Product details
Overview
R5F10269GSM#35 from Renesas is a 20-pin RL78/G12 16-bit microcontroller with 12 KB code flash, 2 KB data flash, and 768 B RAM, operating at 1.8–5.5 V and rated for –40°C to +105°C industrial use. It integrates a 24 MHz high-accuracy (±1.0%) on-chip oscillator, 10-bit 11-channel ADC, UART/CSI/I²C serial interfaces, 4-channel 16-bit TAU timer, and DMA controller-designed for battery-powered sensor nodes and industrial control panels requiring low-power operation and embedded firmware update capability.
For engineers reviewing the R5F10269GSM#35 datasheet, R5F10269GSM#35 pinout, R5F10269GSM#35 application, or R5F10269GSM#35 equivalent, key selection criteria include its G-grade temperature rating, integrated 2 KB data flash for field firmware updates, 2-channel DMA for efficient peripheral-to-memory transfers, TSSOP20 package compatibility with space-constrained PCBs, and support for HALT/STOP/SNOOZE low-power modes down to 63 μA/MHz.
Technical Context
The R5F10269GSM#35 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction timing (0.04167 μs min @ 24 MHz). Its clock system combines a ±1.0% accurate 1–24 MHz high-speed on-chip oscillator with external crystal support (1–20 MHz) and a 15 kHz low-speed oscillator for watchdog and interval timing.
Peripheral integration includes two simplified SPI (CSI) channels, two simplified I²C channels, one UART channel, CRC calculation unit, RAM guard, SFR guard, and programmable buzzer/clock output. All functions are validated for G-grade operation (–40°C to +105°C), distinguishing it from A/D-grade variants.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F10269GSM#35?
The R5F10269GSM#35 features a high-speed on-chip oscillator with selectable frequencies up to 24 MHz and ±1.0% accuracy over –20°C to +85°C, and ±2.0% over –40°C to +105°C. This specification is confirmed for G-grade parts and enables precise timing without external crystals in many applications, reducing BOM cost and board area. The oscillator is factory-trimmed and does not require user calibration.
Does R5F10269GSM#35 support background data flash rewriting while executing code from main flash?
Yes, the R5F10269GSM#35 supports Background Operation (BGO) for data flash. While the CPU executes instructions from code flash memory, the data flash can be rewritten - enabling seamless firmware updates, parameter storage, or logging without halting application execution. This capability is enabled by dedicated hardware and requires use of the RL78 Family Data Flash Library Type04.
What are the key differences between R5F10269GSM#35 and R5F10369GSM#35?
The R5F10269GSM#35 includes 2 KB data flash, 2-channel DMA, CRC engine, RAM guard, and SFR guard - features absent in the R5F10369GSM#35. Additionally, the R5F10269GSM#35 offers higher oscillator accuracy (±1.0% vs ±5.0%) and more serial interfaces (2 CSI + 2 simplified I²C vs 1 CSI only). These differences make R5F10269GSM#35 suitable for applications requiring field firmware updates and enhanced functional safety.
Which package type and pin count does R5F10269GSM#35 use?
The R5F10269GSM#35 uses a 20-pin TSSOP package (PTSP0020JI-A) with 4.4 × 6.5 mm body and 0.65-mm pitch. This surface-mount package supports automated assembly and provides adequate thermal performance for industrial ambient conditions up to +105°C. Pinout matches other RL78/G12 20-pin variants, enabling layout reuse across memory-configured family members.
Can R5F10269GSM#35 operate reliably at 1.8 V supply voltage?
Yes, the R5F10269GSM#35 is fully specified to operate at 1.8 V minimum supply voltage across its entire –40°C to +105°C temperature range. At 1.8 V, it supports up to 8 MHz operation in LS mode and maintains all peripheral functionality including ADC, timers, and serial interfaces - enabling direct integration with 1.8 V logic families and ultra-low-power battery systems.
