Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F102AAASP#30 | Same 30-pin LSSOP package, 16 KB code flash, 2 KB data flash, but rated for -40°C to +85°C (A-grade) instead of +105°C | Lacks extended temperature qualification - unsuitable for under-hood or high-ambient industrial enclosures | Select when cost-sensitive consumer-grade operation suffices and ambient temperature remains ≤85°C |
| R5F103A9GSP#30 | Same 30-pin LSSOP and G-grade temperature range, but omits data flash and DMA; replaces CRC with basic safety features only | No background data flash writes or hardware-accelerated integrity checking - limits secure update and logging capability | Choose where firmware updates occur infrequently and real-time CRC validation is unnecessary |
Compared with R5F102A9GSP#30, R5F102AAASP#30 trades industrial temperature margin for lower cost, while R5F103A9GSP#30 removes data flash and DMA to reduce silicon area - both require revalidation of thermal, update, and real-time performance margins in production designs.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for R5F102A9GSP#30?
The R5F102A9GSP#30 achieves a maximum operating frequency of 24 MHz using its high-accuracy on-chip oscillator, delivering 31 DMIPS at that speed. This performance level is validated across the full industrial temperature range (-40°C to +105°C) and 1.8–5.5 V supply, making R5F102A9GSP#30 suitable for deterministic real-time control tasks in thermally demanding environments.
Does R5F102A9GSP#30 support background data flash programming while executing code from main flash?
Yes, R5F102A9GSP#30 supports Background Operation (BGO) for data flash, allowing the CPU to execute instructions from code flash memory while simultaneously rewriting the 2 KB data flash area. This capability enables seamless firmware parameter updates, calibration storage, or event logging without halting application execution - a key feature confirmed in the R01DS0193EJ0250 datasheet Section 1.1.
How many analog input channels and what A/D resolution does R5F102A9GSP#30 provide?
R5F102A9GSP#30 integrates an 8-channel, 10-bit successive-approximation A/D converter with internal 1.45 V reference voltage and integrated temperature sensor. Channels include ANI0–ANI3 and ANI16–ANI19, all operating across the full 1.8–5.5 V supply range - enabling direct ratiometric measurements using AVREFP/AVREFM pins without external references.
What low-power modes are available on R5F102A9GSP#30 and how do they differ?
R5F102A9GSP#30 offers HALT, STOP, and SNOOZE modes. HALT stops the CPU clock but retains RAM and register contents; STOP disables all clocks including peripherals and reduces current to ~0.5 µA; SNOOZE allows selected peripherals (e.g., UART, ADC) to operate while CPU sleeps - ideal for periodic sensor sampling with minimal wake latency. All modes are fully supported in the -40°C to +105°C range.
Is R5F102A9GSP#30 pin-compatible with other RL78/G12 30-pin variants like R5F102AAASP#30?
Yes, R5F102A9GSP#30 shares identical 30-pin LSSOP pinout and electrical characteristics with other RL78/G12 30-pin members including R5F102AAASP#30 and R5F103A9GSP#30. Pin functions, drive strength, and peripheral mappings match per the RL78/G12 User's Manual - enabling drop-in replacement where functional requirements (e.g., data flash, temperature grade) align.
