Product details
Overview
R5F11BBCGNA#20 from Renesas is a 32-pin HWQFN-packaged RL78/G1F 16-bit microcontroller with 32 KB flash, 4 KB data flash, 5.5 KB RAM, 1.6–5.5 V operation, −40 to +105°C industrial temperature range, and ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 13-channel 8/10-bit ADC, dual 8-bit DAC, two comparators, PGA, UART/LIN, I²C, CSI, IrDA, and nine 16-bit timers - deployed in battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F11BBCGNA#20 datasheet, R5F11BBCGNA#20 pinout, R5F11BBCGNA#20 application, or R5F11BBCGNA#20 equivalent, key selection criteria include verified 32-pin HWQFN (5 × 5 mm, 0.5 mm pitch) package compatibility, confirmed 32 KB flash + 4 KB data flash partitioning, validated 13-channel analog input support, industrial-grade LVD threshold staging (8 levels), and functional equivalence within RL78/G1F family variants for migration paths.
Technical Context
The R5F11BBCGNA#20 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz high-speed on-chip oscillator to 30.5 μs @ 32.768 kHz subsystem clock). It supports multiply/divide/MAC instructions and 1 MB address space across four register banks.
Its peripheral set includes a Data Transfer Controller (DTC) with 32 activation sources, Event Link Controller (ELC) supporting 22 event signals linked to peripherals, and programmable I/O redirection via PIOR0–PIOR3 registers - enabling flexible signal routing without hardware redesign.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11BBEGNA#20 | 64 KB code flash, same 32-pin HWQFN package, identical peripherals and pinout | Required when firmware exceeds 32 KB or future-proofing for feature expansion is needed | Select for larger code base or anticipated firmware growth; no PCB change required |
| R5F11BBCGFP#10 | Same 32 KB flash, but 32-pin LQFP (7 × 7 mm, 0.8 mm pitch) package with different thermal and mechanical characteristics | Suitable for legacy LQFP-based designs or where hand-soldering or thermal mass requirements differ | Choose for compatibility with existing LQFP layouts or enhanced thermal dissipation needs |
Compared with R5F11BBCGNA#20, the R5F11BBEGNA#20 provides double flash capacity without altering pinout or power/performance envelope, while the R5F11BBCGFP#10 retains identical functionality but shifts to a larger, more manufacturable LQFP footprint - making the former ideal for scalability and the latter for layout continuity.

FAQ
What is the operating temperature range certified for the R5F11BBCGNA#20?
The R5F11BBCGNA#20 is rated for industrial operation from −40 to +105°C, as indicated by the 'G' suffix in its part number. This rating applies across its full electrical specification range including flash programming, ADC accuracy, and LVD threshold stability - validated per Renesas' R01DS0246EJ0130 datasheet Section 1.1 and Table 1-1.
How many analog input channels does the R5F11BBCGNA#20 support, and what ADC resolution is available?
The R5F11BBCGNA#20 supports 13 analog input channels (ANI0–ANI7, ANI16–ANI20) with an 8/10-bit successive approximation ADC. Resolution is software-selectable per conversion, and the module includes internal 1.45 V reference and integrated temperature sensor - all confirmed in Section 1.1 and Table 1-2 of the RL78/G1F datasheet.
Does the R5F11BBCGNA#20 include hardware support for LIN bus communication?
Yes, the R5F11BBCGNA#20 includes dedicated LIN-bus support within its UART0 peripheral, as explicitly stated in Section 1.1 ("UART/UART (LIN-bus supported): 3 channels") and verified in the functional outline (Section 1.6). UART0 can operate in LIN master or slave mode with automatic sync-break detection and checksum handling.
What is the maximum CPU clock frequency achievable with the R5F11BBCGNA#20, and how is it generated?
The R5F11BBCGNA#20 achieves a maximum CPU clock of 32 MHz using its high-speed on-chip oscillator (fIH), which is factory-trimmed to ±1.0% accuracy across 1.8–5.5 V and −20 to +85°C. External crystal (X1/X2) or EXCLK input supports up to 20 MHz main system clock - both options detailed in Sections 1.1 and 1.6 of the datasheet.
Can the R5F11BBCGNA#20 perform flash memory writes while executing code from flash?
Yes, the R5F11BBCGNA#20 supports background operation (BGO) for data flash writes: code execution continues from program memory during data flash rewriting. This capability is documented in Section 1.1 ("Background operation (BGO)") and confirmed in Table 1-2, enabling seamless firmware updates and data logging without CPU suspension.
