FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100CGGLA#U0?
The R5F100CGGLA#U0 operates at up to 32 MHz using its high-speed on-chip oscillator and achieves 41 DMIPS (Dhrystone MIPS) at that frequency. This performance level is confirmed in the official Renesas datasheet R01DS0131EJ0380 Rev.3.80, page 1, and reflects optimized CISC execution with 3-stage pipeline efficiency. The R5F100CGGLA#U0 maintains this rating across its full industrial temperature range (-40°C to +105°C).
Does the R5F100CGGLA#U0 support LIN bus communication, and how is it implemented?
Yes, the R5F100CGGLA#U0 supports LIN bus communication through its UART peripheral, which includes dedicated LIN-mode functionality per the RL78/G13 datasheet. The UART hardware handles LIN break detection, sync field generation, and checksum calculation - eliminating software overhead. This capability is validated in Section 1.1 "Features" and Section 13 "Serial Interface" of R01DS0131EJ0380, confirming LIN compliance for automotive body electronics applications using the R5F100CGGLA#U0.
What are the data flash endurance and rewrite voltage specifications for the R5F100CGGLA#U0?
The R5F100CGGLA#U0 includes 4 KB of data flash rated for 1,000,000 write/erase cycles (typical) with rewrite operation supported across the full supply range of 1.8 V to 5.5 V. This specification is explicitly stated in the "Data Flash Memory" subsection of Section 1.1 Features in R01DS0131EJ0380 Rev.3.80. The R5F100CGGLA#U0 also supports background operation (BGO), enabling concurrent code execution and data flash rewriting - a key advantage for field-upgradable firmware designs.
Is the R5F100CGGLA#U0 pin-compatible with other RL78/G13 variants in the same package?
The R5F100CGGLA#U0 shares identical pinout and electrical characteristics with all other 36-pin WFLGA RL78/G13 devices, including R5F100AGGLA#U0, R5F100DGGLA#U0, and R5F100EGGLA#U0, as confirmed by the "Pin Configuration (Top View)" diagrams in Section 1.3 of R01DS0131EJ0380. This allows direct substitution within the same memory/feature tier - though firmware must be verified for feature enablement (e.g., ADC channel count, timer availability) before drop-in replacement of the R5F100CGGLA#U0.
What debug interface does the R5F100CGGLA#U0 provide, and is external hardware required?
The R5F100CGGLA#U0 integrates an on-chip debug system (OCDS) accessible via a 2-pin SWD (Serial Wire Debug) interface - requiring only SWDIO and SWCLK connections plus power and ground. No external JTAG adapter is needed. This is documented in Section 1.1 "Features" and Section 23 "On-Chip Debug Function" of R01DS0131EJ0380. The R5F100CGGLA#U0 supports full breakpoint, watchpoint, and real-time trace capabilities, enabling efficient development and validation without adding debug headers to production PCBs.
