Renesas R5F10269GSM#15

Overview

R5F10269GSM#15 from Renesas Electronics is a 20-pin TSSOP-packaged RL78/G12 16-bit microcontroller designed for industrial embedded control at extended temperature (–40°C to +105°C). It integrates 12 KB code flash, 2 KB data flash, 768 B RAM, 10-bit A/D converter (11 channels), and dual serial interfaces (2× CSI, 2× I²C, 1× UART) - enabling compact sensor node and motor control applications with on-the-fly data logging.

For engineers reviewing the R5F10269GSM#15 datasheet, R5F10269GSM#15 pinout, R5F10269GSM#15 application, or R5F10269GSM#15 equivalent, key selection criteria include its G-grade industrial temp rating, integrated 2 KB data flash with background operation (BGO), DMA support (2 channels), CRC hardware acceleration, and ultra-low power consumption (63 μA/MHz) in STOP/HALT modes.

Technical Context

The R5F10269GSM#15 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.04167 μs (@24 MHz high-speed on-chip oscillator) to 1 μs (@1 MHz). Its clock system combines a ±1.0% accurate 1–24 MHz high-speed on-chip oscillator (valid over –40°C to +105°C), 15 kHz low-speed on-chip oscillator, and external crystal input (X1/X2 up to 20 MHz).

Peripheral integration includes TAU0 16-bit timer (4 channels), window watchdog timer, 12-bit interval timer, programmable buzzer/clock output (PCLBUZ0), and key interrupt support (6 inputs). All I/O pins support TTL input buffers, N-ch open-drain (6 V tolerant on P20–P23), and on-chip pull-up resistors - enabling direct interfacing with 1.8/2.5/3.3 V logic without level shifters.

FAQ

What is the maximum operating frequency of the R5F10269GSM#15?

The R5F10269GSM#15 supports a maximum system clock frequency of 24 MHz using its high-speed on-chip oscillator. This is achievable across its full industrial temperature range (–40°C to +105°C) with ±2.0% accuracy. External crystal operation is rated up to 20 MHz under the same conditions, and the device also supports lower-frequency modes including 15 kHz low-speed on-chip oscillator for ultra-low-power standby.

Does the R5F10269GSM#15 support background data flash programming?

Yes, the R5F10269GSM#15 supports background operation (BGO) for its 2 KB data flash memory. This allows the CPU to execute application code from program memory while simultaneously rewriting data flash sectors - essential for real-time logging, parameter updates, or firmware patching without interrupting control loops.

What package type and pin count does the R5F10269GSM#15 use?

The R5F10269GSM#15 uses a 20-pin TSSOP package (PTSP0020JI-A) with 4.4 × 6.5 mm body size and 0.65-mm lead pitch. It is lead-free and RoHS compliant. This compact surface-mount package supports high-density PCB layouts while maintaining compatibility with standard reflow soldering processes.

How many analog input channels does the R5F10269GSM#15 provide?

The R5F10269GSM#15 provides 11 analog input channels (ANI0–ANI3, ANI16–ANI22) with 10-bit resolution and an internal 1.45 V reference voltage. It also integrates a calibrated temperature sensor and supports differential input configurations using AVREFP/AVREFM pins - enabling precision measurement in thermal management and sensor fusion applications.

Is the R5F10269GSM#15 qualified for industrial temperature operation?

Yes, the R5F10269GSM#15 carries the 'G' suffix indicating qualification for industrial applications over –40°C to +105°C ambient temperature. This includes guaranteed performance of all specifications - including flash endurance, oscillator accuracy (±2.0% at +105°C), and I/O drive strength - across the full range, making it suitable for demanding environments like motor drives and factory controllers.
