FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100LGABG#U0?
The R5F100LGABG#U0 achieves a maximum operating frequency of 32 MHz using its high-accuracy on-chip oscillator (±1.0% over VDD = 1.8–5.5 V, TA = –20 to +85°C), delivering 41 DMIPS. This performance is sustained across its full industrial temperature range (–40°C to +105°C) with appropriate derating per datasheet specifications.
Does the R5F100LGABG#U0 support hardware-based LIN bus communication?
Yes, the R5F100LGABG#U0 supports LIN bus communication through its UART peripheral, which includes LIN-break detection, sync-field processing, and checksum generation/validation in hardware. This enables compliant LIN 2.2A node implementation without software overhead, verified in Renesas Application Note R01AN3223.
How is the 8 KB data flash organized and what is its endurance specification?
The R5F100LGABG#U0's 8 KB data flash is organized as eight 1 KB blocks and rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing CPU code execution from program memory during data flash writes - critical for real-time logging and parameter updates.
What are the supported low-power modes and their typical current consumption?
The R5F100LGABG#U0 supports HALT (1.2 μA), STOP (0.57 μA with RTC + LVD active), and SNOOZE modes. In STOP mode with only RTC and LVD enabled, it draws just 0.57 μA at VDD = 3.0 V and TA = 25°C - enabling multi-year operation on primary lithium batteries in remote sensor nodes.
Is the R5F100LGABG#U0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 64-pin VFBGA package (BG suffix) share identical pinouts and electrical characteristics. The R5F100LGABG#U0 is pin-compatible with variants like R5F100LCA BG#U0 (16 KB flash) and R5F100LLABG#U0 (512 KB flash), enabling scalable memory upgrades without PCB redesign.
