Product details
Overview
R5F10269ASM#15 from Renesas Electronics 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 delivering 31 DMIPS at 24 MHz. It integrates an ultra-low-power CPU core (63 μA/MHz), 10-bit 11-channel ADC, dual CSI/I²C serial interfaces, UART, 4-channel 16-bit TAU timer, and on-chip debug - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F10269ASM#15 datasheet, R5F10269ASM#15 pinout, R5F10269ASM#15 application, or R5F10269ASM#15 equivalent, key selection criteria include its 2 KB data flash with background operation, ±1.0% high-speed on-chip oscillator accuracy over –20 to +85°C, DMA support, CRC hardware, and AEC-Q100-unqualified but industrial-grade (–40 to +85°C) thermal rating.
Technical Context
The R5F10269ASM#15 implements the RL78 CISC CPU core with 3-stage pipeline and 1 MB address space, executing instructions in as little as 0.04167 µs at 24 MHz using the high-speed on-chip oscillator. Its peripheral set includes two CSI channels (SPI-compatible), two simplified I²C channels, one UART channel, and four 16-bit timer output channels supporting PWM generation.
Power management features HALT, STOP, and SNOOZE modes, while safety functions include CRC calculation unit, RAM guard, and SFR guard - all enabled by default in the R5F102 product line. The device uses a single-supply 1.8–5.5 V rail and supports different-potential interfacing (1.8/2.5/3.0 V logic) via configurable I/O buffers.

FAQ
What is the maximum operating frequency and instruction throughput of the R5F10269ASM#15?
The R5F10269ASM#15 operates at up to 24 MHz using its high-speed on-chip oscillator, achieving 31 DMIPS (Dhrystone MIPS) performance. Its minimum instruction execution time is 0.04167 µs at 24 MHz, and it supports system clock inputs up to 20 MHz via external crystal (X1/X2). The RL78 CPU core uses a 3-stage pipeline to deliver deterministic real-time response in control loops.
Does the R5F10269ASM#15 support background data flash rewriting while executing application code?
Yes, the R5F10269ASM#15 supports Background Operation (BGO) for its 2 KB data flash memory. This allows the CPU to execute instructions from program memory while simultaneously erasing or programming data flash sectors - essential for non-disruptive firmware updates and event logging. The R5F10269ASM#15 implements this using dedicated hardware control logic and interrupt-driven completion signaling.
What are the key differences between the R5F10269ASM#15 and the R5F10369ASM#15?
The R5F10269ASM#15 includes 2 KB data flash, ±1.0% oscillator accuracy, 2-channel DMA, hardware CRC, RAM guard, and SFR guard - features absent in the R5F10369ASM#15. In contrast, the R5F10369ASM#15 offers higher UART/CSI channel count but lacks data flash and safety peripherals. Both share identical pinout, package, and core architecture.
Can the R5F10269ASM#15 drive standard 5 V logic peripherals directly?
Yes - the R5F10269ASM#15 includes two N-ch open-drain I/O pins (P60 and P61) rated for 6 V tolerance, allowing direct interface with 5 V I²C buses and other 5 V peripherals without external level shifters. All other GPIOs operate at VDD-referenced logic levels (1.8–5.5 V), and their output drive strength is configurable per datasheet electrical specs.
Is the R5F10269ASM#15 qualified for automotive applications?
No - the R5F10269ASM#15 is specified for industrial and consumer applications with an operating range of –40°C to +85°C (A-grade). It is not AEC-Q100 qualified. For automotive use, Renesas offers G-grade variants (e.g., R5F10269GSM#15) rated to –40°C to +105°C, but those require separate qualification documentation and validation.
