FAQ
What is the maximum operating frequency and corresponding performance of the R5F104GLGNA#20?
The R5F104GLGNA#20 operates at up to 32 MHz with the high-speed on-chip oscillator, delivering 44 DMIPS of processing performance. Its RL78 CPU core supports variable instruction execution times-from 0.03125 µs at full speed to 30.5 µs in ultra-low-speed 32.768 kHz mode-enabling dynamic power/performance scaling. This makes the R5F104GLGNA#20 suitable for both responsive real-time control and extended battery-life applications.
Does the R5F104GLGNA#20 support in-system programming and secure firmware updates?
Yes, the R5F104GLGNA#20 supports full in-system programming via its on-chip debug interface and self-programming capability with boot swapping. It includes flash shield window protection and block erase prohibition to prevent unauthorized rewriting. Background operation (BGO) allows code execution from flash while data flash is being rewritten-enabling safe, atomic firmware updates without halting system operation. This functionality is fully implemented in the R5F104GLGNA#20's 128 KB code flash and 8 KB data flash.
What analog features are integrated into the R5F104GLGNA#20, and how are they applied in sensor systems?
The R5F104GLGNA#20 integrates a 10-bit A/D converter with up to 16 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. It also includes an 8-bit D/A converter with two output channels and a programmable comparator. In sensor systems, these features enable direct acquisition of thermistor, pressure transducer, or current-sense amplifier outputs-with temperature compensation applied in real time using the on-die sensor. The R5F104GLGNA#20's analog subsystem eliminates need for external references or signal-conditioning ICs in many industrial monitoring designs.
How does the R5F104GLGNA#20 achieve ultra-low power consumption, and what are the key low-power modes?
The R5F104GLGNA#20 achieves ultra-low power via multiple hardware-optimized states: HALT mode draws 66 μA/MHz during active processing; STOP mode consumes just 0.60 μA while maintaining RTC and LVD operation; and SNOOZE mode allows selective peripheral activation (e.g., ADC conversion or UART receive) without waking the CPU. These modes are controlled by dedicated system registers and supported by automatic clock gating. The R5F104GLGNA#20's design enables multi-year operation on coin cells in wireless sensor nodes and battery-backed industrial controllers.
Is the R5F104GLGNA#20 pin-compatible with other RL78/G14 variants, and what package options exist?
The R5F104GLGNA#20 uses a 48-pin HWQFN (7 × 7 mm, 0.5 mm pitch) package with exposed die pad. Within the RL78/G14 family, all 48-pin HWQFN variants-including R5F104GAANA#20, R5F104GHGNA#20, and R5F104GLGNA#20-share identical pinouts and mechanical footprint. This enables hardware reuse across memory configurations. Other package options for this pin count include LFQFP (7 × 7 mm, 0.5 mm pitch), but those are not pin-compatible with the HWQFN variant of the R5F104GLGNA#20.
