Renesas R5F101GAANA#00

Overview

R5F101GAANA#00 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for battery-powered industrial control and sensor interface applications.

For engineers reviewing the R5F101GAANA#00 datasheet, R5F101GAANA#00 pinout, R5F101GAANA#00 application, or R5F101GAANA#00 equivalent, key selection considerations include its 48-pin HWQFN-0.5mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (A suffix), and integrated 10-bit ADC with 26 channels, RTC, and multiple serial interfaces including UART/LIN, I²C, and CSI.

Technical Context

The R5F101GAANA#00 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @ 32 MHz). It supports multiple low-power modes-HALT, STOP, and SNOOZE-with dedicated low-speed oscillator for RTC and LVD operation during deep sleep.

It integrates a 10-bit A/D converter with up to 26 input channels, internal 1.45 V reference and temperature sensor, real-time clock with calendar/alarm/correction, and dual-channel DMA controller. Serial connectivity includes up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels.

FAQ

What is the operating voltage range for the R5F101GAANA#00?

The R5F101GAANA#00 operates across a wide supply range of 1.6 V to 5.5 V, enabling direct integration with diverse power sources including single-cell Li-ion, coin cells, and standard 3.3 V/5 V rails. This flexibility simplifies power architecture in mixed-voltage systems and supports brown-out detection down to 1.6 V without external supervision circuits.

Does the R5F101GAANA#00 include on-chip data flash memory?

No, the R5F101GAANA#00 does not include on-chip data flash memory. As indicated by the "101" prefix in the part number (per Renesas RL78/G13 documentation), this variant provides only code flash (128 KB) and SRAM (12 KB), with no dedicated data flash block. For applications requiring EEPROM-like nonvolatile storage, external memory or code flash wear-leveling must be implemented.

What package type and pin count does the R5F101GAANA#00 use?

The R5F101GAANA#00 uses a 48-pin HWQFN (Heat Sink Quad Flat No-lead) package measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This compact, surface-mount package supports high-density PCB layouts and efficient heat dissipation, and is compatible with standard reflow profiles for lead-free assembly.

What is the maximum clock frequency and performance of the R5F101GAANA#00?

The R5F101GAANA#00 achieves a maximum operating frequency of 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core executes instructions in as little as 0.03125 μs at full speed using the high-accuracy on-chip oscillator (±1.0%), eliminating the need for external crystals in many timing-critical yet cost-sensitive applications.

Which serial communication interfaces are supported by the R5F101GAANA#00?

The R5F101GAANA#00 supports up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels. These interfaces can be flexibly assigned to different port pins via register configuration, allowing concurrent use in multi-protocol systems such as sensor hubs communicating with analog front-ends (SPI), displays (I²C), and vehicle networks (LIN).
