Overview
R5F104GLANA#W0 from Renesas is a 48-pin HWQFN-packaged RL78/G14 16-bit microcontroller with 512 KB flash, 48 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +105°C (industrial G-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (20 ch), RTC, and on-chip oscillators for embedded control in battery-powered industrial sensors and motor drives.
For engineers reviewing the R5F104GLANA#W0 datasheet, R5F104GLANA#W0 pinout, R5F104GLANA#W0 application, or R5F104GLANA#W0 equivalent, key selection criteria include its 48-pin HWQFN (7×7 mm, 0.5 mm pitch) package, industrial temperature rating (−40 to +105°C), integrated data flash with 1M rewrite cycles, and support for SNOOZE mode for low-power sensor wake-up.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104GLANA#W0?
The R5F104GLANA#W0 operates at up to 32 MHz, delivering 44 DMIPS of processing performance. This is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set. The high-speed on-chip oscillator supports ±1.0% accuracy across −20 to +85°C, eliminating the need for an external crystal in many applications. At 32 MHz, the minimum instruction execution time is 0.03125 μs, enabling tight real-time control loops in motor or power conversion systems.
Does the R5F104GLANA#W0 support in-system programming and secure firmware updates?
Yes, the R5F104GLANA#W0 supports full in-system programming via its on-chip debug interface and includes multiple security features for firmware protection. It implements flash shield window functionality to restrict read/write access to designated memory regions, prohibits block erase and rewriting for protected areas, and supports boot swap functionality for fail-safe firmware updates. These capabilities are enabled through the integrated flash self-programming library and require no external programming hardware beyond standard SWD/JTAG tools.
What are the power consumption modes supported by the R5F104GLANA#W0, and what are their typical current draws?
The R5F104GLANA#W0 supports HALT, STOP, and SNOOZE low-power modes. In active operation at 32 MHz, it consumes 66 μA/MHz. In STOP mode with only RTC and LVD active, it draws just 0.60 μA - ideal for long-duration sleep in battery-powered applications. SNOOZE mode allows selected peripherals (e.g., ADC, UART) to operate autonomously while the CPU remains halted, enabling event-driven wake-up with minimal latency and power overhead. All modes retain RAM content and register states.
How many serial communication interfaces does the R5F104GLANA#W0 integrate, and what protocols do they support?
The R5F104GLANA#W0 integrates up to four UART channels (with LIN-bus support), ten I²C/simplified I²C channels, and eight CSI (SPI-compatible) channels. UART0 is accessible on P50/P51 for debug and host communication; additional UARTs (e.g., UART1 on P00/P01) support multi-protocol connectivity. I²C channels support standard/fast-mode speeds and can be configured as master or slave. CSI modules provide full-duplex synchronous serial communication compatible with SPI peripherals, with configurable clock polarity and phase.
Is the R5F104GLANA#W0 qualified for industrial temperature operation, and what packaging option does it use?
Yes, the R5F104GLANA#W0 is rated for industrial operation from −40 to +105°C (G-grade), making it suitable for demanding environments such as factory automation, power supplies, and outdoor sensor enclosures. It is packaged in a 48-pin HWQFN (7 × 7 mm, 0.5 mm pitch) with embossed tape (#W0) packaging, and the exposed die pad must be connected to VSS for optimal thermal dissipation and EMI suppression. This package offers high I/O density and excellent thermal performance in compact designs.
