Product details
Overview
R5F101GKANA#U0 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 256 KB flash, 8 KB data flash, and 20 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101GKANA#U0 datasheet, R5F101GKANA#U0 pinout, R5F101GKANA#U0 application, or R5F101GKANA#U0 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and support for background data flash rewriting via BGO.
Technical Context

FAQ
What is the flash memory configuration of the R5F101GKANA#U0?
The R5F101GKANA#U0 contains 256 KB of code flash memory and no on-chip data flash memory - consistent with the R5F101x series designation indicating data flash omission. Its 20 KB RAM supports real-time data buffering and stack operations, while flash security features prohibit block erase/write to protect firmware IP.
Does the R5F101GKANA#U0 support real-time clock functionality?
Yes, the R5F101GKANA#U0 integrates a full-featured real-time clock (RTC) with calendar support for 99 years, alarm generation, and automatic clock correction - all operational in STOP mode with only 0.57 μA current draw when paired with the on-chip LVD circuit.
What package type and dimensions does the R5F101GKANA#U0 use?
The R5F101GKANA#U0 uses a 48-pin HWQFN package (PWQN0048KB-A) measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This leadless package delivers superior thermal performance and board-space efficiency compared to equivalent LQFP alternatives.
How does the R5F101GKANA#U0 achieve ultra-low power consumption?
The R5F101GKANA#U0 achieves 0.57 μA STOP-mode current via dedicated low-leakage circuit blocks, selective clock gating, and retention of only RTC and LVD logic during deep sleep - validated across -40°C to +85°C. Its 66 μA/MHz active-mode efficiency stems from adaptive voltage scaling and optimized peripheral clock trees.
Which serial communication interfaces are available on the R5F101GKANA#U0?
The R5F101GKANA#U0 provides three concurrent serial interface types: up to 10-channel I²C/Simplified I²C, 2–4-channel UART/LIN, and 2–8-channel CSI (Renesas' SPI-compatible interface). All share flexible pin mapping and support multi-drop and master/slave configurations without external level shifters.
