Product details
Overview
R5F100LCAFA#30 from Renesas is a 64-pin LQFP-0.65mm, 512 KB flash, 8 KB data flash, 32 KB RAM RL78/G13 16-bit microcontroller operating from 1.6–5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), used in battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F100LCAFA#30 datasheet, R5F100LCAFA#30 pinout, R5F100LCAFA#30 application, or R5F100LCAFA#30 equivalent, key selection criteria include integrated RTC with calendar/alarm, 26-channel 10-bit ADC with internal temperature sensor, dual UART/LIN support, and hardware BGO for concurrent code execution during data flash rewriting.
Technical Context
The R5F100LCAFA#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with 99-year calendar and clock correction, and watchdog timer with dedicated low-speed on-chip oscillator.
Its peripheral set includes up to 16 channels of 16-bit timer, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, 2–8 CSI (SPI-compatible) channels, and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM - all optimized for deterministic real-time response in resource-constrained embedded systems.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LCAFA#30?
The R5F100LCAFA#30 operates at up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation. This frequency range enables both high-throughput control loops and extended battery life in the same device.
Does the R5F100LCAFA#30 support in-system programming and secure firmware updates?
Yes, the R5F100LCAFA#30 supports in-system programming via its on-chip debug function and self-programming capability, including boot swap and flash shield window features. These mechanisms allow safe, atomic firmware updates and protect against unauthorized code modification - essential for certified industrial and metering applications where security and reliability are mandated.
What are the key low-power modes available on the R5F100LCAFA#30 and their typical current consumption?
The R5F100LCAFA#30 offers HALT mode (66 μA/MHz), STOP mode (0.57 μA with RTC and LVD active), and SNOOZE mode. STOP mode retains RTC calendar, alarm, and LVD monitoring while minimizing power - ideal for battery-backed real-time logging. HALT mode preserves full register and RAM content while stopping the CPU clock, enabling fast wake-up for event-driven applications.
Can the R5F100LCAFA#30 interface directly with 1.8 V or 2.5 V peripherals?
Yes, the R5F100LCAFA#30 supports different-potential interface operation: its I/O ports can be configured to connect directly to 1.8 V, 2.5 V, or 3 V devices without external level shifters. This is enabled by configurable input buffer thresholds and voltage-tolerant pins, simplifying mixed-voltage system design and reducing BOM cost in sensor-rich embedded nodes.
How many serial communication interfaces does the R5F100LCAFA#30 integrate, and what protocols do they support?
The R5F100LCAFA#30 integrates up to 10 serial channels: 2–4 UART/LIN interfaces (supporting LIN 2.2 physical layer), 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels. These share pin resources flexibly, allowing simultaneous use of UART for modem comms, I²C for EEPROM/sensors, and CSI for displays or ADCs - all without external protocol translators.
