Product details
Overview
R5F117A8GSP#30 from Renesas Electronics is an RL78/I1D 8-bit microcontroller designed for ultra-low-power industrial applications. It features 8 KB flash memory, 0.7 KB RAM, 12-channel 8/12-bit A/D converter, 4-channel operational amplifier, and operates across -40°C to +105°C with 1.6 V to 3.6 V supply. It targets battery-powered sensor nodes and smart actuators requiring RTC, analog signal conditioning, and serial communication.
For engineers reviewing the R5F117A8GSP#30 datasheet, R5F117A8GSP#30 pinout, R5F117A8GSP#30 application, or R5F117A8GSP#30 equivalent, key selection criteria include its 30-pin LSSOP package, integrated op-amps and comparators, low-power STOP/HALT modes (0.64 μA), and support for UART + simplified I²C + CSI interfaces in a single-chip solution.
Technical Context
The R5F117A8GSP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs at 24 MHz to 66.6 μs at 15 kHz). Its clock system integrates high-speed (up to 24 MHz ±1.0%), middle-speed (up to 4 MHz), and low-speed (15 kHz) on-chip oscillators, plus external crystal support via X1/X2 and XT1/XT2 pins.
Power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 12-level LVD, and regulator control via REGC pin. Peripheral integration comprises 4× 16-bit timers, 1× real-time clock (RTC2) with calendar and alarm, 2× comparators, and Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.

FAQ
What is the maximum operating frequency of the R5F117A8GSP#30?
The R5F117A8GSP#30 supports a maximum system clock frequency of 24 MHz using its high-speed on-chip oscillator. When using external crystal (X1), the maximum main system clock is 20 MHz under 2.7–3.6 V supply conditions. Instruction execution time ranges from 0.04167 μs (24 MHz) to 66.6 μs (15 kHz), configurable per application power/performance needs.
Does the R5F117A8GSP#30 support hardware debugging during development?
Yes, the R5F117A8GSP#30 includes an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. However, Renesas explicitly cautions against using this debug function in mass-produced end products due to potential flash memory wear-out beyond guaranteed rewrite cycles. For production units, debug functionality should be disabled or removed from firmware.
How many analog input channels does the R5F117A8GSP#30 support?
The R5F117A8GSP#30 supports 12 analog input channels (ANI2 through ANI13), as confirmed in the RL78/I1D datasheet Section 1.6 for 30-pin devices. These channels feed into the 8/12-bit A/D converter and can also serve as inputs to the four integrated operational amplifiers (AMP0–AMP3) and two comparators (IVCMP0/IVCMP1).
What is the purpose of the REGC pin on the R5F117A8GSP#30?
The REGC pin on the R5F117A8GSP#30 connects to an external 0.47–1 μF capacitor tied to VSS to stabilize the internal voltage regulator. This capacitor is mandatory for reliable operation; omitting it may cause erratic behavior or failure to exit reset. The absolute maximum voltage on REGC is limited to 2.8 V or VDD + 0.3 V, whichever is lower.
Can the R5F117A8GSP#30 operate from a 1.8 V supply?
Yes, the R5F117A8GSP#30 is fully specified for operation from 1.6 V to 3.6 V, including 1.8 V. At 1.8 V, the high-speed on-chip oscillator accuracy degrades to ±5.0%, and maximum main system clock frequency is reduced to 8 MHz. All peripherals-including A/D, op-amps, and timers-remain functional within datasheet limits at this voltage.
