Product details
Overview
R5F11B7EGNA#W0 from Renesas Electronics is a 24-pin, 64 KB Flash, 5.5 KB RAM RL78/G1F 16-bit microcontroller operating at up to 32 MHz with true low-power operation (66 μA/MHz active, 0.57 μA in RTC+LVD mode), 1.6–5.5 V supply, and integrated 8/10-bit ADC (8 channels), 8-bit DAC (1 channel), 2 comparators, and programmable gain amplifier - deployed in battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F11B7EGNA#W0 datasheet, R5F11B7EGNA#W0 pinout, R5F11B7EGNA#W0 application, or R5F11B7EGNA#W0 equivalent, key selection criteria include its HWQFN-24 (4×4 mm, 0.5 mm pitch) package, industrial-grade −40°C to +105°C operation, 64 KB code flash with self-programming and boot swap, and dual-clock domain support (high-speed on-chip oscillator ±1.0% accuracy and 32.768 kHz subsystem clock).
Technical Context
The R5F11B7EGNA#W0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a dedicated low-speed on-chip oscillator for watchdog timer operation and supports HALT, STOP, and SNOOZE low-power modes with real-time clock calendar functionality (99-year range, alarm, correction).
Peripheral integration includes a Data Transfer Controller (DTC) with 30 activation sources, Event Link Controller (ELC) supporting 22 event signals linked to peripherals, and serial interfaces: 1 CSI (SPI-compatible), 1 UART/LIN, and 1 simplified I²C - all configurable via Peripheral I/O Redirection Registers (PIOR0–PIOR3) for flexible pin assignment.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11B7CGNA#W0 | 32 KB code flash (vs. 64 KB), identical pinout, package, and peripheral set; same 24-pin HWQFN-24 footprint and industrial temp rating. | Suitable for cost-sensitive designs with firmware under 32 KB; retains full compatibility for memory-constrained sensor nodes. | Select when application firmware fits within 32 KB and BOM cost reduction is prioritized over future firmware headroom. |
| R5F11BBEGNA#W0 | 32-pin HWQFN-32 package; adds 8 more GPIO, 2 additional ADC channels (13 total), and second UART channel - no pin compatibility. | Required for designs needing expanded I/O, dual UART (e.g., one for debug, one for fieldbus), or higher-resolution sensor fusion. | Choose when board redesign is acceptable and additional analog/digital resources justify larger footprint and higher pin count. |
Compared with R5F11B7CGNA#W0, the R5F11B7EGNA#W0 provides double the code flash for complex protocol stacks or OTA update partitions, while R5F11BBEGNA#W0 trades pin compatibility for significantly expanded peripheral count and I/O - making it suitable only when hardware revision is planned.

The R5F11B7EGNA#W0 operates at up to 32 MHz using its high-speed on-chip oscillator. At this frequency and VDD = 3.3 V, typical active current is 66 μA/MHz - resulting in approximately 2.1 mA total supply current. This value scales linearly with clock speed, enabling precise power budgeting for variable-workload applications.
Does the R5F11B7EGNA#W0 support in-system programming and secure firmware updates?
Yes, the R5F11B7EGNA#W0 supports full in-system programming via its on-chip debug interface and includes flash shield window functionality to restrict read/write access to designated memory regions. Self-programming with boot swap allows atomic firmware updates without runtime interruption - critical for field-deployed R5F11B7EGNA#W0 units.
What analog reference options are available for the ADC in the R5F11B7EGNA#W0?
The R5F11B7EGNA#W0 ADC supports three reference configurations: external VDD, external AVREFP/AVREFM differential pair, or internal 1.45 V reference. The internal reference is factory-trimmed and stable across temperature, enabling accurate single-supply measurements without external components - a key feature of the R5F11B7EGNA#W0 analog subsystem.
How many independent timer output channels does the R5F11B7EGNA#W0 provide, and what are their capabilities?
The R5F11B7EGNA#W0 integrates nine 16-bit timer channels across TAU (4), RJ (1), RD (2), RG (1), and RX (1), delivering 13 total timer output signals and 8 PWM outputs. Timer RD channels support PWMOPA for complementary PWM generation - essential for motor control and power conversion applications using the R5F11B7EGNA#W0.
Is the R5F11B7EGNA#W0 qualified for industrial temperature operation, and what are the voltage limits at that range?
Yes, the R5F11B7EGNA#W0 is rated for industrial operation from −40°C to +105°C (G-grade). At this extended temperature range, the valid supply voltage is 2.4 V to 5.5 V - a narrower lower bound than the consumer-grade A-version (1.6 V minimum) - ensuring reliable operation in harsh thermal environments for the R5F11B7EGNA#W0.
