Product details
Overview
R5F11BBCGFP#10 from Renesas Electronics is a 32-pin LFQFP (7 × 7 mm, 0.8 mm pitch), industrial-grade RL78/G1F 16-bit microcontroller with 32 KB flash, 4 KB data flash, 5.5 KB RAM, and true low-power operation down to 66 μA/MHz. It integrates an 8/10-bit ADC (13 channels), dual 8-bit DACs, two comparators, one PGA, nine 16-bit timers (including RTC and PWMOPA), three UART/LIN channels, three I²C interfaces, and three CSI/SPI channels - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F11BBCGFP#10 datasheet, R5F11BBCGFP#10 pinout, R5F11BBCGFP#10 application, or R5F11BBCGFP#10 equivalent, key selection criteria include its −40 to +105°C industrial temperature rating, 1.6–5.5 V wide supply range, on-chip debug support, self-programming with boot swap, and background data flash rewriting capability for firmware updates without halting execution.
Technical Context
The RL78/G1F core implements a CISC architecture with 3-stage pipeline and supports instruction execution times from 0.03125 μs (32 MHz high-speed on-chip oscillator) to 30.5 μs (32.768 kHz subsystem clock). It features a dedicated low-speed on-chip oscillator (15 kHz TYP.) for watchdog and RTC operation independent of main clock domains.
Power management includes HALT, STOP, and SNOOZE modes, plus an on-chip voltage detector with 14 selectable LVD levels and POR circuit (1.51 ±0.04 V reset threshold). Peripheral integration centers on Event Link Controller (22 event inputs) and Data Transfer Controller (32 activation sources) enabling autonomous peripheral coordination without CPU intervention.

The R5F11BBCGFP#10 supports up to 32 MHz CPU operation using the high-speed on-chip oscillator, with guaranteed operation from 1.6 V to 5.5 V. At 32 MHz, minimum VDD is 2.7 V per electrical specifications; below 2.7 V, max frequency scales down to 16 MHz (2.4–2.7 V) or 8 MHz (1.8–2.4 V) to maintain timing integrity and noise immunity.
Does the R5F11BBCGFP#10 support LIN bus communication, and how is it implemented?
Yes, the R5F11BBCGFP#10 supports LIN 2.2 communication via UART0 channel with dedicated LINSEL pin functionality. The hardware UART includes automatic sync-break detection, checksum calculation, and identifier filtering - enabling full LIN slave node implementation without external transceiver logic beyond the physical layer driver.
How many analog input channels does the R5F11BBCGFP#10 provide, and what reference options are available?
The R5F11BBCGFP#10 provides 13 analog input channels (ANI0–ANI7, ANI16–ANI20) with 8/10-bit resolution. Reference options include external AVREFP/AVREFM pins, internal 1.45 V bandgap reference, or VDD itself - selectable per channel via ADC control registers to optimize SNR for different sensor types.
Can the R5F11BBCGFP#10 perform data flash writes while executing code from main flash memory?
Yes, the R5F11BBCGFP#10 supports Background Operation (BGO) for data flash, allowing program execution from code flash memory during data flash erase/write sequences. This enables seamless firmware parameter updates or logging without halting real-time control tasks - critical for uninterrupted industrial process monitoring.
What packaging and lead finish does the R5F11BBCGFP#10 use, and is it RoHS compliant?
The R5F11BBCGFP#10 uses a 32-pin plastic LQFP package (7 × 7 mm, 0.8 mm pitch) with matte tin lead finish. It is fully RoHS compliant and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), requiring bake condition prior to reflow if exposed beyond floor life.
