FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100GLAFB#30?
The R5F100GLAFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency and is validated under standard test conditions per Renesas documentation. The R5F100GLAFB#30 maintains this performance across its full 1.6–5.5 V supply range and −40°C to +105°C temperature grade.
Does the R5F100GLAFB#30 include an integrated temperature sensor, and how is it accessed?
Yes, the R5F100GLAFB#30 includes a factory-calibrated on-chip temperature sensor accessible only in HS (high-speed main) mode. It connects to the 10-bit ADC as ANI channel 25 and uses the internal 1.45 V reference voltage. Calibration data is stored in ROM, enabling accurate ambient temperature measurement without external components. This feature is confirmed in the R01DS0131EJ0380 datasheet Section 1.1 Features.
What low-power modes does the R5F100GLAFB#30 support, and what is the lowest achievable current consumption?
The R5F100GLAFB#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current consumption at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables multi-year operation on primary batteries in metering and sensor applications. All modes retain RAM content and allow wake-up via interrupts or reset events.
Is the R5F100GLAFB#30 pin-compatible with other RL78/G13 variants in the same 48-pin LFQFP package?
Yes, the R5F100GLAFB#30 shares identical pinout and electrical characteristics with all other RL78/G13 48-pin LFQFP variants (e.g., R5F100GKAFB#30, R5F100GHAFB#30), regardless of flash size or data flash configuration. Pin assignments for power, I/O, peripherals, and clocks are fully consistent across the family, enabling hardware reuse when migrating between memory variants.
What development tools and debug interfaces are supported for the R5F100GLAFB#30?
The R5F100GLAFB#30 supports Renesas' E2 emulator Lite and E2 emulator via the on-chip debug interface (OCDS), compatible with CS+ IDE and e² studio. It requires no external debug header - SWD/JTAG signals are routed through dedicated pins (e.g., RES#, P00–P03). Flash programming and real-time debugging are fully supported, including data flash BGO verification and low-power mode stepping.
