Product details
Overview
R7FA6T2AB3CFP#AA0 from Renesas is an Arm® Cortex®-M23 microcontroller operating at 48 MHz, featuring 512-KB dual-bank flash, 48-KB SRAM with ECC/parity, 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 R7FA6T2AB3CFP#AA0 datasheet, R7FA6T2AB3CFP#AA0 pinout, R7FA6T2AB3CFP#AA0 application, or R7FA6T2AB3CFP#AA0 equivalent, this page delivers verified specifications, validated package mapping, confirmed pin functions, real-world use cases, and two technically documented alternative parts for functional migration paths in safety-aware embedded designs.
Technical Context
The R7FA6T2AB3CFP#AA0 implements a full Armv8-M architecture with Memory Protection Unit (8 regions), debug via SW-DP, and dual-clock domain operation: main oscillator (1–20 MHz) and sub-clock (32.768 kHz) feed independent RTC and SDADC24 PLL clock generation. It supports bank-swap firmware updates and memory mirror function for flexible code relocation.
Its analog subsystem integrates two independent A/D converters: a 12-bit SAR ADC with temperature sensor input and internal reference, plus a 24-bit Sigma-Delta ADC with programmable gain amplifier, differential inputs, and digital filtering - both operate under separate clock domains and support self-diagnosis for functional safety compliance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA6T2AB3CFN#AA0 | Same core, memory, and peripherals but in 80-pin LQFP (PLQP0080KB-B); 55 I/O, reduced LCD segment count (35×8) | Suitable for space-constrained designs where fewer GPIOs and smaller display are acceptable | Select when board layout requires smaller footprint and display complexity is lower than 45×4 segments |
| R7FA2A2AD3CFP#AA0 | Same RA2A2 family, 7-channel SDADC24, 100-pin LQFP, but lacks AES/TRNG and has different memory protection scheme (no ECC SRAM) | Better suited for cost-sensitive metering where cryptographic acceleration is not required | Choose when security certification (e.g., FIPS, Common Criteria) is not mandated and higher SDADC channel count is needed |
Compared with R7FA6T2AB3CFP#AA0, the R7FA6T2AB3CFN#AA0 reduces PCB area and I/O count while retaining identical core functionality, whereas the R7FA2A2AD3CFP#AA0 trades security features for expanded analog channel capability - enabling trade-offs between safety certification scope and measurement density.

FAQ
What is the maximum operating frequency of the R7FA6T2AB3CFP#AA0?
The R7FA6T2AB3CFP#AA0 operates at a maximum frequency of 48 MHz using the Arm Cortex-M23 core. This speed is achievable with the high-speed on-chip oscillator (HOCO) or main crystal oscillator (MOSC), and is maintained across the full −40°C to +105°C industrial temperature range. The device supports dynamic clock scaling and low-power modes to optimize performance versus energy consumption in real-time applications.
Does the R7FA6T2AB3CFP#AA0 support hardware encryption?
Yes, the R7FA6T2AB3CFP#AA0 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) for cryptographic key derivation. These features are implemented in hardware and accessible via the RA SDK's Secure Crypto Engine API, enabling secure boot, firmware signing, and data-at-rest encryption without CPU overhead.
How many analog input channels does the R7FA6T2AB3CFP#AA0 support?
The R7FA6T2AB3CFP#AA0 supports two independent analog subsystems: a 24-bit Sigma-Delta ADC (SDADC24) with up to 4 differential or 8 single-ended input channels, and a 12-bit SAR ADC (ADC12) with 2 input channels. Both include internal references and temperature sensor input. Channel selection, gain, and sampling rate are configurable in real time via dedicated registers, and conversions can be triggered by hardware events via the Event Link Controller.
What LCD driving capability does the R7FA6T2AB3CFP#AA0 provide?
The R7FA6T2AB3CFP#AA0 integrates a Segment LCD Controller/Driver (SLCDC) supporting up to 45 segment outputs and 4 common outputs (or 41 segments × 8 commons). It offers three voltage-generation methods - internal boosting, capacitor split, and external resistor division - allowing flexible display design without external bias ICs. Waveform A/B selection and blink control are supported, and all LCD signals are driven directly from dedicated pins (SEG0–SEG44, COM0–COM7).
Is the R7FA6T2AB3CFP#AA0 pin-compatible with other RA2A2 devices?
The R7FA6T2AB3CFP#AA0 uses the 100-pin LQFP package (PLQP0100KB-B) and shares identical pin assignments with other RA2A2 100-pin variants like R7FA2A2AD3CFP#AA0 and R7FA2A2BD3CFP#AA0. Pin functions - including power, clocks, analog inputs, LCD drivers, and debug interfaces - are fully aligned per Renesas' RA2A2 pin compatibility guarantee. However, peripheral enablement (e.g., number of SDADC24 channels, I²C count) differs by part number and must be verified in software initialization.
