Renesas R5F11BLCGFB#30

Overview

R5F11BLCGFB#30 from Renesas Electronics is a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), industrial-grade RL78/G1F 16-bit microcontroller with 32 KB flash, 4 KB data flash, 5.5 KB RAM, and operation from −40 to +105°C. It integrates an 8/10-bit ADC (17 channels), dual 8-bit DACs, two comparators, one PGA, nine 16-bit timers (including RTC and PWMOPA), and multiple serial interfaces (CSI, UART/LIN, I²C, IrDA) for embedded control in power-constrained environments.

For engineers reviewing the R5F11BLCGFB#30 datasheet, R5F11BLCGFB#30 pinout, R5F11BLCGFB#30 application, or R5F11BLCGFB#30 equivalent, key selection criteria include its true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V supply range, on-chip debug support, self-programming with boot swap, and industrial temperature qualification (G-grade).

Technical Context

The R5F11BLCGFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). Its memory subsystem includes 32 KB code flash (1 KB blocks), 4 KB background-operable data flash (1M rewrite cycles), and 5.5 KB RAM - with BCD correction and multiply-accumulate instructions supporting real-time control math.

Peripherals are orchestrated via Event Link Controller (22 event inputs, 10 trigger outputs) and Data Transfer Controller (33 activation sources), enabling autonomous peripheral coordination without CPU intervention. Power management includes HALT, STOP, and SNOOZE modes, plus on-chip POR and 14-level LVD with interrupt/reset selection.

FAQ

What is the operating voltage range and temperature grade of the R5F11BLCGFB#30?

The R5F11BLCGFB#30 operates from 1.6 V to 5.5 V at −40 to +105°C (industrial G-grade). Its on-chip voltage detector supports 8 selectable LVD levels for brown-out protection in harsh environments. This wide voltage range allows direct connection to single-cell Li-ion or multi-cell alkaline batteries without external regulators, while the extended temperature rating ensures reliability in motor drives and outdoor metering equipment.

Does the R5F11BLCGFB#30 support in-system programming and secure firmware updates?

Yes, the R5F11BLCGFB#30 supports full in-system programming via its on-chip debug interface and includes self-programming features such as boot swap function and flash shield window. These capabilities allow secure, field-upgradable firmware with protected code regions - critical for certified medical or utility applications where firmware integrity must be maintained across product lifetime.

How many analog-to-digital converter channels does the R5F11BLCGFB#30 provide, and what resolution options are available?

The R5F11BLCGFB#30 integrates an 8/10-bit successive approximation ADC with 17 input channels (ANI0–ANI7, ANI16–ANI24). It supports internal 1.45 V reference voltage and on-chip temperature sensor, enabling accurate voltage, current, and thermal measurements without external references. The selectable resolution allows optimization between speed (8-bit) and precision (10-bit) depending on application requirements.

What serial communication interfaces are integrated into the R5F11BLCGFB#30, and which support LIN bus protocol?

The R5F11BLCGFB#30 integrates three UART modules, two of which support LIN bus protocol (UART0 with LINSEL pin). It also provides two CSI (SPI-like) channels, three I²C channels, and one IrDA transceiver. All interfaces are remappable via Peripheral I/O Redirection Registers (PIOR0–PIOR3), allowing flexible PCB layout and reuse of pins for multiple functions without hardware changes.

What packaging and pin configuration does the R5F11BLCGFB#30 use, and how is analog noise isolation addressed?

The R5F11BLCGFB#30 uses a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch) package with dedicated EVDD0 and EVSS0 pins for analog power and ground. Renesas recommends separating EVDD0/EVSS0 from VDD/VSS and routing them to quiet analog ground planes - a design practice that reduces digital switching noise coupling into ADC/DAC paths and improves measurement accuracy in sensor applications.
