FAQ
What is the maximum operating frequency and core performance of the R5F100GEGFB#10?
The R5F100GEGFB#10 operates at up to 32 MHz with the RL78 16-bit CISC core, delivering 41 DMIPS. Its minimum instruction execution time is 0.03125 μs in high-speed mode (32 MHz with on-chip oscillator), and it supports ultra-low-speed operation down to 32.768 kHz for RTC and low-power sensing tasks - all within a single chip without external clock sources.
Does the R5F100GEGFB#10 include on-chip debug capability and what interfaces does it support?
Yes, the R5F100GEGFB#10 includes full on-chip debug functionality accessible via the single-wire debug (SWD) interface using pins P11 (TOOLRxD) and P10 (TOOLTxD). It supports flash programming, real-time variable monitoring, and breakpoint debugging through Renesas E2 studio and CS+ IDEs - no external debugger hardware is required for development or field firmware updates.
What are the flash memory configuration and endurance specifications for the R5F100GEGFB#10?
The R5F100GEGFB#10 integrates 128 KB of code flash memory and 8 KB of data flash memory. Code flash is organized in 1 KB blocks with programmable erase/write protection. Data flash supports background operation (BGO), 1,000,000 write/erase cycles (typical), and rewrites across the full VDD range (1.8–5.5 V). Both flash types support self-programming with boot swap and flash shield window features for secure firmware updates.
How does the R5F100GEGFB#10 handle power management and brown-out conditions?
The R5F100GEGFB#10 incorporates an on-chip power-on-reset (POR) circuit and a 14-level voltage detector (LVD) that can be configured to generate either interrupt or reset events. The LVD operates across the full 1.6–5.5 V supply range and supports independent monitoring of VDD or internal regulators - enabling robust brown-out detection and graceful shutdown without external supervisor ICs.
Is the R5F100GEGFB#10 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100GEGFB#10 is fully pin-compatible with all 48-pin LFQFP variants of the RL78/G13 family, including R5F100GGGFB#10, R5F100GKAFB#10, and R5F101GEGFB#10.
