FAQ
What is the maximum operating frequency and core architecture of the R7FA6T2BD3CNE#AA1?
The R7FA6T2BD3CNE#AA1 features an Arm Cortex-M23 core operating at up to 48 MHz, implementing the Armv8-M architecture with TrustZone-ready execution, 8-region Memory Protection Unit (MPU), and SW-DP debug interface. This architecture enables secure, deterministic real-time operation ideal for certified industrial and medical applications where memory isolation and debug visibility are critical. The R7FA6T2BD3CNE#AA1 achieves this performance while maintaining ultra-low active and sleep-mode power consumption.
Does the R7FA6T2BD3CNE#AA1 support hardware encryption and secure key generation?
Yes, the R7FA6T2BD3CNE#AA1 integrates dedicated hardware AES engines supporting ECB, CBC, CTR, GCM, CMAC, and CCM modes with 128- and 256-bit keys, plus a True Random Number Generator (TRNG) compliant with NIST SP 800-90B. These blocks operate independently of the CPU, enabling fast, side-channel-resistant cryptographic operations for secure boot, firmware authentication, and encrypted data logging-all without consuming CPU cycles. The R7FA6T2BD3CNE#AA1 leverages these features to meet IEC 62443 and Common Criteria functional requirements.
How many analog-to-digital converter channels does the R7FA6T2BD3CNE#AA1 provide, and what are their resolutions?
The R7FA6T2BD3CNE#AA1 integrates two distinct ADC subsystems: a 24-bit Sigma-Delta ADC (SDADC24) with four fully differential input channels, and a 12-bit successive-approximation ADC (ADC12) with four single-ended inputs plus on-chip temperature sensor (TSN) and internal reference support. The SDADC24 operates at selectable sampling rates (7.813/8.333 kHz or 3.906/4.166 kHz) and includes a programmable gain amplifier, making it suitable for high-precision, low-noise sensor interfaces such as load cells and thermopiles. Both converters are independently configurable and can operate concurrently.
What LCD driving capability does the R7FA6T2BD3CNE#AA1 offer, and how is it configured?
The R7FA6T2BD3CNE#AA1 includes a Segment LCD Controller/Driver (SLCDC) supporting up to 45 segments × 4 commons or 41 segments × 8 commons, with configurable drive methods: internal voltage boosting, capacitor-split, or external resistor division. Voltage references VL1–VL4 and capacitor pins CAPH/CAPL allow flexible biasing, while waveform A/B selection enables optimized contrast and flicker reduction. This integrated capability eliminates external LCD driver ICs, reduces BOM cost, and simplifies layout-especially valuable in space-constrained portable and metering applications using the R7FA6T2BD3CNE#AA1.
What package type and pin count does the R7FA6T2BD3CNE#AA1 use, and are there pin-compatible variants?
The R7FA6T2BD3CNE#AA1 uses a 100-pin LQFP package (PLQP0100KB-B), 14 mm × 14 mm, 0.5 mm pitch, with 67 general-purpose I/O pins (including 3 input-only and 1 output-only), 2 five-volt tolerant pins, and dedicated analog, RTC, debug, and LCD signal routing. It is pin-compatible with other RA2A2 100-pin variants like R7FA2A2AD3CFP (7-channel SDADC24) and R7FA2A2BD3CFP (same 4-channel SDADC24), enabling scalable design reuse across performance tiers without PCB redesign.
