Product details
Overview
R5F101GJAFB#V0 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 192 KB flash, 8 KB data flash, and 16 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and integrated real-time clock - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101GJAFB#V0 datasheet, R5F101GJAFB#V0 pinout, R5F101GJAFB#V0 application, or R5F101GJAFB#V0 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, absence of on-chip data flash (R5F101x series), -40°C to +105°C industrial temperature grade (G suffix), and support for SNOOZE mode DMA transfers during low-power operation.
Technical Context
The R5F101GJAFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 16× 16-bit timers, 3–10-channel I²C/Simplified I²C, 2–4 UART/LIN interfaces, 2–8 CSI (SPI-compatible) channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all configurable under single-supply 1.6–5.5 V operation with on-chip POR and 14-level LVD.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101GJAFB#V0?
The R5F101GJAFB#V0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency and is validated under typical industrial conditions (VDD = 3.3 V, TA = 25°C). The R5F101GJAFB#V0 achieves this without external clock multiplication, relying solely on its high-accuracy on-chip oscillator (±1.0% over -20°C to +85°C).
Does the R5F101GJAFB#V0 include on-chip data flash memory?
No, the R5F101GJAFB#V0 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number per Renesas documentation, it belongs to the data-flash-less variant of the RL78/G13 family. The R5F101GJAFB#V0 provides 192 KB of code flash and 16 KB of RAM, but persistent data storage requires external EEPROM or FRAM if needed in the R5F101GJAFB#V0 design.
What is the operating temperature range specified for the R5F101GJAFB#V0?
The R5F101GJAFB#V0 is rated for operation from -40°C to +105°C, as confirmed by the "G" suffix in its ordering code. This industrial-grade temperature specification aligns with Renesas' classification for high-reliability applications such as motor drives, power supplies, and automotive cabin electronics - and is verified in the official R01DS0131EJ0380 datasheet revision 3.80.
Which package type and pin count does the R5F101GJAFB#V0 use?
The R5F101GJAFB#V0 uses a 48-pin LFQFP package with 0.5 mm pitch, as designated by the "FB" suffix and "#V0" tray packaging code. Its physical dimensions are 7 mm × 7 mm, and it complies with JEDEC standard MS-026. This package is distinct from HWQFN or LQFP variants in the same family and is fully supported by Renesas' reference schematics and layout guidelines for the R5F101GJAFB#V0.
How many analog input channels and what ADC resolution does the R5F101GJAFB#V0 support?
The R5F101GJAFB#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. In its 48-pin LFQFP configuration, up to 16 of these channels (ANI0–ANI15) are accessible on dedicated pins. The ADC operates across the full 1.6–5.5 V supply range and includes an internal 1.45 V reference and factory-calibrated temperature sensor - both usable without external components in the R5F101GJAFB#V0 design.
