Product details
Overview
R5F12048GSP#10 from Renesas Electronics is an RL78/G15 16-pin, 8 KB flash, 1 KB RAM, industrial-grade 16-bit microcontroller operating from 2.4 to 5.5 V. It integrates an 8-channel 16-bit timer, 7-channel 8/10-bit ADC, dual simplified I²C, UART, and CSI interfaces, and supports −40°C to +105°C operation for motor control and sensor interface applications.
For engineers reviewing the R5F12048GSP#10 datasheet, R5F12048GSP#10 pinout, R5F12048GSP#10 application, or R5F12048GSP#10 equivalent, key selection criteria include its 16-pin SSOP package, 8 KB code flash with self-programming, 1 KB data flash rated for 1M rewrites, and integrated high-speed on-chip oscillator (1–16 MHz, ±1.0% accuracy at −20°C to +85°C).
Technical Context
The R5F12048GSP#10 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, 1 MB address space, and four banks of 8-bit general-purpose registers. Its clock system combines a selectable high-speed on-chip oscillator (1–16 MHz), low-speed 15 kHz on-chip oscillator, and external crystal support (X1/X2, up to 12 MHz) with programmable power-on-reset levels.
Peripheral integration includes a 12-bit interval timer, watchdog timer, BCD correction circuit, and two comparator channels. The device supports background operation only for code flash programming - data flash rewriting blocks instruction execution from code flash memory, requiring careful state management during firmware updates.

FAQ
What is the maximum operating frequency of the R5F12048GSP#10 high-speed on-chip oscillator?
The R5F12048GSP#10 high-speed on-chip oscillator supports frequencies up to 16 MHz, selectable via option byte bits 0–2. At 16 MHz operation, the minimum instruction execution time is 0.0625 μs. Frequency accuracy is ±1.0% over −20°C to +85°C ambient, meeting industrial timing stability requirements without external crystals.
Does the R5F12048GSP#10 support background data flash rewriting while executing code from flash memory?
No, the R5F12048GSP#10 does not support background operation (BGO) for data flash rewriting. During data flash write/erase operations, instruction execution from code flash memory is halted. This requires firmware to manage critical sections and disable interrupts during flash updates to prevent corruption or lockup.
How many analog input channels are available on the R5F12048GSP#10, and what resolution do they support?
The R5F12048GSP#10 provides 7 analog input channels (ANI0–ANI6) supporting configurable 8-bit or 10-bit resolution. Conversion is referenced to VDD (2.4–5.5 V) or internal 0.815 V reference, enabling accurate sensor measurements across its full industrial temperature range without external reference ICs.
What package type and pin count does the R5F12048GSP#10 use?
The R5F12048GSP#10 uses a 16-pin plastic SSOP package (4.4 × 5.0 mm, 0.65-mm pitch). The "SP" suffix in the part number explicitly denotes this SSOP configuration, and the "#10" packaging specification indicates tray delivery for automated assembly.
Can the R5F12048GSP#10 operate reliably at 125°C ambient temperature?
No, the R5F12048GSP#10 is rated for −40°C to +105°C ambient operation (G-grade). For +125°C environments, the functionally identical R5F12048MSP#10 (M-grade) must be used. Both share identical peripherals and pinout, differing only in temperature qualification and oscillator accuracy specifications above +105°C.
