Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104BAANA#U0 | 32-pin HWQFN, 16 KB flash, 2.5 KB RAM, same core/peripherals - adds 2 more I/O pins and exposed thermal pad | Better thermal performance and routing density for space-constrained PCBs; requires rework of land pattern | Select when board area is limited and thermal dissipation >150 mW is expected |
| STM8L152C6T6 | 8-bit STM8 core, 32 KB flash, 2 KB RAM, 12-bit ADC, 3.6 μA STOP mode - lower performance but superior ultra-low-power STOP current | Preferred for simple polling-based sensor nodes where 16-bit math or complex peripherals are unnecessary | Choose when application fits 8-bit architecture and sub-5 μA deep-sleep is mandatory |
Compared with R5F104BAANA#U0, the R5F104AAASP#30 offers identical functionality in a through-hole-compatible LSSOP package ideal for manual assembly and prototyping, while the STM8L152C6T6 trades RL78's advanced ELC and data flash endurance for deeper sleep current - making it suitable only for minimal-feature, ultra-long-life deployments.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104AAASP#30?
The R5F104AAASP#30 operates up to 32 MHz with its high-speed on-chip oscillator, delivering 44 DMIPS of processing performance. This enables real-time execution of PID control algorithms, sensor fusion, and protocol stacks such as Modbus RTU or basic LIN without external acceleration. The RL78 core maintains consistent timing across voltage and temperature ranges due to its adaptive pipeline design.
Does the R5F104AAASP#30 include on-chip debug capability, and what interface does it use?
Yes, the R5F104AAASP#30 includes full on-chip debug functionality accessible via the single-wire debug interface using pins P40 (TOOL0) and P137 (INTP0). This allows non-intrusive breakpoints, register inspection, and flash programming without requiring dedicated JTAG pins - reducing pin count and simplifying debug header design for the R5F104AAASP#30.
How many analog input channels does the R5F104AAASP#30 support, and what reference options are available?
The R5F104AAASP#30 supports 8 analog input channels (ANI0–ANI7) with 10-bit resolution. It provides internal 1.45 V reference voltage and accepts external references on AVREFP/AVREFM pins, enabling ratiometric measurements that reject supply noise. The ADC operates across the full 1.6–5.5 V VDD range, making it compatible with both 3.3 V and 5 V systems without external scaling.
What low-power modes are available on the R5F104AAASP#30, and what is the typical current draw in each?
The R5F104AAASP#30 supports HALT (66 μA/MHz), STOP (0.60 μA), and SNOOZE modes. In STOP mode with only RTC and LVD active, current draw is 0.60 μA - sufficient for decade-scale operation on a CR2032 cell. SNOOZE mode allows selected peripherals (e.g., ADC, UART) to operate while CPU sleeps, drawing ~12 μA during background conversions.
Is the R5F104AAASP#30 pin-compatible with other RL78/G14 variants, and what package options share the same footprint?
No, the R5F104AAASP#30 uses a 30-pin LSSOP package (PLSP0030JB-B) with 0.65 mm pitch, which is not pin-compatible with 32-pin HWQFN, 40-pin HWQFN, or 44-pin LQFP variants. Only other 30-pin LSSOP members of the RL78/G14 family - such as R5F104ACASP#30 or R5F104ADASP#30 - share identical mechanical and electrical pinout, differing only in flash/RAM size and peripheral enablement.
