FAQ
What is the maximum operating frequency and performance of the R5F101GLAFB#10?
The R5F101GLAFB#10 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. Its RL78 CPU core features a 3-stage pipeline and supports variable instruction execution time - from 0.03125 μs in high-speed mode to 30.5 μs in ultra-low-speed 32.768 kHz mode - making R5F101GLAFB#10 suitable for both responsive real-time tasks and ultra-low-power periodic wake-ups.
Does the R5F101GLAFB#10 include data flash memory?
No, the R5F101GLAFB#10 does not include data flash memory. As indicated by the "101" in its part number (per Renesas RL78/G13 naming convention), this variant provides 128 KB of code flash and 12 KB of RAM but omits the dedicated data flash block. For applications requiring nonvolatile parameter storage with background rewriting, consider the pin-compatible R5F100GLAFB#10, which includes 8 KB of data flash.
What industrial temperature range does the R5F101GLAFB#10 support?
The R5F101GLAFB#10 is rated for operation from −40°C to +105°C, meeting Industrial G-grade specifications. This extended temperature range qualifies R5F101GLAFB#10 for deployment in demanding environments such as factory automation controllers, motor drives, and outdoor industrial sensors where ambient thermal stress exceeds commercial-grade limits.
Which serial communication interfaces are supported by the R5F101GLAFB#10?
The R5F101GLAFB#10 supports multiple serial interfaces: up to 8 CSI (SPI-compatible) channels, up to 4 UART/LIN channels (with full LIN 2.2 support), and up to 10 I²C/Simplified I²C channels. These are implemented in hardware with independent clock sources and configurable pin mappings - allowing R5F101GLAFB#10 to simultaneously manage sensor buses, host communication, and actuator control without software bit-banging.
How does the R5F101GLAFB#10 achieve ultra-low power consumption?
The R5F101GLAFB#10 achieves ultra-low power via three optimized modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE (low-power background ADC conversion). Its on-chip high-accuracy oscillator (±1.0% over 1.8–5.5 V) eliminates external crystals for most functions, and the RL78 core's voltage-scalable operation enables dynamic power scaling - all contributing to multi-year battery life in R5F101GLAFB#10-based designs.
