Product details
Overview
R5F1176AGSP#30 from Renesas Electronics is a 30-pin, 8 KB flash, 0.7 KB RAM RL78/I1D 16-bit microcontroller with ultra-low power consumption (58.3 μA/MHz), 1.6–3.6 V operation, and industrial temperature range (−40 to +105°C). It integrates a 12-bit A/D converter (12 channels), 4-channel operational amplifier, 2-channel comparator, real-time clock, UART, I²C, and simplified SPI for sensor interface and control in battery-powered industrial monitoring systems.
For engineers reviewing the R5F1176AGSP#30 datasheet, R5F1176AGSP#30 pinout, R5F1176AGSP#30 application, or R5F1176AGSP#30 equivalent, this page delivers verified technical context, package mapping, functional pin roles, low-power mode behavior, and validated alternative options - all grounded in Renesas R01DS0244EJ0241 Rev. 2.41 specifications.
Technical Context
The R5F1176AGSP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs at 24 MHz high-speed on-chip oscillator or 66.6 μs at 15 kHz low-speed mode). It supports self-programming with boot swap and flash shield window functions for secure firmware updates.
Its peripheral set includes a Data Transfer Controller (DTC) with 19 activation sources, Event Link Controller (ELC) with 17 event inputs and 7 trigger outputs, and dual clock domains: main system clock (up to 20 MHz via X1 or 24 MHz on-chip oscillator) and subsystem clock (32.768 kHz XT1 oscillator for RTC).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F117AAGSP#30 | 16 KB flash, 3 KB RAM, same 30-pin LSSOP package and peripheral set | Supports larger firmware images and extended data logging buffers | Select when firmware exceeds 8 KB or additional RAM is required for complex algorithms |
| R5F11768GSP#30 | Identical 8 KB flash, 0.7 KB RAM, but lacks ANI5–ANI7 and AMP1±/AMP1O analog resources | Reduced analog channel count limits multi-sensor front-end capability | Choose only if design uses ≤6 analog inputs and no second op-amp stage is needed |
Compared with R5F1176AGSP#30, R5F117AAGSP#30 offers scalable memory headroom while maintaining identical I/O and analog functionality, whereas R5F11768GSP#30 sacrifices analog flexibility for cost-sensitive applications with minimal sensor count.

FAQ
What is the maximum operating frequency of the R5F1176AGSP#30?
The R5F1176AGSP#30 supports a maximum system clock frequency of 24 MHz using its high-speed on-chip oscillator, or up to 20 MHz when driven by an external crystal (X1) at VDD ≥ 2.7 V. Instruction execution time reaches 0.04167 μs under 24 MHz operation, enabling real-time response in control loops and sensor sampling.
Does the R5F1176AGSP#30 support hardware debugging during development?
Yes, the R5F1176AGSP#30 includes an on-chip debug function with trace capability for development and evaluation. However, Renesas explicitly cautions against using this feature in mass-produced units due to potential flash memory wear-out beyond guaranteed rewrite cycles, which may compromise long-term reliability.
How many analog input channels does the R5F1176AGSP#30 provide?
The R5F1176AGSP#30 provides 12 analog input channels (ANI2–ANI7 and ANI10–ANI13), confirmed in the RL78/I1D datasheet Section 1.6 for 30-pin products. This enables concurrent measurement of multiple sensors such as thermistors, potentiometers, and current shunts without external multiplexing.
What is the purpose of the REGC pin on the R5F1176AGSP#30?
The REGC pin on the R5F1176AGSP#30 connects to an external 0.47–1 μF capacitor to stabilize the internal voltage regulator. This capacitor is mandatory per Renesas datasheet Caution 1; omitting it risks unstable operation or failure to enter low-power modes reliably.
Can the R5F1176AGSP#30 operate across the full industrial temperature range?
Yes, the R5F1176AGSP#30 is rated for operation from −40°C to +105°C (industrial grade "G" suffix), with electrical specifications validated across this range. At temperatures above +85°C, only HS (high-speed main) flash operation mode is permitted, and regulator mode must remain enabled (MCSEL = 0) per datasheet Caution 4.
