Product details
Overview
R5F101GAANA#20 from Renesas is a 16-bit RL78/G13 microcontroller with no data flash, 128 KB code flash, 12 KB RAM, and 48-pin HWQFN (7 × 7 mm, 0.5-mm pitch) package, operating from 1.6 V to 5.5 V across –40°C to +85°C industrial ambient range. It delivers 41 DMIPS at 32 MHz, integrates RTC, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and ultra-low-power modes including STOP (0.57 μA) and HALT.
For engineers reviewing the R5F101GAANA#20 datasheet, R5F101GAANA#20 pinout, R5F101GAANA#20 application, or R5F101GAANA#20 equivalent, key selection criteria include its data-flash-free configuration for cost-sensitive firmware-immutable designs, 48-pin HWQFN footprint compatibility with space-constrained industrial control PCBs, and verified support for real-time sensor aggregation with background data flash emulation via RAM-based library.
Technical Context
The R5F101GAANA#20 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports on-chip debug, self-programming with boot swap, and BGO-capable flash operations using dedicated RAM regions (start address F7F00H).
Its peripheral set includes up to 16× 16-bit timers, 1× real-time clock with calendar/alarm, 1× watchdog timer, 2–4 channel DMA, 16×16-bit multiplier/divider/MAC, and mixed-signal features: internal 1.45 V reference, temperature sensor, and LVD with 14-level interrupt/reset selection.

FAQ
What is the flash memory configuration of the R5F101GAANA#20?
The R5F101GAANA#20 contains 128 KB of code flash memory and no data flash memory. This configuration is optimized for applications where firmware is immutable after programming, eliminating the need for runtime data storage and reducing system-level complexity. The absence of data flash also lowers unit cost and simplifies flash management routines in the R5F101GAANA#20 firmware design.
Does the R5F101GAANA#20 support real-time clock functionality?
Yes, the R5F101GAANA#20 integrates a full-featured real-time clock (RTC) with calendar support for 99 years, alarm interrupt capability, and hardware clock correction. It operates independently in STOP mode using the 32.768 kHz subsystem clock, enabling accurate timekeeping without external RTC ICs - a key feature confirmed in the R5F101GAANA#20 datasheet section 1.1 Features.
What package type and dimensions does the R5F101GAANA#20 use?
The R5F101GAANA#20 uses a 48-pin HWQFN package measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This package is designated in the Renesas ordering code as "ANA" and corresponds to part number PWQN0048KB-A per the official packaging specification. Its compact footprint and thermal performance make the R5F101GAANA#20 suitable for space-constrained industrial PCBs.
Can the R5F101GAANA#20 operate across extended temperature ranges?
The R5F101GAANA#20 is rated for industrial operation from –40°C to +85°C, as indicated by the "A" suffix in its ordering code (R5F101GAANA#20). It does not support the –40°C to +105°C range (designated by "G" suffix variants). This temperature grade ensures reliable performance in unheated factory environments and outdoor metering enclosures where ambient extremes remain within the R5F101GAANA#20 specification.
How many analog input channels does the R5F101GAANA#20 ADC support?
The R5F101GAANA#20 features a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), as specified in the RL78/G13 datasheet section 1.1. These channels are mapped across multiple I/O ports and support differential measurement modes when used with AVREFP/AVREFM pins - a capability directly applicable to precision sensor signal conditioning in the R5F101GAANA#20.
