Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GLANA#20 → R5F101GLANA#60 | Same die, different packaging: #60 = embossed tape (reel) vs. #20 = tray | Identical electrical and functional behavior; differs only in logistics and assembly handling | Select #20 for prototyping and small-batch SMT; #60 for high-volume automated placement |
| R5F101GLANA#20 → R5F101GLAFA#V0 | LQFP-48 package (7 × 7 mm, 0.5 mm pitch) vs. HWQFN-48; same memory/peripherals | LQFP offers easier hand-soldering and in-circuit debugging; HWQFN provides smaller footprint and better thermal performance | Choose HWQFN (#20) for space-constrained PCBs; LQFP (#V0) for development and test fixtures |

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101GLANA#20?
The R5F101GLANA#20 operates at up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over –40°C to +105°C), delivering 41 DMIPS. This performance level supports real-time control tasks such as PID loops, sensor fusion, and protocol stack processing while maintaining ultra-low power consumption - verified in Renesas' R01DS0131EJ0380 datasheet Section 1.1.
Does the R5F101GLANA#20 include an integrated real-time clock with calendar functionality?
Yes, the R5F101GLANA#20 integrates a full-featured real-time clock (RTC) with 99-year calendar support, alarm interrupt, and automatic clock correction - all operational in STOP mode with only 0.57 μA current draw. This eliminates the need for external RTC ICs in time-stamped logging or scheduled wake-up applications.
How much flash and RAM memory does the R5F101GLANA#20 provide, and what are their usage models?
The R5F101GLANA#20 provides 128 KB of code flash memory (1 KB erase blocks, self-programmable with boot swap), 8 KB of data flash memory (1 million write cycles, background operation enabled), and 12 KB of on-chip RAM. Code flash stores firmware; data flash retains configuration and logs during power loss; RAM hosts runtime variables and stack - confirmed in RL78/G13 datasheet Table 1-1 and Section 1.1.
What communication interfaces are available on the R5F101GLANA#20, and which support LIN bus?
The R5F101GLANA#20 includes 2 UART channels with native LIN 2.2 physical layer support, 3 I²C interfaces, and 2 CSI (SPI-compatible) channels. UART0 and UART1 both support LIN break detection, sync, and checksum generation - enabling direct connection to automotive or industrial LIN networks without transceiver translation.
What low-power modes does the R5F101GLANA#20 support, and what is its lowest active current consumption?
The R5F101GLANA#20 supports HALT, STOP, and SNOOZE modes. Its lowest active-mode current is 66 μA per MHz at 32 MHz (2.112 mA total), and STOP mode draws just 0.57 μA when only RTC and LVD remain active - making it suitable for battery-powered edge nodes requiring multi-year operation on primary cells.
