Product details
Overview
R5F102A7GSP#10 from Renesas Electronics is a 30-pin LSSOP packaged RL78/G12 16-bit microcontroller designed for low-power industrial embedded control. It integrates 16 KB code flash, 2 KB data flash, 2 KB RAM, 10-bit A/D converter (8 channels), and dual-channel DMA - operating across –40°C to +105°C with 1.8–5.5 V supply, targeting smart sensors and programmable logic controllers.
For engineers reviewing the R5F102A7GSP#10 datasheet, R5F102A7GSP#10 pinout, R5F102A7GSP#10 application, or R5F102A7GSP#10 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +105°C), on-chip data flash endurance (1,000,000 rewrites), high-accuracy ±1.0% on-chip oscillator (–20°C to +85°C), and support for UART/CSI/I²C serial interfaces in a 30-pin LSSOP package.
Technical Context
The R5F102A7GSP#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, delivering 31 DMIPS at 24 MHz. Its power management includes HALT, STOP, and SNOOZE modes enabling true low-power operation (63 μA/MHz), while the integrated voltage detector offers 12-level reset/interrupt thresholds for robust system supervision.
It features a dedicated 15 kHz low-speed on-chip oscillator for watchdog and interval timer operation, alongside a high-speed on-chip oscillator selectable from 1–24 MHz with ±1.0% accuracy over –20°C to +85°C. Peripheral I/O redirection (PIOR) enables flexible pin assignment for UART0, CSI00, IICA0, and TAU0 timer outputs without hardware redesign.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F102A8GSP#10 | 8 KB code flash, 512 B RAM, same 30-pin LSSOP package and G-grade temp range | Suitable for simpler control tasks with smaller firmware footprints and reduced RAM requirements | Select when application firmware size is under 7 KB and no background data flash writes are needed |
| R5F103A7GSP#10 | No data flash, no DMA, no CRC/memory guards; otherwise identical pinout and peripheral set | Lacks nonvolatile parameter storage and hardware error detection - requires external EEPROM and careful SW validation | Choose only if cost reduction outweighs reliability and field-update capability requirements |
Compared with R5F102A7GSP#10, R5F102A8GSP#10 trades flash/RAM capacity for lower cost in resource-light applications, while R5F103A7GSP#10 removes critical reliability features (data flash, DMA, CRC) - making it unsuitable for applications requiring field firmware updates or functional safety compliance.

FAQ
What is the maximum operating frequency and instruction throughput of the R5F102A7GSP#10?
The R5F102A7GSP#10 achieves a maximum system clock of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS of processing performance. Its minimum instruction execution time is 0.04167 μs at 24 MHz, enabled by the RL78's 3-stage pipeline CISC architecture - sufficient for real-time control loops in motor drives and sensor fusion applications.
Does the R5F102A7GSP#10 support in-field firmware updates via its data flash memory?
Yes, the R5F102A7GSP#10 includes 2 KB of data flash memory rated for 1,000,000 erase/write cycles at VDD = 1.8–5.5 V, with background operation (BGO) allowing program execution during flash writes. This enables safe, atomic firmware updates and parameter storage without halting system operation - a key capability confirmed in the R01DS0193EJ0250 datasheet.
What are the supported serial communication interfaces on the R5F102A7GSP#10?
The R5F102A7GSP#10 provides one UART channel (UART0), one simplified SPI interface (CSI00), and one simplified I²C interface (IICA0) - all configurable via the Peripheral I/O Redirection Register (PIOR). Unlike 20-/24-pin variants, the 30-pin R5F102A7GSP#10 does not support multiple CSI or I²C channels, limiting it to single-bus peripheral expansion.
How does the R5F102A7GSP#10 handle power supply supervision and reset conditions?
The R5F102A7GSP#10 integrates an on-chip power-on-reset (POR) circuit (1.51 V typical) and a 12-level voltage detector (LVD) with programmable rising/falling thresholds (1.88–4.06 V). It supports reset generation or interrupt on undervoltage events - critical for maintaining state integrity in industrial power supplies and battery-backed systems where brown-out resilience is mandatory.
Is the R5F102A7GSP#10 pin-compatible with other RL78/G12 family members in the same package?
The R5F102A7GSP#10 shares the 30-pin LSSOP package and pin configuration with other R5F102Ax and R5F103Ax variants (e.g., R5F102A8GSP#10, R5F103A7GSP#10), but functional pin mapping differs due to peripheral enablement - notably, R5F103x parts lack data flash, DMA, and CRC. Pin compatibility exists physically, but firmware and schematic validation is required when substituting across R5F102/R5F103 subfamilies.
