FAQ
What is the maximum operating frequency of the R5F10269GSP#V5?
The R5F10269GSP#V5 supports a maximum high-speed on-chip oscillator frequency of 24 MHz with ±1.0% accuracy over −20°C to +85°C. When using an external crystal (X1), it operates up to 20 MHz at VDD ≥ 2.7 V or 8 MHz at VDD ≥ 1.8 V. The minimum instruction execution time is 0.04167 µs at 24 MHz, enabling 31 DMIPS performance.
Does the R5F10269GSP#V5 include data flash memory?
Yes, the R5F10269GSP#V5 includes 2 KB of on-chip data flash memory with background operation (BGO) support, allowing concurrent code execution and data flash rewriting. It guarantees 1,000,000 rewrite cycles and operates across the full 1.8–5.5 V supply range - making it suitable for nonvolatile parameter storage in field-deployed devices.
What low-power modes are supported by the R5F10269GSP#V5?
The R5F10269GSP#V5 supports HALT (63 μA/MHz), STOP (0.52 μA typical), and SNOOZE modes. In STOP mode, the CPU and most peripherals halt while retaining RAM content and enabling wake-up via external interrupt or RTC alarm. SNOOZE mode keeps selected peripherals active (e.g., UART, ADC) while the CPU sleeps - ideal for periodic sensor polling.
Is the R5F10269GSP#V5 pin-compatible with other RL78/G12 20-pin variants?
Yes, the R5F10269GSP#V5 shares identical 20-pin LSSOP package dimensions, pin assignment, and electrical characteristics with other R5F102xxGSP#V5 and R5F103xxGSP#V5 variants. This allows drop-in replacement within the same temperature grade (G), provided firmware accommodates differences in flash size, RAM, and peripheral enablement.
What debugging interfaces does the R5F10269GSP#V5 support?
The R5F10269GSP#V5 supports on-chip debug via the TOOL0, TOOLRxD, and TOOLTxD pins using Renesas E2 emulator or compatible debug probes. It implements the standard RL78 on-chip debug interface with full breakpoint, watchpoint, and memory inspection capabilities - but Renesas advises against using debug features in mass-produced end products due to flash wear implications.
