Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101EAANA#20 | Same die, identical electrical specs, but shipped in embossed tape (reel) instead of tray | No functional difference; optimized for automated SMT assembly lines requiring reel-fed feeders | Select #20 for high-volume production; #00 preferred for prototyping and small-batch builds |
| R5F101ECANA#00 | Same 40-pin HWQFN package and 64 KB flash, but adds 4 KB data flash (vs. 4 KB in R5F101EAANA#00) and 3 KB RAM (vs. 2 KB) | Enables larger firmware-over-the-air buffers and extended runtime variable storage for complex state machines | Choose when additional RAM or data flash endurance (>1M cycles) is required; otherwise R5F101EAANA#00 offers optimal cost/performance balance |

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F101EAANA#00?
The R5F101EAANA#00 operates up to 32 MHz using its high-accuracy on-chip oscillator, achieving 41 DMIPS performance at 66 μA/MHz (2.112 mA total at 32 MHz). In STOP mode with only RTC and LVD active, it draws just 0.57 μA - a critical specification for multi-year battery operation in R5F101EAANA#00-based designs.
Does the R5F101EAANA#00 include an integrated temperature sensor, and how is it calibrated?
Yes, the R5F101EAANA#00 integrates a factory-calibrated temperature sensor usable via the ADC. It is accessible as an analog input channel and referenced to the internal 1.45 V bandgap voltage, enabling direct Celsius reading with ±2°C accuracy across –40°C to +85°C without external components - a feature confirmed in the R5F101EAANA#00 datasheet Section 1.1.
Can the R5F101EAANA#00 execute code while rewriting its data flash memory?
Yes, the R5F101EAANA#00 supports Background Operation (BGO) for data flash, allowing full CPU instruction execution from program memory during 4 KB data flash erase/write sequences. This enables seamless firmware updates and parameter logging without halting real-time tasks - a verified capability of the R5F101EAANA#00's flash library implementation.
What debug interface does the R5F101EAANA#00 support, and is external hardware required?
The R5F101EAANA#00 supports single-wire debug (SWD) via the dedicated TOOLRxD pin (P11), enabling full in-circuit debugging, flash programming, and real-time trace without JTAG headers. No external debug probe is mandatory - Renesas E2 studio and CS+ IDE integrate directly with the R5F101EAANA#00's on-chip debug circuitry.
Is the R5F101EAANA#00 pin-compatible with other RL78/G13 variants in the same 40-pin HWQFN package?
Yes, all RL78/G13 40-pin HWQFN variants - including R5F101EAANA#00, R5F101ECANA#00, and R5F101EDANA#00 - share identical pinouts and footprint. Memory size, data flash presence, and RAM capacity differ, but PCB layout and signal routing remain fully interchangeable across this package group.
