Renesas R5F12047GSP#30

Overview

R5F12047GSP#30 from Renesas Electronics is a 16-pin, 4 KB code flash, 1 KB RAM RL78/G15 16-bit microcontroller for industrial applications (−40°C to +105°C), featuring an 8-channel 16-bit timer array, 7-channel 8/10-bit A/D converter, 1-channel comparator, UART, two simplified SPI (CSI) channels, and two simplified I²C channels - deployed in smart sensors and low-power industrial control nodes.

For engineers reviewing the R5F12047GSP#30 datasheet, R5F12047GSP#30 pinout, R5F12047GSP#30 application, or R5F12047GSP#30 equivalent, this page delivers verified package mapping (16-pin SSOP, 0.65 mm pitch), confirmed peripheral allocation (P00–P07, P40–P41, P121–P125, P137), real-time power mode behavior (HALT/STOP), and validated alternative selection guidance aligned with Renesas' documented RL78/G15 family variants.

Technical Context

The R5F12047GSP#30 implements the RL78-S2 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space, supporting instruction execution times from 0.0625 μs (16 MHz high-speed on-chip oscillator) to 1.0 μs (1 MHz). It integrates a selectable power-on-reset circuit with four voltage thresholds (2.25 V to 4.45 V) and operates from a single 2.4–5.5 V supply.

Its timing subsystem includes a high-speed on-chip oscillator (1–16 MHz, ±1.0% accuracy at −20°C to +85°C), low-speed on-chip oscillator (15 kHz), and external crystal support (X1/X2, 1–12 MHz). The device supports background data flash writes only via self-programming - not BGO - requiring code flash suspension during rewrite operations.

FAQ

What is the maximum operating frequency of the R5F12047GSP#30?

The R5F12047GSP#30 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, yielding a minimum instruction execution time of 0.0625 μs. External crystal operation is rated up to 12 MHz (X1/X2), and external clock input (EXCLK) accepts up to 16 MHz. All timing specifications assume VDD = 2.4–5.5 V and TA = −40°C to +105°C.

Does the R5F12047GSP#30 support background data flash rewriting?

No, the R5F12047GSP#30 does not support background operation (BGO) for data flash. Instructions cannot be executed from code flash memory while data flash is being rewritten. The device requires code flash suspension during data flash programming, making it unsuitable for real-time firmware updates without careful state management.

How many analog input channels does the R5F12047GSP#30 provide?

The R5F12047GSP#30 provides 7 analog input channels (ANI0 through ANI6), all accessible on dedicated pins (P00, P01, P02, P03, P04, P05, P06, P07) with 8/10-bit resolution and support for internal 0.815 V reference voltage. This matches the 16-pin SSOP variant's function allocation per Renesas' RL78/G15 documentation.

What package type and pin pitch does the R5F12047GSP#30 use?

The R5F12047GSP#30 uses a 16-pin plastic SSOP package (4.4 × 5.0 mm) with 0.65-mm pin pitch, as indicated by the "SP" suffix and confirmed in Table 1-1 of the datasheet. It is distinct from the HWQFN variant (NA suffix) and shares footprint compatibility with other RL78/G15 16-pin SSOP devices like R5F12048GSP#30.

Can the R5F12047GSP#30 operate reliably at +105°C ambient temperature?

Yes, the R5F12047GSP#30 is qualified for industrial applications with an operating ambient temperature range of −40°C to +105°C (G grade). Its electrical characteristics, including oscillator accuracy (±1.0% at −20°C to +85°C), flash endurance, and I/O drive strength, are guaranteed across this full range per Renesas' datasheet Rev.1.40.
