FAQ

What is the maximum operating frequency and supply voltage range for R5F2L36ACDFA#30?

R5F2L36ACDFA#30 operates at up to 20 MHz when supplied with 2.7–5.5 V, and supports reduced-frequency operation (5 MHz) down to 1.8 V. This dual-voltage/frequency capability enables flexible power management in battery-backed or wide-input industrial systems where R5F2L36ACDFA#30 maintains real-time responsiveness across varying rail conditions.

Does R5F2L36ACDFA#30 support hardware LIN communication?

Yes, R5F2L36ACDFA#30 integrates a dedicated hardware LIN module compliant with LIN 2.1 and SAE J2602 standards, utilizing UART0 and Timer RA. This offloads protocol framing, checksum calculation, and schedule table management from firmware - ensuring deterministic latency and freeing CPU cycles for application logic in R5F2L36ACDFA#30-based automotive body electronics or appliance sub-networks.

How many LCD segment and common pins does R5F2L36ACDFA#30 support?

R5F2L36ACDFA#30 supports up to 32 segment output pins and 8 common output pins, with integrated voltage multiplier and bias control (1/2, 1/3, 1/4). Its LCD controller drives static, 1/2, 1/3, 1/4, and 1/8 duty displays - making R5F2L36ACDFA#30 suitable for alphanumeric panels in microwave ovens, HVAC remotes, and coffee makers without external display drivers.

What low-power modes are available on R5F2L36ACDFA#30, and what are their typical currents?

R5F2L36ACDFA#30 offers wait mode (3.5 µA @ 3.0 V, 32 kHz XCIN), stop mode (2 µA), and power-off mode (0.02 µA). These modes retain RAM content and allow wake-up via external interrupt or RTC alarm - critical for R5F2L36ACDFA#30 deployments in energy-certified appliances where standby consumption must meet strict regulatory limits like Energy Star or EU ErP.

Is background operation (BGO) supported for data flash writes on R5F2L36ACDFA#30?

Yes, R5F2L36ACDFA#30 supports background operation (BGO) for data flash, allowing erase and write operations to execute concurrently with program code execution. This enables seamless field firmware updates, parameter logging, or calibration storage in R5F2L36ACDFA#30-based devices without interrupting real-time control tasks such as motor commutation or sensor polling.
