Product details
Overview
R5F12018GSP#10 from Renesas Electronics is an RL78/G15 10-pin LSSOP microcontroller with 8 KB code flash, 1 KB RAM, and 1 KB data flash, operating at 2.4–5.5 V. It integrates an 8/10-bit ADC (4 channels), two simplified I²C interfaces, one UART, two CSI (SPI-compatible) channels, eight 16-bit timer channels, and a watchdog timer - deployed in industrial sensor nodes and low-power control modules.
For engineers reviewing the R5F12018GSP#10 datasheet, R5F12018GSP#10 pinout, R5F12018GSP#10 application, or R5F12018GSP#10 equivalent, key selection criteria include its −40°C to +105°C industrial temperature rating, 10-pin LSSOP package with 0.65-mm pitch, high-speed on-chip oscillator accuracy of ±1.0% (−20°C to +85°C), and support for background data flash rewrites only via external host interface (BGO not supported).
Technical Context
The R5F12018GSP#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling minimum instruction execution time of 0.0625 μs at 16 MHz. Its clock system combines selectable high-speed on-chip oscillator (1–16 MHz), low-speed on-chip oscillator (15 kHz), and optional external crystal (X1/X2, up to 12 MHz) or EXCLK input (up to 16 MHz).
Power management includes HALT and STOP modes, selectable power-on-reset (SPOR) with four voltage thresholds, and dedicated reset pin (P125). Peripheral I/O redirection registers (PIOR) enable flexible pin function assignment, including multiplexed timer outputs (TI0x/TO0x), serial interfaces (CSI00/CSI01, IIC00/IICA0, UART0), and analog inputs (ANI0–ANI3) with internal reference (0.815 V).

FAQ
What is the maximum operating frequency of the R5F12018GSP#10?
The R5F12018GSP#10 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, yielding a minimum instruction execution time of 0.0625 μs. External crystal (X1/X2) or EXCLK input can also drive the system clock up to 12 MHz or 16 MHz respectively, subject to oscillator stability and configuration register settings.
Does the R5F12018GSP#10 support background data flash rewriting?
No, the R5F12018GSP#10 does not support background operation (BGO) for data flash rewriting. During data flash programming or erasure, the CPU cannot execute instructions from code flash memory - requiring careful state management and interruption handling in firmware design.
What analog input channels are available on the R5F12018GSP#10?
The R5F12018GSP#10 provides four analog input channels: ANI0, ANI1, ANI2, and ANI3 - accessible on pins P01, P02, P03, and P04 respectively. All support 8/10-bit resolution and share the internal 0.815 V reference voltage (IVREF0) or external reference selection.
Can the R5F12018GSP#10 operate across the full industrial temperature range?
Yes, the R5F12018GSP#10 is rated for operation from −40°C to +105°C (G-grade), meeting industrial ambient requirements. Its high-speed on-chip oscillator maintains ±1.0% accuracy between −20°C and +85°C, and ±1.5% across the full −40°C to +105°C range.
How many serial communication interfaces does the R5F12018GSP#10 integrate?
The R5F12018GSP#10 integrates three serial interface types: one UART channel (RxD0/TxD0), two simplified I²C (IIC00/IICA0) channels, and two CSI (SPI-compatible) channels (CSI00/CSI01) - all configurable via peripheral I/O redirection registers for flexible pin assignment.
