Renesas R5F11CCCGBG#W0

Overview

R5F11CCCGBG#W0 from Renesas Electronics is a 36-pin TFBGA-packaged RL78/I1E 16-bit microcontroller designed for high-precision analog sensing in industrial temperature environments (−40 to +105°C). It integrates a 24-bit ΔΣ A/D converter (SNDR: 85 dB), 3-channel programmable-gain instrumentation amplifier (x1–x64), 8 KB RAM, 32 KB code flash, and 4 KB data flash with 1M-cycle endurance. It targets sensor signal conditioning in smart transmitters and battery-powered industrial monitors.

For engineers reviewing the R5F11CCCGBG#W0 datasheet, R5F11CCCGBG#W0 pinout, R5F11CCCGBG#W0 application, or R5F11CCCGBG#W0 equivalent, key selection criteria include its 4-channel PGA input support, SBIAS bias output for MEMS sensors, real-time clock with calendar function, ultra-low-power STOP/HALT modes, and compatibility with LIN-bus UART for automotive-grade diagnostics.

Technical Context

The R5F11CCCGBG#W0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.03125 μs at 32 MHz). Its analog front-end includes a dedicated voltage regulator (REGA/REGC), AVDD/AVSS isolation, and switchable operational amplifier matrix supporting up to three independent amplifiers - one must be configured as a voltage follower per datasheet Note 1.

It supports dual-clock domain operation: high-speed on-chip oscillator (1–32 MHz, ±2.0% accuracy) and PLL-derived system clock (up to 64 MHz), with hardware event linking via ELC and background data flash rewriting using DTC-triggered BGO. The 36-pin TFBGA layout enables compact placement while maintaining full access to 14 I/O pins including 10 analog-capable channels (ANI0–ANI9, ANX0–ANX5).

FAQ

What is the maximum operating frequency of the R5F11CCCGBG#W0's high-speed on-chip oscillator?

The R5F11CCCGBG#W0 supports a high-speed on-chip oscillator frequency of up to 32 MHz (±2.0% accuracy at −40 to +105°C). This clock source feeds the PLL to generate higher system frequencies (e.g., 64 MHz) and enables minimum instruction execution time of 0.03125 μs. Frequency selection is controlled via option byte bits and HOCODIV register settings per datasheet Section 2.2.2.

Does the R5F11CCCGBG#W0 support background data flash rewriting while executing code from program memory?

Yes, the R5F11CCCGBG#W0 supports background operation (BGO) for data flash rewriting. Instructions can be executed from code flash memory while the 4 KB data flash is being rewritten - a feature critical for firmware-over-the-air updates and real-time parameter logging. The DTC and ELC peripherals coordinate this operation without CPU intervention, as confirmed in Section 1.1 of the datasheet.

How many differential analog input channels does the R5F11CCCGBG#W0 support via its PGA?

The R5F11CCCGBG#W0 supports four fully differential analog input channels via its programmable-gain instrumentation amplifier (PGA0–PGA3). Each channel accepts differential inputs (e.g., PGA0P/PGA0N) and allows independent gain selection from x1 to x64. This capability is explicitly documented in Section 1.1 and Figure 1.5.2 of the R01DS0274EJ0130 datasheet.

What is the purpose of the SBIAS pin on the R5F11CCCGBG#W0, and what voltage range does it provide?

The SBIAS pin on the R5F11CCCGBG#W0 provides a programmable bias voltage (0.5 V to 2.2 V) optimized for powering MEMS sensors such as accelerometers and pressure transducers. It is internally regulated and requires a 0.22 μF capacitor to AVSS per datasheet Caution 5. This eliminates external bias circuitry and improves noise immunity in sensitive analog measurements.

Can the R5F11CCCGBG#W0 operate in industrial temperature range without derating?

Yes, the R5F11CCCGBG#W0 is rated for continuous operation from −40 to +105°C (G-grade) without derating under standard conditions (VDD = 2.4–5.5 V). Electrical characteristics in this range are fully specified in Section 2 of the datasheet. Derating guidance applies only above +85°C and requires consultation with Renesas sales per Caution 3 on page 11.
