Product details
Overview
R5F11768GSP#30 from Renesas is an RL78/I1D 8-bit microcontroller designed for ultra-low-power industrial applications, featuring 8 KB code flash, 2 KB data flash, 0.7 KB RAM, 20-pin LSSOP package, and operation from -40°C to +105°C. It integrates a 24 MHz high-accuracy on-chip oscillator (±1.0%), 6-channel 8/12-bit ADC, two comparators, four operational amplifiers, UART, simplified SPI (CSI), and simplified I²C - enabling compact sensor interface and battery-powered control systems.
For engineers reviewing the R5F11768GSP#30 datasheet, R5F11768GSP#30 pinout, R5F11768GSP#30 application, or R5F11768GSP#30 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases in industrial sensing and low-power HMI, and confirmed alternative options with documented functional and packaging differences.
Technical Context
The R5F11768GSP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs at 24 MHz or 66.6 μs at 15 kHz). Its power management includes HALT, STOP, and SNOOZE modes, achieving 58.3 μA/MHz active current and 0.64 μA RTC+LVD retention current.
Peripheral integration centers on analog signal conditioning: dual comparators with window mode, four op-amps (AMP0–AMP3) with configurable inputs/outputs, and a 6-channel ADC supporting internal 1.45 V reference and temperature sensor. Serial connectivity is limited to one CSI channel, one UART, and one simplified I²C channel - consistent with its 20-pin LSSOP footprint and targeted role in space-constrained embedded nodes.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F11768GSP#30?
The R5F11768GSP#30 features a high-speed on-chip oscillator adjustable up to 24 MHz with ±1.0% accuracy over -20°C to +85°C and 1.8–3.6 V supply. At 1.6–1.8 V, accuracy degrades to ±5.0%, and at +85–+105°C, it is ±2.0%. This oscillator serves as the default clock source after reset and enables rapid startup without external crystals.
Does R5F11768GSP#30 support UART communication, and which pins are assigned?
Yes, R5F11768GSP#30 supports one UART channel. Transmit (TxD0) is assigned to P54, and receive (RxD0) is assigned to P55. Both pins also support I²C data (SDA00) and external interrupt (INTP1/INTP2), allowing flexible routing via peripheral I/O redirection registers - though UART functionality is fixed to these pins in default configuration.
How much RAM is available on R5F11768GSP#30, and is any reserved for system functions?
R5F11768GSP#30 includes 0.7 KB of on-chip RAM. A portion is reserved for the Flash Self-Programming Library - specifically, RAM starting at address FF300H is used during data flash rewriting. This allocation is documented in Renesas' R20UT2944 library manual and must be excluded from user variable placement in linker scripts.
Can R5F11768GSP#30 drive a piezoelectric buzzer directly, and what is the output capability?
Yes, R5F11768GSP#30 supports direct buzzer drive via PCLBUZ0 on P31, generating frequencies from 2.44 kHz to 10 MHz using the main system clock or 256 Hz to 32.768 kHz using the subsystem clock. The pin supports CMOS-level output only - external driver circuitry is required for high-current or high-voltage buzzers.
What analog peripherals are integrated into R5F11768GSP#30, and how are they mapped to pins?
R5F11768GSP#30 integrates a 6-channel 8/12-bit ADC, two comparators (IVCMP0/IVCMP1), and four operational amplifiers (AMP0–AMP3). Pin mapping includes: P12 (ANI2/AMP0+), P13 (ANI3/AMP0−), P14 (ANI4/IVCMP0/AMP0O), P20–P22 (ANI13/AMP3+ etc.). All analog functions share the same AVDD/AVSS domain and require proper decoupling per datasheet cautions.
