Product details
Overview
R7FA6T2BB3CFP#BA0 from Renesas is an Arm® Cortex®-M23 microcontroller operating at 48 MHz, featuring 512-KB dual-bank flash, 48-KB SRAM with ECC/parity split, 24-bit Sigma-Delta ADC (4-channel), 12-bit ADC (2-channel), and integrated Segment LCD controller supporting up to 45 segments × 4 commons - designed for ultra-low-power industrial HMI and metering applications.
For engineers reviewing the R7FA6T2BB3CFP#BA0 datasheet, R7FA6T2BB3CFP#BA0 pinout, R7FA6T2BB3CFP#BA0 application, or R7FA6T2BB3CFP#BA0 equivalent, key selection criteria include SDADC24 channel count, LQFP-100 package compatibility, independent RTC with VRTC supply, AES-128/256 security, and low-voltage detection across VCC/VRTC/EXLVDVBAT rails.
Technical Context
This MCU implements Armv8-M architecture with Memory Protection Unit (8 regions), CoreSight™ MTB-M23 trace, and SW-DP debug interface. It integrates dual-bank flash for safe firmware updates and Memory Mirror Function (MMF) enabling seamless image relocation without code modification.
Analog subsystem includes two independent A/D converters: SDADC24 supports differential/single-ended inputs at 3.906–7.813 kHz sampling with programmable gain amplifier and internal clock sources (MOSC, PLL-multiplied SOSC); ADC12 provides 4-channel conversion with temperature sensor and internal reference support.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA2A2AD3CFP | Same RA2A2 family, 7-channel SDADC24, identical 100-pin LQFP package and memory configuration | Supports higher-channel analog sensor arrays (e.g., multi-phase energy meters) | Select when >4 SDADC24 channels are required; otherwise R7FA6T2BB3CFP#BA0 offers optimal cost/power balance for 4-channel use cases |
| R7FA6M2AF3CFP | RA6M2 series, Cortex-M33 core, 100 MHz, 1 MB flash, no SDADC24, adds Ethernet and USB FS | Targets connected industrial gateways requiring network stack offload and higher compute throughput | Choose only if Ethernet/USB connectivity and >48 MHz performance are mandatory; lacks SDADC24 and independent RTC power domain |
Compared with R7FA2A2AD3CFP, R7FA6T2BB3CFP#BA0 reduces SDADC24 channel count but maintains identical package, security, and low-power features - ideal for cost-sensitive 4-channel metering. Versus R7FA6M2AF3CFP, it trades raw performance and connectivity for superior analog precision and RTC autonomy.

FAQ
What is the SDADC24 channel count supported by R7FA6T2BB3CFP#BA0?
R7FA6T2BB3CFP#BA0 supports 4 differential or single-ended channels on its 24-bit Sigma-Delta ADC (SDADC24). This is confirmed in the RA2A2 product list (Table 1.12) and function comparison table (Table 1.13), where R7FA6T2BB3CFP#BA0 is designated as a "B"-variant part with SDADC24 4 ch - distinct from the 7-channel "A"-variant.
Does R7FA6T2BB3CFP#BA0 include hardware encryption acceleration?
Yes, R7FA6T2BB3CFP#BA0 integrates a dedicated AES engine supporting ECB, CBC, CTR, GCM, CMAC, and CCM cipher modes with 128-bit and 256-bit key lengths. It also includes a True Random Number Generator (TRNG) for cryptographic key derivation - both features are explicitly listed in the Security section of the datasheet (R01DS0418EJ0130).
What LCD configurations does the SLCDC in R7FA6T2BB3CFP#BA0 support?
The Segment LCD Controller (SLCDC) in R7FA6T2BB3CFP#BA0 supports two configurations: 45 segment signals × 4 common signals or 41 segment signals × 8 common signals. Voltage drive methods - internal boosting, capacitor split, and external resistance division - are selectable per application needs, as specified in Table 1.9 and Figure 1.3 pin assignment.
Is R7FA6T2BB3CFP#BA0 pin-compatible with other RA2A2 MCUs in 100-pin LQFP?
Yes, R7FA6T2BB3CFP#BA0 shares the same 100-pin LQFP package (PLQP0100KB-B) and pinout as other RA2A2 100-pin variants including R7FA2A2AD3CFP and R7FA2A2BD3CFP. Pin assignments in Figure 1.3 and Figure 1.4 confirm identical physical layout and signal mapping across all 100-pin members of the RA2A2 group.
What power supply domains does R7FA6T2BB3CFP#BA0 support for RTC operation?
R7FA6T2BB3CFP#BA0 features an independent power supply domain for the RTC, accessed via the VRTC pin. This allows the RTC to retain calendar, alarm, and clock correction functions even when main VCC is powered down - a capability enabled by dedicated circuitry including RTCPOR and RTCIC0–RTCIC2 time-capture inputs, as detailed in Section 1.6 and Table 1.14.
