC for higher compute and connectivity - making each suitable for distinct segments of industrial edge design.

FAQ
What is the maximum operating frequency of the R7FA6T2BB3CFM#BA0?
The R7FA6T2BB3CFM#BA0 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 sub-clock oscillator. The core supports deterministic real-time execution with single-cycle integer multiply and 19-cycle divide operations - critical for time-sensitive metrology tasks in the R7FA6T2BB3CFM#BA0.
Does the R7FA6T2BB3CFM#BA0 support secure boot and cryptographic operations?
Yes, the R7FA6T2BB3CFM#BA0 includes hardware-accelerated AES-128/256 encryption supporting ECB, CBC, CTR, GCM, CMAC, and CCM modes, plus a True Random Number Generator (TRNG). These features enable secure boot validation, encrypted firmware updates, and authenticated communication - all implemented without software overhead. The R7FA6T2BB3CFM#BA0 leverages these blocks to meet IEC 62443-3-3 SL2 requirements when properly configured.
How many analog input channels does the R7FA6T2BB3CFM#BA0 provide for high-resolution measurement?
The R7FA6T2BB3CFM#BA0 integrates a 24-bit Sigma-Delta A/D Converter (SDADC24) with four fully differential input channels (ANIP0–ANIP3 / ANIN0–ANIN3), plus a separate 12-bit successive-approximation ADC (ADC12) with four channels. The SDADC24 supports programmable gain amplification and operates with sampling rates of 3.906/4.166 kHz or 7.813/8.333 kHz - delivering >110 dB SNR for precision current/voltage sensing in the R7FA6T2BB3CFM#BA0.
What LCD driving capability does the R7FA6T2BB3CFM#BA0 offer?
The R7FA6T2BB3CFM#BA0 includes a Segment LCD Controller/Driver (SLCDC) supporting up to 21 segment signals and 4 common signals (or 17 segments × 8 commons) - configurable for direct drive of multiplexed segment-type displays used in energy meters and panel instruments. It supports internal voltage boosting, capacitor-split, and external resistor-divider bias methods, and includes blink control - eliminating need for external LCD driver ICs in the R7FA6T2BB3CFM#BA0 design.
Is the R7FA6T2BB3CFM#BA0 pin-compatible with other RA2A2 family members?
No, the R7FA6T2BB3CFM#BA0 is not pin-compatible with other RA2A2 variants. While it shares the 64-pin LQFP package (PLQP0064KB-C) with R7FA2A2BD3CFM, differences in SDADC24 channel count, security feature allocation, and I/O configuration mean PCB layout cannot be reused. Pin assignments for analog inputs (ANIP/ANIN), LCD outputs (SEG/COM), and security interfaces are unique to the R7FA6T2BB3CFM#BA0 per Renesas R01DS0418EJ0130.
