Product details
Overview
R5F11ZBADFP#30 from Renesas Electronics is a 32-pin LQFP, industrial-grade (−40°C to +85°C) RL78/G1P 16-bit microcontroller with 16 KB flash, 1.5 KB RAM, 2 KB data flash, 8-channel 12-bit A/D converter, dual 10-bit D/A outputs, and integrated low-power peripherals for sensor and general-purpose control. It operates from 2.7 V to 3.6 V and supports true low-power operation down to 0.31 μA in STOP mode with LVD active.
For engineers reviewing the R5F11ZBADFP#30 datasheet, R5F11ZBADFP#30 pinout, R5F11ZBADFP#30 application, or R5F11ZBADFP#30 equivalent, key selection considerations include its 32-pin LQFP-0.8 mm package, 8-channel analog input capability, on-chip debug support, 2.7–3.6 V supply range, and industrial temperature qualification - all critical for embedded sensor node and motor control designs requiring long battery life and robust analog integration.
Technical Context
The R5F11ZBADFP#30 implements the RL78 CPU core with four 16-bit timer channels (TAU), one watchdog timer, and an event link controller (ELC) enabling hardware-triggered peripheral coordination without CPU intervention. Its clock system combines a high-speed on-chip oscillator (selectable up to 32 MHz) with external crystal support (1–20 MHz) and a dedicated 15 kHz low-speed oscillator for ultra-low-power wake-up.
It integrates a full analog subsystem: 8-channel 12-bit A/D converter with AVREFP/AVREFM inputs, two 10-bit D/A outputs (ANO0/ANO1), and on-chip voltage detector (LVD) with four programmable thresholds (2.75–3.13 V). All I/Os are CMOS with 2 N-ch open-drain pins rated to 6 V, supporting mixed-signal interfacing in industrial environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11ZBAAFP#30 | Same package and peripherals, but consumer-grade (−40°C to +85°C, 'A' suffix) with identical electrical specs | Not qualified for industrial environments requiring extended reliability validation | Select only for cost-sensitive consumer products where industrial qualification is unnecessary |
| R5F11Z7ADNA#20 | 24-pin HWQFN-4×4 mm, 6-channel A/D, 16 KB flash, same industrial temp rating and LVD features | Lower pin count limits I/O and analog channel availability; smaller footprint suits space-constrained designs | Choose when board area is critical and 6 A/D channels suffice; not pin-compatible with R5F11ZBADFP#30 |
Compared with R5F11ZBAAFP#30, the R5F11ZBADFP#30 adds industrial qualification assurance; compared with R5F11Z7ADNA#20, it delivers 2 additional A/D channels and 2 more I/O pins in a larger LQFP package - making it optimal for sensor-rich industrial controllers needing both precision and expandability.

FAQ
What is the maximum operating frequency of the R5F11ZBADFP#30?
The R5F11ZBADFP#30 supports a maximum CPU operating frequency of 32 MHz using its high-speed on-chip oscillator. When driven by an external crystal or clock source, it operates up to 20 MHz. The minimum instruction execution time is 0.03125 μs at 32 MHz, enabling responsive real-time control in applications such as motor commutation and sensor sampling. This performance is fully supported across its −40°C to +85°C industrial temperature range.
Does the R5F11ZBADFP#30 support in-system programming and debugging?
Yes, the R5F11ZBADFP#30 includes a full on-chip debug function accessible via the TOOL0 pin (P40) and supports self-programming of both code flash and data flash memory. It uses Renesas' standard E1/E20 debug interface and allows firmware updates in the field without removing the device from the PCB. The R5F11ZBADFP#30 also reserves dedicated RAM areas (FF900H–FFC7FH) for flash library execution during reprogramming operations.
How many analog-to-digital converter channels does the R5F11ZBADFP#30 have, and what is their resolution?
The R5F11ZBADFP#30 integrates an 8-channel, 12-bit successive-approximation A/D converter with selectable resolution (8/10/12 bits) and built-in sample-and-hold. Channels ANI0 through ANI7 are mapped to P20–P27 and P10, supporting differential or single-ended measurements referenced to AVREFP/AVREFM. This configuration enables high-accuracy sensor interfacing - for example, thermistor or bridge-based strain gauge readings - without external signal conditioning circuitry.
What power-saving modes are available on the R5F11ZBADFP#30, and what are their typical current draws?
The R5F11ZBADFP#30 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with LVD enabled, it consumes just 0.31 μA (typical) at 25°C - ideal for long-duration sleep between sensor readings. HALT mode draws 320–530 μA (LS mode, 8 MHz) and retains RAM and peripheral context. SNOOZE mode allows selective peripheral operation (e.g., A/D conversion) while CPU remains halted, optimizing energy use in duty-cycled measurement systems.
Is the R5F11ZBADFP#30 pin-compatible with other RL78/G1P variants?
No, the R5F11ZBADFP#30 is not pin-compatible with 24-pin RL78/G1P variants like R5F11Z7ADNA#20 due to its 32-pin LQFP package versus their 24-pin HWQFN. Within the 32-pin family, R5F11ZBADFP#30 and R5F11ZBAAFP#30 share identical pinouts and package dimensions, differing only in industrial ('D') vs. consumer ('A') temperature qualification. Always verify mechanical and thermal constraints before substitution.
