Does the R5F10267GSP#35 include data flash memory?
Yes, the R5F10267GSP#35 includes 2 KB of data flash memory with background operation (BGO) capability, allowing program execution to continue while rewriting nonvolatile parameters. This feature is explicitly documented in the RL78/G12 datasheet Section 1.1 "Features" and Section 1.3.1 "Data Flash", distinguishing it from the R5F103xx series which omits data flash entirely.
How many serial communication interfaces does the R5F10267GSP#35 support?
The R5F10267GSP#35 supports one UART channel, two CSI (SPI-compatible) channels, and two simplified I²C interfaces - totaling five independent serial peripheral units. This configuration is specified in Section 1.7 "Outline of Functions" of the R01DS0193EJ0250 datasheet for 20-pin R5F1026x products, and enables concurrent communication with multiple sensors, displays, or host controllers.
Is the R5F10267GSP#35 pin-compatible with other RL78/G12 20-pin variants?
Yes, the R5F10267GSP#35 shares identical 20-pin TSSOP pinout and electrical characteristics with other R5F1026x and R5F1036x variants (e.g., R5F10268GSP#35, R5F10367GSP#35), as confirmed by Figure 1-1 and Table 1-1 in the R01DS0193EJ0250 datasheet. However, functional differences - such as presence of data flash or DMA - require firmware validation during substitution.
What safety features are integrated into the R5F10267GSP#35?
The R5F10267GSP#35 includes hardware CRC calculation, RAM guard, and SFR guard - all documented in Section 1.3.3 "Peripheral Functions" of the datasheet. These features detect memory corruption and unauthorized register access, supporting IEC 61508 SIL-2 readiness and enhancing reliability in industrial control applications where functional safety is required.
