Product details
Overview
R5F11BLCAFB#30 from Renesas Electronics is a 64-pin LFQFP, 0.5 mm pitch, 64 KB flash, 5.5 KB RAM RL78/G1F 16-bit microcontroller operating from 1.6 V to 5.5 V at up to 32 MHz CPU frequency. It integrates 17-channel 8/10-bit ADC, dual 8-bit DAC, two comparators, one PGA, RTC with calendar, and supports LIN-bus via UART. It targets low-power industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F11BLCAFB#30 datasheet, R5F11BLCAFB#30 pinout, R5F11BLCAFB#30 application, or R5F11BLCAFB#30 equivalent, key selection criteria include its 0.57 μA STOP mode current, 64-pin LFQFP package with EVDD0/EVSS0 for noise-sensitive analog operation, 33-source DTC, and ELC with 22 event inputs - critical for deterministic real-time peripheral coordination in resource-constrained embedded systems.
Technical Context
The R5F11BLCAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). Its voltage regulator includes REGC capacitor support and dual power domains (VDD/EVDD0) enabling isolated analog supply for precision ADC/DAC operation.
It features a modular peripheral set including Timer Array Unit (TAU) with 4 channels, Timer RD with PWMOPA for motor control, RTC with alarm/calendar, and serial interfaces: 2 CSI, 2 I²C, 1 UART with LIN support, and IrDA. The Event Link Controller (ELC) directly routes 22 event sources to peripherals without CPU intervention, reducing latency and ISR overhead.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11BLEAFB#30 | Same 64-pin LFQFP package and peripherals, but 64 KB flash only (no 32 KB variant); identical EVDD0/EVSS0 and REGC requirements | Identical use cases; selected when full 64 KB code space required for complex protocol stacks or OTA update partitioning | Choose R5F11BLEAFB#30 when firmware size exceeds 32 KB or when future-proofing for feature expansion is needed |
| R5F11BGCAFB#30 | 48-pin LFQFP, 64 KB flash, same core/peripherals but reduced I/O (44 pins) and no EVDD0/EVSS0 - single VDD/VSS only | Suitable for cost-optimized designs where analog noise immunity is less critical and board space is constrained | Choose R5F11BGCAFB#30 when pin count and BOM cost are prioritized over analog domain isolation and maximum I/O flexibility |
Compared with R5F11BLEAFB#30, the R5F11BLCAFB#30 offers identical functionality but is the designated part number for the 32 KB flash variant in the 64-pin family - enabling memory-graded design reuse. Against R5F11BGCAFB#30, it trades 16 fewer pins for superior analog integrity via dedicated EVDD0/EVSS0, making it essential for precision sensing.

FAQ
What is the maximum CPU clock frequency supported by the R5F11BLCAFB#30?
The R5F11BLCAFB#30 supports a maximum CPU operation frequency of 32 MHz, achievable using the high-speed on-chip oscillator (±1.0% accuracy across VDD = 1.8–5.5 V and TA = −40 to +85°C). This frequency is fully validated for all operating voltage ranges and enables deterministic real-time response in time-critical control loops.
Does the R5F11BLCAFB#30 support hardware LIN bus communication?
Yes, the R5F11BLCAFB#30 supports hardware LIN bus communication via UART0, which implements LIN 2.2A protocol features including automatic sync-break detection, checksum calculation, and identifier filtering. This offloads LIN frame handling from firmware and ensures robust communication in automotive body electronics.
What are the power supply requirements for analog accuracy on the R5F11BLCAFB#30?
The R5F11BLCAFB#30 requires separate EVDD0 and EVSS0 supplies for optimal analog performance: EVDD0 must be ≥ VDD and connected to clean analog power, while EVSS0 must be tied to quiet analog ground. This separation is mandatory to achieve specified 8/10-bit ADC linearity and DAC monotonicity - mixing with digital VDD/VSS degrades SNR by >12 dB.
How many analog input channels does the R5F11BLCAFB#30 provide?
The R5F11BLCAFB#30 provides 17 analog input channels: ANI0–ANI7 (8 channels) and ANI16–ANI24 (9 channels). All channels are accessible through the 8/10-bit successive-approximation ADC with selectable reference (AVREFP/AVREFM or internal 1.45 V), supporting simultaneous sampling in burst mode for multi-sensor monitoring.
Is the R5F11BLCAFB#30 pin-compatible with other RL78/G1F 64-pin variants?
Yes, the R5F11BLCAFB#30 shares identical 64-pin LFQFP mechanical dimensions, pinout, and electrical characteristics with all other RL78/G1F 64-pin variants (e.g., R5F11BLEAFB#30), including matching EVDD0, EVSS0, REGC, and I/O assignments. Firmware and PCB layout are fully reusable across this 64-pin family regardless of flash size (32 KB vs. 64 KB).
