Renesas SLG47912, SLG47920 & SLG47921 Low-Power Compact FPGAs
Compact, low-power FPGAs with Flexible Configuration and Secure Bitstream Support
The Renesas SLG47912, SLG47920, and SLG47921 are compact, low-power FPGA devices designed for space-constrained digital systems requiring flexible logic integration and efficient power management. These highly versatile devices support configuration through one-time programmable (OTP) non-volatile memory or via an SPI interface using an external bitstream source, allowing designers to optimize boot architecture and system flexibility.
With dense configurable logic arrays, integrated memory resources, and support for LVDS signaling, the SLG4791x family enables a broad range of applications across consumer, industrial, and portable electronics. Advanced power control features, multiple configuration modes, and strong security capabilities make these devices well suited for secure, low-power digital designs.
All three devices feature dual I/O voltage domains (1.71 V to 3.465 V) with a 1.1 V core supply, integrated 50 MHz high-frequency oscillator, PLL support, and flexible clock management. Security features include CRC integrity checks and AES bitstream decryption. Two ultra-low-power idle modes support state retention for GPIOs and BRAM while maintaining consumption below 85 µA.
