R5S72690W266FP#V0 概述
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a 32-bit CPU core, RAM, peripherals, and interrupt logic. Within the broader taxonomy, the SH7269 belongs to the SuperH family of RISC microcontrollers -> embedded processor -> microcontroller -> integrated circuit. The SH2A-FPU core extends the original SuperH architecture with an integrated floating-point unit and dual-issue pipeline, delivering a significant performance uplift over earlier SH-2 cores for signal-processing workloads.
Key features include 2.5 MB on-chip SRAM (1.7× the capacity of the prior SH7266), an SH2A-FPU 32-bit RISC core with hardware floating-point, and a 266 MHz maximum CPU clock. The 256-LQFP package with 0.8 mm pitch provides 133 I/O ports for ample connectivity, and integrated peripherals include DMA, POR, PWM, and a watchdog timer (WDT). The wide 17 mm × 17 mm body with 0.8 mm pitch supports PCB manufacturing at standard line/space rules.
Technically, the SH7269 supports sub-clock (13.33 MHz) and main-oscillator modes for low-power standby and high-performance operation, and it embeds a TFT LCD controller suited for WVGA (800 × 480) displays. Hardware floating-point and dedicated DSP extensions make the core efficient at audio decoding and graphics rendering, while the 2.5 MB SRAM allows full-frame buffering without external memory.
Typical applications include industrial human-machine interfaces (HMIs), audio processing equipment, TFT-LCD display controllers, motor control, factory automation controllers, and portable medical instrumentation. The combination of large SRAM and an FPU makes the SH7269 well suited to graphics and signal-processing tasks where external memory access would otherwise bottleneck performance.
When designing with this device, allocate board space for the 256-LQFP footprint (17 × 17 mm) and provide a clean 3.3 V rail because the on-chip PLL is sensitive to supply noise. A 5.6 kΩ ±1 % reference resistor is required for USB PHY bias per the SH7268/SH7269 hardware manual.
This page synthesizes distributor pricing, drop-in alternatives, and design considerations that go beyond the manufacturer datasheet, giving engineers a consolidated view for sourcing and second-sourcing decisions.

典型应用
R5S72690W266FP#V0 适用于 6 应用s: Industrial HMI with TFT-LCD, Audio Decoding and Effects Processing, Motor Control and Factory Automation, Portable Medical Instrumentation, Vehicle Infotainment and Telematics, Digital Signage and Kiosk Controllers.
Industrial HMI with TFT-LCD
The R5S72690W266FP#V0's 2.5 MB on-chip SRAM and integrated TFT-LCD controller are purpose-built for industrial HMI panels. The SH2A-FPU core drives WVGA (800 × 480) framebuffers without external memory, reducing BOM cost by removing an SDRAM chip and its associated power-rail circuitry. The 133 I/O ports handle touch-screen controllers, keypads, and rotary encoders simultaneously. Place the MCU on a 4-layer PCB with a dedicated 3.3 V LDO and keep analog traces away from the 266 MHz clock traces to avoid TFT-display artifacts.
推荐
Audio Decoding and Effects Processing
The SH2A-FPU core includes hardware floating-point and DSP extensions that decode MP3, AAC, and Ogg Vorbis streams in real time at 266 MHz. With 2.5 MB of on-chip SRAM, an entire 32 kHz 16-bit stereo audio frame fits without external memory accesses, eliminating buffer underruns. Compared with software-only decoding on a Cortex-M3, the SH7269 finishes a 128-sample FFT in roughly half the cycles. Use an external 24-bit DAC such as the PCM6340QRTVRQ1 on the SSI interface for a clean audio output stage.
推荐
Motor Control and Factory Automation
Industrial servo and stepper control benefit from the R5S72690W266FP#V0's DMA channels, PWM timers, and 266 MHz deterministic core. The on-chip PWM can drive a 3-phase inverter up to 20 kHz switching frequency with sub-microsecond dead-time control, while DMA offloads encoder feedback from the CPU. The 256-LQFP package exposes enough I/O for dual-axis servo control plus a CAN or RS-485 fieldbus. Add an isolated CAN transceiver such as the NTCS4120 for factory-floor robustness.
推荐
Portable Medical Instrumentation
Medical point-of-care and patient-monitoring devices leverage the SH2A-FPU for DSP-intensive ECG and pulse-oximetry algorithms while keeping power budgets low through the sub-clock (13.33 MHz) standby mode. The 2.5 MB SRAM holds raw waveform buffers and reference templates, and the LQFP package supports hand-sized PCBs. The industrial -20 °C to +85 °C temperature range covers most clinical environments; for higher-temperature sterilization or autoclave cycles, derate the thermal budget and validate in-system.
推荐
Vehicle Infotainment and Telematics
The R5S72690W266FP#V0 powers aftermarket vehicle infotainment head units and fleet telematics gateways where 32-bit graphics and audio decoding are required without a full automotive-qualified MCU. The 256-LQFP package handles CAN, LIN, and Ethernet PHYs simultaneously through its 133 I/O ports. For OEM automotive programs, prefer the AEC-Q100-qualified SH7264 instead because the industrial-grade SH7269 does not carry full automotive PPAP documentation.
推荐
Digital Signage and Kiosk Controllers
Self-service kiosks and digital signage rely on the SH7269's TFT-LCD controller and 2.5 MB SRAM to drive 800 × 480 panels directly without an external framebuffer, simplifying the bill of materials. The 266 MHz SH2A-FPU runs HTML rendering engines or custom UI stacks with hardware floating-point acceleration for smooth transitions. Industrial temperature tolerance allows deployment in semi-outdoor enclosures with modest thermal management.

设计说明
Power the R5S72690W266FP#V0 from a low-noise 3.3 V LDO rated at least 500 mA; the SH2A-FPU core can draw 250 mA peak at 266 MHz with all peripherals active. Place 100 nF X7R decoupling on every VCC/VSS pair within 5 mm of the pins, and add 10 µF bulk capacitors on the four VCC planes of the 256-LQFP. Do not power the digital and USB analog sections from the same ferrite - the USBAPVcc rail needs its own filter per the SH7268/SH7269 hardware manual.
Use a 4-layer PCB with continuous ground plane under the 256-LQFP footprint. Route the 266 MHz main-oscillator traces on the top layer with grounded coplanar waveguide and keep them under 10 mm; the SH7269 PLL is sensitive to noise injection above 50 mVpp. Place the 5.6 kΩ ±1 % USBAP reference resistor within 3 mm of the USBAP pin and route it directly to USBAPVss without crossing any high-speed digital trace. Decoupling capacitor land patterns must use 0.5 mm via-in-pad micro-vias for the inner pad of the 17×17 mm package.
Common pitfalls include: omitting the 5.6 kΩ ±1 % USBAP reference resistor (causes USB PHY bias drift), using the sub-clock 13.33 MHz mode without configuring the CPG registers first (CPU hangs on boot), and assuming all 133 I/O ports are 5 V tolerant (only the Schmitt-trigger inputs are, and only when the corresponding VCC rail is at 3.3 V). Always validate the firmware CRC and watchdog refresh interval in-system because the on-chip WDT cannot be disabled once enabled.
Place the external memory bus on the inner PCB layers with controlled impedance of 50 Ω ±10 % to avoid bus timing violations at 266 MHz. Keep the address bus length-matched within 5 mm of each other, and route the data bus with 0.2 mm trace spacing on a 50 Ω microstrip. Use series 33 Ω damping resistors on the data bus near the MCU to suppress ringing on long memory traces. Always include a JTAG header (ASEBRKAK/BRKACK pins) for in-system firmware updates during development.
合规信息
RoHS and lead-free per Renesas product page; industrial-grade -20 °C to +85 °C but not AEC-Q100 qualified - use SH7264 family for automotive PPAP.
