FAQ

What is the maximum operating frequency and DMIPS rating of the R5F100GLANA#U0?

The R5F100GLANA#U0 operates at up to 32 MHz with a peak performance of 41 DMIPS. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator (±1.0% accuracy across VDD = 1.8–5.5 V and TA = −20 to +85°C). The R5F100GLANA#U0 maintains this performance while consuming only 66 μA per MHz in active mode, making it suitable for compute-constrained yet power-sensitive applications like portable instrumentation.

Does the R5F100GLANA#U0 support LIN bus communication natively?

Yes, the R5F100GLANA#U0 supports LIN bus communication through its UART peripheral, which includes dedicated LIN-mode features such as automatic break detection, sync field generation, and checksum calculation. These hardware-accelerated functions offload timing-critical tasks from firmware, ensuring reliable frame transmission and reception without CPU intervention - a key advantage in automotive body electronics and industrial sub-networks using R5F100GLANA#U0.

What is the purpose and capacity of the data flash memory in the R5F100GLANA#U0?

The R5F100GLANA#U0 includes 8 KB of dedicated data flash memory designed for nonvolatile parameter storage, calibration data, and event logs. It supports background operation (BGO), allowing program execution from main flash while rewriting data flash, and guarantees 1,000,000 write cycles at VDD = 1.8–5.5 V. This capability enables robust field updates and runtime configuration persistence - critical for applications like smart meters and industrial controllers relying on R5F100GLANA#U0.

How does the R5F100GLANA#U0 achieve ultra-low power consumption in STOP mode?

The R5F100GLANA#U0 achieves 0.57 μA in STOP mode by powering down the CPU, flash, and most peripherals while retaining operation of the real-time clock (RTC), low-voltage detector (LVD), and RAM retention. This state is entered via software command and exited by RTC alarm, LVD interrupt, or external pin wakeup - enabling decade-long battery life in applications such as utility meters and wireless sensors using R5F100GLANA#U0.

Is the R5F100GLANA#U0 pin-compatible with other RL78/G13 variants in the same package?

Yes, the R5F100GLANA#U0 is pin-compatible with all 48-pin HWQFN variants of the RL78/G13 family (e.g., R5F100FLANA#U0, R5F100JLANA#U0), sharing identical pin functions, electrical characteristics, and footprint. This allows scalable design reuse - for example, upgrading from 96 KB to 128 KB flash without PCB revision - provided peripheral usage aligns with the specific variant's feature set and memory map defined in the R5F100GLANA#U0 datasheet.
