FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100LJGFB#X0?
The R5F100LJGFB#X0 operates at up to 32 MHz using its high-speed on-chip oscillator and delivers 41 DMIPS (Dhrystone MIPS) at that frequency. Its minimum instruction execution time is 0.03125 μs in HS mode, confirmed in the RL78/G13 datasheet Rev.3.80. This performance level supports real-time control loops and protocol stacks without external acceleration.
Does the R5F100LJGFB#X0 include an integrated real-time clock (RTC) with calendar functionality?
Yes, the R5F100LJGFB#X0 includes a fully featured RTC with calendar support for years, months, days, hours, minutes, and seconds (99-year range), alarm interrupt capability, and automatic clock correction. This RTC operates independently in STOP and HALT modes using the 32.768 kHz subsystem clock, eliminating the need for external RTC components in time-stamped applications.
How much data flash memory does the R5F100LJGFB#X0 provide, and what is its endurance specification?
The R5F100LJGFB#X0 provides 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) across the full VDD range of 1.8 V to 5.5 V. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash - essential for reliable runtime parameter storage in the R5F100LJGFB#X0.
What is the operating temperature range specified for the R5F100LJGFB#X0, and how is it indicated in the part number?
The R5F100LJGFB#X0 is rated for -40°C to +105°C operation, designated by the "G" suffix in the part number (R5F100LJGFB#X0), indicating industrial-grade qualification. This extended range is validated per Renesas' reliability testing standards and supports deployment in harsh environments such as factory floors, outdoor energy infrastructure, and automotive under-hood auxiliary systems.
Which communication interfaces are supported by the R5F100LJGFB#X0, and how many instances of each are available?
The R5F100LJGFB#X0 supports up to 3 I²C/Simplified I²C channels, 2 UART/LIN interfaces (with LIN 2.2 compliance), and 2 CSI (SPI-compatible) channels. These are implemented in hardware with dedicated registers and DMA support, enabling concurrent operation - for example, one UART for debug, one for LIN bus communication, and I²C for sensor interfacing - all within the R5F100LJGFB#X0's unified peripheral architecture.
