FAQ
What is the maximum operating frequency of the R7FS7G27H3A01CFB#AA0?
The R7FS7G27H3A01CFB#AA0 operates at a maximum CPU frequency of 240 MHz using its ARM Cortex-M4F core. This rating is guaranteed under specified voltage (3.0–3.6 V) and temperature (–40°C to +85°C) conditions per the official S7G2 datasheet. The R7FS7G27H3A01CFB#AA0 achieves this speed with on-chip PLL configuration and supports dynamic clock scaling to reduce power during idle periods.
Does the R7FS7G27H3A01CFB#AA0 include an integrated Ethernet MAC?
Yes, the R7FS7G27H3A01CFB#AA0 integrates a full Ethernet MAC supporting RMII interface mode. It provides dedicated pins for CRS_DV, TX_EN, TXD0/1, RXD0/1, RX_ER, MDC, MDIO, and ETH_IRQ14#, enabling direct connection to external PHYs like the KSZ8081 on the SK-S7G2 board. The R7FS7G27H3A01CFB#AA0 does not include a PHY; external clocking (25 MHz crystal) and PHY IC are required for full Ethernet operation.
Can the R7FS7G27H3A01CFB#AA0 drive a QVGA LCD without external components?
Yes, the R7FS7G27H3A01CFB#AA0 integrates a complete LCD controller supporting 240×320 QVGA resolution with RGB888 output, programmable timing, and built-in display sequencer. On the SK-S7G2 board, it directly drives the HaoRan HT024K5QV50T panel using the ILI9341V interface - requiring only passive termination resistors and no external timing logic or frame buffer memory. The R7FS7G27H3A01CFB#AA0 handles all display refresh autonomously via DMA.
What debug interfaces are supported by the R7FS7G27H3A01CFB#AA0?
The R7FS7G27H3A01CFB#AA0 supports SWD (Serial Wire Debug) and JTAG interfaces via dedicated pins (TMS/SWDIO, TCK/SWCLK, TDO/SDDO, TDI, RESET). On the SK-S7G2 board, these are routed to both the onboard SEGGER J-Link debugger (J19 USB) and the external 20-pin JTAG/SWD header (J18). The R7FS7G27H3A01CFB#AA0 also supports Renesas' E2 studio and IAR Embedded Workbench for full source-level debugging and flash programming.
Is the R7FS7G27H3A01CFB#AA0 qualified for automotive applications?
No, the R7FS7G27H3A01CFB#AA0 is rated as a Standard-grade device per Renesas' quality classification and is intended for industrial, office, and consumer applications - not transportation or safety-critical systems. Its datasheet specifies operating temperature range of –40°C to +85°C and does not meet AEC-Q100 requirements. For automotive use, Renesas offers separate RH850 or RL78/F1x families; the R7FS7G27H3A01CFB#AA0 must not be deployed in vehicles, trains, or aircraft control systems.
