Renesas R5F1176AGSM#30

Overview

R5F1176AGSM#30 from Renesas Electronics is a 30-pin, TSSOP-packaged RL78/I1D 16-bit microcontroller designed for ultra-low-power industrial embedded applications. It integrates 8 KB flash memory, 2 KB data flash, 0.7 KB RAM, a 12-bit A/D converter with 12 input channels, two comparators, and four operational amplifiers - enabling sensor signal conditioning and real-time control in battery-powered or thermally constrained systems.

For engineers reviewing the R5F1176AGSM#30 datasheet, R5F1176AGSM#30 pinout, R5F1176AGSM#30 application, or R5F1176AGSM#30 equivalent, this device supports key design requirements including sub-1 μA STOP mode operation, ±1.0% high-speed on-chip oscillator accuracy (1.8–3.6 V), RTC calendar functionality, and hardware event linking via ELC for deterministic peripheral coordination without CPU intervention.

Technical Context

The R5F1176AGSM#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and support for multiply/divide/accumulate instructions. Its clock system combines a 24 MHz high-accuracy on-chip oscillator (±1.0% at −20 to +85°C), selectable middle-speed (4 MHz) and low-speed (15 kHz) internal clocks, and external crystal support (X1 up to 20 MHz, XT1 at 32.768 kHz).

Peripherals include a 4-channel 16-bit timer array, 12-bit interval timer, 4× 8-bit interval timers, UART0, simplified SPI (CSI00), simplified I²C (IIC00), DTC with 19 activation sources, and ELC supporting 17 event inputs and 7 trigger outputs - all operating within 1.6–3.6 V supply and −40 to +105°C ambient range.

FAQ

What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F1176AGSM#30?

The R5F1176AGSM#30 features a high-speed on-chip oscillator configurable up to 24 MHz with ±1.0% accuracy over −20 to +85°C at VDD = 1.8–3.6 V. At 1.6–1.8 V, accuracy degrades to ±5.0%. This oscillator serves as the primary clock source post-reset before switching to external crystals, eliminating need for external timing components in many designs.

Does R5F1176AGSM#30 support background data flash rewriting while executing application code?

Yes, the R5F1176AGSM#30 supports Background Operation (BGO) for its 2 KB data flash memory. This allows the CPU to execute instructions from program memory while simultaneously rewriting data flash - enabling seamless firmware updates, parameter logging, and calibration storage without halting real-time operations.

How many analog input channels and operational amplifiers does R5F1176AGSM#30 provide?

The R5F1176AGSM#30 provides 12 dedicated analog input channels (ANI0–ANI13, excluding ANI14/15) and four fully independent operational amplifiers (AMP0–AMP3). Each op-amp has dedicated +/− inputs and output pins, supporting configurations such as instrumentation amplifiers, active filters, and sensor biasing circuits.

What power modes and minimum current consumption does R5F1176AGSM#30 offer?

The R5F1176AGSM#30 offers HALT (58.3 μA/MHz), STOP (0.64 μA with RTC2 and LVD active), and SNOOZE modes. In STOP mode, only the real-time clock (RTC2) and low-voltage detector (LVD) remain powered - enabling multi-year battery operation in sensor and metering applications where periodic wake-up is required.

Is R5F1176AGSM#30 pin-compatible with other RL78/I1D variants in the same package?

Yes, the R5F1176AGSM#30 shares identical 30-pin TSSOP pinout and electrical characteristics with other RL78/I1D devices in the GSM package (e.g., R5F11768GSM#30, R5F117AAGSM#30). All share the same peripheral mapping, register layout, and debug interface - enabling hardware reuse across memory-variant designs.
