Renesas R5F11BCCGLA#U0

Overview

R5F11BCCGLA#U0 from Renesas Electronics is a 36-pin WFLGA-packaged RL78/G1F 16-bit microcontroller with 32 KB flash, 4 KB data flash, 5.5 KB RAM, and operation from 1.6 V to 5.5 V. It integrates an 8/10-bit ADC (15 channels), dual 8-bit DAC outputs, two comparators, one PGA, RTC with calendar, and supports LIN-bus via UART. Used in battery-powered industrial sensor nodes requiring ultra-low power and analog integration.

For engineers reviewing the R5F11BCCGLA#U0 datasheet, R5F11BCCGLA#U0 pinout, R5F11BCCGLA#U0 application, or R5F11BCCGLA#U0 equivalent, key selection criteria include its −40°C to +105°C industrial temperature grade, 36-pin 4×4 mm WFLGA package, 32 MHz max CPU speed, HALT/STOP/SNOOZE low-power modes, and integrated analog peripherals enabling compact, single-chip sensing solutions.

Technical Context

The R5F11BCCGLA#U0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It features a high-accuracy ±1.0% on-chip oscillator (1–32 MHz) and low-speed 15 kHz internal oscillator for RTC and watchdog timing.

Its peripheral set includes Timer Array Unit (TAU) with 4 channels, Timer RD (2 channels with PWMOPA), Timer RG (1), Timer RX (1), and event-driven control via Event Link Controller (ELC) supporting 21 input events and 10 trigger outputs - enabling deterministic real-time response without CPU polling.

FAQ

What is the maximum operating frequency and voltage range supported by the R5F11BCCGLA#U0?

The R5F11BCCGLA#U0 operates at up to 32 MHz CPU frequency with a supply voltage range of 1.6 V to 5.5 V for industrial-grade operation (−40°C to +105°C). Its high-accuracy on-chip oscillator maintains ±1.0% tolerance across this voltage and temperature range, eliminating need for external crystal in many applications. The R5F11BCCGLA#U0 also supports subsystem clocking at 32.768 kHz for RTC and low-power timing.

Does the R5F11BCCGLA#U0 support LIN bus communication, and how is it implemented?

Yes, the R5F11BCCGLA#U0 supports LIN bus communication through its UART0 peripheral, which includes dedicated LINSEL pin functionality for automatic sync-break detection and checksum handling. The R5F11BCCGLA#U0's UART0 operates in LIN mode with configurable baud rates and supports both master and slave roles. Its integrated ELC allows LIN frame reception to trigger DMA transfers or timer actions without CPU intervention.

How many analog-to-digital converter channels does the R5F11BCCGLA#U0 provide, and what resolutions are supported?

The R5F11BCCGLA#U0 provides 15 analog input channels with selectable 8-bit or 10-bit resolution. It supports internal reference voltage (1.45 V) and temperature sensor, and allows simultaneous sampling across multiple channels using hardware triggers. The R5F11BCCGLA#U0's ADC conversion time is 1.2 μs per sample at 10-bit resolution, enabling high-speed sensor acquisition in real-time control loops.

What low-power modes are available on the R5F11BCCGLA#U0, and what is the typical current consumption in each?

The R5F11BCCGLA#U0 offers HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD enabled), and SNOOZE modes. In STOP mode, the RTC continues running with calendar function and alarm wake-up while preserving RAM contents. The R5F11BCCGLA#U0 achieves 0.57 μA at 25°C with VDD = 3.0 V, meeting stringent battery-life requirements for industrial wireless sensors.

Is the R5F11BCCGLA#U0 pin-compatible with other RL78/G1F variants, and what package options exist?

The R5F11BCCGLA#U0 uses a 36-pin WFLGA (4×4 mm, 0.5 mm pitch) package and is pin-compatible with R5F11BCEGLA#U0 (64 KB flash variant) in the same package. It is not pin-compatible with 32-pin HWQFN or 48-pin LFQFP variants due to differing pin counts and functions. The R5F11BCCGLA#U0's #U0 suffix indicates tray packaging for WFLGA, and its exposed die pad must be connected to VSS for thermal and electrical stability.
